    This study aimed to produce mechanically separated meat (MSM) from tilapia obtained at the Teresina fish market in the state of Piauí, Brazil. Waste production and disposal and yields were estimated, and physico-chemical and microbiological MSM qualities were determined. A questionnaire was applied to the fish market sellers, followed by tilapia carcass sampling for MSM production and assessments concerning yields, microbiological (Escherichia coli and Staphylococcus coagulase positive counts and the detection of Salmonella spp.) and physicochemical (water activity, pH, reaction to hydrogen sulfide and ammonia) quality and proximate composition (moisture, ash, proteins, lipids, carbohydrates and total energy value). The questionnaire results indicated that tilapia is highly in demand and thats processing leads to significant waste. The yield analysis indicated that tilapia MSM presents adequate residual meat extraction rates from tilapia carcasses. All microbiological analyses were in compliance with Brazilian standards. Physicochemical results were as follows: protein (14.9 to 16.1%), lipids (16.6 to 22.1%), ash (1.3 to 2.8%), moisture (60.6 to 64 .1%), carbohydrates (0.6 to 1.5%) and calories (216.5 to 263.1 kcal 100-1). It is, therefore, clear that MSM constitutes a safe and nutritious foodstudd and comprises a viable alternative for the development of co-products.

    RESUMO Para ajustar a frequência alimentar de juvenis de cobia ou beijupirá (Rachycentron canadum), 540 juvenis, com peso médio de 2,0 g (± 0,4) e comprimento médio de 8,7cm (± 0,5), foram distribuídos em quatro tratamentos: T2, T4, T6 e T8 (alimentação realizada duas, quatro, seis e oito vezes ao dia, respectivamente). Cada tratamento teve três repetições. Os juvenis de beijupirá foram alimentados em regime ad libitum. Observou-se diferença significativa no peso final (P0,05) entre os tratamentos. Assim, para juvenis de beijupirá, observou-se que a frequência de alimentação de oito refeições por dia, juntamente com um regime de alimentação ad libitum, é a mais adequada durante essa fase. Os dados obtidos no presente experimento permitem otimizar uma etapa da cadeia produtiva do beijupirá.

    ABSTRACT L-carnitine perform a major role in transporting long-chain fatty acids into the mitochondria, where they are oxidized. It has been used in animal diets to decrease fat and increase muscle protein. The aim of this study was to evaluate the zootechnical performance, degree of steatosis in the liver, and genotoxic potential in Astyanax lacustris fed with different levels of L-carnitine (LC). Yellowtail tetra juveniles (n = 140) were distributed in 20 tanks of 70 L, with seven fish in each, in a water recirculation system with controlled temperature (27±0.1⁰C). The treatments with different levels of L-carnitine supplementation were: 0 (control), 250, 500, 750, and 1000 mg of LC per kg of food. The diets were provided twice a day for 60 days. The results showed that the different levels of LC did not affect (P>0.05) weight gain, survival, viscerosomatic index, and the liver hepatocytes showed a normal appearance. However, the use of LC supplementation showed genotoxic potential with a significant difference (P0,05) o ganho de peso; a sobrevivência, o índice viscerossomático e os hepatócitos do fígado apresentaram-se com aparência normal. No entanto, a suplementação com LC apresentou potencial genotóxico com diferença significativa (P<0,05) para alterações celulares quando comparada ao controle em concentrações superiores a 500mg kg-1.

    ABSTRACT Different anesthetic agents are commonly used during procedures performed in aquaculture to minimize stress and maximize fish welfare during handling. A Kinguio fish was treated with a history of a mass near the left eye. In the clinical evaluation, a pedunculated neoformation was found in the periocular region. The fish was submitted to anesthesia for surgical removal of the mass, which was later referred to histopathological evaluation, revealing myxoma. The anesthesia protocol used 1% propofol at a concentration of 5 mg/liter of water and morphine at a dose of 5 mg/kg, intramuscularly. Immediately after the end of the procedure, the fish was returned to the aquarium and its anesthetic recovery was observed. The objective of this report is to describe a surgical procedure in kinguio fish and to determine the efficacy of propofol associated with morphine in this species. As a result, complete immobilization of the fish was obtained with propofol, reaching the fourth stage of anesthesia and the administration of morphine suggested being able to provide effective and long-lasting analgesia. It is concluded that despite the positive results obtained, anesthesia in fish still needs to be extensively investigated to refine analgesia protocols during procedures that cause pain and stress. RESUMO Diferentes agentes anestésicos são usados durante procedimentos realizados na aquicultura para minimizar o estresse e maximizar o bem-estar dos peixes durante o processo de manejo. Um peixe kinguiu foi atendido com histórico de presença de uma massa próxima ao olho esquerdo. Na avaliação clínica, constatou-se uma neoformação pedunculada na região periocular. O peixe foi submetido à anestesia para remoção cirúrgica da massa, que posteriormente foi encaminhada para avaliação histopatológica, a qual revelou mixoma. Como protocolo de anestesia, utilizou-se propofol 1% diluído em água, na concentração de 5mg/litro, e morfina, na dose de 5mg/kg, na concentração de 10mg/mL, intramuscular. Imediatamente após o procedimento, o peixe foi devolvido ao aquário para observação da recuperação anestésica. O objetivo deste relato é descrever um procedimento cirúrgico em peixe kinguio e determinar a eficácia do propofol associado à morfina nessa espécie. Como resultados, obteve-se a imobilização completa do peixe com o uso do propofol, atingindo o quarto estágio da anestesia, e a administração da morfina sugeriu ser capaz de proporcionar analgesia eficaz e duradoura. Conclui-se que, apesar dos resultados positivos obtidos, a anestesia em peixes precisa ainda ser bastante investigada para refinar os protocolos de analgesia durante os procedimentos que causam dor e estresse.

    ABSTRACT: In recent decades, Aeromonas hydrophila has emerged as a foodborne bacterial pathogen of public health concern, especially as it exhibits resistance to the major chemical sanitizers commonly used in the food industry. Meanwhile, this pathogen may be spread from diseased fish flesh through the contamination of equipment contact surfaces during food processing, thus posing a food safety risk. Thise determined the susceptibility profiles of retail fish-borne A. hydrophila isolates to 24 common antibiotics and five major sanitizers used in the food industry. The polymerase chain reaction technique was used to confirm all A. hydrophila isolates to the species level, and the agar diffusion method was applied to determine the antimicrobial susceptibility profiles. All isolates were confirmed to be A. hydrophila species. This bacterium was observed to have resistance to multiple antibiotics, with the highest resistance index being for those of the beta-lactam class. Additionally, the isolates showed high resistance to four of the five chemical sanitizers tested, with the highest resistance rate being toward sodium hypochlorite. The results suggested that A. hydrophila isolates with multiple resistance to the antimicrobials and main sanitizers used in the food industry can be found in retail fish sold in the Cuiabá region of Mato Grosso, Brazil. RESUMO: Aeromonas hydrophila emergiu nas últimas décadas como um patógeno humano relevante. O fato desse patógeno alimentar emergente apresentar resistência antimicrobiana é um desafio considerável para as Agências de Saúde devido à resistência desta espécie aos principais sanitizantes químicos comumente utilizados na indústria alimentícia em que representa um risco à segurança dos alimentos, uma vez que pode contribuir para a disseminação desta bactéria na carne de peixes e levar à contaminação da superfície de contato dos equipamentos durante o processamento dos alimentos. Este estudo teve como objetivo determinar os padrões de suscetibilidade de isolados de A. hydrophila de peixes comercializados no varejo a 24 antibióticos comuns e cinco principais sanitizantes utilizados nas indústrias alimentícias. Neste estudo, todos os isolados de A. hydrophila foram confirmados em nível de espécie pela técnica de Reação em Cadeia da Polimerase (PCR). A técnica de difusão em ágar foi utilizada para determinar o perfil de suscetibilidade antimicrobiana frente aos 24 antibióticos testados e para avaliar a suscetibilidade aos principais sanitizantes utilizados na indústria alimentícia. A partir dos resultados, todos os isolados foram confirmados como sendo da espécie A. hydrophila pela técnica de PCR molecular. Observou-se A. hydrophila com perfil de resistência a múltiplos antibióticos, em que os da classe dos Beta-Lactâmicos foram os antimicrobianos com maior índice de resistência. Além disso, a suscetibilidade aos sanitizantes apresentou alta resistência em quatro dos cinco sanitizantes testados, sendo o hipoclorito de sódio foi o sanitizante químico com maior índice de resistência entre os isolados deste estudo. Os resultados sugerem que isolados de A. hydrophila com perfil de resistência a antimicrobianos e aos principais sanitizantes utilizados na indústria alimentícia podem ser encontrados em peixes comercializados no varejo da região de Cuiabá/Mato Grosso.

    ABSTRACT This study investigated the effects of dietary supplementation with Mansoa alliacea hydroalcoholic extracts on growth, blood and immune parameters of Arapaima gigas. Fish were fed for 30 days with diets enriched with 0, 4, 8, and 12 g kg-1 of M. alliacea hydroalcoholic extract and subjected to infection with Aeromonas hydrophila and handling stress. Fish fed with 8 g kg-1 of extract showed significant increase in final weight, specific growth rate and feed efficiency when compared to the other groups. Glucose, triglycerides, total proteins, and globulins increased significantly in fish fed with 8 g kg-1 of extract, whereas albumin decreased. The number of thrombocytes increased significantly with the dietary supplementation of 8 and 12 g kg-1 of extract. After the challenge with A. hydrophila and handling stress, fish fed with 8 g kg-1 of extract had significantly higher levels of glucose, globulins, and albumins, and fish fed with 8 and 12 g kg-1 of extract showed an increment of respiratory burst. Triglyceride levels dropped significantly in fish fed with 4, 8, and 12 g kg-1 of extract, whereas the number of neutrophils increased, and total thrombocytes, leukocytes and lymphocytes were higher in fish fed with 12 g kg-1 of extract. Dietary supplementation with M. alliacea extract at 8 g kg-1 was efficient in improving the growth and innate immunity of A. gigas, being potentially useful in fish farming to control the development of A. hydrophila infections. RESUMO Investigou-se os efeitos da suplementação com extrato hidroalcólico de Mansoa alliacea sobre o crescimento e parâmetros sanguíneos e imunológicos de Arapaima gigas. Os peixes foram alimentados por 30 dias com dietas enriquecidas com 0, 4, 8 e 12 g kg-1 de extrato hidroalcoólico de M. alliacea e submetidos à infecção por Aeromonas hydrophila e estresse de manejo. Os peixes alimentados com 8 g kg-1 de extrato apresentaram aumento significativo no peso final, taxa de crescimento específico e eficiência alimentar quando comparados aos demais grupos. Glicose, triglicerídeos, proteínas totais e globulinas aumentaram significativamente nos peixes alimentados com 8 g kg-1 de extrato, enquanto a albumina diminuiu. O número de trombócitos aumentou significativamente com a suplementação dietética de 8 e 12 g kg-1 de extrato. Após infecção com A. hydrophila e estresse de manejo, os peixes alimentados com 8 g kg-1 de extrato apresentaram níveis significativamente mais altos de glicose, globulinas e albuminas, e os peixes alimentados com 8 e 12 g kg-1 de extrato apresentaram incremento de explosão respiratória. Os níveis de triglicerídeos decresceram nos peixes alimentados com 4, 8 e 12 g kg-1 de extrato, enquanto o número de neutrófilos aumentou, e o número total de trombócitos, leucócitos e linfócitos foi maior nos peixes alimentados com 12 g kg-1 de extrato. A suplementação com a 8 g kg-1 de extrato de M. alliacea foi eficiente em melhorar o crescimento e a imunidade inata de A. gigas, sendo potencialmente útil na piscicultura para controlar o desenvolvimento de infecções por A. hydrophila.

    Abstract The decision whether the bipotential gonadal anlage will become a testis or ovary is a critical step during sex determination and differentiation in fish. This process involves a complex and coordinated genetic cascade, which result in the differentiation of the somatic cells into ovary or testis. In this context, important genes of TGF-β superfamily appears have a pivotal role in this biological process of fish development. In this review, we showed the breakthrough in the last decades that engage the Anti-Müllerian hormone (Amh) as an important effector in this decision. Here we exposed studies with different species of fishes around of world have paved the way for clarifying the role of Amh in the regulation of the germ cells proliferation, which may influence the spermatogenesis and, sex determination and differentiation decision on teleost fish.

    Abstract This study identified the marine protected areas (MPAs) affected by the most extensive oil spill recorded on the Southwestern Atlantic coast, Brazil (2019/2020). We found that 81 MPAs suffered the direct or indirect effects of spilled oil, producing chemical, biological and socioenvironmental impacts over approximately 3.0% of the 2,659 protected areas currently established in Brazil. Although estimates suggest a moderate volume of spilled oil, the incident reached wide coastal strips, probably producing more damage to MPAs than other cases worldwide. Further, the generated negative impacts affected the already fragile environmental protection system in Brazil, potentially leading to negative impacts on global networks of MPAs and worldwide biodiversity.

    Abstract To assist the reproductive management of tambaqui (Colossoma macropomum) males in laboratory and commercial fish farming, a linear regression model was obtained from concentration curves using the spectrophotometric method. Twenty-two tambaqui males with an average age of three years old were selected and divided into two groups containing 11 animals each. Both groups alternately received a single dose of carp pituitary extract (CPE; 2.0 mg/kg body weight, intracoelomic). Sperm was collected 14 h after hormonal treatment and diluted (1:4000; sperm:formaldehyde saline). The concentration was estimated by counting spermatozoa in a Neubauer chamber and by using a spectrophotometer (λ=540 nm). Individual sperm concentration ranged from 11.40 to 71.13 × 109 sperm/mL. The degree of transmittance ranged from 62.1% to 95.0%. There was a significant correlation (r2 = 0.966; p < 0.0001) between sperm concentration analyzed in a Neubauer chamber and transmittance at 540 nm. Analysis by spectrophotometry and the prediction provided by the equation Y=100.293 - 0.509X proved to be an efficient and fast method for estimating sperm concentration in tambaqui and can be used in routine procedures in artificial fish reproduction laboratories. Resumo Visando auxiliar o manejo reprodutivo de machos de tambaqui (Colossoma macropomum) em piscicultura de laboratório e comercial, obteve-se um modelo de regressão linear a partir de curvas de concentração por método espectrofotométrico. Foram selecionados 22 machos de tambaqui com idade média de três anos. Eles foram divididos em dois grupos contendo 11 animais cada. Ambos os grupos receberam alternadamente uma única dose de extrato de hipófise de carpa (EHC; 2,0 mg/kg de peso corporal, intracelomático). O esperma foi coletado 14 horas após o tratamento hormonal e diluído (1:4000; esperma: solução salina formaldeído). A concentração foi estimada por contagem de espermatozoides em câmara de Neubauer e por espectrofotômetro (λ=540 nm). A concentração espermática individual variou de 11,40 a 71,13 × 109 espermatozoides/mL. O grau de transmitância variou de 62,1 a 95,0%. Houve correlação significativa (r2 = 0,966; p < 0,0001) entre a concentração espermática analisada em câmara de Neubauer e a transmitância em 540 nm. A análise por espectrofotometria e a predição pela equação Y=100,293 - 0,509X mostrou ser um método eficiente e rápido para estimar a concentração espermática de tambaqui, podendo ser utilizado em procedimentos de rotina em laboratórios de reprodução artificial de peixes.

    Abstract The assessment of water quality using multiple abiotic and biological indicators is very important for understanding anthropogenic impacts and the health of the ecosystem. The Olaria is a short river system that flows into the Cananeia estuary. This aquatic system crosses the urban center of the city of Cananeia, where it eventually receives untreated domestic wastewater. This study aims to apply multi-indicators of environmental pollution to understand the influence of the Olaria system on the Cananeia estuary. For this purpose, indicators of water quality and genotoxic and pathological responses in fish were used. Data on salinity, pH, and silicates in surface water indicate a more accentuated continental influence in the inner part of the Olaria river system. Moreover, the data recorded on the inner area of the Olaria system, which presents lower hydrodynamic characteristics and the largest urban population, indicated the presence of dissolved oxygen and nutrients (phosphate [P-PO4 -3], nitrite [N-NO2-], and ammonium [N-NH4+]) at levels that exceed the established limits for water quality by the Brazilian environmental legislation (Conselho Nacional do Meio Ambiente - CONAMA). The presence of Escherichia coli in all analyzed water samples indicates a local or point source of domestic wastewater contamination near the Olaria system. Fish species such as Centropomus undecimalis (Robalo Flexa) and Sphoeroides testudineus (Baiacu Pintado) showed toxicogenetic damage, indicating clastogenic and/or aneugenic exposure in the aquatic environment. Hepatic pathologies such as pyknosis nuclei, inflammation, hepatocyte swelling, and necrosis were found in all specimens evaluated, and C. undecimallis exhibited all these pathological changes. These results highlight the importance of biomonitoring the effects of anthropogenic disturbance on the aquatic biota that frequent the Olaria system and are dependent on the water quality.

    This study aimed to produce mechanically separated meat (MSM) from tilapia obtained at the Teresina fish market in the state of Piauí, Brazil. Waste production and disposal and yields were estimated, and physico-chemical and microbiological MSM qualities were determined. A questionnaire was applied to the fish market sellers, followed by tilapia carcass sampling for MSM production and assessments concerning yields, microbiological (Escherichia coli and Staphylococcus coagulase positive counts and the detection of Salmonella spp.) and physicochemical (water activity, pH, reaction to hydrogen sulfide and ammonia) quality and proximate composition (moisture, ash, proteins, lipids, carbohydrates and total energy value). The questionnaire results indicated that tilapia is highly in demand and thats processing leads to significant waste. The yield analysis indicated that tilapia MSM presents adequate residual meat extraction rates from tilapia carcasses. All microbiological analyses were in compliance with Brazilian standards. Physicochemical results were as follows: protein (14.9 to 16.1%), lipids (16.6 to 22.1%), ash (1.3 to 2.8%), moisture (60.6 to 64 .1%), carbohydrates (0.6 to 1.5%) and calories (216.5 to 263.1 kcal 100-1). It is, therefore, clear that MSM constitutes a safe and nutritious foodstudd and comprises a viable alternative for the development of co-products.

    RESUMO Para ajustar a frequência alimentar de juvenis de cobia ou beijupirá (Rachycentron canadum), 540 juvenis, com peso médio de 2,0 g (± 0,4) e comprimento médio de 8,7cm (± 0,5), foram distribuídos em quatro tratamentos: T2, T4, T6 e T8 (alimentação realizada duas, quatro, seis e oito vezes ao dia, respectivamente). Cada tratamento teve três repetições. Os juvenis de beijupirá foram alimentados em regime ad libitum. Observou-se diferença significativa no peso final (P0,05) entre os tratamentos. Assim, para juvenis de beijupirá, observou-se que a frequência de alimentação de oito refeições por dia, juntamente com um regime de alimentação ad libitum, é a mais adequada durante essa fase. Os dados obtidos no presente experimento permitem otimizar uma etapa da cadeia produtiva do beijupirá.

    ABSTRACT L-carnitine perform a major role in transporting long-chain fatty acids into the mitochondria, where they are oxidized. It has been used in animal diets to decrease fat and increase muscle protein. The aim of this study was to evaluate the zootechnical performance, degree of steatosis in the liver, and genotoxic potential in Astyanax lacustris fed with different levels of L-carnitine (LC). Yellowtail tetra juveniles (n = 140) were distributed in 20 tanks of 70 L, with seven fish in each, in a water recirculation system with controlled temperature (27±0.1⁰C). The treatments with different levels of L-carnitine supplementation were: 0 (control), 250, 500, 750, and 1000 mg of LC per kg of food. The diets were provided twice a day for 60 days. The results showed that the different levels of LC did not affect (P>0.05) weight gain, survival, viscerosomatic index, and the liver hepatocytes showed a normal appearance. However, the use of LC supplementation showed genotoxic potential with a significant difference (P0,05) o ganho de peso; a sobrevivência, o índice viscerossomático e os hepatócitos do fígado apresentaram-se com aparência normal. No entanto, a suplementação com LC apresentou potencial genotóxico com diferença significativa (P<0,05) para alterações celulares quando comparada ao controle em concentrações superiores a 500mg kg-1.

    ABSTRACT Different anesthetic agents are commonly used during procedures performed in aquaculture to minimize stress and maximize fish welfare during handling. A Kinguio fish was treated with a history of a mass near the left eye. In the clinical evaluation, a pedunculated neoformation was found in the periocular region. The fish was submitted to anesthesia for surgical removal of the mass, which was later referred to histopathological evaluation, revealing myxoma. The anesthesia protocol used 1% propofol at a concentration of 5 mg/liter of water and morphine at a dose of 5 mg/kg, intramuscularly. Immediately after the end of the procedure, the fish was returned to the aquarium and its anesthetic recovery was observed. The objective of this report is to describe a surgical procedure in kinguio fish and to determine the efficacy of propofol associated with morphine in this species. As a result, complete immobilization of the fish was obtained with propofol, reaching the fourth stage of anesthesia and the administration of morphine suggested being able to provide effective and long-lasting analgesia. It is concluded that despite the positive results obtained, anesthesia in fish still needs to be extensively investigated to refine analgesia protocols during procedures that cause pain and stress. RESUMO Diferentes agentes anestésicos são usados durante procedimentos realizados na aquicultura para minimizar o estresse e maximizar o bem-estar dos peixes durante o processo de manejo. Um peixe kinguiu foi atendido com histórico de presença de uma massa próxima ao olho esquerdo. Na avaliação clínica, constatou-se uma neoformação pedunculada na região periocular. O peixe foi submetido à anestesia para remoção cirúrgica da massa, que posteriormente foi encaminhada para avaliação histopatológica, a qual revelou mixoma. Como protocolo de anestesia, utilizou-se propofol 1% diluído em água, na concentração de 5mg/litro, e morfina, na dose de 5mg/kg, na concentração de 10mg/mL, intramuscular. Imediatamente após o procedimento, o peixe foi devolvido ao aquário para observação da recuperação anestésica. O objetivo deste relato é descrever um procedimento cirúrgico em peixe kinguio e determinar a eficácia do propofol associado à morfina nessa espécie. Como resultados, obteve-se a imobilização completa do peixe com o uso do propofol, atingindo o quarto estágio da anestesia, e a administração da morfina sugeriu ser capaz de proporcionar analgesia eficaz e duradoura. Conclui-se que, apesar dos resultados positivos obtidos, a anestesia em peixes precisa ainda ser bastante investigada para refinar os protocolos de analgesia durante os procedimentos que causam dor e estresse.

    ABSTRACT: In recent decades, Aeromonas hydrophila has emerged as a foodborne bacterial pathogen of public health concern, especially as it exhibits resistance to the major chemical sanitizers commonly used in the food industry. Meanwhile, this pathogen may be spread from diseased fish flesh through the contamination of equipment contact surfaces during food processing, thus posing a food safety risk. Thise determined the susceptibility profiles of retail fish-borne A. hydrophila isolates to 24 common antibiotics and five major sanitizers used in the food industry. The polymerase chain reaction technique was used to confirm all A. hydrophila isolates to the species level, and the agar diffusion method was applied to determine the antimicrobial susceptibility profiles. All isolates were confirmed to be A. hydrophila species. This bacterium was observed to have resistance to multiple antibiotics, with the highest resistance index being for those of the beta-lactam class. Additionally, the isolates showed high resistance to four of the five chemical sanitizers tested, with the highest resistance rate being toward sodium hypochlorite. The results suggested that A. hydrophila isolates with multiple resistance to the antimicrobials and main sanitizers used in the food industry can be found in retail fish sold in the Cuiabá region of Mato Grosso, Brazil. RESUMO: Aeromonas hydrophila emergiu nas últimas décadas como um patógeno humano relevante. O fato desse patógeno alimentar emergente apresentar resistência antimicrobiana é um desafio considerável para as Agências de Saúde devido à resistência desta espécie aos principais sanitizantes químicos comumente utilizados na indústria alimentícia em que representa um risco à segurança dos alimentos, uma vez que pode contribuir para a disseminação desta bactéria na carne de peixes e levar à contaminação da superfície de contato dos equipamentos durante o processamento dos alimentos. Este estudo teve como objetivo determinar os padrões de suscetibilidade de isolados de A. hydrophila de peixes comercializados no varejo a 24 antibióticos comuns e cinco principais sanitizantes utilizados nas indústrias alimentícias. Neste estudo, todos os isolados de A. hydrophila foram confirmados em nível de espécie pela técnica de Reação em Cadeia da Polimerase (PCR). A técnica de difusão em ágar foi utilizada para determinar o perfil de suscetibilidade antimicrobiana frente aos 24 antibióticos testados e para avaliar a suscetibilidade aos principais sanitizantes utilizados na indústria alimentícia. A partir dos resultados, todos os isolados foram confirmados como sendo da espécie A. hydrophila pela técnica de PCR molecular. Observou-se A. hydrophila com perfil de resistência a múltiplos antibióticos, em que os da classe dos Beta-Lactâmicos foram os antimicrobianos com maior índice de resistência. Além disso, a suscetibilidade aos sanitizantes apresentou alta resistência em quatro dos cinco sanitizantes testados, sendo o hipoclorito de sódio foi o sanitizante químico com maior índice de resistência entre os isolados deste estudo. Os resultados sugerem que isolados de A. hydrophila com perfil de resistência a antimicrobianos e aos principais sanitizantes utilizados na indústria alimentícia podem ser encontrados em peixes comercializados no varejo da região de Cuiabá/Mato Grosso.

    ABSTRACT This study investigated the effects of dietary supplementation with Mansoa alliacea hydroalcoholic extracts on growth, blood and immune parameters of Arapaima gigas. Fish were fed for 30 days with diets enriched with 0, 4, 8, and 12 g kg-1 of M. alliacea hydroalcoholic extract and subjected to infection with Aeromonas hydrophila and handling stress. Fish fed with 8 g kg-1 of extract showed significant increase in final weight, specific growth rate and feed efficiency when compared to the other groups. Glucose, triglycerides, total proteins, and globulins increased significantly in fish fed with 8 g kg-1 of extract, whereas albumin decreased. The number of thrombocytes increased significantly with the dietary supplementation of 8 and 12 g kg-1 of extract. After the challenge with A. hydrophila and handling stress, fish fed with 8 g kg-1 of extract had significantly higher levels of glucose, globulins, and albumins, and fish fed with 8 and 12 g kg-1 of extract showed an increment of respiratory burst. Triglyceride levels dropped significantly in fish fed with 4, 8, and 12 g kg-1 of extract, whereas the number of neutrophils increased, and total thrombocytes, leukocytes and lymphocytes were higher in fish fed with 12 g kg-1 of extract. Dietary supplementation with M. alliacea extract at 8 g kg-1 was efficient in improving the growth and innate immunity of A. gigas, being potentially useful in fish farming to control the development of A. hydrophila infections. RESUMO Investigou-se os efeitos da suplementação com extrato hidroalcólico de Mansoa alliacea sobre o crescimento e parâmetros sanguíneos e imunológicos de Arapaima gigas. Os peixes foram alimentados por 30 dias com dietas enriquecidas com 0, 4, 8 e 12 g kg-1 de extrato hidroalcoólico de M. alliacea e submetidos à infecção por Aeromonas hydrophila e estresse de manejo. Os peixes alimentados com 8 g kg-1 de extrato apresentaram aumento significativo no peso final, taxa de crescimento específico e eficiência alimentar quando comparados aos demais grupos. Glicose, triglicerídeos, proteínas totais e globulinas aumentaram significativamente nos peixes alimentados com 8 g kg-1 de extrato, enquanto a albumina diminuiu. O número de trombócitos aumentou significativamente com a suplementação dietética de 8 e 12 g kg-1 de extrato. Após infecção com A. hydrophila e estresse de manejo, os peixes alimentados com 8 g kg-1 de extrato apresentaram níveis significativamente mais altos de glicose, globulinas e albuminas, e os peixes alimentados com 8 e 12 g kg-1 de extrato apresentaram incremento de explosão respiratória. Os níveis de triglicerídeos decresceram nos peixes alimentados com 4, 8 e 12 g kg-1 de extrato, enquanto o número de neutrófilos aumentou, e o número total de trombócitos, leucócitos e linfócitos foi maior nos peixes alimentados com 12 g kg-1 de extrato. A suplementação com a 8 g kg-1 de extrato de M. alliacea foi eficiente em melhorar o crescimento e a imunidade inata de A. gigas, sendo potencialmente útil na piscicultura para controlar o desenvolvimento de infecções por A. hydrophila.

    Abstract The decision whether the bipotential gonadal anlage will become a testis or ovary is a critical step during sex determination and differentiation in fish. This process involves a complex and coordinated genetic cascade, which result in the differentiation of the somatic cells into ovary or testis. In this context, important genes of TGF-β superfamily appears have a pivotal role in this biological process of fish development. In this review, we showed the breakthrough in the last decades that engage the Anti-Müllerian hormone (Amh) as an important effector in this decision. Here we exposed studies with different species of fishes around of world have paved the way for clarifying the role of Amh in the regulation of the germ cells proliferation, which may influence the spermatogenesis and, sex determination and differentiation decision on teleost fish.

    Abstract This study identified the marine protected areas (MPAs) affected by the most extensive oil spill recorded on the Southwestern Atlantic coast, Brazil (2019/2020). We found that 81 MPAs suffered the direct or indirect effects of spilled oil, producing chemical, biological and socioenvironmental impacts over approximately 3.0% of the 2,659 protected areas currently established in Brazil. Although estimates suggest a moderate volume of spilled oil, the incident reached wide coastal strips, probably producing more damage to MPAs than other cases worldwide. Further, the generated negative impacts affected the already fragile environmental protection system in Brazil, potentially leading to negative impacts on global networks of MPAs and worldwide biodiversity.

    Abstract To assist the reproductive management of tambaqui (Colossoma macropomum) males in laboratory and commercial fish farming, a linear regression model was obtained from concentration curves using the spectrophotometric method. Twenty-two tambaqui males with an average age of three years old were selected and divided into two groups containing 11 animals each. Both groups alternately received a single dose of carp pituitary extract (CPE; 2.0 mg/kg body weight, intracoelomic). Sperm was collected 14 h after hormonal treatment and diluted (1:4000; sperm:formaldehyde saline). The concentration was estimated by counting spermatozoa in a Neubauer chamber and by using a spectrophotometer (λ=540 nm). Individual sperm concentration ranged from 11.40 to 71.13 × 109 sperm/mL. The degree of transmittance ranged from 62.1% to 95.0%. There was a significant correlation (r2 = 0.966; p < 0.0001) between sperm concentration analyzed in a Neubauer chamber and transmittance at 540 nm. Analysis by spectrophotometry and the prediction provided by the equation Y=100.293 - 0.509X proved to be an efficient and fast method for estimating sperm concentration in tambaqui and can be used in routine procedures in artificial fish reproduction laboratories. Resumo Visando auxiliar o manejo reprodutivo de machos de tambaqui (Colossoma macropomum) em piscicultura de laboratório e comercial, obteve-se um modelo de regressão linear a partir de curvas de concentração por método espectrofotométrico. Foram selecionados 22 machos de tambaqui com idade média de três anos. Eles foram divididos em dois grupos contendo 11 animais cada. Ambos os grupos receberam alternadamente uma única dose de extrato de hipófise de carpa (EHC; 2,0 mg/kg de peso corporal, intracelomático). O esperma foi coletado 14 horas após o tratamento hormonal e diluído (1:4000; esperma: solução salina formaldeído). A concentração foi estimada por contagem de espermatozoides em câmara de Neubauer e por espectrofotômetro (λ=540 nm). A concentração espermática individual variou de 11,40 a 71,13 × 109 espermatozoides/mL. O grau de transmitância variou de 62,1 a 95,0%. Houve correlação significativa (r2 = 0,966; p < 0,0001) entre a concentração espermática analisada em câmara de Neubauer e a transmitância em 540 nm. A análise por espectrofotometria e a predição pela equação Y=100,293 - 0,509X mostrou ser um método eficiente e rápido para estimar a concentração espermática de tambaqui, podendo ser utilizado em procedimentos de rotina em laboratórios de reprodução artificial de peixes.

    Abstract The assessment of water quality using multiple abiotic and biological indicators is very important for understanding anthropogenic impacts and the health of the ecosystem. The Olaria is a short river system that flows into the Cananeia estuary. This aquatic system crosses the urban center of the city of Cananeia, where it eventually receives untreated domestic wastewater. This study aims to apply multi-indicators of environmental pollution to understand the influence of the Olaria system on the Cananeia estuary. For this purpose, indicators of water quality and genotoxic and pathological responses in fish were used. Data on salinity, pH, and silicates in surface water indicate a more accentuated continental influence in the inner part of the Olaria river system. Moreover, the data recorded on the inner area of the Olaria system, which presents lower hydrodynamic characteristics and the largest urban population, indicated the presence of dissolved oxygen and nutrients (phosphate [P-PO4 -3], nitrite [N-NO2-], and ammonium [N-NH4+]) at levels that exceed the established limits for water quality by the Brazilian environmental legislation (Conselho Nacional do Meio Ambiente - CONAMA). The presence of Escherichia coli in all analyzed water samples indicates a local or point source of domestic wastewater contamination near the Olaria system. Fish species such as Centropomus undecimalis (Robalo Flexa) and Sphoeroides testudineus (Baiacu Pintado) showed toxicogenetic damage, indicating clastogenic and/or aneugenic exposure in the aquatic environment. Hepatic pathologies such as pyknosis nuclei, inflammation, hepatocyte swelling, and necrosis were found in all specimens evaluated, and C. undecimallis exhibited all these pathological changes. These results highlight the importance of biomonitoring the effects of anthropogenic disturbance on the aquatic biota that frequent the Olaria system and are dependent on the water quality.
