Abstract
A 200 year time series of scyphomedusae occurrence in the northern Adriatic was analysed using the wavelet technique to assess the major periodicities. The analysis of the historical time series revealed that four scyphomedusae, A. aurita, C. hysoscella, C. tuberculata and R. pulmo, have been present regularly in the northern Adriatic over the last 200 years, with two major periods of jellyfish proliferations. The first period in the years around 1910was characterised by common significant periodicity of 8 to 12 years. In the second period, from the late 1970' onward, two common periodicities were revealed, those shorter than 8 years and a longer one of 20-30 years.
