Abstract

The purpose of the research is to reveal the regional variability of the gonadosomatic index of the Mullus barbatus ponticus surmullet (Essipov, 1927) and its relationship with climatic trends in the Black Sea-Mediterranean basin. Materials and methods. The work is based on biogeographical studies in the aquatic ecosystem, in particular, the results of complete biological analyses of surmullet caught in the southwestern shelf of the Crimea. Samples were taken in 2015-2023. Gonadosomatic index (GSI) and the stage of gonadal maturity were measured according to standard methods. The validity of the parameter diff erences was assessed by Student's t-test. Results and discussion. Climate change during the period under study, 2015-2023, showed that the fl uctuations in the average annual surface temperature of the sea in the Black Sea are higher than in the Aegean and Mediterranean Seas. It was found that in the northwestern part of the Black Sea, the correlation coeffi cient between GSI changes and temperature during the spawning period in the surmullet was r ≈ 0.7. It has been shown that climate changes in both the Black Sea and the Mediterranean basin infl uence the timing and intensity of spawning. Conclusions. Taking into account climate change in 2015-2023, in the Black Sea, a shift in spawning time from late spring to early spring was observed in the surmullet with the highest GSI value in June and a sharp decrease in July at temperatures above 24-25 °C. In Mediterranean seas, spawning was longer with lower GSI values.
