Maximum daily rations of the ctenophore Beroe ovata Brugière and predatory impacts on the Mnemiopsis leidyi A. Agassiz population were estimated via digestion time, prey biomass and predator and prey density in Sevastopol Bay and adjacent water regions. Digestion times ranged from 0.5 to 5.2 h and depended on the prey/predator weight ratio. Overall, the(More)
Data on the feeding of larvae of mass Black Sea fish species of the families Blenniidae and Gobiidae with a length of 2.2–7.0 mm from coastal waters of the Crimea (Sevastopol) are presented. Despite the tendency for an improvement in the feeding of larval fish, Mnemiopsis leidyi, in the case of a prolonged staying in the plankton in mass amounts in the(More)
The organic matter content in the eggs and early larvae of the ctenophores Mnemiopsis leidyi and Beroe ovata from the Black Sea was determined using the adapted microtechnique of dichromate oxidation. The content of organic matter in the eggs of M. leidyi (0.25 μg/indiv.) was 5 times less than in B. ovata (1.28 ± 0.29 μg/indiv.). The somatic content of(More)
The feeding rates of ctenophore Mnemiopsis leidyi were estimated using the data of the abundance and food composition in the inshore waters of the northwestern Black Sea in 2009–2010. The clearance rate varied in regard to the different foods. The maximum rates were observed when M. leidyi consumed Bivalvia veligers (400 L ind.−1 day−1); the minimum rates(More)
This paper studies the qualitative and quantitative food composition of the ctenophore Mnemiopsis leidyi A. Agassiz, 1865, as well as its feeding intensity and predatory impact on selected species of mesoplankton in the inshore waters of the northwestern Black Sea in 2008–2010. Interannual and interspecies differences in the intensity of the predatory(More)
