Краткое описание

The content of stomach of 320 Mnemiopsis leidyi specimens was investigated in July 1992 at 26 stations in the Black Sea. The data on structures and concentration of mesozooplankton were used in analysis of the connection of Mnemiopsis feeding and conditions of the fodder base. A list of food objects is given. The comparison of quantitative feeding parameters in regions of different food abundance and at separate stations is conducted. Close connection of feeding parameters with food abundance is shown. Pleopis, Bivalvia larvae, and Copepoda were the most numerous in ctenophore's stomachs, They differ by ctenophore capturing efficiency due to different ability to avoid contact with Mnemiopsis tentacles. The distinctions in feeding intensity of specimens of different sizes and in different time of the day are shown.
