Zoological Institute, Russian Academy of Sciences (ZIN RAS), Universitetskaya nab. 1, 199034, St. Petersburg, Russia aut Changes in the diet of the coastal cod Gadus morhua marisalbi in the Kandalaksha Gulf of the White Sea under conditions of increased abundance of three-spined stickleback Gasterosteus aculeatus [Elektronische Daten] [P. Ershov] The data on feeding of coastal cod Gadus morhua marisalbi in the area of the Chupa Bay (Kandalaksha Gulf of the White Sea) are presented. In the food spectrum of cod, over 25 cm long fish and their eggs dominated (77.5% by frequency of occurrence and 91.7% by weight). Other groups of food organisms occupied a secondary place. Among fish, three-spined stickleback Gasterosteus aculeatus was the most prominent food item in the diet of cod (48.3% by weight). The published data on long-term changes of the diet of cod are considered, which are mostly related to considerable fluctuations of the abundance of three-spined stickleback in the White Sea. It is shown that, at present, three-spined stickleback again plays an important role in the diet of the White Sea cod Pleiades Publishing, Ltd., 2010 cod nationallicence diet nationallicence three-spined stickleback nationallicence the White Sea nationallicence Journal of Ichthyology SP MAIK Nauka/Interperiodica 50/1(2010-01-01), 84-88 0032-9452 50:1<84 2010 50 11489 https://doi.org/10.1134/S0032945210010108 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1134/S0032945210010108 text/html Onlinezugriff via DOI NATIONALLICENCE 100 1- Ershov P.
