Аннотация: Abstract—Kildin cod Gadus morhua kildinensis is a subspecies of Atlantic cod with extremely small populationsize, listed in the Red Data Book of the Russian Federation, which inhabits the waters of a smallmeromictic lake on the Kildin Island (Barents Sea). Comparative studies of morphobiological characteristicsand feeding habits of Kildin cod in the juvenile period were conducted for the first time. Comparison of samplesets of adult Kildin cod and fingerlings on the basis of multivariate analysis of variance demonstrates ahigh degree of differences in the complex of morphometric characters. The diet of the analyzed sample set ofKildin cod fingerlings consisted of ostracodes (Ostracoda), larvae of polychaetas (Polychaeta), cladocerans(Cladocera), and gammarids (Gammaridae). The special features of changes in the diet of Kildin cod in theearly ontogenesis are discussed.
