FEEDING OF SIBERIAN STURGEON Acipenser baeri (Brandt) UNDER POND CONDITIONS

Abstract

Diet composition and feeding intensity of pond-reared Siberian sturgeon fry 52-130 days old (average body mass 0.72-50.45 g, and average body length 50.2-215.4 mm) were analysed. Insecta larvae predominated in the gut contents of the fish, mainly Chironomidae and Ephemeroptera (Clo on dipterum). Additionally, some large cladocerans were found such as Ceriodaphnia sp., Moina sp., Daphnia longispina and Simocephalus sp. The weight of Insecta larvae eaten by the fish determined feeding intensity coefficients.
