Abstract

На основе ежемесячного пробоотбора 2007-2010 гг. изучен аминокислотный состав перифитона и макрозообентоса на литоральной станции в среднем течении р. Енисей. Выявлены сезонные колебания профиля аминокислот в перифитоне, которые могут быть связаны с сезонной сукцессией видов микроводорослей. Обнаружены достоверные различия аминокислотного состава у различных видов речного зообентоса. Показана несбалансированность аминокислотного профиля макрозообентоса в сравнении с его пищей – перифитоном – в отношении двух незаменимых аминокислот – лизина и гистидина. Оценена питательная ценность для рыб недавно вселившегося в реку Енисей гаммаруса, относительно вытесняемых им эндогенных видов – личинок ручейников и хирономид

Аmino acid (AA) composition of periphyton and zoobenthos of the shallow part in the middle section of the Yenisei River on the basis of monthly sampling during 2007-2010 was studied. Seasonal variations in the amino acid profile of periphyton were detected, which may be related to seasonal succession of microalgae species. Pronounced differences in AA compositions of different species of riverine zoobenthos were found. The imbalance in amino acid profile of macrozoobenthos compared to its food, that is periphyton, in respect of two essential amino acids – lysine and histidine, was shown. The nutritional value of Gammarus – the recent invader in the studied section of the Yenisei River was evaluated and compared to that of indigenous taxa – trichopteran and chironomid larvae
