Diet composition and transition of clearhead icefish( Protosalanx hyalocranius )in Lake Xingkai
Diet compositions of alien clearhead icefish( Protosalanx hyalocranius )in Lake Xingkai were investigated monthly from June 2010 through January 2011. Protosalanx hyalocranius preyed mainly on cladoceran, copepoda, shrimp, and larvae or juvenile fish. In June, P. Hyalocranius were smaller than 60 mm...
