摘要：The gut contents analysis of lake anchovy (Coilia ectenes) and ice fish (Neosalanx tangkahkii taihuensis) showed that the Pianka diet overlap value between these two species of planktivorous fish was 0.474. The commercial harvest of these two species during the recent two decades showed a significant negative correlation.
