摘要: This study tested whether eutrophication could influence life-history traits of a cyprinid, Chanodichthys erythropterus, in 10 Chinese lakes. Using the von Bertalanffy growth model, asymptotic length (L-infinity) and performance index (I-GRO) were significantly affected by eutrophication. The gonado-somatic (I-G) relative fecundity (F-R) lower mesotrophic lakes than eutrophic hypertrophic These results indicate that increasing affects tactics freshwater fish.
