Eutrophication as a driver of r‐selection traits in a freshwater fish. Issue 2 (12th June 2014) - Lin, M.
Abstract 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, the asymptotic length (L∞) and the growth performance index (IGRO) were significantly affected by eutrophication. The gonado‐somatic index (IG) and relative fecundity (FR) were significantly lower in mesotrophic lakes than in eutrophic and hypertrophic lakes. These results indicate that increasing eutrophication affects the life‐history tactics of a freshwater fish.
