Variation in Fish Community Composition, Biomass, and Harvest Relative to Environmental Parameters in Reservoirs of North and South Carolina

Creel survey and cove rotenone data from 17 reservoirs in Piedmont North and South Carolina were subjected to correlation and regression analysis to examine environmental factors influencing fish production and taxonomic composition and to develop models for the prediction of total harvest and biomass. Summer surface chlorophyll concentration was the best univariate predictor of total harvest (r2 = 0.93) and one of the best predictors of total biomass (r2 = 0.79). The morphoedaphic index was a good predictor of both biomass (r2 = 0.79) and harvest (r1 = 0.83), but explained no more...
