Catch per unit of effort (kg of fish / hour of sampling) versus total chlorophyll (mg/m3) and number of fish species collected versus surface area of lake for 60 Florida lakes sampled by Canfield and Hoyer (1992) (•) and Lake Sellers (Lake County) electrofishing sampling (o). The lines represent linear regressions for logged values of the 60 Florida lakes.
