1 Total # of species = 15.
2 Weights calculated using regressions from Hoyer and Canfield 1994 and from Bill Schaeffer, Florida Fish and Wildlife Conservation Commission (personal communication).




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 Butler (Orange County) electrofishing sampling (o). The lines represent linear regressions for logged values of the 60 Florida lakes.
