ABSTRACT
Understanding the relationship between river flows and levels and fish communities is important to setting minimum flow
and level regulations designed to prevent ecological harm. We reviewed a long-term Florida Fish and Wildlife Conservation
Commission data set from the Ocklawaha River, Florida, to evaluate trends in fish abundance and fish communities relative
to historical river levels. Fish data were collected using electrofishing at the Ocklawaha River, Florida, during 19831994.
Electrofishing data were used to estimate catch per minute and biomass per minute of selected species, fish diversity, richness
and evenness. Catch rate variables were compared among years and significant differences in abundance and community indices
