Evaluation of Three Low Frequency Electrofishing Pulse Rates for Collecting Catfish in Two Florida Rivers

We evaluated three low frequency electrofishing pulse rates (30, 15, and 7.5 pulses per second [pps]) for differences in relative abundance, size structure and species composition of catfish species in two north Florida rivers (Apalachicola and Suwannee). Three species of catfish were collected from each river: Apalachicola River-flathead catfish (Pylodictis olivaris), channel catfish (Ictalurus punctatus), and blue catfish (I. furcatus); Suwannee River-spotted bullhead (Ameiurus serracanthus), channel catfish, and white catfish (I. catus). In both rivers, the dominant catfish species (...
