Abstract
Treatment of channel catfish (Ictalurus punctatus) production ponds with biweekly applications of 0.84 kg/ha copper sulfate was ineffective in reducing phytoplankton density. Three periodic applications of simazine totaling 1.3 mg/l drastically reduced phytoplankton density. However, extended periods of low dissolved O2 concentrations following simazine applications resulted in decreased fish yields and poor conversion ratios as compared to control ponds.This publication has 2 references indexed in Scilit:
