Citation: STRAUS, D.L. SPECIES SENSITIVITY TO COPPER SULFATE: CHANNEL CATFISH AND HYBRID-STRIPED BASS.. AQUACULTURE AMERICA CONFERENCE. 2003. p.279. Technical Abstract: Copper sulfate is used extensively in aquaculture as an algicide and a therapeutant for protozoan parasites in commercial and recreational fish ponds. The acute toxicity of copper to many species has been studied however there is no data for hybrid striped bass (female white bass Morone chrysops x male striped bass M. saxatilis). Neither is there a comparison of acute toxicity of copper to channel catfish (Ictalurus punctatus) and hybrid striped bass under conditions that would exclude differences in water quality. The present study was designed to do this. Channel catfish and hybrid striped bass juveniles were exposed to copper sulfate in a static toxicity test conducted simultaneously using the same water source. Estimates of mean 96-hr LC50 values will be discussed. The results will confirm whether or not hybrid striped bass are more sensitive to copper than channel catfish.
