Phytoplankton Communities in Channel Catfish Ponds
Phytoplankton communities of commercial catfish ponds in westcentral Alabama were usually dominated by green algae (Chlorophyta). Blue-green algae, which were usually the dominant forms of algae in channel catfish ponds at the Auburn University Research Unit (east-central Alabama), were seldom present in great abundance in the commercial fish ponds. The pond waters in west-central Alabama had total alkalinity values of 69-148 mg/liter as CaC03 while total alkalinity values were much lower (lO to 15 mg/ liter) in pond waters on the Fisheries Research Unit. Difference in total alkalinity...
