Oxidation Pond Algae as a Supplement for Commercial Catfish Feed

Investigations have shown that small (less than 10 cm) channel catfish fingerlings, Ictulurus punctatus Rafinesque, gained as much weight in a 10 week period on a diet of 25%-75% oxidation pond algae-commercial feed as did control animals fed 100% commercial feed. Larger fish (20-25 cm) fed the algal-supplemented diet did not gain as much weight in 10 weeks as did control fish on 100% commercial feed. Whole body protein and fat levels did not differ significantly between control and experimental fish.
