Abstract The effectiveness of potassium ricinoleate as a selective blue-green algicide was investigated in experimental channel catfish, Ictalurus punctatus , culture ponds. Five ponds were treated with 0.8 mg/l potassium ricinoleate three times per week from May through October and five ponds served as controls. Treatment did not affect concentrations of chlorophyll- a , total and un-ionized ammonia-nitrogen, or dissolved oxygen; nor did it affect average hours of supplemental aeration or net fish production. The mean nitrite-nitrogen concentration in control ponds was higher ( P
