Abstract

Resident crawfish were harvested in ponds used to culture prawns and/or catfish fingerlings in the summers of 1979 and 1980. Stocking rates were: prawns, 25,000/ha, 1979; 25,000 or 50,000/ha, 1980; catfish fry, 50,000/ha, 1979; 150,000/ha, 1980. P. clarkii was dominant but P. a. acutus was abundant in some ponds. Crawfish yeilds were 136-443 kg/ha, 1979, and 338-636 kg/ha, 1980. Differences were attributed to pond management practices, presence of prawns, and harvesting methods. In another, related study, resident crawfish were harvested from ponds stocked in September 1980 with 10-15 cm catfish fingerlings at rates of 1785, 3573, 8073, or 14,285/ha. P. clarkii dominated most ponds but many P. a. acutus were present. Ylelds were 192-1207 kg/ha with minimal differences attributable to catfish stocking densities. Green sunfish, Lepomis cyanellus, contamination was the primary factor affecting crawfish production.
