Reproductive Success of Channel Catfish in a Farm Situation

Three thousand pair of hand selected, 3-year-old channel catfish (Ictalurus punctatus) were stocked in 4 ponds used for brood production in Humphreys County, Mississippi. From 1 May to 13 July 1981, data were obtained on spawning in the ponds. As the water temperature increased, so did the number of spawns up to a maximum of 498 on 30 May. Total spawns and spawning rate were 603 (86% )-pond 9; 523 (75%) -pond 10; 440 (55% )-pond 11; 550 (69% )-pond 12.
