Abstract
Catfish (Ictaluridae) breeding experiments conducted at Auburn University 1969–1981 are summarized. Strain comparisons and three major breeding programs (mass selection, intraspecific crossbreeding, and interspecific hybridization) were used to improve growth, survival, reproductive performance, disease resistance, seinability, vulnerability to angling, carcass yield, and tolerance to low dissolved oxygen. Different test environments (aquaria, cages, and ponds) were evaluated. Marking systems for fish identification were compared. Communal stocking and multiple-rearing were tested. Genetic and environmental components of variation were determined.
