摘要：
1. Gene products of 22 protein coding loci in two commercially used (domesticated) and one wild population of African catfish, Clarias gariepinus, were examined by horizontal starch-gel and vertical polyacrylamide-gel electrophoresis. 2. Average heterozygosities of 0.0759 and 0.0033 for the domesticated and 0.0467 for the wild catfish population were calculated. 3. Genetic distances indicated a greater similarity between geographically isolated (hatchery) populations than between hatchery and wild populations. 4. Selection of breeding stock for aquaculture practices based on the above information is discussed.
