Studies on the effects of changes in weather conditions on the gonadosomatic index and some reproductive performance of African catfish were carried out with the aims of determining the fecundity, gonadosomatic index, fertilisation, hatchability and survival of the fish bred during (hot, rainy and cold periods). Eighteen broodstocks- comprising nine males and nine females were procured and conveyed to the Teaching and Research Fish Farm of the Department of Fisheries, University of Maiduguri and tested for their reproductive performance in each of the periods of the season; hot, rainy and cold time in April, August and January respectively. Data was analyzed using analysis of variance at a 95% confidence level. The results showed the highest fecundity, gonadosomatic index and number of fertilized eggs in the hot period while the number of hatched eggs and percentage survival were higher in the rainy period. Therefore, the most suitable periods that Clarias gariepinus can be bred are both hot and rainy periods as they give better results in terms of the reproductive performance of the fish.
