Abstract
The reliance on expensive synthetic hormones and the ethical concerns of sacrificing potential breeders for pituitary gland (PG) extraction in African catfish (Clarias gariepinus) induced spawning necessitate exploring cost-effective and ethical alternatives. This study evaluated the efficacy of PG extracts from eel-tailed catfish (Tandanus tandanus) and Nile tilapia (Oreochromis niloticus) compared to African catfish PG. Twelve mature African catfish (approximately 500 g each) were divided into three treatment groups (n=4 per group), each receiving PG extracts standardized by donor fish weight. Spawning latency was recorded and analyzed using ANOVA and post-hoc tests. Results demonstrated that eel-tailed catfish PG (13.54 h) exhibited comparable spawning latency to African catfish PG (11.88 h), while Nile tilapia PG resulted in significantly longer latency (17.59 h). This suggests that eel-tailed catfish PG is a viable and cost-effective alternative to synthetic hormones and traditional PG extraction, offering a sustainable solution for African catfish hatcheries.
