Atrazine-Induced Impairment of Fecundity and Fertilization in Exposed Adult Clarias gariepinus: Consequences for Hatchability and Larval Survival
This research investigates the impact of atrazine, a widely used herbicide, on the reproductive capabilities of
adult Clarias gariepinus, a freshwater catfish of ecological and economic significance. Twelve months old specimens of C.
gariepinus comprising of twenty (20) males and twenty (20) females with mean average weight of 1024 ± 88.4g and 1100 ±
97.4g respectively and mean total length of 52.8 ± 2.3cm and 52.7 ± 1.1cm respectively, were exposed to exposed to four
different sub-lethal concentrations of atrazine (40µg/L, 60µg/L, 80µg/L, and 100µg/L) in a semi-static renewal assay.
