Abstract: This study examined the reproductive biology of
Hydrocynus forskahlii in the Lower River Benue with specific objectives of estimating sex ratio, gonadosomatic index (GSI) and fecundity. A total of 134 fish samples were collected biweekly at Wadata landing site between November 2022 to January 2023. Samples were collected from catches of fishermen and were immediately placed in ice boxes and transported to the laboratory for analysis. Results showed a female-to-male sex ratio of 1.52:1. GSI was highest in December with corresponding increases in gonad weight (2 g) and body weight of 600 g. Fecundity ranged from 3,700 to 9,059 eggs (
p< 0.05) with December recording the highest mean fecundity (9,059±723 eggs). R² value of 0.9536 was recorded between body weight and fecundity. Larger females contributed more significantly to the population of
H. forskahlii with seasonal GSI peaks that were stimulated by favourable environment factors.
