  • Abstract:

Clarias gariepinus is a major cultivable fish species in Nigeria. The method of its propagation and quality of seed
produced is therefore crucial. In the present study, the effect of dietary supplementation of aqueous extract of Piper
guineense on the milt quality of male catfish, C. gariepinus broodstocks was investigated. Seventy five (75) male C.
gariepinus (mean weight ± 407.5 g) were fed with four diets supplemented with 0.6, 1.2, 1.8 and 2.4 g aqueous extract
of P. guineense dry fruit extract / 100 g feed respectively (designated as D2, D3, D4 and D5) and the control diet D1
was not supplemented. The experiment was carried out for a period of 70 days and the broodstocks were fed at 3%
body weight two times per day. Fish fed experimental diets showed significantly improved growth performance and
reproductive indices over the fish in control treatment. Higher (P < 0.05) gonadosomatic index was recorded for the
fish fed dietary P. guineense compared to fish fed on control diet. This result revealed that dietary supplementation of
P. guineense fruit aqueous extract significantly improved gonadosomatic index, milt volume, milt count, motility
duration, percentage motility, testosterone level and testicular histology of male C. gariepinus broodstocks, and it has
a potential pro-fertility effects which can be exploited in fish seed production by hatchery operators.
