Abstract

An investigation was carried out to assess the fecundity of Chagunius chagunio. A total of 50 gravid females were collected and then divided into various groups of length and weight, respectively. The fecundity ranged from 1,038 to 22,174 with a mean value of 6,201.46 ± 4,068.25 for a corresponding length and weight of 15.2 cm to 31 cm and 35.98 g to 427.99 g respectively. The fecundity increased with the total length, body weight, and ovary weight following the equation, Y = 1,081.59X-1,6025, (r = 0.76, 0.80, 0.90). The regression line for the TL, BW, GL, and GW of the sample fishes was linear when plotted against their fecundity. The present study’s findings will help recognize the proper breeding season of Chagunius chagunio.
