| Abstract/Description: | The knowledge on the reproductive biology of fish (Linnaeus, 1758) in riverine condition is meagre in the Indian sub-continent which is necessary for the development of an appropriate fishery management protocols for the rivers. In this context, the gonadal maturation profile and fecundity of was studied. Mature, spawning and spent females recorded in almost all the months of the year evidenced multiple and prolonged breeding behaviour. An overall sex ratio (M/F) of 1: 1.08 observed was statistically non-significant from expected 1:1 ratio ( =6.994219, p=0.8642) indicating that males and females were statistically equal in number. The absolute fecundity ranged from1192 to 4760 with mean of 2590 eggs from ovary weighing between1.91 g to 28.89 g. Monthly changes in gonado-somatic index (GSI) revealed that fish bred throughout the year except in July and August, but at peak between October- November and March-June. Size at first maturity of male was estimated as 229.6 mm with confidence limit of 235.9 and 223.6 mm and for female as 238.1 mm with confidence limit of 244.7 and 231.7 mm, respectively. |
