Abstract
Specimens of Salmostoma untrahi (Day) collected from backwaters of Bhadra reservoir were studied for their biology during 1998-1999. The length-weight relationships calculated from 719 specimens were Log W = - 5. 2766 + 3.0392 L and Log W = - 5. 1110 + 2.9606 L for males and females, respectively. The seasonal fluctuations in the relative condition factor (Kn) of both the sexes could be attributed to the seasonal sexual cycle, spawning and intake of food. Qualitative and quantitative analysis of food revealed that the fish was predominantly a herbivore feeding mainly on desmids and blue-greens. Higher gonado-somatic index values were noticed in the month of October, April and June. Ova diameter studies indicated more than one modal group of developing ova in the advanced stage of maturity. Males matured at 108-113 mm, while females matured at 88 mm. The fish has got prolonged spawning season extending throughout the year. The peak spawning occured in July, October and February. The fish spawned more than once in a year. The sex-ratio (male : female) was 1:0.50 with males dominating in most of the size groups and months.
