- Abstract
The parameters of length-weight relationship Labeo fimbriatus were estimated from Vani Vilasa Sagara Reservoir, Chitradurga district, Karnataka. The regression co-efficient of male was found to be lower than female. From this observation it may be opined that female gained more weight in length compared to male. Even though 'b' values are around '3', it was found that there was significant difference between sex. Hence, separate equations for both the sex were derived. During 2013-14 the equations were for male 0.0182 L2.9427 and for females 0.0158 L2.9808 likewise, during 2014-15, the equations were W = 0.0197L2.8782 and 0.0161L2.9857 for male and female, respectively. Data on seasonal variation in condition factor (Kn) of both male and female during both the years of the study showed that the values were more or less similar in both the sex, indicating almost identical metabolic activity in male and female which may be attributed to gonadal development and high feeding intensity. The Kn values were observed in the range of 0.9902 to 1.0653 for males and 0.9996 to 1.0686 for female in different seasons. These parameters are useful to evaluate the wellbeing population, their biology for scientific management of fisheries and stock assessment.
