Estimation of length-weight relationship and condition factor of spotted snakehead Channa punctata (Bloch) under different feeding regimes

Comparative study was conducted to observe the efficacy of different feeding regimes on growth of Channa punctata . Six iso- proteinous diets were prepared by using different agro industrial by-products. Maximum weight gain was recorded with diet having 66.75% rice bran, 11.50% mustard cake, 23.0% g...

Description
Summary:Comparative study was conducted to observe the efficacy of different feeding regimes on growth of Channa punctata . Six iso- proteinous diets were prepared by using different agro industrial by-products. Maximum weight gain was recorded with diet having 66.75% rice bran, 11.50% mustard cake, 23.0% groundnut cake, 5% molasses, 1.5% vitamin-mineral mixture and 0.5% salt with specific growth rate of 0.408. The experimental fish recorded the value of exponent ‘b’ in the range of 2.7675 to 4.3922. The condition factor ‘K’ of all experimental fish was above 1.0 (1.094- 1.235) indicating robustness or well being of experimented fish.
