Effect of partial replacement of fishmeal with aquatic weed Pistia stratiotes meal on growth, biochemical composition, haematological parameters and digestive enzymes in Indian major carp Labeo rohita (Hamilton, 1822)

Abstract: 80 days experiment was conducted to determine the growth, biochemical, haematological and digestive enzyme performance of Labeo rohita (1.25± 0.12 g), fingerlings fed with Water Lettuce, Pistia stratiotes young leaf meal. The fingerlings were fed with a control (0% P. stratiotes) and five different experimental diets, containing 10%, 20%, 30%, 40% and 50% of P. stratiotes meal in place of fish meal as protein source and named as P0, P10, P20, P30, P40 and P50 respectively. There was a significant difference (P<0.01) in growth, biochemical, haematological parameters and digestive enzyme activities of different treatment groups. Maximum weight gain, specific growth rate and better feed conversion were noticed in P30. Maximum protein and fat accretion were witnessed in P30 group. These results clearly showed that L. rohita fed with diet 30% P. stratiotes meal in the diet perform better than rest of the experimental groups. Hence, this study proved that although fishmeal is non-replaceable, but can be supplemented with P. stratiotes meal up to an optimum level (30%) to produce cost effective fed for L. rohita.
