Aquatic weed supplementation for common carp (Cyrinuscarpio Var. Communis) fingerlings to ascertain growth and survival. Animal Nutrition and Feed Technology, 22: 673–678. Aquatic weeds namely hornwort (Ceratophyllum demersum), longleaf pondweed (Potamogeton nodosus) and fringed water lily (Nymphoides peltata) were analyzed for proximate composition. Crude protein (%) in N. peltata was (25%) comparatively higher than P. nodosus (22.57%) and C. demersum (24.15%). Similarly, the percentage dry matter was high in N. peltata (93.60%) as compared to P. nodosus (91.50%) and C. demersum (90.46%). Four isonitrogenous (CP:35%) and isocaloric (3500 kcal/kg) diets were formulated and N. peltata was added @ 0% (control) 15% (T1), 30% (T2) and 45% (T3). Fish with an average weight (8.95 + 1.1 g.) were fed diets at 5% body weight for 8 weeks. The fishes of T3 group had higher (P< 0.05) weight gain and specific growth rate as compared to the control group. Feed conversion ratio (FCR) decreased (P<0.05) in fish fed T3 diet. Highest survival rate was observed in control group. It can be concluded that N. peltata up to 45% in the diet of common carp, improved growth performance.
