502			_aPresent experiment was conducted in 8 aquaria of size 1.5ft x 2ft x 3ft (width, height and length, respectively) with 1.5 feet water level in each aquarium on fingerlings of Ctenopharyngodon idella. Sun dried different parts of water hyacinth was used to prepare three isoproteic diets (30%) i.e. whole plant meal diet (WP), leaf meal diet (LM), root meal diet (RM) and a control diet. Overall significant (p. 0.05) difference was observed in weight and length among the treatments. On termination of experimental trial, all the fish were harvested, weighed and measured for assessment of growth performance. Representative samples from each treatment were randomly picked up for determination of body composition and histological studies. Former were dried for proximate analysis while latter were dissected, liver and kidney were excised out for further tissue processing. Statistically non-significant variations in increase in weight and length were recorded among Control, WP and LM diets while RM depressed fish growth. Mean weight 4.636}0.605g and length 78.757}3.995mm were relatively higher when grass carp juveniles were fed with LM and the same were the lowest 2.465}0.178g and 65.405}1.877mm, respectively, for RM diets. Higher weight gain was observed in LM (7.14 g) and lower on RM (2.10 g). Maximum length increase was observed on WP (50 mm) and minimum on RM (20 mm). Better FCR was observed on LM (2.113}0.102) and poor on RM (5.142}0.212). SGR % was observed maximum on LM (0.787}0.051) and minimum on RM (0.415}0.041). Histological study showed that there was no variation in liver and kidney in the Control diet whereas variations in cell patterns have been observed due to incorporation of water hyacinth which may be due to inherent toxic materials present in water hyacinth or due to some 61 heavy metals it absorbed from the surroundings. This research exposes that Eichhornia crassipes meal has an optimistic nutrient utilization effect on fish growth. Farmers can use water hyacinth to formulate cost-effective fish feeds. Water hyacinth leaf meal is more appropriate for fish production than the whole plant meal. But farmer has to be very careful and make sure that water hyacinth to be used in feed should come from clean water, because water hyacinth can absorb heavy metals and poisons from polluted water. Such plants if used in fish feed will affect the fish health and farmer profit.
