To study the effect of Leucaena leucocephala leaf meal (LLM) in diet of Liza parsia on feed intake, growth and digestibility, feeding trials were conducted in fibre reinforced plastic (FRP) tanks containing 400 litre strained clear brackish water with four groups of Liza parsia fry in triplicates having twenty five fishes of average wt. ranging from 1.51 to 1.79 g per replicate. Pellet feeds (iso-proteinous) with three different levels of LLM i.e. 10%(LLM10), 20% (LLM20) and 30% (LLM30) were formulated and prepared using locally available feed ingredients and fed to fishes of group II, III and IV, respectively and compared with fishes of group I fed test diet containing no LLM (LLM0). In every morning leftover feed was siphoned out and 50% of water of rearing tank was exchanged. After 154 days of experiment it was found that average daily weight gain(ADG), feed conversion ratio (FCR), protein efficiency ratio (PER) and specific growth rate (SGR) did not differ significantly among the groups. Nutrient (organic matter, crude protein, ether extract) digestibility did not differ significantly among the groups. Carcass composition of fishes of four groups also did not differ. Histopathological study of liver tissues showed that liver tissue degeneration took place when Leucaena leucocephala leaf meal was incorporated beyond 10% level. Hence it is concluded thatLeucaena leucocephala leaf meal (CP-22.68%) can be incorporated up to 10% in diet of Liza parsia without affecting performance of fish.
