520 _aTilapia meal was produced from Oreochromis niloticus cultured in human waste (septage) fed ponds as part of a strategy for resource reuse . Tilapia meal was compared to two marine fish meal s in the complete diet of Penaeus monodon to evaluate it's relative quality a nd use in the production of a high value cultured shrimp species. A total of thirty (30) combination s of tilapia meal ( TM ) , High Quality ( HQF ) and Low Quality (LQF) fish meal were tested against PL42 juveniles of P . monodon in an unreplicated population 2 growth experiment . Stocking density was equivalent to 312 pieces / m2 in a recirculating brackish water aquaria system . Initial population mean weight was 0.243 g ( +/- 0.120), final population mean we ight of the best feed formulation (40% TM : 60% LQF : 0% HQF) was 2.01 g and the worst performer (0% TM : 10% LQF : 90% HQF) was 1.10 g. The specific growth rates (SGR) of each population were determined and used in linear and non - linear multiple regression analysis against proximate analysis parameters, gross energy : protein ratio, essential amino acid index and food conversion ratio. An insignificant fraction of the growth rate variability could be explained by the measured or calculated parameters. The SGR varied between 2 . 94% and 2.11% . Tilapia meal when compared to HQF and LQF can be considered neither inferior or superior. The results suggest that in a clear water, intensive culture system P. monodon requires nutrients that are not supplied by marine fish meals , but may be supplied by tilapia meal. Tilapia meal could offer a very attractive marine fish meal replacement in the future a nd can assist in sparing the higher priced fish meals produced from marine fish .
