| Abstract | Tilapia 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 . |
