Abstract
The impact of culture environment was assessed for the production of
GIFT tilapia over high stocking densities at 20 fish/m2 and 30 fish/m2 in ponds and
300 fish/ m3 and 400 fish /m3 in cages in the same ponds to ensuring maximum
utilization of the pond resources. After 120 days culture period the highest net yield
of 3.72 kg/ m2 was obtained from ponds which were stocked with 20 fish / m2 and fed
with homemade feed consisted of 60% wheat bran + 30% mustard oil cake +10%
flour, while the highest net yield of 8.55 kg / m3 was obtained from cages stocked
with 300 fish / m3 fed with the same feed from the same cultural environment. The
lowest net yields of 2.34 kg/ m2 and 8.48 kg/ m3 were recorded from fish stocked at
30 fish/ m2 and 400 fish / m3 fed with the same feed from ponds and cages
respectively. With the high survival rate the growth and yield of tilapia fish were
found to be significantly influenced (p <0.05) by the cultural environment, stocking
density and their interactions. Therefore the culture environment had a greater exerted
effect on the production than the stocking densities.
