Abstract
The effects of varying energy and kilka oil levels on the performances of
Indian prawn Penaeus indicus were evaluated in a 35 day experimental period
in three water salinities (25, 35 and 45 ppt). For each salinity, four
experimental diets with energy levels of 3500, 3800,4 1 00 and 4400kcallkg,
each containing three kilka (C/upeonel/a de/icatu/a) oil levels of 2, 4, 6%
(totaling 1 2 experimental diets) were fonnulated using Lindo softwear
program. All diets were isonitrogenous (40% protein) and fed at 8 percent of
body weight to 3 6 groups of 200 juvenile shrimps (P. indicus) in each level of
salinity. The results showed that under 25 ppt salinity, the diet containing
4 100 kcaV kg with 4% kilka oil showed the best results. For 35 ppt, 3800
kcaV kg with kilka oil level of 6 % was the suitable energy level. At 45 ppt, the best result was observed for the shrimp fed with 3500 kcall kg at 6% kilka
oil level. It thus appeared that energy requirement vary with salinity. It also
revealed that the energy to protein ratio of 1 1 0-1 1 8 kcaU g proteins was the
most suitable ratio for the growth of the shrimp under different salinities. The
incorporation of kilka oil in the diet as a source of energy and essential fatty
acids showed a satisfactory growth performance of the prawn. The n-3 fatty
acid of shrimp body tissue increased with the increasing the dietary n-3 fatty
acid levels.
