fresh and low saline waters. For successful farming of freshwater prawns,
nutritionally balanced cheap diet is a prime necessity. The present study was
designed to develop a nutritionally balanced feed for freshwater prawn by using
cuttlefish liver as a cheap source of lipid.
In this study juveniles of Macrobrachium rosenbergii were used for
evaluating the effect of various levels of lipid on growth, food conversion ratio,
survival rate, protein utilization and body composition. For this six experimental
diets designated as T 1 to T 6 were prepared by using clam meat, groundnut oil cake,
wheat bran, tapioca powder, vitamin mineral mixture and cellulose powder. Test
diets (T2 to T6) were prepared by adding different levels (l to 5%) of cuttlefish liver
lipid with an increment of 1 % by replacing equal amount of cellulose powder. Total
lipid content of the diets T\, T2, T3, T4, r, and T6 were 7.53%, 8.61%, 9.85%,
10.73%,12.01% and 13.41%, respectively. Completely randomized design with six
treatments each having three replications was used for analyzing the results. Ten
numbers of juveniles were randomly distributed in each tank Feeding w<..;c done for a
period of 60 days.
Test animals fed with a diet containing 2% of cuttlefish liver lipid with a
total lipid content of 9.85% showed better growth, food conversion efficiency and
protein utilization. But survival rate was not affected by the addition of cuttlefish
liver lipid. The protein content of body of test animals was maximum for the
treatment, T3 having 2% cuttlefish liver lipid. Lipid and moisture contents of the body
were at desirable levels for this treatment. Hence, it is found that, the diet containing 2%
of cuttlefish liver lipid with a total lipid of9.85% is good for M rosenbergii.
