Effect of partial replacement of fish meal with palm kernel meal on growth performance and oxidative stress of Malaysian prawn,
Macrobrachium rosenbergii was evaluated. A closed aquaculture system with 21 fiberglass tanks with the capacity of 150 liter was
set up for the experiment. Five test diets were formulated by replacing 0, 10, 20, 30 and 40% fishmeal with palm kernel meal and
labeled as PKM0, PKM10, PKM20, PKM30 and PKM40, respectively. Another two diets were prepared by the supplementation of 2%
shrimp meal and 2% squid meal in PKM30 and PKM40 diets which designated as PKM30+ and PKM40+, respectively. All the test
diets were iso-nitrogenous (30% crude protein), iso-lipidic (12% crude lipid) and iso-energetic (19 KJ/g DM gross energy). Triplicate
groups of 30 post-larvae (0.041±0.001 g) were stocked in previously prepared tanks and fed the test diets at the rate of 20-30% of
their body weight, twice a day for 60 days. The results showed that there was no significant differences (P>0.05) in final weight (g),
percent weight gain (%) and specific growth rate (% per day) of prawn fed PKM0, PKM10, PKM20 and PKM30 diets. However, all
these growth parameters were significantly decreased in prawn fed PKM40 diet compared to fishmeal based control diet (PKM0).
Supplementation of crude attractants such as shrimp meal and squid meal recovered the depleted growth performances. It was found
that the above growth parameters were significantly improved in PKM30+ and PKM40+ diets compared to all other PKM diets. No
significant differences were also found between these groups of prawn and the control group. The feed conversion efficiency and
protein efficiency ratio also followed the similar trends where PKM40 showed significantly lowest values compared to the control.
The feed utilization parameters were significantly improved in PKM30+ and PKM40+ groups. The survival (%) was not significantly
affected by any of the dietary treatments. On the other hand, superoxide dismutase activity was similar in all the dietary treatments
except in PKM30. It is concluded that 30% fishmeal can be replaced with PKM in the diets of prawn without any detrimental effects
on growth performance and feed utilization. Supplementation of small amount of crude attractants such as squid meal, shrimp meal
etc could replace 40% or more fishmeal from the diet of Malaysian prawn.

On the quest of alternative protein sources, researchers have found insects to be nutritionally rich and among insects acridid
grasshoppers have a good future. In this context the present work concentrated to formulate various protein rich conventional
and acridid supplemented diets to feed the Japanese quail Coturnix japonica . The experiments were divided into two phases. In the
first phase various diets were prepared where fish meal was gradually replaced by acridid meal (i.e., 0%, 25%, 50%, 75%, and 100%
replacement). Consumption of the diet having 50% replacement of fish meal with acridid meal resulted higher feed utilization and
weight gain of the quails, however egg laying performance and meat quality was slightly better in the birds feeding on the diet having
75% acridid inclusion level than the one having 50% acridid inclusion level. This proved that at least 50% fish meal could be replaced
by acridid meal. In the second phase fish meal based, soybean meal based and acridid meal based diets were prepared. All of them had
three different inclusion levels of the major ingredients (i.e., 5%, 10%, and 15% of the diet). The growth and egg laying performance
of C. Japonica was better in most of the cases for 10% acridid meal added diet. This particular diet also gave better results compared
to the fish meal based and soybean meal based conventional diets without showing deleterious effect on flesh and egg quality. These
encouraging results successfully established acridid grasshoppers as an alternative protein source for poultry birds.
