REPLACEMENT OF FISH MEAL PROTEIN BY SOY BEAN AND CORN GLUTEN MEAL PROTEINS IN THE DIET OF MUD CRAB, Scylla paramamosain
Abstract: Mud crab culture
relies heavily on trash fish as the main source of feed ingredients. Artificial
diets have been developed for mud crab and most of them have high content of
fish meal. The increasing cost and demand of fish meal has encouraged feed
manufacture to search for cheaper alternative protein sources such as plant
protein. There is an urgent need to find suitable alternative protein sources
to reduce the dependence of fish meal in mud crab diet. The objective of this
study was to develop compounded feeds for juvenile of mud crab with reduced
fish meal content, and as an alternative of trash fish feeding. For that
reason, the experiment was done. Experimental diets were fish meal, 20% of soy
bean (20% SBP), 40% of soy bean (40% SBP), 20% of corn gluten (20% CGP), and
40% of corn gluten meal protein (40% CGP). Average initial mud crab body weight
of 0.65 ± 0.03 g was fed experimental diets for 56 days. The result showed that
dietary fish meal protein can be replaced by 20% of soy bean and 20%–40% of
corn gluten proteins for mud crab (Scylla paramamosain) diet. Thus, it can
arguably be concluded that soy bean and corn gluten proteins are the
alternative protein sources to partially replaced fish meal.
