Abstract

Protein is a main component in the aquafeed, and it has traditionally been supplied from fish meal. However, other animal protein sources such as shrimp head meal and meat and bone meal are also potential to be used as a protein source to replace fish meal in the fish feed including feed for abalone. Therefore, this study aimed to evaluate alternative protein sources mainly from animals to replace fish meal in the diet on the growth of abalone Haliotis squamata. Four experimental diets were formulated to contain fish meal (FM) as a control diet, shrimp head meal (SM), meat and bone (MBM), and a mixture of fish meal, shrimp head meal and meat and bone meal (MIX). The experimental diets were fed once a day at a level 1.5% of total body weight to triplicate groups of abalone. Two hundred and forty abalone with an initial average weight 3.55 g and shell length 28.59 mm were distributed into 12 rectangular plastic baskets at a density of 20 abalone. After twelve weeks feeding trial, growth parameters of abalone fed fish meal (FM) diet were not significantly different than other diets. Therefore, our findings suggest that fish meal could be totally or partially replaced by shrimp head meal or meat and bone meal.
