Effects of partial replacement of fishmeal protein with green seaweed (Cladophora spp.) protein in practical diets for the black tiger shrimp (Penaeus monodon) postlarvae

This study assessed the effects of the green seaweed Cladophora spp. as a protein source to substitute fishmeal protein in practical diets for postlarval tiger shrimp ( Penaeus monodon ). A control diet without containing seaweed meal was compared with five experimental diets in which fishmeal prote...

Description
Summary:This study assessed the effects of the green seaweed Cladophora spp. as a protein source to substitute fishmeal protein in practical diets for postlarval tiger shrimp ( Penaeus monodon ). A control diet without containing seaweed meal was compared with five experimental diets in which fishmeal protein was replaced by increasing the levels of green seaweed protein (10, 20, 30, 40 and 50%) in the diets. All diets were formulated to be equivalent in crude protein (40%) and lipid (7%). Each dietary treatment was replicated in triplicate. After 45 days of the feeding trial, survival of the shrimp was not significantly influenced by the feeding treatments ( p  > 0.05). Growth rates of the shrimp fed with 10, 20, or 30% replacement levels of green seaweed protein in the diets were superior or similar to those fed with the control diet whereas shrimp fed with the diet containing 40 and 50% substitution levels showed significant reduction in growth ( p
