Graded levels of manganese were supplemented to a semi-purified diet containing 45% crude protein
to provide six levels of manganese (i. e. containing 5
25
50
70
140 and 210×10−6
respectively) for two experiments with these experimental diets. The initial weight of shrimp used in the 35–day experiment I was 0.30±0.04 g
and that in the 70–day Experiment II was more than one gram. The results showed that optimum content in the semi-purified diet for the more than 1 gram shrimp ranged from 70 ×10−6
to 140×10−6
but supplementation of Mn was not necessary for the small shrimp.
