Abstract

Lysine is one of the essential amino acids and is important factor in the feed that affects the growth of fish. The objective of the present study is to determine the optimum percentage of lysine dietary in feed that able to produce maximum growth performance of silver pompano seed. These studies were done with four different treatments of additional lysine levels, ie- treatment A: 0.15%, treatment B: 0.35 %, treatment C: 0.55 % and K 0 % for control. The study design was completely randomized design with 4 treatments, each consisting of 3 replications. The results showed that feeding with different levels of lysine had no significant effect on body weight gain, feed consumption, absolute weight, feed conversion ratio or survival rate except for specific growth rate and lysine retention, which had a significant effect on fish fed treatment A (0.15%) or containing 3.39% lysine in feed.
