Abstract
A 40-day experiment was conducted to determine the effects of feeding level on growth and feed conversion efficiency in silver sea bream with an average initial body weight of 86 g. The fish were fed a commercial feed at different feeding rates from 1.0 to 2.5% (with 0. 5% increments) of body wet weight per day (w/day) at 23.1+1.1”C. Each feeding rate was administered to groups of 20 fish. Growth rate, as measured by the percent body weight increase, and condition factor increased with increasing ration. Feed efficiency was better at 1.5% ration. There was no difference in feed efficiency between fish fed 2.0 and 2.5% w/ day, under the applied meal programme. Based on the growth and feed efficiency data, optimum feeding rate was estimated to be 1.22% w/day.
