1. Development of feeding stimulants- Effect of adding amino acids to soy-protein baseddiets on growth of cobia.The objective of this study is to determine the effectiveness of amino acids as afeeding stimulant adding to soy-protein based diets for cobia. Soy-protein based dietssupplemented with amino acids also can improve the nutrition value and reduce the costof diets.2. The study of improvement diet for cobia-The utilization of carbohydrate.The aim of this study will be investigated the utilization of different levels flour dietsin cobia, these data will be able to get basic information to improvement the artificialfeed for cobia.3. Effects of dietary carnitine inclusion on the growth and flesh quality of hybrid tilapia.Dietary carnitine supplementation was found to improve growth in several fishspecies, and also been shown that dietary carnitine supplements reduced the lipidcontent of liver and muscle in several species. By contrast, dietary carnitinesupplementation did not affect growth performance in salmonids, nor did it reduce bodylipid content in several species. This study is conducted to investigate the effect of dietarycarnitine supplementation on the growth and body lipid distribution of hybrid tilapia.4. The effect of feed additive on growth performance and body lipid distribution of silverperch.The use of low fish meal and high energy diets is a current practice in theaquaculture industry, as these diets have been considered beneficial for economic andnutritional reasons. However, such diet with high levels of alternative plan proteinsand/or non-protein energy supply (particularly through fats) is generally associated withan increase in whole-body lipids. Increasing awareness exists of the effects of such highcaloric intake on the quality of fish products as human food, because the localization,quantitative importance and composition of body fat deposits may affect their dieteticvalue, organoleptic properties, transformation yield and storage stability. The ami of thisstudy is conducted to elucidate the effect of dietary carnitine on the growth performanceand body lipid distribution of silver perch.5. Improve the cellular immunity of eel (Anguilla japonica) after chitosan or β-glucaninduced.The purpose of this study is to define the activity of phagocytosis in macrophage afterJapanese eel ( Anguilla japonica) being induced by chitosan and glucan. The phagocytosiscapability will be examined, on cultured plate, after macrophages of experimental groupare challenged by bacteria in vitro.- 11 -*1111021999732* 1111021999732 2005/03/17 09:13:196. The research and development of high quality feeds on tiger shrimp broodstock.This project will acquire the rearing tiger shrimp broodstock situation in the mainproduction area that for the relative government to make policy consultation and someinstructional decision.Those will know the the tiger shrimp broodstock administrationstyle, broodstock fecundity, shrimp health, survival rate in the rearing station in order toestablish the production mode of tiger shrimp broodstock. We research the high qualityand low pollution of artificial feed for improving shrimp health, higher maturation,survival rate and fecundity of the tiger shrimp. Those will decrease the culture cost andthe tiger shrimp culture enterprise will be in beneficial administration forever.7. Studies on the superior quality of grouper.The present study was designed to determined dietary requirements of grouper foressential fatty acids with a goal to differentiate the fatty acids metabolism. Juvenilegrouper were reared on semipurified diets for 12 wks. Four experimental diets wereformulated to contained 10% fish oil, safflower oil, soybean oil or peanut oil.
