碩士 / 國立臺灣海洋大學 / 水產養殖學系 / 105 / Three feeding trials were conducted to examine the effect of dietary supplemented with shrimp hydrolysate powder (SHP), tilapia protein hydrolysate (TH) and soy protein hydrolysate (SPH) replace fish meal protein on the growth performance and body composition of the Pacific white shrimp Litopenaeus vannamei. All experimental diets were formulated to content isonitrogenous (31% crude protein) and isolipidic (9% crude lipid).
In the first experiment, six experimental diets were formulated to supplement with 0%, 1%, 2%, 3%, 4% and 5% of SHP. Ten 4.23g white shrimp were randomly distributed to six treatment groups in triplicate. The shrimp were fed ad libitum three times a day for nine weeks. Termination of the experiment, the weight gain and SGR of shrimp fed diets containing 2-5 % SHP had no significant different from those of shrimp fed control diet. Shrimp fed diets containing 0%, 4% and 5% SHP had significantly higher weight gain than those fed diet containing 1% SHP. Shrimp fed a diet with containing 5% SHP had the best growth performance. The survival of shrimp fed treatment diets range from 93% to 97%.
In the second experiment, six experimental diets were formulated to supplement with 0%, 1%, 2%, 3%, 4% and 5% of TH. Twenty 0.028g white shrimp were randomly distributed to six treatment groups in triplicate. The shrimp were fed ad libitum three times a day for six weeks. The WG and SGR of shrimp fed diets containing 1-3% TH had no significantly different from those of shrimp fed control diet. Shrimp fed diets containing 4% and 5% TH had significantly higher weight gain than those fed diet containing 0% TH. Shrimp fed a diet with containing 5% TH had the best growth performance. The survival of shrimp fed treatment diets range from 82% to 93%.
In the third experiment, six experimental diets were formulated replace fish meal protein with 0%, 5%, 10%, 15%, 20% and 25% of SPH. Twenty 0.028g white shrimp were randomly distributed to six treatment groups in triplicate. The shrimp were fed ad libitum three times a day for six weeks. The WG and SGR of shrimp fed diets containing 5%, 10%, 15% and 20% SPH were not significantly different from those of shrimp fed control diet. Shrimp fed diets containing 0%, 5%, 10%, 15% and 20% SPH had significantly higher weight gain than those fed diet containing 25% SPH. Shrimp fed a diet with containing 5% SPH had the best growth performance. The survival of shrimp fed treatment diets range from 78% to 93%.
