摘　　要：脊尾白虾是我国重要的海水养殖种类,目前主要依靠投喂传统饵料(冰鱼和小麦粉混合物)进行养殖,采用配合饲料喂养是发展趋势,在池塘养殖条件下比较投喂配合饲料和传统饵料对脊尾白虾生长、养殖性能、生理代谢和生化组成的影响。结果显示:配合饲料组的饵料系数显著低于传统饵料组(P<0.05);配合饲料组肝胰腺中的谷丙转氨酶和总超氧化物歧化酶的活力和尿素氮的含量都显著高于传统饵料组(P<0.05);配合饲料组肌肉中的水分含量显著低于传统饵料组,但灰分含量显著高于传统饵料组(P<0.05);配合饲料组肌肉中的单不饱和脂肪酸(MUFA)、多不饱和脂肪酸(PUFA)和n-6多不饱和脂肪酸(n-6PUFA)的含量显著高于传统饵料组;配合饲料组肌肉中的必须氨基酸(EAA)和总氨基酸(TAA)的含量均显著高于传统饵料组(P<0.05)。Ridgetail white prawns(Exopalaemon carinicauda)is an important marine aquaculture species in China.At present,E.carinicauda is mainly fed with traditional diets(trash fish and wheat meal mixture)during the whole culture process.In this study,we investigated the effect of two feeding modes(formulated diets,traditional diets)on the growth culture performance,physiological metabolism and biochemical composition of pond-reared E.carinicauda.The result showed that the feed conversion ratio(FCR)of E.carinicauda fed with formulated diets was significantly lower than that with the traditional diets treatment(P<0.05).The activity of glutamate-pyruvic transaminase(GPT)and superoxide dismutase(SOD)and the contents of blood urea nitrogen(BUN)in hepatopancreas of formulated diets treatment were significantly higher than those in traditional diets treatment(P<0.05).The contents of moisture in muscle of formulated diets treatment were lower than those in traditional diets treatment,while the contents of ash in muscle were higher than those in traditional diets treatment(P<0.05).The contents of monounsaturated fatty acid(MUFA),polyunsaturated fatty acid(PUFA)and n-6 polyunsaturated fatty acid(n-6PUFA)in hepatopancreas of formulated diets treatment were significantly higher than those of the traditional diets treatment(P<0.05).The contents of essential amino acids(EAA)and total amino acids(TAA)in muscle of formulated diets treatment were significantly higher than those of the traditional diets treatment.
