摘　　要：选取6种不同品牌斑节对虾商品饲料（D1、D2、D3、D4、D5和D6）进行60 d养殖试验,评价其对斑节对虾（Penaeus monodon）生长及水质的影响。D1、D5和D6的对虾增重率和特定生长率显著高于D2和D4（P〈0.05）;D5和D6的饲料系数显著低于D2和D4（P〈0.05）。D4和D5的蛋白质消化率显著高于D1~D3各饲料（P〈0.05）。第20天水体化学需氧量（COD）D1最低,显著低于D5和D6（P〈0.05）。第40天时D5和D6的COD显著低于D1~D4各饲料（P〈0.05）,D2的氨氮（NH＋4-N）最低,显著低于D4~D6各饲料,总氮（TN）、总磷（TP）分别在D4、D6最低。第60天时D1和D2的NH＋4-N显著低于其他各饲料（P〈0.05）,D5和D6的TN显著低于D1~D4各饲料（P〈0.05）,而TP在D2最低,显著低于D1和D4（P〈0.05）。氮（N）排放率在D1和D6显著低于其余4种饲料（P〈0.05）,磷（P）排放率则D1最低。投喂D1、D5和D6能够使对虾获得较优生长性能,且对水体污染最小。To investigate the effects of different brands of commercial diets（D1,D2,D3,D4,D5 and D6） on the growth performance of black tiger shrimp（Penaeus monodon） and water quality,we fed the shrimps [average initial wet weight（2.82±0.02） g] with 6 diets for 60 d.The results show that the weight gain and special growth rate of shrimps fed with D1,D5 and D6 are significantly higher than those with D2 and D4（P0.05）,and the feed conversion ratios of shrimps fed with D5 and D6 are significantly lower than those with D2 and D4（P0.05）.The apparent protein digestibility of shrimps fed with D4 and D5 is much higher than those with D1~D3（P0.05）.At 20thday,the chemical oxygen demand（COD） with D1 treatment is the lowest and significantly lower than that with D5 and D6（P0.05）.At 40thday,the COD with D5 and D6 treatments are significantly lower than that with D1~D4 treatments（P0.05）.The NH4＋-N with D2 treatment is the lowest and significantly lower than that with D4~D6 treatments（P0.05）,and the total nitrogen（TN） and total phosphorus（TP） are the lowest with D4 and D6 treatments.At 60thday,the NH4＋-N with D1 treatment is the lowest and significantly lower than that with the other treatments except D2 treatment（P0.05）,and the TN with D5 and D6 treatments are significantly lower than that with D1~D4 treatments（P0.05）,but the TP with D2 treatment is the lowest and significantly lower than that with D1 and D4 treatments（P0.05）.The excretion rates of nitrogen with D1 and D6 treatments are the lowest and significantly lower than that with the other diet treatments（P0.05）.The minimum excretion rate of phosphorus is with D1 treatment.In conclusion,the shrimps fed with D1,D5 and D6 perform better in growth,and D1,D5 and D6 diets have minimal pollution to the water.
