通过室内和室外养殖试验，探讨饲料中添加复合芽孢杆菌（纳豆芽孢杆菌＋枯草芽孢杆菌）对三疣梭子蟹（PortunustrituberculatusMiers）生长性能、消化酶活性及养殖效益的影响．试验结果表明：添加1‰（T1）和21‰（T2）的复合芽孢杆菌饲料组幼蟹的蜕壳率、成活率和增重率均高于对照组（T0）；摄食率随着芽孢杆菌浓度上升而呈现下降趋势；T1和T2组分别降低幼蟹饲料系数为15．38％和18．80％．芽孢杆菌添加显著影响胃、胰蛋白酶以及肝胰腺脂肪酶活性，但淀粉酶活性没有明显变化．室外池塘养殖结果表明：商品饲料中添加2％。复合芽孢杆菌的饲料组（D2）平均产量最高，比只投喂商品饲料组（D1）增产14．4％；D2组起捕时蟹平均壳宽比D1组大3．4％．饲料系数方面，D1组和D2组差异不大．认为三疣梭子蟹养殖饲料中添加2‰的芽孢杆菌具有较好的效果．

The study is conducted to investigate the effects of dietary supplementation with compound bacillus （Bacillus subtilis Natto and Bacillus subtilis Cohn） on growth condition, digestive enzyme activity and cultivation efficiency in Portunus trituberculatus （Miers, 1876）. The results from the indoor feed trial indicate that the colonization rate, survival rate and weight gain in 1%o （T1） and 2%0 （T2） bacillus supplementation groups are higher than that of the control group. Feed intake presents a decline trend with dietary bacillus level. Feed conversion rate in T1 and T2 are reduced by 15.38% and 18.80% when compared with the control diet, respectively. Dietary compound bacillus shows no significant effect on amylase activity among the groups, but it influences the other digestive enzyme activities. The highest average product in the outdoor pond feeding trail is observed in P. trituberculatus fed with commercial feed with 2‰ compound bacillus （D2）. The final breadth in D2 group is found to be 3.3% higher than that of in D 1 （commercial feed） group. Feed conversion rates are found very similar in D1 and D2 groups. It suggests that 2‰ compound bacillus supplemented in diet is suitable for P. trituberculatus.
