腐植酸发酵肽、枯草芽孢杆菌、嗜酸乳杆菌在海刺参与基围虾混养中的应用

Application Effects of Humic Acid Fermentation Peptide, Bacillus Subtilis and Lactobacillus Acidlophilus in Mixed Feeding of Sea Cucumber and Shrimp

将腐植酸发酵肽、枯草芽孢杆菌、嗜酸乳杆菌应用于海刺参、基围虾的养殖中,并对增产效果进行试验研究。海刺参与基围虾大面积混养试验结果表明:与对照组相比,海刺参增重率22.76%~28.49%,基围虾增重率12.18%~25.64%,净收益增加3480~4050元/亩。海刺参大面积养殖试验结果表明:与对照组相比,海刺参增重率45.02%、成活率提高6.67个百分点,饲料报酬率(FCR)降低0.498,净收益增加1040元/亩。基围虾大面积养殖试验结果表明:与对照组相比,基围虾增重率30.28%、成活率提高24.4个百分点,饲料报酬率(FCR)降低0.221,净收益增加250元/亩。可见,腐植酸发酵肽是一种创新型生物饲料添加剂,在水产养殖中具有广阔的应用前景。

The humic acid fermentation peptide,Bacillus Subtilis,Lactobacillus Acidophilus were used in the cultivation of sea cucumbers and shrimps,and the effect of yield increase was studied experimentaly.In the sea cucumber and shrimp large-area mixed feeding,the results showed that compared with the control group,the weight gain rate of sea cucumber increased 22.76%~28.49%,the weight gain rate of shrimps increased12.18%~25.64%,net income increased 3480~4050 yuan/667 m^2.In the sea cucumber large-area feeding,the results showed that compared with the control group,the weight gain rate of sea cucumber increased45.02%,the rate of survival increased 6.67 percentage points,feed conversion rate reduced 0.498,net income increased 1040 yuan/667 m^2.In the shrimp large-area feeding,the results showed that compared with the control group,the weight gain rate of shrimps increased 30.28%,the rate of survival increased 24.4 percentage points,feed conversion rate reduced 0.221,net income increased 250 yuan/667 m^2.In summary,humic acid fermentation peptide is an innovative biological feed additive,which has a broad prospect in aquaculture.
