不同饵料及添加剂对中国对虾幼体的影响
THE EFFECTS OF DIFFERENT FOODS AND ADDITIVES ON THE HEALTH OF LARVAE OF Penaeus chinensis
【摘要】 在连续两年春季中国对虾(Penaeuschinensis)育苗期间 ,采用几种不同的饵料———人工饵料为主、活饵料和两种强化饵料分别培育中国对虾幼体 ,以存活率、体长、体重、抗感染力和缺氧耐受力等指标检验育苗效果。结果表明 ,人工饵料为主的喂养方式各项指标均显著劣于活饵料 ;强化与未强化的活饵料效果相近 ;强化的人工饵料在体长和耐缺氧方面显著优于人工饵料 ,存活率略低于后者 ,增重和抗感染方面与后者相近。
【Abstract】 Several kinds of nutrition method, artificial food, linving food and strengthened food, were adapted to culture larvae of Penaeus chinensis during the springs of 1995 and 1996, and then examine the effects by the survival rate, biological length, net weigh, ability to disease-resistant and resistance to low oxygen content. The results indicated that every index of larvae fed on artificial food was obviously worse than that fed on living food. The artificial feed method in experiment was wide used by many larvae culture farms at present, so the results proved that larvae culture works had great potentialities in food improvement. The effect of strengthened living food was similar to that of living food. The biological length and resistance to low oxygen content of strengthened artificial food were better than that of artificial food , the survival rate was slightly lower than the later, and the net weight and ability of disease-resistance were similar to the later. The artificial feed method in experiment was wide used by many larvae culture farms at present, so the results proved that works had great potentialities in food improvement. The effect of strengthened living food was similar to that of living food. So the results proved that works and great potentialities in food improvement for larvae culture. Strengthened artificial living food by adding vitamin C and fish oil was attemption for improving food quality and win initial success, but it still need us explore further.
