用3种营养强化剂强化的轮虫和卤虫无节幼体投喂牙鲆仔鱼,研究牙鲆仔鱼的生长、成活、体脂肪酸的组成。结果表明:用强化的轮虫和卤虫无节幼体投喂牙鲆仔鱼,成活率、增重均显著高于对照组(p<0 01),其中V号强化剂的效果最好,成活率为29 34%,比对照组提高100%;增重倍数为217 90,比对照组提高68 61%;这是由于V号强化剂强化的卤虫无节幼体体内含有较多的AA的缘故,饵料中AA含量的提高,可以提高牙鲆仔鱼的成活率、促进其生长。牙鲆摄食强化过的轮虫、卤虫无节幼体后,其EPA、DHA、n-3HUFA、PUFA的含量随着饵料中含量的升高而升高,这也是牙鲆仔鱼生长速度和成活率提高的重要因素之一。
The growth, survival and body fat composition of larvae of Paralichthys olivaceus were studied using three kinds of fortification-enhanced rotifer and Artemia nauplii. The results showed that the survival rate and weight gain of juvenile Paralichthys olivaceus fed with enhanced rotifer and Artemia nauplii were significantly higher than those of the control group (p <0.01). The effect of the number V enhancer was the best, and the survival rate 29 34% higher than the control group 100%; weight gain ratio of 217 90, 68 61% higher than the control group; This is due to V enhancer Artemia nauplii body contains more AA sake, Increasing the AA content in bait can increase the survival rate of larvae larvae and promote their growth. The contents of EPA, DHA, n-3HUFA and PUFA in the Japanese flounder increased with the increase of dietary levels after feeding fortified rotifers and Artemia nauplii, which is also the growth rate and survival rate One of the important factors to improve.
