人工调节卤虫体内n-3HUFA含量对黑鲷稚鱼生长、存活的影响

THE EFFECT OF THE ARTIFICIAL REGULATION OF n-3HUFA CONTENTS IN ARTEMIA ON GROWTH AND SURVIVAL IN BLACK SEABREAM LARVAE

海水仔稚鱼营养的研究,国外已有相当数量的报道,特别是脂类中n-3高度不饱和脂肪酸(n-3HUFA)的研究,已取得显著的成果(Izquierdo et al.,1989 a;Izquierdo et al.,1989 b;Watanabeetal.,1994)。但迄今为止。

The requirement for dietary n-3HUFA for growth and survival in black sea bream (Sparus macrocephalus) larvae was tested using Artemia with various levels of n-3 HUFA. Four treatments for Artemia differing in the relative content of their n-3 HUFA (32. 0,33. 0, 35. 1,36. 2mg/100mg TFA) were prepared by feeding them various oil emulsions.The results indicated that dietary n-3HUFA significantly influence fish n-3HUFA levels and are necessary for good growth and survival in black sea bream larvae. The optimal value of n-3 HUFA level in Artemia should be≥4. 273%(wet weight) for the best growth and survival in black sea bream.
