| 摘 要： | 为评估短角异剑水蚤(Apocyclops royi)作为海水鱼类仔稚鱼的饵料价值和投喂效果,比较分析了其与卤虫无节幼体(Artemia nauplii)的脂肪酸组成及2种生物饵料对克氏双锯鱼(Amphiprion clarkii)稚鱼存活、生长和脂肪酸组成的影响。结果显示,短角异剑水蚤DHA、EPA和ARA含量分别达21.185%、11.088%和3.250%,海水仔稚鱼必需脂肪酸(EFA)总含量高达37.417%,均显著高于卤虫无节幼体。投喂短角异剑水蚤的克氏双锯鱼稚鱼(5~20 d)成活率(80.71%±8.23%)与投喂卤虫无节幼体组(76.30%±7.00%)差异不显著;稚鱼体长(7.75 mm±1.18 mm)、体重(0.0163 g±0.0080 g)和体长特定生长率(3.46%±0.75%)均显著高于卤虫无节幼体投喂组;稚鱼体内DHA(21.843%)、EPA(6.914%)和ARA(2.725%)含量也均显著高于后者。研究表明,短角异剑水蚤适于作为海水鱼类仔稚鱼的生物饵料,在水产养殖中具有广阔的应用前景。

Study of the survival, growth rate and fatty acid composition of juvenile of Amphiprion clarkii fed with Apocyclops royi |

| Abstract: | To evaluate the nutritive value and feeding effects of Apocyclops royi for marine fish larvae, comparative analysis of fatty acid composition of A. royi with Artemia nauplii was carried out. The results showed that the contents of DHA, EPA, ARA and essential fatty acid (EFA) in A. royi were 21.185%, 11.088%, 3.250% and 37.417% respectively, which were significantly higher than those in Artemia nauplii. Both of A. royi and Artemia nauplii were chosen to raise the juvenile of Amphiprion clarkii from 5 to 20 days post hatch and then the survival, growth rate and fatty acid composition of the juvenile were assessed. The results showed that the juveniles fed with copepods had significantly higher growth rate than those fed with Artemia nauplii (P< 0.01), while the difference in survival rate was not significant (P>0.05). The contents of the three EFAs (DHA, EPA and ARA) in juvenile of A. clarkii fed with A. royi were 21.843%, 6.914% and 2.725% respectively, which were significantly higher than those in juvenile of A. clarkii fed with Artemia nauplii (P<0.01). This paper proposed that A. royi was suitable as living feed organism of marine fish larvae, and had wide application prospect in aquaculture. |
