摘要:

］分别使用n-3HUFA强化剂A（A1:0.05 g/L;A2:0.15 g/L;A3:0.45 g/L）、强化剂B（B1：0.05 mL/L；B2:0.15 mL/L；B3:0.45mL/L）和海水小球藻对褶皱臂尾轮虫（Brachionus plicatilis）进行营养强化后投喂大黄鱼仔鱼（3~21日龄），测定分析各强化组轮虫的脂肪酸相对含量与仔鱼的生长和存活率之间的相互关系，并与对照组（酵母轮虫）进行比较.结果显示：1）用强化剂A和海水小球藻强化的轮虫，其n-3HUFA含量明显高于对照组和强化剂B组，各组仔鱼的存活率从高到低顺序为：A2组（22.2 %）>小球藻组（16.7 %）>A1组（13.9 %）>A3组（13.8 %）>B1组(2.1 %)>B2组(1.8 %)>B3组(0.7 %)>对照组（0.5 %）；2）强化剂A各水平强化组和海水小球藻组仔鱼生长优于强化剂B各水平强化组和对照组；3）本实验条件下，在强化水体中强化剂A适宜的强化剂量为0.15 g/L

Abstract:

This study was conducted to investigate the effects of the rotifers Brachionus plicatilis enriched with three different kinds of lipid fortifier on growth and survival of larval large yellow crocker，Pseudosciaena crocea．Rotifers were enriched with different levels of A(A1：0.05 g/L; A2:0.15 g/L；A3：0.45 g/L) and B(B1：0.05 mL/L；B2：0.15 mL/L；B3：0.45 mL/L）lipid fortifier as well as marine chlorella before fed to large yellow crocker larvae, respectively.The experimental results showed that the rotifers enriched with A fortifier and marine chlorella had higher n-3HUFA content than those enriched with B fortifier and yeast.The large yellow crocker larvae fed with the rotifer enriched with A and marine chlorella had higher survival rate and growth rate than those fed with those enriched with B and without enrichment.The highest survival rate（22.2 %）and the better growth of larval yellow crocker were obtained in the experimental group fed with rotifers enriched with A2 (0.15 g/L).The lowest survival rate was recorded in control group (without enrichment).These results suggested that rotifers enriched with A fortifie were better than B fortifier in terms of n-3 HUFA nutrition for large yellow crocker larvae.
