	<span style=\"font-size:14px;\">本文用添加不同剂量海藻发酵液的饲料投喂4月龄和5月龄的幼鲍，比较30天内幼鲍生长、饲料转化率和死亡率的差异，结果表明：在4月龄幼鲍实验组，0.25%的海藻发酵液添加组生长最优，其壳长日增长率(183.44 ± 6.47 μm？d<sup>？1</sup>)、壳宽日增长量(124.96 ± 5.27 μm？d<sup>？1</sup>)均显著高于其他处理组(P &lt; 0.05)，个重日增长率(24.06 ± 0.97 mg？d<sup>？1</sup>)高于其他处理组(差异不显著)，死亡率(1.22% ± 0.75%)低于其他处理组(差异不显著)，1.0%海藻发酵液添加组饲料转化率高于其他处理组(差异不显著)；在5月龄幼鲍实验组，1.0%添加组的壳长日增长率(162.71 ± 5.79 μm？d<sup>？1</sup>)、壳宽日增长量(104.18 ± 4.28 μm？d<sup>？1</sup>)均显著高于其他处理组(P &lt; 0.05)，个重日增长率(27.91 ± 2.35 mg？d<sup>？1</sup>)高于其他处理组(差异不显著)，死亡率(1.15% ± 0.93%)低于其他处理组(差异不显著)，对照组饲料转化率高于其他处理组(差异不显著)。0.25%~1%的海藻发酵液添加能够促进4~5月龄幼鲍的生长。<br />
In this paper, 4-month-old and 5-month-old juvenile <i>Haliotis discus hannai</i> were fed with different doses of seaweed fermentation broth, and the differences in growth, feed conversion rate and mortality of young abalones were compared within 30 days. The results showed that in the 4-month-old young abalone experimental group, the 0.5% seaweed fermentation broth added group grown best. The daily growth of the shell (183.44 ± 6.47 μm？d<sup>？1</sup>) and the daily growth of the shell width (124.96 ± 5.27 μm？d<sup>？1</sup>) were significantly higher than those of the other treatment groups. The daily growth of weight (24.06 ± 0.97 mg？d<sup>？1</sup>) was higher than that of other treatment groups (the difference was not significant), and the mortality rate (1.22% ± 0.75%) was lower than that of other treatment groups (the difference was not significant). The feed conversion rate of the 1.0% seaweed fermentation broth supplement group was higher than that of other treatment groups (the difference was not significant). In the 5-month-old young abalone experimental group, the daily increase in shell length (162.71 ± 5.79 μm？d<sup>？1</sup>) and the daily increase in shell width (104.18 ± 4.28 μm？d<sup>？1</sup>) in the 1.0% supplementation group were significantly higher than those in the other groups. In the treatment group, the daily growth of weight (27.91 ± 2.35 mg？d<sup>？1</sup>) was higher than that in other treatment groups (the difference was not significant), and the mortality rate (1.15% ± 0.93%) was lower than in other treatment groups (the difference was not significant). The feed conversion rate of the control group was higher than the other treatment groups (the difference was not significant). The addition of 0.25% - 1% seaweed fermentation broth can promote the growth of 4-month-old and 5-month-old abalones.</span>
