| 摘要: |
| 蜕壳后新甲壳完全硬化之前是中国龙虾(Panulirus stimpsoni)个体蜕壳生长过程的延续,对中国龙虾正常快速生长具有重要意义。环境因子、营养条件对中国龙虾的蜕壳与生长具有显著影响。24-27℃是中国龙虾蜕壳生长的适温范围;盐度24-32适宜中国龙虾生长,最适生长盐度是28;在6种试验饵料中翡翠贻贝饲养中国龙虾效果最好,其次是杂虾、杂蟹、牡蛎,投喂杂鱼的中国龙虾蜕壳增长率和阶段生长率都很低;龙虾饲料中添加蜕壳素能够縮短蜕壳周期,实现蜕壳率和蜕壳增长率的同步增长。摘除眼柄也能促进中国龙虾的蜕壳与生长,电刺激等外源刺激则只能促进蜕壳,而不能加速中国龙虾的生长,甚至可能产生负面影响。中国龙虾生长存在种内性别间的差异,同等条件下雄性个体的蜕壳增长率高于雌性个体。 |

| The growing characteristics and accelerating ways for growth of the spiny lobster, Panulirus stimpsoni |

| Abstract: |
| The Chinese spiny lobster, Panulirus stimpsoni, is the most important spiny lobster species, which gregariously inhabits in China seas. The same as other decapoda, the lobster grows via molt,however, it has a long time for growth before the newly carapace gets hard completely, which was significant for the better growth of lobster. The growth rates of the lobster kept different between the male and female ones, and the female lobster commonly grew less than the male ones in the same condition. The environmental factors, such as water temperature, salinity et al., and the nutrition qualification as varieties of diet were all the important factors affected the growth of the lobster. At the optimal condition,water temperature 27℃ and the salinity 28, the intermolt period of the lobster can probably be less than 54 days and molt growth rate up to 29.29%. The lobster grew well with taking in the food of mussels, oysters et al.. And the lobster treated with extirpated eyestalk grew better than that of free treatment,whereas impulse activation can only contribute to molt not to growth of the lobster. |
