摘要
为优化海上养鲍设施,特别是养鲍网箱结构,开展了40 d的皱纹盘鲍杂交鲍幼鲍(Haliotis discus hannai♀×Haliotis discus discuss♂)在0 Lx(暗光照)、0~500 Lx(弱光照)、0~6500 Lx(强光照)3组不同光照强度下的生长与活动试验。结果显示,壳长(4.86±0.17)cm、体重(15.08±1.07)g的幼鲍,壳长平均目增长和体重平均目增长分别为0.0141±0.003cm/d和0.0549±0.011g/d(暗光组)、0.0083±0.003cm/d和0.046±0.013g/d(弱光组)、0.007±0.001 cm/d和0.0284±0.016g/d(强光组),二者均与光照强度呈反比,且光照对鲍壳生长的影响大于对质量的影响。暗光照环境下,幼鲍活动时间提前30 min,活动时间增加0.5~1 h,且进食量大、进食速度快。研究表明,强光照能对鲍形成光压抑的生活环境,影响鲍的正常行为与生长。海上养鲍应根据鲍对光照刺激的反应,选择适宜的水层,并优化网箱和匍匐基结构。
The differentia of behavior and growth of juvenile hybrid Pacific Abalone cultured under different light intensity are reported in this paper based on the comparison experiments,which's light intensity are 0 Lx(dark intensity),0~500Lx(weak intensity),0~6500Lx(strong intensity),respectively.The result shows that the activity time,feeding speed,food-intake and the growth of the juvenile hybrid Pacific Abalone are strongly effected by the light intensity.For the size of 15.08 ±1.07 g.in weight and 4.86±0.17 cm in shell length,The daily growth of shell length were 0.007±0.001 cm/d in strong intensity,0.0083±0.003cm/d in weak intensity and0.0141±0.003cm/d in dark;and the average daily gain are 0.0284±0.016g/d in strong intensity,0.046±0.013g/d in weak intensity and 0.0549±0.011g/d in dark.The impact on the growth of shell is more outstanding that on the growth of weight.The daily feeding rates are:strong intensity is9.92%,weak intensity is 10.26%,dark is 11%;the feed conversion ratios are:strong intensity is1.75%,weak intensity is 2.68%,dark is 2.92%.The juvenile abalones living in the dark pond distributed more consistantly and were more active than the other two groups.They usually exercise and take food half an hour earlier than the other two groups.They also have the best appetite and eat fastest.Such result is consistent with the natural instincts of abalones that they like to live in dark environment and hide by day and come out by night.
