摘    要:在实验室内营造半精养、精养养殖模式,研究不同养殖模式下底质类型(未添加底质、水泥底、全沙底、沙泥底和砂砾底)对中国明对虾(Fenneropenaeus chinensis)存活、生长及行为特征的影响.结果表明,半精养模式下,中国明对虾的存活率和蜕皮频率在各底质处理组间均无显著差异(P>0.05);而精养模式中未添加底质处理组实验虾的存活率和蜕皮频率最低,沙泥底处理组存活率和蜕皮频率最高,分别达到100%和12.9%/d.两种养殖模式下,底质类型对中国明对虾的特定生长率(SGR)均有显著影响(p<0.05),其中半精养模式沙泥底处理组实验虾的SGR最高,是未添加底质处理组的1.39倍;而精养模式未添加底质处理组的SGR最高,达到1.94%/d,但其与全沙底和沙泥底处理组无显著差异(P>0.05).底质类型对实验虾的行为特征亦有显著影响(P<0.05),半精养模式沙泥底处理组实验虾的寻(摄)食虾比率和运动率在投喂饵料前后均最高,而攻击频率在投喂饵料前于全沙底处理组中最高,投喂饵料后则在未添加底质处理组中最高,达到4.5次/(ind.h),但其与沙泥底和砂砾底处理组无显著差异(P>0.05);精养模式下,投喂饵料前全沙底处理组实验虾的寻食虾比率和攻击频率最高,而运动率在各处理组之间无显著差异(P>0.05),投喂饵料后实验虾的摄食虾比率在未添加底质处理组中最高,而在砂砾底处理组中最低,运动率和攻击频率则在沙泥底处理组中最高.综合分析表明,底质的添加有利于提高中国明对虾的生长和存活,且底质添加后实验虾能够根据不同底质环境进行行为的调节与整合.在本研究的4种底质类型中,中国明对虾更偏好于泥含量为30%的沙泥底质.

Abstract:

  We evaluated the effects of substrate type no substrate (control), concrete, sand, sand and mud, and gravel] on survival, growth, and behavior of Fenneropenaeus chinensis under laboratory conditions in a semi-intensive culture mode (SICM) and intensive culture mode (ICM). In the SICM, substrate type had no effect on survival (S) and molting frequency (MF) (P>0.05), though S and MF were lowest in the control and highest in the sand and mud substrate treatment (100% and 12.9 %/d, respectively) in the ICM. Substrate type significantly affected the specific growth rate (SGR) of F. chinensis reared in SICM and ICM (P<0.05). In the SICM, the SGR was highest in the sand and mud substrate treatment, and was 1.39 times higher than the SGR in the control. In the ICM, the SGR (1.94 %/d) was highest in the control, but there was no significant difference between the control, sand, and sand and mud substrate treatments (P>0.05). Substrate type had a significant effect on the behavior of F. chinensis (P<0.05). In the SICM, the feeding ratio (FR) and locomotion rate (LR) were all highest in the sand and mud substrate treatment before and after feeding, however, attacking frequency (AF) was highest in the sand substrate treatment before feeding and in the control treatment after feeding, peaking at 4.53 times/(shrimp?h−1). There was no significant difference in AF between the control, sand and mud substrate, and gravel substrate treatments (P>0.05). In the ICM, the FR and AF were highest in the sand substrate treatment before feeding and there was no difference in LR among the substrate treatment groups (P>0.05). The FR was highest in the control and lowest in the gravel substrate treatment after feeding. LR and AF were highest in the sand and mud substrate treatment. Our results suggest that the addition of substrate enhanced the growth and survival of F. chinensis in culture. F. chinensis exhibited behavioral differences when reared over different substrate types and preferred the sand and mud substrate.
