| 摘 要： | 以黑鲷Sparus macrocephalus作为试验对象，采用音响驯化技术，每天配合投饵定时放声集鱼。结果表明，驯化7d后，黑鲷对声音产生了反应，并呈正趋声性。试验初期，黑鲷的摄食时间为10～12min，驯化结束时其摄食时间缩短到2～3min。试验期间，定期测量鱼的体长和体重，得出鱼的体长、体重与摄食量的关系曲线图及关系方程，从而确定在黑鲷的不同生长阶段(60～100g)，其日摄食量为4．38～6．47g／尾。

| Abstract: | The feed given were immediately eaten by black bream Sparus macrocephalus schooled by acoustic behavior control, which increases the feed efficiency and deceases feed remains. The fish positively responsed to the sound after having been trained for 7 days. The feeding period desreased from 10-12 min. at the beginning of the experiment to 2-3 min at the end of the experiment. The curve and equation between the amount of feed fed by the fish and body weight (body length) were given in various growing periods to guide the feeding rate in cage culture. It was found that the fish with 60-100 g in body weight consummed 4.38-6.47 g/ind. daily. |
