本研究通过视频模型观察，探讨真鲷能否学习摄食区和回避区。在实验1中，45毫米的标准长度（SL）的鱼进行了培训，以了解一个饲养区在一个坦克。在实验2中，114毫米SL青少年接受训练，以避免移动到一个庇护所的手网。在每个实验中建立三种处理：（i）活体模型观察者：鱼观察相邻水箱中的真实的鱼的行为;（ii）视频模型观察者：鱼在监视器上观察同种的视频回放;和（iii）非观察对照。在两个实验中，对现场和视频模型观察者进行了10次观察试验。之后，来自所有处理的鱼通过饲料或回避训练来调节。在实验1中，在饲料学习过程中没有差异的治疗。相比之下，在实验2中，现场和视频模型观察员获得回避学习比对照组更快。结果表明，视频模型可以像现场模型一样有效地用于鱼类的观察学习。这项研究表明，视频播放可能是有用的抗捕食者训练的苗木股票增强。
The present study investigated whether red sea breamPagrus majorcould learn about feeding and avoidance area through video model observation. In Experiment 1, 45-mm standard length (SL) fish were trained to learn about a feeding area in a tank. In Experiment 2, 114-mm SL juveniles were trained to avoid a hand net by moving into a shelter. Three treatments were established in each experiment: (i) live model observer: fish observed the behavior of a real fish in an adjacent tank; (ii) video model observer: fish observed video playback of a conspecific on a monitor; and (iii) non-observing control. Ten observational trials were performed in both experiments for the live and video model observer. Afterwards, fish from all treatments were conditioned by feed or avoidance training. In Experiment 1, there was no difference in the feed learning process among treatments. In contrast, in Experiment 2, live and video model observers acquired avoidance learning more quickly than control. The result indicates that the video model can be as efficient as the live model for observational learning in fish. This study suggests that video playback may be useful for anti-predator training of seedlings for stock enhancement.
