Wild-training method for improving anti-predation capability of released juvenile fish

The invention provides a wild-training method for improving the anti-predation capability of a released juvenile fish. The wild-training method is a method of predator fish material-object chasing. According to the predator fish material-object chasing method, a fishing line or a fishhook penetrates through the gill cover of a predator fish so that the predator fish is fastened on a handle lever and the fishing line is dragged when the predator fish is trained, so that the predator fish is made to chase the juvenile fish. When the predator fish approaches to the juvenile fish, the fishhook stabs the juvenile fish, so that the juvenile fish escapes rapidly. According to a model triggered scaring method, an electric mechanical arm is installed on one side of a juvenile fish culture pond, a predator fish plastic model is installed at one end of the electric mechanical arm, the electric mechanical arm is connected with a video monitoring system and receives signal feedback, and the video monitoring system forms a monitoring range which is 1m width and 1m long. When the juvenile fish enters the monitoring range, the electric mechanical arm receives a triggering signal and the plastic model suddenly stretched out, and therefore the approaching juvenile fish is scared and escape rapidly.
