Abstract: The artificial proliferation and release of hatchery fish has not achieved expected results, primarily due to the low survival rate of the fish after released into natural environment. The life skill trainings for the hatchery fish before its release may have active effects on the improvement of the survival rate of post-release. This paper analyzed the reasons for the low survival rate of fish post-release, and pointed out that foraging and anti-predation capability was one of the key factors affecting the survival rate of fish post-release. The key factors affecting the foraging and anti-predation capability, including prey and predator recognition, social learning experience, environmental complexity, and fish swimming ability were discussed, and the innovative training techniques leading to a higher fish postrelease survival rate were suggested.
