Abstract:
In order to rehabilitate the stock of Pseudosciaena crocea in Daiquyang sea area, we carried out a test on the release and proliferation of P.crocea during 2000~2009. We released 1 288.0104 artificially cultured fries including 62 680 tagged juveniles into Daiquyang; 1 432 fishes were recaptured2 months with an average recapture rate of 2.73%. Result shows that the release of the local P.crocea in Daiquyang sea areais feasible, and hanging scutcheon is suitable for the tagging and release. The released fish can not only survive and grow but also spawn and migrate. The release significantly restore the local P.croceastock in Zhoushan fishing ground and has created economic benefits.
