| Abstract: |
| A marine ranching program was initiated in Jiaozhou Bay in 1980. The data of investigation of multispecies resources and their ecological characteristic were comparatively analysed, and then the False Halibut was choson for ranching experiment. Data show that fish are distributer in the shallow water inside and outside Jiaozhou Bay all the year round, spawning from April to June, sexually maturing at 1-3 years of age, and feeding on benthic organisms (some small fish and crustacean). Though the fish have a high fecundity and rapid growth rate, their high death rate in its early developmental stage restricts the population abundance to a lower level. To improve the stock recruitment, a lot of cultured young fish were relased into a suitable area in Jiaozhou Bay, and more than 1% tagged fish were recaptured several month later or next year. |
