| 摘 要： | 我们自1980年6月开始执行胶州湾水域生产农牧化研究课题任务以来,通过水域环境和生产力,以及渔业资源开发等项周年性和多年性调查,查明牙鲆在胶州湾水域资源结构中占有重要地位,且其体大味美,深受群众喜爱,因而选为拟增殖对象;对其资源增殖的生态学基础和种苗放流增殖技术方法等进行了专题研究。

STUDIES ON THE ECOLOGICAL BASIS OF RESOURCES MULTIPLICATIONAND STOCKING EXPERIMENT ON THE FALSE HALIBUT, PARALICHTHYS OLIVACEUS IN JIAOZHOU BAY |
| |
| 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. |
