１９９１－１９９３年在中国青岛市对真鲷苗种生产技术进行了连续三年的开发研究，通过改善亲鱼培育及采卵技术、提高轮虫连续培养及稳定供应技术、提高仔鱼开鳔率、加强饵料的营养强化、设置环流及水面集污器等技术措施、改进和完善了真鲷苗种生产工艺。利用 １７５ｍ３培育水体，三年中共育出真鲷苗种 ２９１． ６万尾，各年度的苗种生产量分别为 ５１．８万尾、１１６．４万尾、１２３．４万尾；培苗成活率分别为２５．６％、３２．８％、６２．５％；平均单位水体出苗量分别为２９６０尾／ｍ３、６６５１尾／ｍ３、９８７２尾／ｍ３。在国内首次实现苗种生产三年连续成功，并连续突破百万尾大关。同时试验证明利用对虾育苗池进行真纲苗种生产是可行的。
In 1991-1993, the research and development of seabream seed production technology was conducted in Qingdao, China for three years in a row. By improving broodstock breeding and ovum harvesting techniques, continuous rotifer culture and stable supply techniques were improved, Nutrition enhancement of bait, setting circulation and surface water trap and other technical measures to improve and improve the production technology of seabream seedlings. The use of 175m3 to cultivate water body, three years raised a total of 291 seabream seedlings. 60,000, respectively. The annual seed production was 518,000, 1,164,000 and 1,234,000, respectively. The survival rates of the seedlings were 25.6%, 32.8% and 62.5, respectively %; The average unit of water emergence were 2960 / m3,6651 / m3, 9872 / m3. In the country for the first time to achieve three consecutive years of seed production success, and a continuous breakthrough million mark. At the same time, experiments show that it is feasible to use shrimp nursery ponds to carry out the seed production of Shinsengumi.
