为探索漠斑牙鲆的苗种培育技术 ,分别于 2 0 0 3年和 2 0 0 4年从美国引进漠斑牙鲆的初孵仔鱼进行鱼苗培育试验和淡化试验。试验获得了成功。 2 0 0 3年引进初孵仔鱼 4 .0万尾 ,培育出体长 4 5cm的鱼苗 2 2 5 0尾 ,鱼苗培育成活率为 5 .6 % ,其中前期和后期的培育成活率分别为 9.0 %和 6 2 .5 %。 2 0 0 4年引进初孵仔鱼 4 .5万尾 ,经培育共获得体长 4 5cm的鱼苗 2 830尾 ,培育成活率为 6 .3% ,其中前期和后期的培育成活率分别为 11.8%和 6 3.6 %。经过逐步淡化的鱼苗在纯淡水中生长良好。
In order to explore the technique of seed culture of Paralichthys olivaceus, the newly hatched larvae of Japanese flounder (Paralichthys olivaceus) were introduced into the fry culture experiment and desalination test in 2003 and 2004, respectively. The experiment was successful. In 2004, 40,000 newly hatched larvae were introduced, 22,500 fry fish with a length of 45 cm were bred and the survival rate of fry breeding was 5.6%, of which the pre-and post-breeding survival rates were 9.0 % And 62.5%. In 2004, 45,500 newly hatched larvae were introduced. After breeding, 2 830 fry with a body length of 45 cm were obtained, with a breeding survival rate of 6.3%. The breeding survival rates in the early and late stages were 11.8% And 3.6%. After gradually desalination fry grow well in pure fresh water.
