摘要
利用卵巢未发育的海捕日本对虾Penaeusjaponicus,采用综合措施,进行切除眼柄前、后两个阶段培育,促进卵巢发育和成熟。结果:切除眼柄前分别在t=15.0—18℃和20.0─23.0℃经17d左右的培育,卵巢发育率为62%—65%;切除眼柄后在t=25.0—25.5℃经4—5d的培育,亲虾成批成熟和产卵,成熟率为96%。先后两批共育出了3020万尾苗种。
enaeus japonicus from sea are used in this experiment. Ovarians of these Penaeus japonicus are not developed yet. We employed comprehensive measures and carried on culture before and after eyestalk removal to promote the ovarian development and matulation. Ovarian development rate before eyestalk removal was 62%-65%,while we used t=15. 0-18.2℃ and 20. 0-23.0℃ and cultured 17 days approximately. Ovarian maturation rate after eyestalk removal was 96%, while we used t=25. 0-25. 5℃ and cultured 4-5 days. A great amount of broodstock was matured and spawn. This experiment met the requirements of commercial production. We raised 30 200 thousands survivors through two batches.
