| 摘要: |
| 对云斑尖塘鳢(Oxyeleotris marmoratus(Bleeker))人工育苗技术进行了初步的研究,利用燃油热水炉加温进行亲鱼越冬,采取人工辅助控温、保温的方法,配合其生态条件的调控和投喂优质饲料,培育亲鱼成熟并能自然产卵,使用人工饵料、代用饵料、生物饵料等混合饵料互相搭配组合,经过2个月左右的培育鱼苗全长达3 cm左右。亲鱼具多次产卵习性,观察到一年当中最多产卵4次。利用外源激素催产率达到95.0%,自然产卵的受精率和孵化率均高于人工催产。 |

| Abstract: |
| The parent Oxyeleotris marmoratus(Bleeker) reached sexual maturity in the artificial control temperature to live through the winter. It was spawn that the fish could be fed in care culture including the conditions of high quality fodder and the main ecological factors control. The fertilized eggs incubated to fry and developed to 3 cm through two months' feeding live bait and artificial feed. The O. marmoratus(Bleeker) can spawn several times one year. The months' most ones were 4 times in the lab. The induced spawning rate was 95.0% using hormone. The nature fertilized rate was higher than that of artificial propagation. |
