摘　　要：为有效增殖糙海参资源,2014年6月—2015年5月,以采自海南陵水沿海的天然糙海参为亲参,通过探索糙海参亲参运输、培育、诱导精卵排放以及幼体和稚幼参培育等技术,建立糙海参苗种规模化繁育关键技术体系。试验结果显示,采用薄膜袋充氧干运法运输糙海参,亲参成活率可达99.8%;亲参培育成活率达97.1%以上;采用阴干与流水相结合诱导亲参排放精卵,成功率达93.3%。以培育的亲参进行了12批次初耳幼体和稚幼苗培育试验,共放养初耳幼体5474万个,培育出体长1.0~5.5 cm幼参445.9万头,初耳幼体培育总成苗率8.1%。初步实现了糙海参苗种规模化生产。In order to increase the resources of rough sea cucumber Holothuria scabra in tropical sea,key techniques of large-scale breeding were established.From June 2014 to May 2015,the rough sea cucumber collected from the sea of Lingshui county,Hainan province were used as broodstock ones.The techniques of transporting broodstock,broodstock rearing,inducing broodstock to spawn,and culturing larval and juvenile rough sea cucumber were explored.Results showed that the survival rate of broodstock rough sea cucumber reached 99.8%when they were transported in aerating plastic bags.The survival rate of breeding broodstock rough sea cucumber in this study was above 97.1%.The success rate for inducing broodstock rough sea cucumber to spawn was 93.3%using the combination of cool drying and flowing water methods.In this study,12 batches of early auricularia and seedling cultivation experiments were carried out,and a total of 54.74 million early auricularia were cultured and 4.459 million juveniles with body length of 1.0—5.5 cm were cultivated with total survival rate of 8.1%from early auricularia to juvenile.The large-scale production of rough sea cucumber seedlings was preliminarily realized.
