| 为了解决白沙参参苗个体小、抗逆性及抵御敌害生物的能力弱、成活率低、不利于增养殖的缺陷，研究了白沙参室内水泥池中间培育过程中的关键参数，并在最优条件下进行室内水泥池和室外池塘网箱的培苗，试验结束时测量参苗的体长和体重，计算成活率。结果表明，室内水泥池培育的关键技术参数如下：水温25~30℃，盐度25%~35%，培育密度2 000~3 000 头/m2，光照强度2000lx。在上述最佳条件下，将体长0.3~0.5 cm、体重0.004 g的参苗16 万尾，置于室内水泥池培育1个月后，参苗规格平均达到0.8~1 cm，存活率达到50%以上。然后将其转到室外网箱培养，更换网箱规格并及时疏苗，培育40d时，参苗规格平均达到3cm左右，存活率达到60%。 |

| In order to solve the problems including small individual, weak stress resistance and ability to resist diseases, low survival rate of Holothuria scabra Jaeger larvae, this paper studied the key techniques in the process of intermediate rearing of H. scabra Jaeger with indoor cement pools, reared H. scabra Jaeger juvenile under the optimal conditions combined indoor cement pool culturing and outdoor pond culturing, measured body length and body weight at the end of the test, and calculated the survival rate. The results showed that, the optimal conditions of indoor cement pool cultivation were as follows: temperature of 25-30℃, sanity of 25%-35%, density of 2 000-3 000 individuals/m2, light intensity of 2 000 lx. Under the above optimum conditions, 160 thousand juveniles with 0.3-0.5 cm in body length, 0.004 g in weight were cultured in indoor cement pools. After 1 month, the average body length of juveniles reached 0.8-1 cm, the survival rate reached more than 50%. Then the juveniles were cultured in outdoor ponds, after 40 d, the average body length of juveniles reached about 3 cm, the survival rate reached 60%. |
