利用塑料大棚晒水进行刺参种苗越冬试验

Wintering of Juvenile Sea Cucumber (Apostichopus japonicus) in a Plastic Greenhouse

2002年11月～2003年4月,在瓦房店市交流岛前哨海参育苗厂800 m^3水体室内水泥池中,投放平均规格为5000头/kg,刺参种苗196 kg（98万头）.在没有锅炉进行水加温条件下,利用600 m^3水体塑料大棚晒水进行刺参种苗越冬,水温2.0～13.2 ℃,平均盐度31.2,pH值8.2,DO＞7 mg/L,经过近6个月的培育,共培育出规格为876头/kg的参苗836 kg（73.2万头）,成活率74.7%,总重量增加了8.5倍.

Juvenile （5000 individuals/kg, total 196 kg） sea cucumber （Apostichopus japonicus） were wintered in m3 tanks in a plastic greenhouse without heating in Wafangdian Cucumber Hatchery from November 2002 to April 2003. Survival rate of 74.7% was observed in the juveniles with final body weight of 876 individuals/kg at water temperature of 2.0 - 13.2 ℃, a salinity of 8.2 and dissolved oxygen levels of above 7 mg/L.
