2013年7月，在海上贝架养殖区0．6 m×0．6 m×1 m的小型网箱中，利用天然饵料培育大规格糙海参参苗。经95 d培育，参苗平均体长由1．13 cm长至3．24 cm ，日均增长0．02 cm／d ；平均体质量由0．04g增至0．84g，日均增加质量0．008g／d，体质量增加20倍，成活率为57％。前25d内参苗快速生长，成活率明显下降；此后参苗生长和成活率变化缓慢并趋于稳定。试验结果表明，在天然海区利用小网箱培育糙海参大规格参苗的方法可行，但培育效果尚不理想，需进一步改进提高。

Sandfish Holothuria scabra juveniles with average initial body length of 1 .13 cm and body weight of 0.04 g were reared in three net cages with the size of 0 .6 m × 0 .6 m × 1 m at a frame site for shellfish culture on open sea for 95 days .The results showed that the juveniles had average final body length of 3 .24 cm ,with daily growth of 0 .02 cm ,and final body weight of 0 .84 g ,with daily weight gain of 0.008 g ,as 20 times large as the initial body weight ,and with survival of 57% .The best growth of the juveniles was observed in the first 25 days of the experiment with steady lower survival rate ,thereafter the growth and survival rate of the juveniles was found to be changed slowly and keep stable until the end of the experiment .The findings indicated that sandfish juvenile culture in net cages on the open sea was technically feasible ,but the effects were far from the ideal and further study is needed for improvement of the techniques .
