| 摘要: |
| 对凡纳滨对虾的养殖采用新的投料和管理方法,不施肥,从放苗后2h开始投料,并由2餐/d改为5餐/d;管理上采用不施抗生素药物的生态养殖模式。定期抽样测量对虾的体长。结果表明,实验对虾生长速度比对照塘提高20%～30%,成活率高达86.33%,比对照塘高约20%。实验证明该方法值得推广。 |

| Abstract: |
| A new feeding strategy in Litopenaeus vannamei; culture was experimented. In the new procedure, no fertilizer and antibiotics is needed. The feeding started 2 hours after the stocking, and increased from 2 meals/d to 5 meal/d. Periodic sampling was done for size measurement. The results show that the shrinp grouth rate was erhanced by 20%～30% cowparing to regnlar-feeding control group; and the survival rate was as high as 86.33%, improved by 20%. |
