| 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 I.itopenaews vannarne ; 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 growp; and the survival rate was as high as 86.33%, improved by 20%. |
