摘 要:2001年6月27日将3 5万尾平均规格为2 2g 尾的金鱼放入0 267hm2试验稻田,放养密度为13 125万尾 hm2。经3个月的饲养,产金鱼3 3万尾,平均规格达20 5g 尾,成活率为94 3%,投饲料300kg,节肥860kg hm2,水稻增产600kg hm2,经济效益显著。实验证明稻田养殖金鱼是可行的。It's found that the artificial culture of gold fishes in rice fields is feasible.35000(2.2 g/ind in average specifications)gold fishes were reared in 0.267 hm2 experimental rice field on 27 June,2001.The average density of the seedling was 131250ind/mu.33000ind gold fishes were produced and average specifications were 205g/ind during 3 months in the experiment.The survival rate was 94.3% and 300 kg forages were haven raised.Having saved 860 kg/hm2,rice having increased production 600 kg/hm2
