采用6只池塘(0.14公顷/只)进行斑节对虾的生长试验,共放养对虾后期幼体(PL_(25～27))60万尾,一直养至上市规格起捕。池塘深2.2米,每只池塘还配置1马力的叶轮式增氧机两台。对虾只投喂市售的配合饲料,日投饲0～4次。四个半月后,收获对虾848～1550公斤/0.14公顷,平均为1212公斤/0.14公顷。单产高达每茬8.7～21吨/公顷。将这种高度集约化养殖系统的产量,与以律报道的对虾产以及对部分养虾场所作的调查结果进行比较,发现放养密度与单位产量和平均产量/公顷/日呈线性相关;池塘面积与放养密度、单位产量及平均产量/公顷/日之间为负指数关系。试验表明,在有限水体中,通过高密度放养和增加池塘深度,能提高其生产力。
Six ponds (0.14 hectare / bird) were used to test the growth of P. monodon. A total of 600,000 PL larvae (PL_ (25 ~ 27)) were stocked and raised to market specifications. Pond 2.2 meters deep, each pond is also equipped with 1 horsepower impeller aerator two. Shrimp feed only commercially available with feed, feeding 0 to 4 times. Four and a half months later, prawn 848-1550 kg / 0.14 hectares were harvested, with an average of 1212 kg / 0.14 hectares. Yields up to 8.7 ~ 21 tons / ha per crop. Comparisons of yields of such highly intensive farming systems with those reported as legumes and surveys of some shrimp farms showed that stocking densities were linearly related to unit yields and average yields per hectare per day; pond area It has a negative exponential relationship with stocking density, unit yield and average yield / ha / day. Experiments have shown that in a limited body of water, its productivity can be increased through high density stocking and increased pond depth.
