在潮间带中低潮区建筑矮小的土堤坝,插杆用网围成100亩对虾养殖池,进行生产性试验,取得了良好的效果。平均亩产161.4kg,当年盈利126855.66元。网围对虾养殖是一种新的养殖方式,它具有以下优点:(1)可以扩大滩涂利用面积,为充分利用潮间带滩涂开辟了新的途径;(2)建池方便、投资少,尤其适宜个体,联户养虾;(3)不需要机械抽水,可节约能源;(4)水交换量大,水质新鲜,虾池底不易老化;(5)对虾单产高,经济效益好。
In the intertidal zone in the low tide area of construction of a small earth dam, the plunger with a sieve into a 100-mus shrimp ponds for productive tests, and achieved good results. Average mu produce 161.4kg, then profit 126,855.66 yuan.
