| 摘要: |
| 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。 |

| A TRIAL PRAWN CULTURE IN NETTED POND IN INTERTIDE ZONE |
|
|
| Abstract: |
| The prawn culture in netted pond is conducted on the middle and low tide zone with the net sticked in the low dam. This cultural method has the advantages of being easily built, lowcost because of flood and ebb tides, saving a lot of energy, good water quality, preventing the occurrence of prawn disease and improuing of feed utilization. Certain problems can also be solved such as pollution and bottom worn-out in the cultural areas. In 1986, 100mu netted ponds were built, harvesting prawn about 16141.5kg and making a profit of 126855.66 yuan. This is a new way for prawn farming with high output, good quality and low production cost. |
