摘要
在近岸潮间带建设潜堤,并在堤顶设置拦网是一种新型的对虾人工养殖设施。这种潜堤网拦养殖设施,在涨潮时,海水越堤而过,注入池内;退潮时,利用拦网防逃,潜堤贮水,实现自行换水。该设施投资小,节省能源,管理方便,产量高。本文通过两个已建工程的设计,说明这种养殖设施的可行性,并提出潜堤和拦网设计中的各项参数的确定方法。
A new type of installation for prawn culture is designed and a sub-merged dike provided with net-screen is built on the pond in intertidal zone. Whenthe tide is coming in, sea water can overflow the dike into the pond. The dike cankeep enough water in the pond and the net screen will prevent the prawn fromescaping when the tide is going out. In such a way the sea water in the pond is self-exchanged. Therefore, this installation is very economical, low cost, energy-saving,easy to manage, and high in production. Two completed projects were built and theexcellency of the installation has been proved.
