摘要
在分析池塘渔业灾害成因基础上，运用鱼类学、生态学、自然灾害学原理，提出在池塘一角建造一个面积占池塘总面积10％～15％、深1．0～1．5m的鱼潭，以扩大池塘空间和鱼类避灾活动空间，增强调水功能，从而有效防止旱灾、冻灾和一定的洪涝发生，使池塘养殖处于生态安全状态。同时方便渔业管理，利于产业发展。该方法的防灾减灾能力与实施面积呈正相关。
Based on the analysis of causes of pond fishery disaster, utilizing the principles of ichthyology,ecology and natural disaster science, it is suggested that fish pound can be built at a corner of pond with area of 10-15 % of the pond and depth of 0-1.5 meters aiming at expanding the usage space of pond and space of disaster shelter for fish, enhancing the function of water transfer, preventing drought, frozen and flood disaster efficiently and making pond fishery breeding in safe ecological condition. At the same time, this is convenient for fishery management and favorable to fishery development. It is a positive correlation between disaster prevention and mitigation and the area of this kind of fish pound.
