海南岛罗非鱼养殖气候适宜性分析

依据1981—2010年的气象资料对海南岛气候资源进行分析,探讨海南岛罗非鱼养殖的气候适宜性。结果表明,海南岛罗非鱼养殖全年气候条件均较优越。各地全年平均气温适宜罗非鱼的养殖,尤其是5—8月温度普遍较高,罗非鱼生长最快;全岛降水充沛,利于养殖池塘水质更新;日照充足,利于保持养殖水体溶氧量。每年1—2月易出现低温阴雨天气,夏季强降水时易出现漫堤现象,建议海南岛罗非鱼养殖在这期间应做好灾害性天气的应对工作。

Analysis on Climatic Suitability for Aquaculturing Tilapia in Hainan Island

Based on the climate data during 1981 to 2010,the climate characteristics of Hainan Island for culturing Tilapia were analyzed.The results showed that annual mean temperature of Hainan Island was suitable for culturing Tilapia,especially from May to August.The abundant precipitation was useful for water quality and the abundant sunshine was useful for improving oxygen content in culture pond.However,the cold and rainy weather from January to February was harmful,and the heavy rainfall in summer often caused overtopping dam,so climatic service for culturing Tilapia should be strengthened to defense the meteorological disasters.
