摘要
在虾池周围打机井、挖平塘，用地下水作水源，实行对虾封闭式淡化养殖，切断了海水污染源。结果：１１００亩虾池平均亩产对虾１０５ｋｇ，规格１２ｃｍ，尾重２０ｇ。共产对虾１１２ｔ，产值８９６万元，投入产出比１∶２９。专家鉴定认为，技术水平属国内先进。
An experiment on prawn culture in the enclosed and desalinized sea water was conducted by means of driving wells and pools around the prawn pond for using the underground water as water supply to cut off the polluted sea water.The experimental result shew that the average per mu yield was 105kg of prawns in the ponds with the total area of 1100 mu.The size of the commercial prawns was 12cm and the individual body weight was 20 g on average.The output price was 8.96 million yuan and the ratio of input and output was 1∶2.9.The technical level appraised by experts has met the advanced standard at home.
