我们于1995年在福建省连城连峰镇三个村推广虾60.4亩,当年平均亩产达121.5kg,获得成功。1996～1998年,通过不断改进、提高,养虾成本逐年降低,单产逐年提高,在市场虾价四年降幅50%的情况下,保持亩均年盈利5000元左右,取得较好的经济效益。以有原始记录的大坪村外坊段自然村示范点为例,四年累计养殖水面78.4亩,产虾12953kg,产值762288元,盈利420504.5元,四年亩均单产165.2kg,亩均盈利5363.6元。现将有关技术总结如下:
In 1995, we promoted 60.4 mu of shrimp in Sanjian Village, Lianfeng Town, Liancheng City, Fujian Province. In the same year, the average mu yield reached 121.5kg, which was a success. From 1996 to 1998, through continuous improvement and improvement, the cost of raising shrimp decreased year by year and the yield per hectare increased year by year. While the shrimp price in the market dropped by 50% in four years, the average annual profit of mu was about 5,000 yuan, which achieved good economic benefits. Take the original record of Daping Village Wafangdian Village demonstration site as an example. In the past four years, a total of 78.4 mu of aquaculture water surface had been produced, producing 12,953 kg of shrimp. The output value was 762,288 yuan and the profit was 420,504.5 yuan. The average yield per mu in four years was 165.2kg, with a profit of 5,363.6 yuan per mu. Now the technology is summarized as follows:
