伊河滩黑斑蛙养殖试验初探

Tentative Study on Breeding Experiment of Pelophylax Nigromaculatus in Yihe Beach

采用“稻蛙共养”的模式进行黑斑蛙养殖试验,试验面积9.23 hm^(2)。共投放黑斑蛙316万只,年收获商品蛙77 t,半成品61 t,年总产值433.2万元,平均产值46.95万元/hm^(2),均纯利润27.6万元/hm^(2)。养殖模式存在的主要问题:黑斑蛙种质质量较差,进排水系统不规范,管理技术水平较低,没有开展育养分离养殖模式。

The mode of " coculture of rice and frog " was used to carry out the breeding experiment of Pelophylax nigromaculatus. The test area is 9.23hm^(2). A total of 3.16 million frogs were put in, with an annual harvest of 77000 kgs of commodity frogs and 61000 kgs of semi-finished products. The annual total output value was 4.332 million yuan, the average output value was 469500 yuan/hm^(2), and the average net profit was 276000 yuan/hm^(2). The main problems of the breeding mode are: the quality of black spotted frog germplasm is poor, the water inlet and drainage system is not standardized, the management technology level is low, and there is no separate breeding mode.
