自90年代初期全国沿海地区暴发病毒性虾病以来,对虾养殖业一直在低谷徘徊。为调整养殖品种结构,提高现有虾池的综合使用效率,我们于2000年夏季在昌黎进行了虾池三疣梭子蟹的小规模试养,取得了比较理想的效果。下面,就将本次试养的技术体会总结如下: 1 准备工作 1.1 场地的选择 一般北方地区的养虾池均可,但以沙泥底质为佳,此外,还应具备较高的水交换能力。虾池面积以不超过1.3hm~2为宜。
Since the outbreak of viral shrimp in the coastal areas of the country in the early 1990s, the shrimp farming industry has been hovering low. In order to adjust the structure of breeding breeds and improve the comprehensive utilization efficiency of existing shrimp ponds, we conducted a small-scale trial of the swimming in the summer in 2000 in Changli, and achieved satisfactory results. Below, the trial experience of the technology will be summarized as follows: 1 Preparation 1.1 Site Selection General North shrimp ponds may be, but to sand sediment is better, in addition, should also have a higher water exchange ability. Shrimp pond area of not more than 1.3hm ~ 2 is appropriate.
