红螯螯虾自1990年开始引进我国以来,先后在广东、湖北,福建、海南、上海、江苏等地多点试养、繁殖,开展了不少科学试验与养殖探讨。但由于红螯螯虾具有一定区域适应性,仅靠其自然繁殖、种苗难以形成大批量,而且供苗季节性强。因此,目前苗少、价高,养殖成本大,难以形成商业性大规模养殖,仍处于探索养殖的阶段。 为了共同探讨红螯螯虾养殖实用技术及关键措施,现将我们三年试验试养实践体会,并参考国外有关资料小结初报如下:
Since its introduction into China in 1990, the red crayfish has been tested and multiply in Guangdong, Hubei, Fujian, Hainan, Shanghai and Jiangsu, and many scientific experiments and aquaculture have been conducted. However, due to the availability of a certain area of red crayfish, relying on its natural breeding, seedlings difficult to form large quantities, but also provide seasonal strong. Therefore, at present, less seedlings, high prices, breeding costs, it is difficult to form commercial large-scale breeding, still in the exploration and breeding stage. In order to jointly explore the practical technology and key measures of crayfish breeding, now we try the experience of three years trial practice, and reference to the relevant foreign summary of the first report as follows:
