摘要
淡水螯虾有540多种,在世界各地分布广泛,除非洲、南极洲之外均有自然分布。许多淡水螯虾种类例如克氏原螯虾、红螯螯虾、麦龙螯虾、雅氏螯虾、贵族螯虾和土耳其螯虾等经济价值较高,并有着多年的开发利用历史。淡水螯虾的生产主要有粗养、半精养以及精养等生产模式。我国以及许多欧美国家的淡水螯虾市场需求量较大,生产淡水螯虾利润较高。软壳淡水螯虾市场竞争力较强,产品供不应求,市场缺口较大。我国淡水螯虾分布广泛,产量巨大,而且其生产成本较低,在我国开展淡水螯虾的养殖尤其是软壳螯虾生产具有广阔的前景。
There are more than 540 species of crayfish in the world. Crayfish are widely natively distributed in the world except Africa and Antarctica. Some species of crayfish are well-exploited for years and have high economic value, including Procambarus clarkii, Cherax quadricarintus, destructor, Astacus astacus and Astacus leptodactylus. The crayfish aquaculture mainly includes extensive, semi-intensive and intensive types of production. The demand of crayfish market is very large in China and several western countries. The profit of crayfish production is very high. Soft-shell crayfish is high valued and greatly demanded. There is considerable potential for the development of markets for soft-shell crayfish. The development of crayfish culture in China is analyzed and it has a bright prospect to develop the industry of crayfish culture especially soft- shell crayfish production in China.
