为适应我国加入世贸组织和市场经济的需要,优质、高产、高效、生态、安全的商品蟹已成为我国今后河蟹养殖生产的主要目标,这就要求河蟹养殖必需由“大养蟹”向“养大蟹”、“养好蟹”转变。现将其养殖技术总结如下: 一、产地环境与蟹池条件应符合要求 无公害河蟹生产基地应建在无“三废”(废水、废气、固定废弃物)污染的地点,环境空气质量符合《GB3095—1996标准》。要求水源充足、新鲜、无污染、水质良好,含氧量5mg/L以上,水质符合国家《GB11607—1989渔业水质标准》。生产设施布局与生态环境 In order to meet the needs of China’s accession to the WTO and the market economy, high-quality, high-yield, high efficiency, ecological and safe commodity crabs have become the main targets of our country’s crab farming in the future. This requires that crab farming must be transformed from “big crab” to “ Big crab ”,“ raise good crab ”change. Now its breeding technology is summarized as follows: First, the origin of the environment and crab pool conditions should meet the requirements of pollution-free crab production base should be built in the absence of “three wastes” (waste water, waste gas, fixed waste) contaminated sites, ambient air quality in line with “GB3095 -1996 standard ”. Requires adequate water, fresh, non-polluting, good water quality, oxygen content above 5mg / L, water quality in line with national “GB11607-1989 Fishery water quality standards.” Production facilities layout and ecological environment
