河蟹生态养殖中pH值与养殖效果的关系

Analysis on the Relationship between pH value for Ecological Aquaculture of Eriocheir Sinensis and aquaculture effects

河蟹（Eriocheir sinensis）生态养殖水体的pH值呈分区和分层变化,水体的pH值对河蟹的单位产量、平均规格有直接影响。调查分析认为,河蟹生态养殖最为适宜的pH值范围为8.5~9.5。

In this research We surveyed on the changes of pH value for ecological aquaculture of crabs, analyzed the relationship between pH value and unit production, the same as average weight of crabs, found out the phenomenon of partitioning and layering from the water for ecological aquaculture of crabs, put forward the optimum range of pH value for ecological aquaculture of crabs is 8.5 - 9.5.
