水体 pH 值是反映水质是否适宜鱼虾生长的重要指标,决定着水体中的生物繁殖和水质的化学状况,直接影响鱼虾的生长。1、鱼虾最适宜的 pH 值为7.0～8.5,超出这个范围鱼虾就会受害。pH 值高于8.5,时间超过24小时,会使鱼鳃组织因受腐蚀而患烂鳃病;低于7.0,会使鱼虾血液循环 The pH value of water body is an important index to reflect whether the water quality is suitable for the growth of fish and shrimp. It determines the biological reproduction and the chemical status of water in the water body and directly affects the growth of fish and shrimp. 1, the most suitable pH value of fish and shrimp 7.0 to 8.5, beyond which fish and shrimp will suffer. pH value higher than 8.5, for more than 24 hours, will cause the fish gill tissues suffering from rotten gill disease; less than 7.0, will fish and shrimp blood circulation
