夏季天气炎热,水温较高,为确保河蟹安全度夏,提高成活率,促进河蟹快速生长,池塘养蟹管理工作尤为重要。1加强水质管理在炎热盛夏季节,蟹池表层水温有时可达30℃,对河蟹生长不利,水温22～25℃适宜河蟹生长。水温太高,水质易恶化,造成水体溶氧不足,河蟹纷纷离开水体,爬到池坡,摄
Hot summer weather, the water temperature is high, in order to ensure the safety of crab summer, improve survival rate and promote the rapid growth of crab, pond crab management is particularly important. 1 to strengthen water quality management In the hot summer season, crab pool surface temperature sometimes up to 30 ℃, detrimental to the growth of crabs, water temperature 22 ~ 25 ℃ suitable for crab growth. Water temperature is too high, water quality is easy to deteriorate, resulting in lack of dissolved oxygen in water bodies, crabs have left the water body, climbed to the pool slope, photo
