传统河蟹育苗中存在许多弊端,要提高河蟹育苗存活率,把好水质关是关键。在河蟹人工育苗过程中,水质条件的好坏在很大程度上决定着苗种的产量与质量。水质受多种物理、化学和生物因素的直接影响,经常处于较大的变动之中,因其检测手段的局限性导致盲目地大量使用抗生素和大量换水 There are many drawbacks in the traditional crab breeding, to improve the survival rate of crab breeding, the water quality is the key. In the process of artificial breeding of crabs, the quality of water quality largely determines the yield and quality of seedlings. Water quality is often directly under the influence of many physical, chemical and biological factors and is often undergoing major changes because of the limitations of its detection methods that lead to the blind use of large quantities of antibiotics and water changes
