<h3>水是生命之源,一切生命皆是水成就的鲜活精灵。水生动物更是离不开水,水质好坏直接影响水产养殖经济效益。
有经验的养殖户“看”水色,“判”水质。
水色是由水体中浮游生物及底栖生物的种类决定。浮游生物的大量繁殖是决定水色的重要原因。
浮游植物---藻类大量繁殖具有两面性,既为水生动物提供饵料,也能因气候骤变、缺氧死亡,发黑发臭,污染水质,造成养殖动物中毒死亡。
这种水色好不好?下面的介绍很明了。
1、茶褐色水
以硅藻为主,绿藻为辅,含有硅藻、角毛藻、菱形藻、舟形藻、小球藻等,是养殖的优良水色,透明度35-40厘米。<br></h3> <h3><br></h3><p style="max-width: 100%; clear: both; min-height: 1em; color: rgb(51, 51, 51); font-family: -apple-system-font, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif;
