海水中溶解氧、ＰＨ值、氨氮含量的变化，对海产经济鱼类正常生活影响显著。当溶氧保持４ｍｌ／Ｌ以上、ｐＨ值８．０左右、氨氮０．０５～０．２９×１０－６时，鱼类正常生活。
Dissolved oxygen in seawater, PH value, ammonia nitrogen content changes, the impact on the normal life of marine fish economy significantly. When the dissolved oxygen to maintain 4ml / L or more, pH value of about 8.0, ammonia nitrogen 0.05 ~ 0.29 × 10-6, the normal life of fish.
