在鱼、虾育苗池、淡水养殖池以及观赏鱼养殖水体中,采用活菌数大于50亿/mL的光合细菌制剂改良水质,测定了使用前后水的pH、COD、氨氮、亚硝酸盐、溶解氧等指标,结果表明,光合细菌制剂的质量分数越高,改善养殖水体水质的效果越好。
In fish, shrimp nursery ponds, freshwater aquaculture ponds and aquaculture water for ornamental fish, the photosynthetic bacteria preparations with viable count of more than 5 billion / mL were used to improve the water quality. The water pH, COD, ammonia nitrogen, nitrite, dissolved oxygen The results showed that the higher the mass fraction of photosynthetic bacteria preparation, the better the effect of improving water quality in aquaculture water body.
