CATDOLL : CATDOLL: Why do a lot of mineral elements accumulate in mandarin fish ponds in spring and summer?

In spring and summer, a large amount of mineral elements will accumulate in the mandarin fish pond. Most of the mandarin fish farming is fed with live bait (grass carp), and the feces excreted by mandarin fish contain too many large molecular proteins, oils, etc. The feces excreted by mandarin fish accumulate at the bottom of the pond. Under the hypoxic state at the bottom, it cannot complete assimilation and alienation, and eventually generates toxic and harmful substances such as ammonia nitrogen and nitrite. In particular, nitrite persists, posing a great threat to mandarin fish farming. Prevention is required: In August and later, it is recommended to use "biofloc bags" to hang bags once every 20 days, 5 mu/bag, to maintain water stability, balance bacterial phase, degrade harmful substances in the water, promote mandarin fish feeding, and reduce the accumulation of organic matter in the water. Use feces disinfection regularly, 2 mu/bag. Accelerate the decomposition of residual bait and feces in the mandarin fish pond, and reduce the accumulation of harmful substances, ammonia nitrogen, nitrite, hydrogen sulfide, etc. in the water.
