Catfish is not a dirty fish;

Catfish are omnivores. Its main food includes aquatic insects, organic debris, eat small fish, mice and other creatures, and even eats the same kind of corpses when it is not full.

Because catfish is omnivorous and has strong vitality, it can survive in polluted water. Catfish can survive in some sewage environments with chicken manure and pig manure.

Moreover, in aquaculture, animal manure is also a cheap and non-toxic natural fertilizer, which provides a lot of nutrition for plankton in the water, so many farmers will use chicken manure and pig manure as feed.

However, feces contain a lot of parasites and pathogenic bacteria, so it can't be directly poured into the pond for use, otherwise it will affect the health and safety of fish. Therefore, before use, it is necessary to do fermentation treatment to completely kill parasites and pathogenic bacteria, and decompose the macromolecular protein in feces into the easily available micromolecule protein and nutrients.

As for other waste water and garbage, it is also not allowed to pour directly into the farm, otherwise it will greatly affect the health and output of fish, and regular farms will not do such a loss-making thing.

According to the fact that catfish can survive in dung water, it is unscientific to draw the conclusion that catfish is dirty and loves to live in dirty water. Catfish don't like polluted water. Moreover, the tolerance of catfish to the environment is limited.

If the water quality is poor, catfish not only have difficulty in reproduction, but also have poor growth. If the water contains toxic and harmful substances, catfish will be poisoned or even die.

The experimental study on the toxicity of heavy metal cadmium in water to fish shows that when cadmium in water reaches a certain concentration, mandarin fish, crucian carp and catfish will all die of poisoning, but catfish has stronger anti-poisoning ability, resulting in higher poisoning dose.

The acute toxicity tests of sodium dichloroisocyanurate, bromochlorohydantoin and diclofenac on catfish were also studied. The results show that when the concentration of these pesticides increases, catfish will also have poisoning reaction and even serious death.
