Why do fish farmers die of old age in summer?

My father keeps fish at home, but he knows a thing or two about it. Let me help you answer the reason why fish die easily in summer and tell you how to prevent fish from dying easily in summer.

1. Causes of frequent fish diseases in summer

1. Water quality control problems

The main reason for the increase of fish diseases in high temperature season is that the organic matter in aquaculture water exceeds the standard, resulting in poor water quality. If pellet feed is used in aquaculture, it will aggravate the organic pollution of water, make the aquaculture water lack of oxygen, increase the content of harmful substances such as nitrite and ammonia nitrogen, and increase fish diseases.

⑷ irrational drug use

In the prevention and treatment of fish diseases, the method of "killing insects first, then sterilizing, preventing diseases and treating diseases" is usually adopted. In the case of intensive farming and high temperature in summer, this method is not only unrealistic, but also often leads to the deterioration of water quality, which is also a misunderstanding in aquaculture management. Pesticides and disinfectants will kill plankton in aquaculture water, make the water quality clear, increase the transparency of water body, reduce the dissolved oxygen content, and lead to the diffusion of hypoxia or the increase of nitrite and ammonia nitrogen content. If you don't eat them, fish poisoning or fish disease will occur.
