1. Derris poisoning. In real life, we often see the phenomenon of using derris to poison fish in small rivers and streams, and a slight carelessness often threatens the pond fish being raised. At this time, the best method is to first block the toxic water from entering the pond; at the same time, splash human urine diluted with water over the whole pond. The dosage is about 25 kg of human urine per 1 mu of water surface at an average depth of 1 m (that is, 667 cubic meters), diluted with water to 50 kg, then splashed evenly over the whole pond. This has an obvious effect on rescuing fish that have just been poisoned or have not yet been poisoned. 2. Tea seed cake poisoning. Tea seed cake is usually used to poison ponds or in small amounts to prevent and treat fish diseases,

This has an obvious effect on rescuing fish that have just been poisoned or have not yet been poisoned.

II. Tea seed cake poisoning. Tea seed cake is usually used to poison ponds or in small amounts to prevent and treat fish diseases, but sometimes the work is rough and the dosage is not measured accurately, causing losses that should not happen. Rescue method: first, inject clean (river) water with high dissolved oxygen and no pollution into the pond (absolutely do not enter the pond to stir); then for each 1 mu of water surface at an average water depth of 1 m, use 0.5 kg of tung oil diluted with 25 kg of water and splash it over the whole pond. This can effectively rescue fish that have just been poisoned.

III. Organophosphorus pesticide poisoning. The reactions of fish poisoned by organophosphorus pesticides are often: the fish leave the school and dart about wildly, and when the caught fish is examined by opening the gill cover, bleeding is seen in the gill filaments, with no other marks on the body. At this time, the best rescue method is: first inject unpolluted river water with high dissolved oxygen into the pond, then use 25-30 kg of yellow mud plus 30-40 kg of human urine (per 1 mu of water surface at an average depth of 1 m), stir evenly, and splash over the whole pond; then use "atropine" at a ratio of 1 g per cubic meter of water and splash it over the whole pond (for broodfish, injection may be used). This has a certain curative effect on rescuing fish poisoned by organophosphorus pesticides.
