Last Updated: 2024/11/08, Pellet feed is used to feed carp, grass carp, mackerel, white Pomfret, crucian carp, etc., due to a large amount of feeding, feces and leftovers increase, the nitrogenous substances produced by protein decomposition increase, a little carelessly, these fish will have ammonia nitrogen poisoning, light will affect normal growth, serious will cause the death of fish. The identification and rescue methods of ammonia nitrogen poisoning in pond fish are introduced as follows. 1. Identification of poisoning. 1. Occurrence characteristics. Ammonia nitrogen poisoning, there is no season, morning and evening and the weather is good or bad, more common in adult fish

Feeding carp, grass carp, bream, white pomfret, crucian carp, etc. with pellet feed, due to large feeding amount, excrement and residual food increase, nitrogen substances generated by protein decomposition increase, a little carelessness, these fish will occur ammonia nitrogen poisoning, light will affect normal growth, serious will cause fish death. The identification and rescue methods of ammonia nitrogen poisoning in pond fish are introduced as follows.

I. Identification of poisoning

1. Characteristics of occurrence. Ammonia nitrogen poisoning, no season, morning and evening and good or bad weather points, more common in adult fish ponds, high-yield ponds, closed culture ponds and can be irrigated can not discharge fish ponds.

2. Toxic symptoms. Fish breathe fast and swim wildly. After swimming slow, paralysis and weakness; then dark body, gills black, purple mouth, mucus increased; finally lost vitality, slowly sank to the bottom and died.

3. Oxygen is ineffective. After the pond fish ammonia nitrogen poisoning, turn on the aerator, the pond fish are scattered to avoid, dare not approach. The pelagic fish did not respond to the oxygenator.

II. Rescue measures

1. Add fresh water in time to reduce ammonia nitrogen concentration in the original pool and prevent poisoning from deepening.

2. Sprinkle salt to prevent ammonia nitrogen and nitrate nitrogen from continuing to invade fish blood. 17 kg of salt is available per 667 m2 of water surface.

3. Zeolite powder and medical stone powder are scattered to absorb harmful gases and toxic substances at the bottom of the pool.

4. After the poisoning has been alleviated, fungicides should be added to the water to prevent bacterial infection.
