Man-made causes of disease in baby fish

Some common phenomena of artificially causing diseases in baby fish

Improper packaging and packaging methods for long-distance transportation lead to extrusion, overdensity of individuals, friction, collision, temperature and other factors on the road, which lead to the most common outbreak of intestinal diseases in baby fish. because of the viral cold disease caused by the temperature difference, many novice buyers saw a good end when they sold the seedlings, but they returned home and the seedlings floated, died, and stopped eating. The problem is that they did not stop eating the baby fish during transportation, did not give the baby fish stress prevention, the packaging method was wrong, how much water was not sure, the temperature control was wrong, and when I got home, I did not pay attention to the temperature difference between the box and the pool, which led to the emergence of a baby fish viral cold, such as the smallest 4 cm seedlings, and the temperature difference was too large, which would lead to the premature death of the baby fish seedlings on the spot.

The bait fed is not sterilized, the disinfection drug dosage is incorrect, or it is not sterilized at all, especially Loach, rice field eel, frog, toad, fish in ponds and shrimp in river ditches, which carry a large number of microorganisms in any season. many people go to the mountains, ponds and ditches to catch their own bait, which is basically something in the wild, and there are countless microbes carried in the wild, especially in autumn. In spring and summer, the possibility of these baits carrying the virus is very large. Some baby fish raised by people suffer from unknown diseases. I think bait is the culprit. People who raise baby fish do not pay attention to the source of the bait, but control the door to death. They always think that as long as people do not look at it, they will not spread the disease. Seriously, people who look at baby fish will get sick. This is basically not true. Unless the viewer maliciously carries the pathogen into the pool.

Improper use of drugs, some fish, individual problems, ask around what medicine is the most effective, go home to give the baby fish hard to cure the disease, any drug three points of poison, excessive will lead to the baby fish die, many fish farmers of the baby fish are not sick to death, but are cured, the amount of medicine used and the baby fish individual size, the amount of water in the pond, different seasons, different temperature The combination of such factors can give an appropriate dosage, especially the first use of drugs must be less, and some people use the same amount of drugs for the first time as for the second time, but the disease is cured for the first time, but not for the second time. The reason is drug resistance.

The common drugs that poison baby fish in China are povidone iodine, chlorine dioxide, potassium permanganate, salt and malachite green. If these drugs are used properly, they will have a good effect. If the dosage is not enough, it will not achieve the effect. The real use of chlorine dioxide is to sterilize and disinfect the pond utensils, but the premise is to fish the baby fish out. The biggest mistake for beginners is to throw chlorine dioxide without fishing for fish.

Artificial heating in winter causes indoor temperatures to rise and fall, resulting in baby fish viral colds. In the coming year, such seedlings will be very sad in summer, and the outbreak of extremely poor disease resistance is very likely.
