Problems of "water swimming" in the process of sea trout farming

Recently, there are many ponds that raise sea lice. They will see squid swimming on the surface. This occurs in about 5 out of every 10 ponds and in 6 ponds. If the whole is concerned, as long as the ponds have been farmed for more than 3 months, this will happen. However, some cases are serious, some are relatively light, and lighter ones are normal. It is a common phenomenon that "water swimming" occurs during the breeding process.

The sea otters swim at a depth of about 10 centimeters away from the edge of the pond. When the time is hidden, swimming is not effective. The net is easy to pick up. It usually appears in the morning and evening. The situation is serious, and you can see dozens of times. Even a few hundred.

In the process of breeding, sea otters will appear to have "drinking water" phenomenon that is a disease, that is, the traditional "season disease."

Parasitic disease: As it is now in the high temperature season, it is also the main period of parasite outbreaks, especially the ringworm, the third generation of insects, and trilobites are the main insect pests in this period.

Bacterial disease: The high temperature season is also the main period of bacterial outbreak. Vibrio, Aeromonas, Pseudomonas, Nocardia, etc. are the major bacterial diseases in this period.

Hepatobiliary Syndrome: During the high temperature season, sea otters eat more, and sea bream protein is high, so it is easy to show hepatobiliary syndrome such as flower liver and white liver.

Ammonia nitrogen, nitrite exceeded: the high temperature season, eat much more, the pollution of the water will naturally increase, so often there will be ammonia nitrogen, nitrite exceeded the standard, especially nitrite, generally have more than 0.15, some Even more than 0.3.

In the above four aspects, is it caused by some aspects that Haishu has “swept water”, or is it that many aspects jointly cause Haishu to “swamp”? On the whole, the result of the "swimming" of sea otters is the result of the joint action of many parties.

In terms of the situation of jellyfish “water swimming”, it is mainly caused by insect pests, especially the ringworms. It can be said that during this period, all “fish swimming” fish will see the ringworm, and the amount is quite large. After killing insects by spraying drugs, , can effectively reduce the fish "water" phenomenon.

In fact, the "fish swimming" fish will not only find a large number of ringworms, but also appear to have a flowering liver phenomenon. From 2nd to 3rd and 2nd to 1kg of fishes, there will be a "cabbage" phenomenon. It can be said that "fish" is always a fish. Hepatobiliary syndrome is present.

Another point is that most of the “fishing” fish ponds are obviously yellowish and turbid, and nitrite is significantly higher or even exceeds the standard. In some fish ponds, there are symptoms such as bleeding and ulceration on the surface of the jellyfish, which are mainly caused by bacteria.

A farmer can actually reduce the “fishing” phenomenon of fish by killing the ringworm, but after 1 month at most, the phenomenon of “water swimming” will continue to appear. Therefore, reducing fish “water swimming” by killing insects is only a symptom. The only way to cure this problem is to make the water quality worse after killing the insects, especially the nitrite will rise even higher. Therefore, the method of killing insects can not effectively cure the "fishing" problem of fish.

If we want to fundamentally solve the problem of "fishing" of fish, we must start from solving the deterioration of water quality. The main reason for the deterioration of water quality is caused by large amounts of feed. Therefore, if we want to fundamentally solve the problem, we must first start with the control of feed, reduce the amount of feed, regular use of microbes to transfer water, regular internal microbiology to reduce feed water pollution, so as to fundamentally solve the fish "Walking water" problem.

The prevention and control of diseases is a systematic project. It is impossible to deal with the problems of the head and feet, and we must look at the source to see the root of the problem.

Not only will the Begonia have a problem of “swimming water”, other fish, such as the Californian fish, yellow croaker, and blind fishermen, will also have similar problems, and the situation will be similar to that of a sea otter. Therefore, you can refer to each other to solve the problem. Disease control is the same.
