Why is fish disease difficult to treat? Characteristics of fish disease

In our country, no matter what kind of fish is, there are certain consumer groups. The technology of fish culture is not very difficult, and the output is relatively high. However, in fish farming, once fish disease breaks out, the loss of benefits suffered by fish farmers will be very great, and even lead to no harvest, because fish disease has four major characteristics, which is very difficult to treat. So what are the specific characteristics? The following editor will give you a brief introduction, let's have a look!

1. Group

Fish disease has a strong group, such as bacterial septicemia, grass carp hemorrhagic disease and other diseases, as well as rotifer, sporidium and other parasitic diseases have group characteristics. Once these diseases occur, they can cause disease in most fish within days or even hours. In serious cases, the whole pond fish will get sick and the phenomenon of empty pond will appear. Because the area of the disease is very wide, it is difficult to regulate and control the fish disease in time, even if the treatment is timely, then the loss is also very great.

2. Explosive

In fact, the characteristic of explosion is similar to that of the group. Explosive means that the spread and incidence of fish disease are very fast, after the onset of fish disease, must be treated as soon as possible, the urgency of fish disease rescue is very important. There is not enough time, and there is no way to adjust the treatment at the same time. Therefore, when we raise fish, we must often observe the growth of the fish, once the abnormal situation occurs, then we must carry out timely treatment, otherwise it may lead to the end of harvest.

3. Complexity

Fish disease prevention and control is a fish culture technique that all mariculturists need to fully understand when raising fish. We should have varying degrees of understanding of the characteristics, symptoms, prevention and control methods of fish disease. Many mariculturists do not pay too much attention to the prevention and treatment of fish diseases, resulting in ignoring the complexity of fish diseases. Fish disease is actually very complicated. In the event of an outbreak of fish disease, a treatment may be effective for this fish pond. However, when the same disease occurs in another fish pond, this method may lose its effect, so we must pay more attention to it.

4. Repetition

Repetition is another feature of fish disease derived from complexity. There is still no standard for clinical treatment of fish disease, no matter how experienced fish farmers are, there is no guarantee that they can be cured in a short period of time. Most fish diseases are very stubborn, and the frequency of fish diseases usually has a high recurrence rate. The same fish disease may occur many times over and over again, and a variety of diseases may occur on one fish. Or different diseases, which occur repeatedly with each other, are very difficult to treat.

The above is a brief introduction to the characteristics of fish disease and why it is difficult to treat. This is the end of today's introduction, this article is for reference only, I hope it can be helpful to everyone!
