The disease was easy to repeat and difficult to control, and was diagnosed as fulminant hemorrhagic disease of silver carp and bighead carp. The harm of this disease is great, and mariculturists should attach great importance to it. First, the epidemic situation: it is easy to become prevalent in March-May and August-October every year, and the mortality rate of the disease is as high as 70%.

The effect of rare earth feeding on fish is good.
Rare earth refers to the general name of 17 metal elements in the periodic table, including lanthanum, praseodymium, neodymium, cerium, samarium and so on. Among them, cerium accounts for 48%, lanthanum 25%, neodymium 16%, praseodymium 5%, samarium 2%, and other 12 elements 4%. In recent years, rare earth has become an important resource for national economy and national defense construction. Not only can it be widely used as an industrial vitamin in metallurgy, machinery, petroleum, chemical industry, light industry, electronics and other industries, but also can be used as micro-fertilizer in agricultural production. In fishery production, feeding rare earths to fish also has a very good effect. According to the test

What is the "sexual transformation" of female swordtail fish?
The so-called "sexual transformation" of female fish refers to the gradual masculinization of some female fish that have given birth to larvae: the body becomes slender, sword-shaped protuberances grow under the caudal fin, and the anal fin turns into a rod-shaped mating device, and begins to chase the female, mate and fertilize with it, and reproduce. However, only the female changed from male to male, and no male to female was found. Recently, different opinions have been expressed on this issue: swordtail fish cannot be reversed sexually, and their natural sex ratio has always been between 1:2 and 1. 5. Although the larvae of swordtail fish grow to 3 months, the reproductive organs of both sexes open.

Ecological distribution of dace
Mud carp is a warm water fish. when the water temperature is 15-30 degrees, the mud carp have a strong appetite. When the water temperature is higher than 31 degrees, the mud carp lose their appetite; when the water temperature is below 14 degrees, the mud carps gather in the deep water area; when the water temperature is below 13 degrees, they stop feeding; when the water temperature is below 7 degrees, they cannot survive. Due to the poor cold resistance of mud carp, overwintering mud carp cultured in ponds in the Pearl River Delta are usually kept in deep ponds sheltered from the wind and sunny, and sometimes cold protection measures are needed. In the wild fish ponds in the mountains of northern Guangdong, it is difficult for mud carp.

Trace elements needed for raising clown fish
Of course, to raise marine fish, there must be "sea water", and natural sea water is of course the most suitable for raising, but due to environmental pollution, it is not the most appropriate way to use sea water drawn from the seaside, and it is necessary to extract deep sea water from the open ocean. The sea water absorbed from the ocean must go through many treatment steps before it can be used. First of all, the containers for storing sea water must not use metal containers, because the ions of these metals will dissolve in the water, thus harming the health of the aquarium. Secondly, it should be sealed and stored in the sun.

There are seven tricks to improve the efficacy of internal administration of fish medicine.
First, the difference between prevention and treatment lies in the prevention of fish living in the water, the condition is hidden and difficult to detect. Once dead fish is found, the loss is great, and the treatment of fish disease is more difficult, which brings a lot of inconvenience. Therefore, we should actively implement the guiding principle of "no disease first prevention, early treatment of disease, prevention is more important than treatment", and establish the concept of prevention and drug application. Second, the skillful combination of traditional Chinese and western medicine in the treatment of fish disease has the advantages of long effect, few side effects and low cost of prevention and treatment. Western medicine has the characteristics of rapid efficacy and high cost. Practice has proved that it is effective.

How to select soft-shelled turtle

Therefore, using artificial methods to strengthen the cultivation of soft-shelled turtles is the main key to solve the source of soft-shelled turtles and develop the production of soft-shelled turtles. The following problems should be paid attention to in the selection of soft-shelled turtles. 1.
