The use of fishing medicine should be fine.
How to prevent and cure fish disease and how to use fishery medicine correctly is very important. If fishery medicine is not used correctly, it will bring economic losses to aquaculture farmers. In this regard, Li Zhengjun, director of the Fisheries Medicine and Fisheries Feed Department of the Sichuan Provincial Fisheries Bureau, said that some fishing drugs are banned by the state, and if they are used, it will lead to very serious consequences. It is hoped that aquaculture farmers will never use banned fish drugs. There are 32 banned fishery drugs, which are parathion, BHC, lindane, toxaphene, DDT DDT, calomel, mercurous nitrate,

Practical techniques for healthy culture of grass shrimp
Grass shrimp, scientific name Penaeus Monodon, also known as black shell shrimp, belongs to the family Penaeus vannamei. Because the shrimp likes to inhabit aquatic plants, it is called grass shrimp. Grass shrimp has the characteristics of fast growth, miscellaneous diet, wide salinity, short culture cycle, large individual, delicious meat, rich nutrition, high yield of adult shrimp and so on. Therefore, the shrimp has become an important object of current culture. The healthy culture techniques are introduced as follows: 1 the selection of shrimp ponds 1.1 should be in flat terrain, less silt, sufficient water source, good water quality and no pollution.

This phenomenon is especially serious and should be paid enough attention to. Rotifer harm to adult fish Rotifer harm to adult fish is mainly: Rotifer has super reproductive speed, in a short period of time will form a dominant population, eat most of the algae, so that photosynthesis reduced, oxygen production capacity weakened, at the same time it also consumes a lot of oxygen, the result is easy to cause fish deficiency

Matters needing attention in the Spring Festival Transport of Fish Seeds
Spring returns to the earth, and the water temperature rises gradually, which is the best time for the transportation of aquatic seedlings in a year. During this period, due to low water temperature, weak fish activity, strong fish body and tight scales, it is not easy to be injured in the process of transportation, which can improve the survival rate of fish species released in spring. There are many matters needing attention in the spring transportation of fish species, reminding the majority of fishermen to pay attention to them. 1. Pond disinfection should be done after removing excessive silt from the pond, strengthening the ridge and dredging it into the drainage channel, the general dry pond should use quicklime 200kg/ mu to make use of the slurry.

Seedling production of barracuda
The seedling production of mullet includes two steps: artificial propagation and seedling breeding. The former is divided into parent fish cultivation, induced spawning (artificially induced ovulation), artificial insemination, artificial hatching and other processes, while the latter is divided into two processes: fry cultivation and fingerling cultivation. In the study of artificial reproduction of grey mullet, the first artificial spawning of grey mullet was completed in Italy as early as 1930. It was not until the past 10 or 20 years that it attracted the attention of relevant countries in the world, and became an important topic in international biological research. China, the United States, India, the former
