Method for feeding rare earth-supplemented feed to broodstock and adult fish
Adding some rare earth in proportion to the bait fed to broodstock and adult fish can not only improve feed utilization, but also promote fish growth, enhance disease resistance, play a role in preventing and treating diseases, reduce fish deaths, and increase economic benefits. The preparation method for feeding broodstock is: use 40-50 grams of rare earth or 1 packet of rare earth additive, first dissolve it with a little vinegar or acid water, then add 0.5 kg of water, and evenly spray it onto 60 kg of concentrated feed with a sprayer, stirring while spraying. If conditions permit, it can be made into extruded feed for feeding, and the effect is even better.

What Does Green Fisheries Mean? Understanding the Concept and Connotations in One Article
Green fisheries encompasses three aspects of meaning. First, the coordination and consistency between fisheries production and the aquaculture environment, which is conducive to both fisheries development and a virtuous cycle of the ecological environment; second, fisheries inputs are safe and effective, with high input-output efficiency of materials and energy and little waste, and toxic and harmful substances below the standards legally stipulated by the state; third, fisheries outputs can meet the standards and requirements of human food consumption in terms of quantity and quality. Green fisheries is an extension of modern fisheries. In the overall development plan and structural adjustment of fisheries production, it highlights the concept of ecology, endowing

Detailed explanation of fish medication methods
Splash method: The splash method, also called the broadcast method, is the most commonly used method when using medication to prevent and treat fish diseases. Drugs that kill certain pathogens but are harmless to the fish themselves are broadcast throughout the fish pond to reach a certain concentration, so as to kill pathogens on the fish's body surface and gills as well as in the water, thereby curing or improving the condition. When using the splash method, you must first correctly measure the area and water depth of the fish pond, calculate the volume of pond water, then calculate the dosage, and evenly splash the drug into the fish pond in a certain manner

What are the new methods for preserving fish?
There is a new method for preserving fresh fish. The Moscow Research Institute of the Meat and Dairy Industry in Russia has developed a glycerin spray method to extend storage time, allowing stored fresh fish to retain its original flavor. The formula of this new glycerin spray technology is: glycerin 1%-20%, hydroxyethyl amide 0.15%-0.3%, sorbic acid 1%-5%, polyvinyl alcohol 0.3%-30%, with the remainder being water. Spraying this preservative onto fish can slow oxidation and achieve long-term preservation.

Key Technical Points and Precautions for Turtle-Fish Polyculture Explained
Turtle-fish polyculture is a method of turtle farming in which turtles are the main species and fish are stocked as a secondary crop. Experiments have shown that turtle-fish polyculture yields benefits 1 time or even several times higher than other polyculture methods. The following briefly describes its zoological principles, farming methods, and so on. 1 Zoological principles of polyculture. Turtle-fish polyculture refers to the mixed farming of turtles and fish in the same pond water body. From a zoological perspective, turtle-fish polyculture not only makes full use of the biological cycle of the water body, but also maintains the dynamic balance of the water body ecosystem. Turtles and fish can not only coexist,

Several commonly used green and environmentally friendly fishery drugs in aquaculture
Quicklime, table salt, and the like are not dedicated fishery drugs, but they are highly effective for preventing and treating aquatic diseases, pose no threat to the environment, and leave no drug residue problems. Quicklime: Regularly splashing quicklime into aquaculture water bodies can not only reduce the occurrence of many diseases, but also provide the calcium element essential for cultured organisms, which is especially important for crustacean aquaculture. Method of use: Choose quicklime that has not weathered; for pond clearing and disinfection, use 150-200 kg per mu; for disease prevention and treatment, generally 5-9, use once about every 20 days
