What is green fishing?
Green fishery includes three meanings: first, the coordination of fishery production and aquaculture environment, which is not only conducive to fishery development, but also conducive to the virtuous circle of the ecological environment; second, fishery inputs are safe and effective, material and energy input and output efficiency is high, waste is less, toxic and harmful substances are lower than the national legal standards; third, fishery output can meet the requirements of human food consumption for quantity and quality.
Green fishery is the extension of modern fishery. In the overall development planning and structural adjustment of fishery production, the concept of ecology is highlighted and the traditional fishery is endowed with new contents and ideas.
-- in terms of farmed varieties, attention should be paid to the cultivation and development of disease-resistant, stress-resistant and high-quality farmed varieties, and efforts should be made to increase the quantity and output value of improved variety production in the whole fishery production.
-- optimize the allocation of resources to cultivate relatively few aquatic products and obtain several times the output value and profits produced by non-green fishery production, so as to achieve the business effect of saving resources and reducing waste emissions.
-- the application of a healthy culture model, reasonable collocation of varieties, moderate level of input and output, combination of cultivation and cultivation, and the best utilization of all kinds of resources through the recycling of wastes within the culture system.
-- minimize the production of wastes in the process of culture, and obtain the best environmental and ecological benefits while achieving ideal culture results and economic benefits.
-- adopt advanced technologies (such as water quality regulation technology, high-efficiency feed production and feed feeding technology, health management and disease prevention technology, rapid detection and whole-process monitoring technology) to give full play to the inherent potential of production, achieve the safety, health and sustainable development of fishery production, provide reliable green aquatic products for society, and improve the comprehensive production and social benefits of fisheries.

Methods of drug use in fish
Sprinkling method: sprinkling method, also known as sprinkling method, is the most commonly used method for the prevention and treatment of fish diseases with drugs. Drugs that can kill some pathogens but are harmless to the fish itself are sprinkled in the fish pond to reach a certain concentration to kill the pathogens on the body surface and Gill of the fish as well as in the water, so as to recover or improve the condition. In order to use the sprinkling method, we must first correctly measure the area and water depth of the fish pond, calculate the volume of the pond water, and then calculate the dosage, and sprinkle the medicine evenly into the fish pond in a certain form.
