At present, the aquaculture industry faces various challenges, and the environment, disease, quality and safety all warn the farmers. The new "Environmental Protection Law", which was implemented in 2015, strictly restricted the cultivation and sewage discharge. The Ministry of Agriculture and Rural Affairs (formerly the Ministry of Agriculture) pointed out that the direction of China's fisheries development is to reduce the amount of income, or to indicate that the aquaculture industry is time to transform. At the 2018 fish and shrimp polyculture technology exchange meeting, Dr. Zhu Changbo from the South China Sea Fisheries Research Institute proposed that ecological farming is the way out for the aquaculture industry. Zhu Changbo said that although low-salt shrimp farming has become the mainstream of shrimp farming in China, it still faces many difficulties, such as frequent diseases, risks and benefits are not proportional, and the breeding environment is deteriorating. After discussing solutions to these problems, "Positioning" is the best answer. He introduced several polyculture models of shrimp fish in low-salt ponds for farmers' reference. Why is the tilapia mixed with prawn in the shrimp pond? Read More »
The things you must know about water mildew are in the high season of water mildew, especially when the water temperature is 8-18 °C. Therefore, water mold is a fish disease that needs to be prevented in spring and early winter. However, the occurrence of water mold has several characteristics. As long as you pay attention to prevention, you can achieve good prevention and treatment. 1. Water molds grow in fresh or brackish water all year round, and water mold is hardly likely to occur in seawater. The higher water temperature in summer and autumn is not conducive to the reproduction of water mold, which is why we choose to disinfect with salt water once the water mold occurs, and the incidence of water mildew in summer and autumn is very low. Second, the pathogen of water mold is a fungus rather than a bacterium. Therefore, when selecting a control drug, attention should be paid to the use of drugs that have a killing inhibitory effect on fungi instead of the commonly used bactericidal drugs. The main commonly used in aquatic products are povidone. Iodine, glutaraldehyde, salicylic acid, gallium thioether, etc., although malachite green has special effects, in addition to Read More »
The upscale fish culture of the upscale fish breeding: fried and delicious, the market price of 40 yuan / kg from the snake python commonly known as the squid, belonging to the subfamily, the snake genus. The individual is small, the body is slender, and the body length is 7-8 times higher than the body height. The meat content is high and the meat tastes delicious. The amino acid content in the muscle is 18.3%, and the umami amino acid accounts for 8.4%, accounting for about 8%. 46% of the content. It is a high-protein, high-quality umami economic fish. With the decline of wild resources, the market price of snakes is as high as 80-100 yuan/kg. Therefore, it is urgent to carry out artificial breeding and breeding of snakes, on the one hand to meet the needs of the market, on the other hand, to proliferate. Release and restore natural resources. The preliminary breeding results are reported as follows: Snakes 1. Pond preparation 1. Pond conditions: 1.3 mu of yellow mud bottom soil ponds that had previously been raised by mud, with a water depth of 1.2 m or more, can maintain micro-flowing water all year round. The pond water source is the upstream reservoir water, and the pH is 7. Read More »
