Chinese scholars led in "Nature" and the freshwater breeding was ignored

Aquatic products and aquaculture provide indispensable nutritional support for human beings.

So, aquaculture depends on land or ocean? At present, half of the world’s aquaculture comes from aquaculture, and aquaculture is divided into seawater breeding and freshwater aquaculture. In the current research, seawater breeding has attracted the attention of most scholars around the world, and freshwater farming is largely ignored.

In response to this phenomenon, Dr. Zhang Wenbo, Shanghai Ocean University with a number of global top scientists, conducted a systematic research that the importance of freshwater aquaculture in global aquatic products is far greater than seawater breeding. At zero yesterday, Beijing time, "Nature" magazine published this research results online.

The article is led by Shanghai Ocean University, the University of Stirling University, Michigan State University in the United Kingdom, the World Fisheries Center, the Asian Institute of Technology, the Royal Academy of Sciences, and the Stockholm Capital Center and other units. Not the ocean. "

Studies believe that sea aquaculture has received excessive attention in the agenda of global aquaculture, and the importance and potential of freshwater breeding has been ignored. One of the main manifestations is that the publication in the seawater breeding field has been published several times more than freshwater aquaculture. Based on the edible output meter, freshwater aquaculture has contributed 77%of farming aquaculture products worldwide. About 80%depend on bait feeding farming fish produced in fresh water.

Even in the types of breeding that do not rely on bait, the edible yield of filter -feed fish with global freshwater aquaculture is higher than the filter -eating shellfish production of seawater breeding.

The category is mainly cultivated in salty freshwater ponds on the coastal land, and its proportion of freshwater farming increases year by year.

Studies have proposed that freshwater farming has contributed greater contributions to global food security. Compared with seawater breeding, it has comparative advantages in large -scale production and affordable aquatic products. The reason is that the freshwater farming fish is mostly low -nutritional filtering and omnivorous fish. Its artificial reproduction is difficult and has strong adaptability to low -soluble oxygen and nutrients. Breeding production. When talking about the future development trend of global aquaculture, Zhang Wenbo said: "In the past 20 years, the consumption of aquatic products in developed countries has basically maintained stable, and the consumption of aquatic products in developing countries has increased rapidly. To better meet the future global scope, especially developing countries, the growing demand for aquatic products. "To this end, this study can provide a basis for policy formulation for global aquaculture development. The importance, arguments, and conclusions of this study have been highly evaluated by the reviewer of Nature. The reviewer agrees that the current seawater breeding has attracted most of the world’s attention, funds and human resources. It is believed that this study helps to transfer people’s attention from the ocean to land. (Xu Ruizhe).
