Can hairtail fish be farmed in captivity?This is a problem that has long plagued the fishing community. With the progress of science and technology and the development of fishery technology, the artificial breeding of hairtail has gradually become a hot topic of research. This article will focus on whether the hairtail can be artificially cultivated, the technical problems of aquaculture and the feasibility of artificial cultivation of hairtail.
1. The natural ecological habits of hairtail fish
Hairtail, also known as saury, waka, fat belt, oil belt, tooth ribbon, etc., belongs to the class of bony fishes, perciformes, and hairtails. Hairtail is a migratory fish, widely distributed in the coastal areas of China, with the highest yield in the Yellow Sea and Bohai Sea. Hairtail fish are clustered and swim to the shore in spring to breed and in autumn to the deep sea for wintering. Hairtail has strong adaptability to environmental factors such as water temperature, salinity, and food, and can survive in a variety of water environments.
Second, the technical problems of artificial breeding of hairtail fish
1.Breeding technology: The reproductive habits of hairtail fish are complex and need to be carried out under specific environmental conditions. At present, the technology of artificial reproduction of hairtail is not mature, and the problems of low reproduction rate and low survival rate of fry restrict the development of artificial hairtail culture.
2.Breeding environment: Hairtail fish has high requirements for the breeding environment, and needs to grow normally under certain water temperature, salinity, dissolved oxygen and other conditions. Artificial breeding of hairtail fish needs to simulate the natural ecological environment and establish a breeding pond suitable for the growth of hairtail, which has higher requirements for breeding technology and equipment.
3.Feed technology: The research and development of artificial feed for hairtail fish is still in its infancy, and there is no mature feed formula at present. The demand for feed is high, and if the feed formula is not reasonable, it will affect the growth rate and quality of hairtail.
3. Feasibility analysis of artificial breeding of hairtail fish
1.Technological progress: With the continuous development of science and technology, key technical problems such as artificial reproduction, breeding environment control, and feed research and development are expected to be solved. For example, gene editing technology can be used to improve the reproduction rate and survival rate of hairtail fish species; Using modern breeding equipment and technology, simulating the natural ecological environment, to provide suitable breeding conditions for hairtail fish.
2.Market demand: As a nutritious and delicious seafood, hairtail fish is deeply loved by consumers. With the improvement of people's living standards, the demand for high-quality hairtail fish is increasing. Artificially farmed hairtail fish is expected to meet market demand, alleviate resource pressure, and provide consumers with safer and more reliable food**.
3.Economic benefits: Artificially cultivated hairtail fish has high economic benefits. Compared with wild hairtail, artificially cultured hairtail has the advantages of fast growth rate, high yield and stable quality. Through large-scale farming, production costs can be reduced, economic benefits can be improved, and more benefits can be brought to fishermen and consumers.
Fourth, the development of artificial aquaculture of hairtail fish
1.Strengthen investment in scientific research: In view of the technical problems of artificial breeding of hairtail, scientific research investment should be strengthened, and in-depth research on the knowledge of reproduction, growth, disease and other aspects of hairtail fish should be deeply studied, so as to provide technical support for artificial breeding.
2.Establish demonstration bases: establish a number of artificial breeding demonstration bases for hairtail fish, apply advanced breeding technology, equipment and concepts to practice, and form a generalizable breeding model.
3.Improve the industrial chain: strengthen the construction of the artificial breeding industry chain of hairtail fish, including seed breeding, feed research and development, breeding technology, product processing and other links, form a complete industrial chain, and improve the overall efficiency of artificial breeding of hairtail.
4.Strengthen policy support: ** should increase the support for the artificial breeding industry of hairtail, including financial support, tax incentives, technical guidance, etc., to create favorable conditions for the development of the industry.
To sum up, the problem of artificial cultivation of hairtail fish is not an easy task, but through scientific and technological progress, market demand and policy support, the feasibility of artificial hairtail culture is gradually improving. We have reason to believe that in the near future, artificial aquaculture of hairtail fish will become an important part of the fishery industry, and make important contributions to the sustainable use of fishery resources and the development of fishery economy.
