When the new concept of polyculture refers to polyculture, people immediately think of the polyculture of the four major fishes, and there seems to be no other polyculture model beyond that. In fact, the concept of scientific polyculture is very rich in content. The purpose of polyculture is to: (1) make full use of limited water space; (2) rationally arrange the food chain among various biological groups; (3) reduce the spread of diseases Opportunities; (4) Improve Integrated Aquaculture Production; (5) Improve Integrated Farming Benefits. From these perspectives, we can boldly design a brand new polyculture model. Even fish, shrimp, clams, and crabs can be properly paired with polyculture. In fact, some farmers have begun to do this work, such as mixed turtles in carp ponds, turtles can eat the remaining scraps of carp, timely feeding of dead fish, effectively cut off the spread of pathogens.
Dilution domestication Many aquaculture species are widely salty, such as Penaeus vannamei can even survive in very low salinity freshwater bodies. Mariculture species cultivated in freshwater tend to grow faster and the disease can be greatly reduced. From a long-term point of view, marine aquaculture species are destined for domestication and have broad prospects for development.
Hybrid Advantage An excellent hybrid breed has its advantages that are indisputable, especially in terms of growth rate, disease resistance, and adaptability to the environment.
Imitation of wild-breeding With the improvement of living standards, people have higher and higher requirements for the quality of aquatic products, which leads to the same aquaculture species, the wild price is higher than artificial breeding many times, this phenomenon can not be ignored Caused aquaculture community deep thinking. Some people set turtles across the year in four ponds. The quality of turtles raised is very close to that of wild turtles. Their price is not cheap, and they have achieved very good economic benefits. We can use this example as an example to fully exploit the enormous potential of this farming model.
The large-scale farming of our common aquaculture species can often surprise market prices if they are raised to oversized specifications. Of course, this unusual breeding mode needs to be based on certain funds and other supporting conditions, and there must be accurate market analysis and judgment capabilities in the selection of varieties, but in general it can be a new road of profitability.
Rotation in aquaculture, rotation has not been given due attention. There are at least three major benefits of rotation: First, to reduce the deterioration of pond sediment; Second, to reduce the chance of disease transmission; Third, according to market conditions, flexible choice of aquaculture species. Nowadays, new breeds emerge in an endless stream, which gives farmers a great deal of convenience in choosing a new breeding mode. The question of rotation is even more important and necessary. For example, some fish farmers breed P. vannamei in the first half of the same pond and fish reared in the second half of the year. This is very effective in preventing and controlling diseases.
