To raise the breeding efficiency, it is recommended to actively adjust the structure of the species and raise the following types of aquatic products: To breed fish-eating species: In the same pond, properly carve some carnivorous fish, such as squid, blackfish (blackfish), California salmon and squid use these fish to remove small, miscellaneous wild fish that are of low economic value in the pond, transform them into high-quality aquatic products, and reduce competition for food and competition for the fish. Increase the production of farmed fish. Generally, 10-30 tails of carnivorous fish can be set up per mu of water. It should be noted that carnivorous fish are smaller in size than the main fish in order to protect the safety of the fish. The chiefly cold-culturing species are tropical fish and shrimp, such as tilapia, freshwater whitefish, brazilian cod, and Macrobrachium rosenbergii, Penaeus vannamei, etc. These breeds have good flesh quality and bright colors, and can be used as fishing targets. The requirements for farming conditions are not high, and they can be either monocultured or polycultured, with short breeding cycles and quick results. The long-legged breeds of the polyculture include polyculture with turtles, turtles, river crabs, green prawns, bullfrogs, and American frogs. It can be fish-based, and it can also be fish, crab, shrimp, etc. If fish is the main species, dozens of turtles are mixed in each acre, and a small amount of fish in the pond is used to supplement some feed. It is easy to produce 10-20 kg of turtles per mu. Intensive breeding of "unfinished" varieties: that is, the introduction of breeding fish, such as Xiangyun, Xiangyun and Other triploid fish. Because these fish can not breed offspring, they have the advantages of fast growth, tender meat, and beautiful taste, and they can feed at lower temperatures (5 degrees Celsius), relatively prolonging the growth period and yielding higher yields. Holding "small breeds" temporarily: such as loach, yellow peony, etc., have long been considered as "small breeds" with small specifications and low yields. These small varieties are gradually favored by consumers because of their delicious taste and rich nutrition. The price has been relatively stable for many years. It is possible to use spring to buy smaller-sized scallions and loach and implement intensive feeding. After a few months, after the listing, not only can we achieve larger specifications, but at the same time, the market price will be greatly improved.
Introduction: This Grain Huller can hull multi grains. such as: millet ,sorghum, maize ,wheat ,barley ,oats ,soybeans , etc. The grains and husks can be separately completely by air flow. It suitable for all kinds of grain processing factories, especially for family owned , small or medium size factories in rural areas.
