How to choose freshwater culture species
1. Market demand. Adapting to market demand is the fundamental basis for determining the type of culture. The first is to select popular varieties with moderate market prices, which are acceptable to most consumers, and that require large quantities, such as squid, squid, squid, and squid. The second is to select varieties with good meat quality, delicious taste, and less meat and thorns, such as squid, herring, group head lice, and California squid. The third is to select breeds that can meet a variety of needs, such as Koi, freshwater and whitefish, which have both food value and ornamental value, and can be processed with value-added krill crawfish, squid, astragalus, grass carp, etc., and have medicinal value. The variety. The fourth is to choose the best-selling varieties in the international market, which have the potential to export foreign exchange, such as tilapia and squid. 2. Water adaptability. On the one hand, farmed fish have higher requirements for water sources, water quality, lighting, etc., especially for dissolved oxygen. Therefore, in regions with abundant water resources, adequate dissolved oxygen, and good water quality, they may choose to be intolerant to hypoxia and have higher water quality requirements. Valuable species for breeding, such as large-size shrimp, crab, squid and so on. In water-scarce regions, when selecting varieties, we must choose varieties with strong adaptability to hypoxia, such as yellow peony root, black peony, tilapia, loach, crayfish crayfish and so on. In addition, fish have higher requirements for the salinity of water bodies, most species only adapt to very low salinity, but tilapia, Macrobrachium rosenbergii, freshwater white pelagic and other varieties are widely salty, when breeding these species Note the choice. 3. Feed availability. There are differences in the bait conditions that can be provided by different regions, and the species must be selected based on local conditions. Aquaculture of aquatic products can be broadly divided into the following food habits: zooplankton feeding, such as carp, carp, etc.; herbivorous, such as grass carp, carp, bream, etc.; zoobenthos feeding, such as herring, carp, river crab Etc.; omnivorous, such as leather beard, tilapia, carp, etc.; carnivorous, such as carp, California carp and so on. Should be based on the above-mentioned several major food habits, combined with local sources of feed selection of the appropriate breed. 4. Polyculture rationality. According to the conditions of breeding waters and the source of seedlings, different types of food and different active water layers were selected to conduct rational polyculture. At present, there are many models of polyculture, such as the polyculture of conventional fish and famous breeds, the polyculture of herbivorous fish and fish, the polyculture of carnivorous fish and omnivorous fish, and the development of shrimp and Macrobrachium rosenbergii. Rotation, fish, shrimp, crab polyculture and so on. When choosing a polyculture model, they should be selected based on the habitat, food habits, and the different types of interest they inhabit. For a species, does not affect or is conducive to the growth of existing species, is conducive to the entire polyculture mode of high yield and high efficiency, that is, optional support, or can not choose to support. 5. Strength suitability. Including two aspects: First, economic strength. With good economic foundation, there is a certain number of special breeds with the ability to take risks, such as pufferfish and valuable ornamental fish. If the economic foundation is weak and the risk is not strong enough, you can choose a breed with low investment and fast cash flow. Such as conventional fish, shrimp and so on. The second is technical strength. In the market where there are few supplies and high selling prices, it is often necessary to have a relatively high level of aquaculture technology when selecting and raising fish. For example, when feeding carnivorous fish, it is necessary to solve the problem of bait. It is necessary to raise the temperature and raise the temperature of breeding fish with narrow temperature. , The valuable fish must do a good job of dissolved oxygen and disease prevention. Farmers with immature technology must be raised from popular varieties, and breeding of famous and new varieties can only be done after accumulated experience.
