First, determine the type of feed A wide variety of aquatic feeds are available on the market. They can be divided into powdered feeds, soft pellet feeds, hard pellet feeds, and puffed feeds. According to the purpose of use, there are salmon, shrimp, turtle and so on. In order to select quality and cheap food among a large number of aquafeeds, it is necessary to specify what kind of material to buy and “to fish the fishâ€. If you are raising squid, you should buy squid material instead of using other materials, and you must also see whether it is broodstock or adult fish. Second, the difference in quality 1, the choice of credibility. To select feed products produced by companies with good reputation and large scale, they have relatively abundant funds and technical strength, can guarantee the balanced nutrition of feeds produced, scientific formulas, and can be targeted, for example, there are feeds specifically designed for squid. There is a feed specifically designed for grass carp that is highly targeted. 2, packaging options. When buying aquatic feed, don't neglect the label on the feed package. The feed label is generally at the upper left corner of the feed packaging, with the important contents such as the product name, nutrient composition, production period, and shelf life, respectively, and in particular instructions for use. So read it carefully when you buy it. 3, particle size selection. If you have any doubts, consult the distributors clearly to avoid losses due to improper use. Particular emphasis is placed on the size of the particle size when purchasing aquafeeds. Aquatic feeds have particle sizes ranging from 0.5 to 8.0 mm and are fed separately with different mouthwatering aquatic products. Basically, the particle size of the feed should be 2/3 of the longitudinal length of the split mouth of aquatic products. Take the head lice, for example, if the vertical length of the crack is 9 mm, then it is suitable for feeding feeds with a particle size of 6 mm, which will neither cause waste nor affect food intake. If you want to judge the quality of aquafeeds, you have to look at how they look. 4, can not choose to produce mildew or deterioration of feed. Mild or deteriorating feeds are generally blue in colour and very uneven and inconsistent. This kind of feed should not be selected. Especially during the preservation process, due to the relatively humid weather in the south, it is easy to mold. Therefore, it is necessary to be careful when selecting feedstuffs, and it is generally not necessary to choose such a deteriorating feed. In addition to not selecting mildewed feed, sticky feeds should not be selected because of moisture, etc., which causes the feed to stick, and some nutrients may change after bonding. 5, the appearance of choice. The quality of the feed can be judged by its appearance, and the quality of the feed can be recognized by the smell of the feed. From the odor on the identification of good feed, especially aquatic feed, because of the use of some fish meal, generally have a normal fishy smell, smell more pleasant. If it is a poor feed, because it uses some substitutes for fishmeal, the fishy smell is lighter, or simply not. In addition, bad feeds may have a musty smell or “hayâ€, which is actually the taste produced after the oxidation of fat. This feed should not be fed because once the feed is fed, it may cause fish. A large area of ​​death. 6, stability choices. When buying aquafeeds, you may wish to take a little less and soak it in water for a while to see how stable it is in the water. Through stability, you can also see the quality of the feed. 7, color selection from the color to identify good feed: there should be a relatively bright luster and color is the same, which is the first sensory index of the choice of feed.
