A wide variety of aquatic feed, from the shape, can be divided into powder feed, soft pellet feed, hard pellet feed and extruded feed; distinguish from the use, mainly squid feed, shrimp feed, turtle feed 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€. First of all, to determine the type of feed and to look at the quality of the feed, it is necessary to select feed products produced by companies with good reputation and large scale. Because of their relatively strong capital and technical strength, it is possible to guarantee the balanced nutrition and formula science of the feed produced. For example, there is a feed specifically designed for squid, and there is a feed specially designed for grass carp. This is highly targeted; when buying aquatic feed, don’t neglect the label on the feed package. The feed tag is generally at the upper left corner of the feed package. The important contents such as the product name, nutrient content, production period, shelf life, etc., are specified, especially the instructions for use. Therefore, the packaging must be carefully read when purchasing. Secondly, attention should be paid to the selection of particle size. If there are doubts, consult the distributors clearly and avoid losses due to improper use. Particular emphasis is placed on the size of the particle size when purchasing aquafeeds. Aquaculture feeds have particle sizes ranging from 0.5 to 8.0 mm, and are fed with different oral water products. Basically, the particle size of the feed should be 2/3 of the longitudinal length of the split mouth of aquatic products. For example, if the longitudinal length of the mouth crack is 9 mm, then it is suitable for feeds with a grain size of 6 mm. This will neither cause waste nor affect food intake. To determine the quality of aquafeeds, we must also look at how they look. For example, to identify whether they are good feeds from the aspect of color, there should be brighter luster and consistent color. This is the first sensory indicator to select feeds; Select moldy or deteriorating feeds. Moldy or deteriorating feeds are usually blue in color and very uneven. Inconsistent, this 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. In addition, quality can be identified from the smell of feed. Aquatic feeds, due to the use of some fishmeal, generally have a normal fishy smell and are pleasant to smell. 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. Finally, look at stability. When purchasing aquafeeds, you may wish to take a little less and soak in the water for a while to see how stable it is in the water and to see if the feed is good or bad. It is hoped that aquaculture farmers will be able to purchase good feeds with high quality and low price through the above methods.
