The cost of fish feed accounts for a large proportion of the coast produced by fish farmers.
Feed pellets are widely used in fish farming. Choosing only the right quality fish feed particles can improve feed utilization, growth rate and immune system, and prevent disease. Therefore, fish farmers must learn how to choose the right fish feed pellets.
First, the nutrition of fish feed. The basic nutritional requirements of fish are protein, fat, carbohydrates, vitamins and minerals, etc., so fish feed must contain these substances. Some breeders believe that the higher the protein content, the better the feed particles. In fact, this is wrong, feed particle quality should consider not only the protein content, but also the proportion of other nutrients. A balanced diet is ideal for the normal growth of fish. Feed pellets use various grains such as wheat, corn, and beans as feed materials to add protein, fish meal, minerals, and other liquid nutrients. So it can meet the nutritional needs of fish.
Second, the appearance of feed pellets. High quality feed particles have a smooth surface and the same particle diameter. The particle size of the fish feed should take into account the mouth diameter of the fish, not too large or too small. Feed particles should be twice the diameter to increase feed intake and reduce feed waste.
Third, the stability of water. Fish intake is slow, so feed particles must be kept in water for a long time. Before buying fish feed pellets, fish farmers can take samples and place them in water to test their stability.
Fourth, reliable feed pellet manufacturing. Large scale, good reputation of the company's strong technical force to ensure balanced nutrition, scientific feed formula. Fish farmers should buy feed pellets from reliable manufacturers.
Fifth, the manufacture date of feed pellets. Feed particles that exceed their shelf life can reduce nutrient content and have adverse effects on fish. Fish breeders should ensure that feed pellets are available within production dates.

Appropriate Size and Type Feed for Fish Feeding
It is not economical to feed large fish with small particles. Also, feeding small fish or shrimp with large pellets can cause swallowing problems. For example, 8 mm feed pellets are recommended when feeding adult grass carp.
In addition to particle size, we should also pay attention to feed particle type. There are hard feed particles, soft feed particles and extruded feed particles. The first two are for sinking fish and the third is for floating fish. Once in the water, the hard and soft feed particles sink for a short time, which is suitable for feeding fish that live at the bottom of the pond, while the extruded feed can float or slowly sink.
Choosing the wrong size or type of feed will not only increase feed waste, affect fish health, but also cause water pollution. Therefore, it is very important to choose the right fish feed production machine to make the most suitable fish feed size and type.
