With the bait, according to the nutritional needs of different types of fish at different stages of growth, a number of nutrients with complementary functions are blended in a certain proportion to prepare foods that can meet the needs of fish growth and reproduction and have higher economic benefits. With the bait has a comprehensive nutrition, good palatability, bait rewards and other advantages. According to the different forms, the matching bait can be divided into: (1) Powdery bait is prepared by mixing powdered raw materials that have been crushed to a certain size by a certain proportion. Such as carp bait is to add water in proportion to the powdered bait, add oil, and then fully stirred to form a strong sticky and elastic group of bait, feeding. The fry can be cultured using a 600-μm diameter screened powdered bait that enters the body of water and is suspended in favor of feeding on the fry. (2) The granular bait pellets are short sticks. The diameter of the particles, depending on the size of the fish. The general particle diet has a diameter of 2 to 8 mm and a length of 1 to 2 times the diameter. According to the processing method and the nature of the finished product, the granular bait is divided into three types: soft pellet bait, hard pellet bait, and puffed bait (or foamed bait). 1 Hard pellet bait: bait material with a water content below 13% after processing and cooling the hard pellet bait. The processing of this bait is characterized by the continuous smashing, stirring, mixing, granulation and forming of the raw materials until the cooling and the like. Hard grain bait is widely used for the cultivation of fish such as herring, grass carp, squid, bream, tilapia and rainbow trout. Hard grain bait particle diameter should generally be 4 ~ 8 mm, cultured fish body weight used by the grain bait slightly larger diameter, smaller body weight used pellet bait diameter is slightly smaller. Hard grain bait should have good stability in water, enter the water for 10 minutes, the loss weight should not exceed 10%. 2 Soft pellet bait: Soft pellet bait means a bait material with a water content of 25% to 30% and a relatively soft texture produced by a meat grinder granulator. This bait is suitable for fish such as breams, grass carp, trout and rainbow trout. Soft pellet foods are submerged pellets. The disadvantage is poor water stability. 3 Puffed bait: Extruded bait is a kind of bait material that is mixed with powdery raw material in the form of steam after being fully mixed, and then decompressed immediately after high-temperature and high-pressure treatment to rapidly expand the bait volume. The starch contained in this bait is gelatinized at high temperature to form foamed particles with loose structure and firm particles. This granular diet is suitable for rearing ornamental fish, grass carp, and head lice. (3) Fine-grained bait The micro-grained bait is a food blend developed by Japan and used for rearing shrimp, shellfish seedlings, and fish seedlings. It can also be used to feed filter-feeding fish. China currently uses particulate feeds during shrimp breeding. The processing conditions of the micro-particle bait are relatively high. Generally, the size of the pellets is in the range of 10 to 100 micrometers. According to different manufacturing methods and properties, the micro-encapsulated bait material can be divided into three types, ie micro-film bait (MCD), micro-mud bait (MBD) and micro-capsule bait.
