1, milk flavor. Milk fragrance refers to the fragrance similar to that emitted by milk. Most of the smell of grandma comes from fat, and the fat globules in milk are emulsified in hydrocolloid protein, forming a pleasant smell of milk. The flavor of milk mainly comes from the volatile components in milk, among which dimethyl sulfide and butyrate are the main chemical components that produce milk flavor. Milk fragrance is more attractive to crucian carp in low temperature weather.

2. Gu Xiang. Ancient fragrance refers to the fragrance emitted by natural grains, and corn fragrance, wheat fragrance and potato fragrance can all be classified as ancient fragrance. Valley flavor is more attractive to freshwater fish such as carp and crucian carp in the season with slightly higher temperature. Ancient incense is also the most widely used fragrance type in bait.

3, fruity. Pineapple, peach, apple, citrus, strawberry, jujube, grape and other fruits are fruity, suitable for fishing fish of all sizes or older in high temperature weather. Generally speaking, the higher the temperature, the bigger the fish, the older they are, and the more they like to eat fruity food. For example, when fishing big carp, big herring and big grass carp, you can mix the bait with fruit flavor.

4. Compound fragrance. At present, the essence of many kinds of fishery additives (small fishery drugs) is compound. If it is a regular product, it needs the cooperation of ichthyologists and odorists in the fish laboratory to measure the favorite taste of a certain fish through experiments, and then scientifically mix it to prepare the product with the favorite taste of this fish. For example, Fuyuxiang series of fragrance spreaders, Jinding Wang Yao, Doba salt, fish safety factor, fish alpha, multi-green ring, crucian carp and so on are all compound fragrances prepared by scientific experiments in fish laboratories. Odor diffusion agent is a kind of water-based polymer, which has a strong attraction to most freshwater fish.
