Using baits to prevent fish diseases is a commonly used method. The bait prevention and treatment of fish diseases has the advantages of convenient use, low cost, less drug concentration, and good control effect. However, there are also many fish farming households who improperly formulate the bait, which not only fails to prevent fish diseases, but also causes fishery medicines to be wasted and delay fish disease prevention. The preparation and use of baits should be based on different cultured fish. 1, solid type baits. This type of bait is suitable for feeding fish such as mackerel, squid, tilapia, and squid that devour commercial feed. When making such a bait, a certain amount of medicine and feed (such as bean cake, rapeseed cake, fish meal, rice bran, barley flour, etc.) are mixed, crushed and sieved, and then evenly mixed with the binder (flour, sweet potato flour, etc.) Mix, add water and mix well, then according to the size of the fish, use a feed machine or hand-made round or short cylindrical pellet feed, feed directly or dried and fed. 2, powder type baits. This type of bait can be used for filter-feeding fish such as salmon and squid. The drug and buoyant commercial feeds such as rice bran, bran, etc. are uniformly stirred and sprinkled on the surface of the water. The feeding time is preferably at noon. When cages fish feed baits, plastic films can be placed around the inside of the cage to prevent the baits from floating out of the cage. 3, adhesive type baits. This type of bait can be used for herbivorous fish such as grass carp and salmon. Choose fish-loving tender grass, according to the size of the fish, cut the grass into small pieces, use flour, sweet potato flour, rice porridge, etc. as a binder, first with hot water into a paste, after cooling the required drugs will be added Stir it evenly, stick it to the forage, dry it and feed it directly. 4, live type medicine bait. Some special fish such as squid, astragalus, squid, etc. only feed on live or semi-living feeds. Therefore, in the prevention and treatment of diseases, drugs can be mixed with appropriate amounts of binders, transferred into a paste with water, and then glued with live baits. Drugs, dried and fed. Carps only feed on live feed fish, but they can feed the fish with a larger dose of bait, and then feed the carp with a bait that has taken baits. When the carp is large, the drug can also be injected into the feed fish and immediately transferred to the carp pond. Astragalus and squid can feed live fish and can also eat dead fish. In addition to using live baits, drugs and binders can be mixed and then mixed with fish, clams, and snail meat.
