The invention discloses seaweed 
meal with an 
adhesive effect for an aquatic feed. The seaweed 
meal comprises the following raw materials in parts by weight: 5-15 parts of enteromorpha, 0-15 parts of ulva, 25-45 parts of 
kelp, 15-30 parts of 
undaria pinnatifida, 5-15 parts of gulfweed, 5-20 parts of laver, and 15-20 parts of 
gracilaria. A preparation method of the seaweed 
meal comprises the following steps of mixing seaweed in proportion; performing 
grinding and enzymolysis to obtain processed seaweed; adding the processed seaweed in a carrier; mixing the processed seaweed with the carrier to obtain a mixture; 
drying the mixture; and crushing the dried mixture. The seaweed meal is prepared from natural 
algae, so that the seaweed meal is high in 
adhesive effect, the stability of bait in water can be enhanced, and the 
powder yielding rate during 
processing can be reduced; compared with terrestrial plants, the seaweed meal contains mineral elements of 
iodine, 
calcium, 
phosphorus and the like, and contains various vitamins, 
algal polysaccharides, 
mannitol and the like, and after enzymolysis, the seaweed meal is easy to absorb and utilize by animals, so that the feed efficiency can be effectively improved, the growth and the development of animals can be promoted, and the 
disease resisting ability of animal bodies is increased; and the seaweed meal contains unique fishy smell substances and 
pigment of the seaweed, so that the food-calling properties of the feed can be increased, the body color of cultured fish can be close to natural body color, and the 
economic benefits of cultivation products are increased.
