Problems solved by technology

At present, there have been some studies on the requirements of flounder for protein, fat (including essential fatty acids), vitamins, and trace elements, but high-efficiency and high-quality artificial compound feeds have not yet been developed, and most farmers still use small miscellaneous fish (some have added some eel feed), the residual bait seriously pollutes the water quality, and the hazards of fish diseases increase significantly, which affects the development of the flounder aquaculture industry and the improvement of economic benefits

Abstract

The invention discloses a high-efficiency and environmentally-friendly compound feed for paralichthys olivaceus and a preparation method thereof. According to a formula, the feed comprises the following components: fish meal, alpha-starch, beer yeast, extruded soybean, soybean lecithin, soybean meal, fish oil, camitine, glycine betaine, choline chloride, calcium biphosphate, enzyme preparation and various vitamins and mineral salts. The preparation method comprises the following steps of: weighing the materials in proportion; uniformly mixing the materials and then crushing the mixture to ensure that 98 percent of the raw materials pass through a test sieve with meshes of 0.25mm; adding the alpha-starch, the carnitine, the enzyme preparation and various vitamins and mineral salts into the obtained product in proportion and uniformly mixing the mixture again; adding the fish oil and water in an amount which is 45 percent of the total weight of each component of the feed for the paralichthys olivaceus according to the formula into the mixture and uniformly stirring the mixture; and pelletizing and molding the mixture with a soft granulator. The compound feed prepared by the method and meeting the growth characteristics of the paralichthys olivaceus has the advantages of improving the feed digestibility, the survival rate and the growth speed of the paralichthys olivaceus, reducing pollution on sea area and protecting marine ecological environment.

Description

technical field [0001] The invention belongs to the field of aquatic feed, and in particular relates to a high-efficiency and environment-friendly compound feed for flounder and a preparation method thereof. Background technique [0002] Flounder ( Paralichthys olivaceus ) is a cold-temperate benthic carnivorous economic fish with delicious taste, tender meat and high economic value. . At present, there have been some studies on the requirements of flounder for protein, fat (including essential fatty acids), vitamins, and trace elements, but high-efficiency and high-quality artificial compound feeds have not yet been developed, and most farmers still use small miscellaneous fish (some have added some eel feed), the residual bait seriously pollutes the water quality, and the hazards of fish diseases increase significantly, which affects the development of the flounder aquaculture industry and the improvement of economic benefits. With the expansion of the breeding scale of...
