Problems solved by technology

[0003] As long-snouted squid is a relatively sensitive fish with strong stress and is sensitive to feed and environment, especially in the juvenile stage, the choice of feed for long-snouted squid fry is very important. During the fish period, it is mainly the development and function of the various organs of the fish body, so the nutrition is very strict. Since the current artificial compound feed is mainly based on a rough ratio of nutrient sources such as protein, fat, and vitamins, but this combination It is often neglected at this time that the organ development needs of the long-snout squid, that is, the nutritional system of most artificial compound feeds cannot meet the nutritional needs of the critical development of the long-snout squid juvenile stage, and because the long-snout squid is highly stressful, it is difficult for The palatability requirements of the initial feed are also relatively high

Abstract

The invention discloses a special starter feed for juvenile leiocassis longirostris and a preparation method thereof. The method provides a comprehensive and sufficient supplement for the organ development of juvenile fish by selecting natural animal meat bait; at the same time, the natural meat bait is a good attractant and very effective in promoting the early feeding of juvenile leiocassis longirostris; the meat material is more conducive to the digestion and absorption of juvenile fish because of beating treatment; by plant additives, the antioxidant and mildew-proof effects of feed can beachieved, the side effects of synthetic antioxidants and mildew-proof agents on juvenile leiocassis longirostris are avoided, and at the same time, harmful bacteria can also be inhibited.

Description

technical field [0001] The invention relates to the field of breeding technology, in particular to a special opening feed for juvenile long-snout catfish and a preparation method thereof. Background technique [0002] Commonly known as Jiangtuan, catfish, squid fish, and fat lump, long-snout squid belongs to the genus of ray-finned fishes, Siluriformes, and is an important economic fish in my country. In recent years, the artificial breeding of long-snout catfish has risen rapidly in Hubei, Sichuan, Chongqing, Guangdong, Anhui and other places in my country. Due to the considerable economic benefits brought by its good meat quality, it has been invested and favored by the majority of aquaculture farmers. . [0003] As long-snouted squid is a relatively sensitive fish with strong stress and is sensitive to feed and environment, especially in the juvenile stage, the choice of feed for long-snouted squid fry is very important. During the fish period, it is mainly the developme...
