Juvenile stichopus japonicus breeding feed and preparation method thereof

Abstract

The invention relates to a juvenile stichopus japonicus breeding feed and a preparation method thereof. The preparation method comprises: (1) carrying out ultrafine crushing on 5-10 parts of imported fish powder, 5-10 parts of mytilus edulis powder, 5-10 parts of shrimp powder, 8-10 parts of pachyrhizus erosus seedling, 20-40 parts of scagassum powder, 30-40 parts of sea mustard powder, and 0.5-1 part of choline chloride to achieve a particle size of 80-100 mesh; and (2) mixing various raw materials in the step (1), adding a proper amount of 60 DEG C hot water during the mixing, carrying out first aging after uniformly mixing, granulating, carrying out second aging after granulating, cooling, drying, and carrying out ultrafine crushing to obtain the finished product feed. According to the present invention, the prepared juvenile stichopus japonicus breeding feed has characteristics of balanced and complete nutrition and good palatability; after the juvenile stichopus japonicus is fed with the juvenile stichopus japonicus breeding feed, the development is good, the disease resistance is strong, the growth is rapid, the weight gain is high, the stichopus japonicus breeding period is substantially shortened, the stichopus japonicus breeding efficiency is substantially improved, and the yield per unit area is increased; and with the added choline chloride, the immunity and the disease resistance of the stichopus japonicus can be improved, and the survival rate can be improved.

Description

technical field [0001] The invention relates to the field of aquaculture feed, in particular to a young sea cucumber breeding feed and a preparation method thereof. Background technique [0002] Apostichopus japonicus belongs to a kind of temperate cold-water ginseng species. It has delicious taste, high nutritional value and medicinal value, and is highly sought after by the market. With the continuous increase of market demand, and because the growth of sea cucumber is limited by geographical distribution, the deterioration of marine environment and the impact of human overfishing, the output of natural sea cucumber in the past can no longer meet the demand, and people have to resort to artificial breeding To meet the growing consumption. In recent years, the scale of sea cucumber farming has been expanding day by day, and corresponding feed products have also emerged one after another. However, the existing commercially available sea cucumber feed products fundamentally...

Problems solved by technology

However, the existing commercially available sea cucumber feed products are fundamentally produced by rough processing of marine algae, with unreasonable ingredients and unbalanced nutrition

It has been found in farming practice that using the above-mentioned sea cucumber feed to feed sea cucumbers can easily lead to the emergence of diseases of sea cucumbers, and there is no specific formula for the nutritional needs of sea cucumbers in different stages of the growth cycle.
