Feed used for sea cucumber and preparation method thereof

Abstract

The invention relates to feed used for sea cucumber and a preparation method thereof. With sargassum thunbergii, gulfweed, kelp powder and bean pulp being basic raw materials, micro-ecological preparations are added for fermentation, then sea cucumber premix is added, and then the fermentation feed used for the sea cucumber is prepared. The fermentation feed is prepared from, by mass, the basic raw materials of 10-14% of sargassum thunbergii, 10-14% of gulfweed, 50-60% of kelp powder and 15-20% of bean pulp. The micro-ecological preparations are formed by mixing bacillus subtilis, candida utilis and trichoderma viride according to the proportion of 5-7:1-2:1-2, and the quantity of the added micro-ecological preparations accounts for 5-10% of the basic feed, and the sea cucumber premix accounts for 1-2% of the basic feed. The fermentation feed used for the sea cucumber has full aroma, has rich monosaccharide, disaccharide, amino acid, peptides and other micro-molecule nutrient substances and active probiotics easy to digest and absorb by the sea cucumber, increases the digestion and absorption rate of the feed for the sea cucumber, avoids waste of kelp biological resources and is provided as low-price and high-quality feed for the sea cucumber in the sea cucumber culture industry.

Description

technical field [0001] The invention belongs to the technical field of aquaculture animal feed, and particularly relates to a sea cucumber feed and a preparation method thereof. Background technique [0002] Sea cucumber, some people call it "sea ginseng", is named after the tonic effect similar to ginseng. There are dozens of kinds of sea cucumbers in the world, and there are more than 20 kinds in my country. With the expansion of large-scale sea cucumber farming in recent years, the problem of sea cucumber feed and nutrition has become a bottleneck for the development of sea cucumber farming. Sea cucumbers are low-grade invertebrates with weak digestion and absorption functions, which not only reduces the nutritional value of feed, but also causes pollution of aquaculture water. [0003] And kelp is one of the four major seaweed aquaculture products in my country, providing a strong raw material base support for the brown algae industry. In industrialized kelp productio...

Problems solved by technology

However, due to the low protein content of crude kelp powder itself, it cannot meet the growth needs of sea cucumbers and the low activity of alginate enzymes in the intestinal tract of sea cucumbers cannot digest and absorb the nutrients in kelp powder rich in alginic acid, so crude kelp powder It can only be added to sea cucumber feed in a small amount as a feed additive
