Abstract

The invention discloses a micro particle feed for cultivating juvenile sea cucumber and a preparation method thereof, wherein the micro particle feed for cultivating juvenile sea cucumber can completely meet the needs for various nutrients of the juvenile sea cucumber for growth and solves a biological bait shortage problem during artificial sea cucumber breeding. The micro particle feed comprises the following components in percentage by weight: 15 to 20 percent of fish meal, 5 to 10 percent of bean pulp, 20 to 50 percent of sargassum thunbergii powder, 10 to 15 percent of sea mud, 5 to 20 percent of marine algae powder, 5 to 10 percent of yeast and 0.5 to 1 percent of vitamin premix. The preparation method comprises: mixing the fish meal, the beam pulp, the sargassum thunbergii powder, the sea mud, the marine algae powder, the yeast and the vitamin premix; coating a film with carboxymethylcellulose and wheat gluten, wherein the mass ratio of the carboxymethylcellulose to the wheat gluten is 1:1-3; and drying the mixture under vacuum and crushing the mixture into particles with a particle size ranging from 100 to 500mum.

Description

Technical field: [0001] The invention relates to a feed for artificially cultured juvenile sea cucumbers and a preparation method thereof, in particular to a feed for juvenile sea cucumbers that can completely meet the various nutritional needs of juvenile sea cucumbers and solve the problem of insufficient biological bait during artificial breeding of sea cucumbers. Microparticle feed and its preparation method. Background technique: [0002] At present, the development scale of the sea cucumber breeding industry has become larger and larger, and the annual output value of sea cucumbers in northern my country alone has reached tens of billions of yuan. Most of the existing sea cucumber seedlings are ground into a slurry of fresh benthic diatoms and large seaweeds that grow naturally, and are used as feed for juvenile ginseng in the growth period. Because the growth of seaweed is easily affected by the external environment, the output is extremely unstable. When the output ...
