Novel microgranular feed for holothurian

Abstract

The invention relates to a novel microgranular feed for holothurian, comprising a basal feed formed by mixing fish meal, soya bean meal, sea mud, yeasts and vitamin premixes. The novel microgranular feed is characterized by being prepared through the following steps of: adding seaweed meal, sargassun thunbergii meal and algae meal to the basal feed, and then grinding to 200 meshes; adding water, and uniformly mixing; adding carboxymethyl celluloses and wheat glutens for coating at a temperature of 55 DEG C; carrying out vacuum drying, and then grinding stage by stage to manufacture granules with different granule diameters. The novel microgranular feed is uniformly dispersed in water, slowly dissolves out the nutrient components and has low sedimentation velocity and better withdrawing and retaining time in the water without polluting water.

Description

technical field [0001] The invention belongs to the field of aquatic feed, and in particular relates to a novel microparticle feed for sea cucumbers. Background technique [0002] Sea cucumber is a recognized seafood with great nutritional value and medicinal value, which is rich in protein, mucopolysaccharide and various active substances. With the in-depth development of sea cucumber resources, the demand for sea cucumber consumption has increased sharply, resulting in the overcapture of sea cucumber natural resources and a sharp decline in the population of sea cucumbers worldwide, and artificial breeding of sea cucumbers has emerged. 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. Sea cucumber seedlings have become a key link in the sea cucumber industry. Sea cucumber seedlings are mostly ground from natura...

Problems solved by technology

Because the growth of seaweed is easily affected by the external environment, the output is extremely unstable. When the output is large, the supply exceeds demand, resulting in waste, and when the output is small, it cannot meet the production needs, which seriously affects the sustainable development of the sea cucumber breeding industry. Therefore, artificial compound feed is gradually being used. In the production of sea cucumber seedlings

[0003] At present, the common commercial sea cucumber feeds are mostly in the form of powder or coarse particles. The former will quickly disperse after being put into the water body, which will cause serious loss of nutrients and easily pollute the water quality, resulting in turbidity of the water body; In general, sea cucumbers are not easy to eat, and the accumulated feed is soaked in seawater and then dissolved, resulting in local eutrophication of the water body, which in turn leads to poor water quality.

In response to this situation, many people have improved sea cucumber feed, but most of them just changed the feed formulation into fine particles, etc., and did not fundamentally solve the problems of nutrient loss and water pollution.
