Method for preparing sea cucumber compound feed with additional Enteromorpha

Abstract

The invention discloses a method for preparing sea cucumber compound feed with additional Enteromorpha. In the method, sea cucumber compound feed is added and mixed with dry Enteromorpha powder to form the sea cucumber compound feed with additional Enteromorpha, the coefficient of variation of the obtained sea cucumber compound feed with additional Enteromorpha after being fully mixed is less than or equal to 10 percent, and the obtained sea cucumber compound feed with additional Enteromorpha are made into grains with a diameter of 3 millimeters by using 2 percent sodium alginate as a binder. The added dry Enteromorpha powder accounts for 30 percent of the weight of the sea cucumber compound feed with additional Enteromorpha. The sea cucumber compound feed with additional Enteromorpha comprises the following ingredients by weight percentage: 10 percent of fish meal, 5 percent of Sargassum thunbergii powder, 20 percent of vinasse, 15 percent of sea mud, 10 percent of bean pulp, 30 percent of Enteromorpha powder, 8 percent of bran, 1 percent of vitamin mix and 1 percent of inorganic slat mix. In the sea cucumber compound feed with additional Enteromorpha prepared by the formulation, the Enteromorpha powder used to replace kelp powder can reduce the cost of feed prepared by the conventional formulation (not using the Enteromorpha powder) and avoids influencing the growth of Apostichopus japonicus Selenka; and the survival rate of the Apostichopus japonicus Selenka is improved remarkably (P is less than 0.05).

Description

Technical field: [0001] The invention belongs to the preparation technology of sea cucumber compound feed, and is a method for preparing sea cucumber compound feed by adding Enteromorpha. Background technique: [0002] Sea cucumbers belong to the Echinoderma ta (Echinoderma ta), Holothurioidea (Holothurioidea). The class of sea cucumbers is one of the most economically valuable classes in the phylum Acanthopanax. There are many species, and there are more than 1,100 species in the world. There are more than 100 species in my country’s seas, of which more than 20 are edible. In the 1980s, breakthroughs were made in sea cucumber artificial seed breeding technology, and seed breeding reached the level of large-scale. The scale of sea cucumber farming developed rapidly, and the scale of aquaculture continued to expand. The excessive growth of sea cucumber farming caused an urgent demand for compound feed, such as Sargassum and Sargassum. And the prices of large leaf algae have soared...

Problems solved by technology

In sea cucumber compound feed, the application of green algae such as kelp powder and sage algae powder is more common, but the application of Enteromorpha powder in sea cucumbers has not been reported.
