Feed special for trepang cage culture

Abstract

The invention provides feed special for trepang cage culture, and belongs to the technical field of trepang culture. The feed is prepared from basic feed and feed additives special for trepang cage culture, wherein the weight ratio of the basic feed to the feed additives is 100:(2-6). The basic feed is prepared from, by weight, fermented corn flour, degumming kelp powder, gulfweed powder, krill powder, hydrolyzed fish protein, fish oil, nucleotide and / or nucleoside, digestible amino acids, vitamin premix compounds and 0.8-1 part of mineral substance premix compounds. The feed has the advantages that abundant nutrients are supplied for metabolism of fatty acid and amino acids inside trepang bodies; the feed has the high food calling effect, the food intake is increased, the feed utilizationrate is remarkably lowered, and the feed conversion ratio is lowered; the special feed has the good effect on preventing trepang adverse stress reactions and improving the tolerance for adverse environment factors.

Description

technical field [0001] The invention belongs to the technical field of sea cucumber cultivation, and in particular relates to special feed for sea cucumber cultivation in cages.

Problems solved by technology

[0003] Sea cucumbers are very important health supplements in many cases. When sea cucumbers are used, sea cucumbers are always wild, which is the so-called wild sea cucumbers. Generally speaking, wild sea cucumbers grow in a completely wild state. Therefore, its growth period will be relatively long, and its output will be greatly limited. Therefore, people have to propose the artificial cultivation of sea cucumbers. Among them, sea cucumber cage cultivation technology is a relatively good cultivation method. Sea cucumbers are cultivated by dividing areas, so that sea cucumbers can be grown in the ocean, but sea cucumber cage culture needs to select suitable seedlings, so in the process of sea cucumber cage culture, special compound feed suitable for this breeding technology Very important, the existing sea cucumber feed is generally divided into juvenile ginseng feed, juvenile ginseng feed and grow-out feed according to the age or body length of sea cucumbers, and most of these feeds are powder feeds, which are not suitable for use in cage culture conditions.
