Problems solved by technology

[0004] Since sea cucumber culture in net cages is a culture method developed in recent years, there is no special compound feed suitable for this culture technology. The existing sea cucumber feed is generally divided into juvenile ginseng feed, juvenile ginseng feed, etc. according to the age or body length of sea cucumbers. feed and growing feed, and most of these feeds are powdered feeds, which are not suitable for use in cage culture cond

Abstract

The invention relates to manual compound feed for a sea cucumber when the sea cucumber or an apostichopus japonica is cultured in a net cage. The feed comprises components of raw materials in parts by mass as follows: 5-10 parts of sargassum thunbergii, 20-30 parts of sargassum, 5-10 parts of white fish meal, 10-20 parts of scallop skirt powder, 5-10 parts of shrimp shell meal, 5-10 parts of fermented bean meal, 20-25 parts of kelp meal, 1-2 parts of refined fish oil, 0.2-0.5 part of compound vitamin and 0.2-0.5 part of a compound trace element. The raw materials are weighed proportionally and mixed to be uniform, coarse powder is ground, the materials obtained by grinding the coarse powder are subjected to superfine grinding to 80 meshes and then bonded and extruded to form platy feed, and the feed is packed after dried. The feed can meet requirements of ingestion and nutrient of the sea cucumber under the culture condition of the net cage, and can increase the growing speed of the sea cucumber cultured in the net cage; compared with an ordinary feeding manner, the weight gain rate is improved by 78.8%; and the feed waste can be reduced, the utilization rate of the feed is improved, and the pollution of residual bait to cultivation sea water is reduced.

Description

technical field [0001] The invention relates to a sea cucumber feed, in particular to a formula and a production method of an artificial compound feed for sea cucumbers used when culturing sea cucumbers (imitation sea cucumbers) in net cages. Background technique [0002] Sea cucumbers belong to the phylum Echinodermata, the class Holothuria, the order Apostichopus, the family Apostichopaceae, and the genus Apostichopus. It has a history of more than 600 million years. Sea cucumbers feed on seabed algae and plankton. Modern studies have shown that sea cucumbers can improve memory, delay gonadal aging, prevent arteriosclerosis, diabetes, and anti-tumor effects. They have important edible and medicinal values, and are important aquaculture species in my country. There are more than 20 kinds of edible sea cucumbers produced in my country's sea areas, among which artificially cultivated sea cucumbers are mainly imitation sea cucumbers, mainly produced in Dalian, Lushun and Haiya...
