Larva stichopus japonicas feed and production method thereof

Abstract

The invention discloses larva stichopus japonicas feed for preventing larva stichopus japonicas from excrement dragging in a high water temperature period, promoting growth of the larva stichopus japonicas and increasing the survival rate of the larva stichopus japonicas, and a production method thereof. The larva stichopus japonicas feed consists of the following components in pars by mass: 20-25 parts of sargassum, 20-25 parts of sargassum thunbergii, 15-20 parts of shell powder, 5-10 parts of melt roots, 10-15 parts of sargassum fusiforme, 5-10 parts of zostera marina, 3-10 parts of soybean meal, 3-10 parts of ulva lactuca, 0.5-1 part of scallop skirt powder, 1-3 parts of spirulina and 1-3 parts of yeast. The production method comprises the following steps: spreading and drying the raw materials, namely, the sargassum, the sargassum thunbergii, the sargassum fusiforme, the zostera marina, the soybean pulp and the ulva lactuca in air; removing impurities and sand; crushing till the granularity is 200 meshes; stirring and mixing.

Description

technical field [0001] The invention relates to a feed and a production method thereof, in particular to a juvenile ginseng feed and a production method thereof which can prevent juvenile ginseng from defecation, promote the growth of juvenile ginseng and improve the survival rate of juvenile ginseng. Background technique [0002] sea ​​cucumber ( Stichopus japonicus ) is usually called sea cucumber, which belongs to Echinodermata, Holothuroidea, Aspidochirota, Stichopodidae in classification, and is mainly distributed in Japan, China, Korea and the Russian Far East , mainly distributed in Liaoning, Shandong, Hebei and other northern coastal areas in China. Sea cucumber has high nutritional health and medical value, is an important treasure of marine economic resources, and has become one of the main cultured species in the aquaculture industry. [0003] Juvenile ginseng usually refers to sea cucumbers whose body length (natural extension) is ≤1cm after the larvae attach. ...

AI Technical Summary

Problems solved by technology

The existing young ginseng feed is generally prepared in proportion from sargassum, sargassum, shell powder, hijiki, degummed kelp, shrimp bran, subpowder, soybean meal, Ulva, scallop skirt powder and yeast. When the high temperature rises, young ginseng often has defecation (the length of feces is 10~20mm), poor appetite, etc., and a few have vomiting, which seriously affects the growth and survival rate of young ginseng

At the same time, poor appetite will lead to excess residual bait in the aquaculture water, pollute the aquaculture water, aggravate sea cucumber diseases, and blindly use antibiotics, which will inevitably lead to problems such as bacterial resistance and drug residues
