Problems solved by technology

Many breeding factories are engaged in the artificial breeding of sea cucumbers, but the existing breeding methods: first, the breeding yield is unstable and low; second, the seedlings are weak; third, the seedling specifications vary greatly
Therefore, the further improvement and industrialization of sea cucumber breeding level are restricted.

Embodiment Construction

[0022] The breeding method of novel sea cucumber seed of the present invention, comprises the steps:

[0023] (1) Ginseng storage management:

[0024] The storage pond adopts cement tanks, adopts single-layer floating net cages for temporary cultivation, and the cultivation density is 15-25 heads / m 3 , the water depth is 1.2-1.5 meters, the water temperature is 16-18°C, the salinity is 29-32‰, the pH value is 7.8-8.5, the light is 500-1000lx, and the dissolved oxygen is above 5㎎ / l; % Feed the sargassum grinding solution twice in the morning and evening; change the water once a day in the morning and evening, each time the water change is 1 / 3 to 1 / 2, and the temperature difference between the water changes is not greater than 1°C;

[0025] (2) Oviposition and fertilization:

[0026] The egg-laying density is not more than 50 grains / ㎡, and the parent-ginseng is removed in time after egg-laying and fertilization, and the eggs are repeatedly washed with clean seawater sterilized...

Abstract

The invention provides a novel stichopus japonicus fry breeding method which includes: controlling seeding density to 0.5-1 / ml, changing water everyday, controlling water temperature at 20-25 DEG C, and cleaning bottom every 2-3 days; moving the fries into a breeding pool; using a transparent polyethylene corrugated board as a substratum, and keeping water temperature at 15-23 DEG C, illumination at 500-1000lx, salinity at 29-32%, dissolved oxygen above 5mg / l, pH at 7.8-8.5, and breeding density at 0.5-1 / cm<2>; keeping water in the breeding pool to flow so as to improve water quality; feeding feed mainly made of sargassum thunbergii powder, sargasso powder, fish meal, yeast, sea mud, immune polysaccharides and / or steel wire algae; feeding photosynthetic bacteria to purify water quality; cleaning dirt. By the method, quality and yield of stichopus japonicus breeding are increased.

Description

technical field [0001] The invention relates to a method for raising animal seedlings, in particular to a method for breeding novel sea cucumber seedlings, and belongs to the technical field of animal breeding. Background technique [0002] The development of japonicus aquaculture is an important way to develop and utilize marine biological resources. It has developed rapidly in recent years, the aquaculture area has expanded rapidly, and the economic and social benefits have been remarkable. It has become one of the important industries of marine aquaculture in my country. Many breeding factories are engaged in the artificial breeding of sea cucumbers, but the existing breeding methods: the one, the breeding yield is unstable and low; the second, the seedlings are weak; Therefore restricting the further improvement and industrialization of sea cucumber breeding level. Contents of the invention [0003] The purpose of the invention is to overcome the deficiencies of the p...
