Embodiment Construction

[0022] The method for breeding new sea cucumber seedlings of the present invention includes the following steps:

[0023] (1) Pro-participation management:

[0024] Cement tanks are used in the storage tanks, and single-layer floating cages are used for temporary cultivation, with a cultivation density of 15-25 heads / m 3 , Water depth 1.2~1.5 meters, water temperature 16~18℃, salinity 29~32‰, PH value 7.8~8.5, light 500~1000lx, dissolved oxygen above 5㎎ / l; relative ginseng is calculated at 4% of its body weight per day % Feed the Sargassum grind liquid twice in the morning and evening; change the water once a day in the morning and evening, the amount of water change each time is 1 / 3 to 1 / 2, and the temperature difference of the water is not more than 1℃;

[0025] (2) Egg laying and fertilization:

[0026] The spawning density is not more than 50 grains / m2, the parent ginseng should be removed in time after fertilization, and the eggs should be washed repeatedly with clean sea wa...

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 involves a method of breeding of animal seedlings. Specifically, it involves a new type of spiny seedlings breeding method, which belongs to the field of animal breeding technology. Background technique [0002] The development of thorns breeding industry is an important way to develop and use marine biological resources. In recent years, it has developed rapidly in recent years. The breeding area has expanded rapidly and has significant economic and social benefits. It has become one of the important industries in my country's sea and water breeding.Many breeding manufacturers are engaged in artificial breeding of thorns. However, existing breeding methods: First, the breeding yield is unstable and the output is low; second, the seedling body is weak; the third is that the seedlings are different.As a result, the further improvement and industrialization of thorns breeding levels are restricted. Invention content [0003] The purpose of the ...
