Embodiment 1

[0022] 1) Pre-cultivation treatment: select 4 square cement ponds, 2 polyculture ponds, and 2 control ponds, with an area of ​​10m 2 , 1.2m deep, the aquaculture cement pool is disinfected with a commercially available disinfectant of potassium permanganate mixed with water, the dosage is 5ppm, the wall and bottom of the cement pool are washed with the disinfectant, and after disinfection, it is thoroughly rinsed with a high-pressure water gun, and then After drying for 5 days, arrange the trachea and inlet and outlet pipes in the pond. After preparing the breeding pond, place 160 corrugated board frames, a total of 2 layers, leaving 30cm gaps around the pond. , After sedimentation, pour into the culture pond, store 100cm of water and wait for the seedlings to be released;

[0023] 2) Seed placement and feeding: the healthy sea cucumber seedlings of 1-3cm are stocked in a mixed culture pond, and evenly spread to the pool at a density of 100 heads / m3 of water body, every evenin...

Embodiment 2

[0027] 1) Pre-cultivation treatment: select 2 square cement ponds with an area of ​​15m 2 , 1.3m deep, the aquaculture cement pool is disinfected with commercially available potassium permanganate mixed with water, the dosage is 5ppm, the wall and bottom of the cement pool are washed with disinfectant, and after disinfection, it is thoroughly rinsed with a high-pressure water gun, and then After drying for 5 days, arrange the trachea and inlet and outlet pipes in the pond. After preparing the breeding pond, place 220 corrugated board frames, a total of 2 layers, leaving 30cm gaps around the pond; the breeding water is non-polluting seawater in the sea area, filtered , After sedimentation, pour into the culture pond, store 100cm of water and wait for the seedlings to be released;

[0028] 2) Seed placement and feeding: put healthy sea cucumber seedlings of 3-5 cm in stock, spread them evenly in the pool at a seedling density of 80 heads / m3 of water body, and feed them once ever...

Embodiment 3

[0032] 1) Pre-cultivation treatment: select 4 square cement ponds, 2 polyculture ponds, and 2 control ponds, with an area of ​​10m 2 , 1.2m deep, the aquaculture cement pool is disinfected with a commercially available disinfectant of potassium permanganate mixed with water, the dosage is 5ppm, the wall and bottom of the cement pool are washed with the disinfectant, and after disinfection, it is thoroughly rinsed with a high-pressure water gun, and then After drying for 5 days, arrange air pipes, inlet and outlet pipes in the pond, lay sea sand with a thickness of 20cm and a particle size of 1-2.0mm as the bottom sand of the pond. A 30cm gap is left around the pond; the water for cultivation is unpolluted seawater in the sea area, after sand filtration and sedimentation, it is poured into the cultivation pond, and the water is stored at 100cm to wait for the seedlings to be released;

[0033] 2) Seed placement and feeding: the healthy sea cucumber seedlings of 1-3cm are stocke...

Abstract

The invention belongs to the technical field of seawater culture, and specifically relates to an ecological polyculture method for cement ponds of japonicus japonicus seedlings and star worms. Adopting the technical measures of pre-breeding treatment, seed placement and feeding, and breeding environment regulation, through reasonable arrangement of seedling specifications and time, combined with the cultivation of sea cucumber seedlings and starworm breeding technologies, the ecological mutual benefit and complementarity of the two has been successfully realized. Mixed breeding. In the present invention, by changing the breeding mode, using the process of "cave building" and "biological washing" to increase the nutrient salt diffusion flux at the sediment-water interface to improve the bottom quality, effectively reduce the incidence of Apostichopus japonicus seedling cultivation, and effectively Improve the space utilization rate of the breeding cement pool, purify the water quality, improve the breeding environment, and achieve obvious effects of increasing production and value.

Description

【Technical field】 [0001] The invention belongs to the technical field of seawater culture, and in particular relates to an ecological polyculture method for cement ponds of japonicus japonicus seedlings and star worms. 【Background technique】 [0002] Sipuncula is a general term for all worm-like marine invertebrates. There are about 320 known species, which are divided into 4 families: 1. Sipunculidae; 2. Golfingiidae; 3. Aspidosiphonidae 4. Phascolosomatidae. [0003] Phascolosoma esculenta, commonly known as Haiding, sandworm, etc., is a unique species of star worm in China. It is distributed in the southeast coast, and the resources along the Beibu Gulf are particularly rich. It lives in caves in the intertidal zone and lives as a benthic diatom , organic debris for food. The delicious meat and rich nutrition of the delicacy starworm has the effects of nourishing yin and reducing fire, tonifying the kidney and improving intelligence. It is known as the "Cordyceps sinens...
