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 a suitable place, spread them evenly in the pool at a seedling density of 80 heads / m3 of water body, and feed the...

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 non-polluted 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 stoc...

Abstract

The invention belongs to the technical field of mariculture and particularly discloses an ecological mixed culture method employing a concrete pond for stichopus variegatus seedlings and sipunculid. By adopting the technical measures of culture pretreatment, seedling placement and feeding and culture environment control, and through reasonably arranging the seedling placement specification and time, ecologically mutually beneficial and complementary mixed culture of the stichopus variegatus seedlings and the sipunculid is successfully achieved by combining stichopus variegatus seedling cultivation with a sipunculid breeding technology. Through a change of a culture mode, the nutrient diffusion flux of a sediment-water interface is increased to improve a substrate by using a ''burrowing'' process of the sipunculid and ''biological washing''; the incidence rate in stichopus variegatus seedling cultivation is effectively reduced; the space utilization rate of the culture cement pond is effectively improved; water is purified; the culture environment is improved; and obvious yield-increase and value-addition effects are achieved.

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...
