Embodiment 1

[0016] (1) Pond conditions: Select a pond with a sediment bottom, with an area of ​​about 2 to 3 mu and a depth of 1 to 1.5 meters. River sand or sea sand with a thickness of 20-30 cm and a particle size of 0.5-3.0 mm is laid on the bottom of the pool.

[0017] (2) Treatment before transplantation: wash the cement pond with tap water and expose to the sun for 5-7 days. Sow commercially available sea cucumber ginseng feed according to the pool bottom area of ​​0.5 kg / m2, plow once on the sand surface to increase the mud content in the sand, and at the same time mix the fertilizer and sand evenly to increase the fertility of the sand , to provide sediment substrates and nutrients for the transplantation and growth of salt-loving grasses and the cultivation of rough sea cucumbers. The pond is divided into an area of ​​20 meters by netting 2 There are 2 grids, marked as 1# and 2#, to prevent rough sea cucumbers from drilling out.

[0018] (3) Investigation of salt-loving grass:...

Abstract

The invention discloses a method for ecological breeding of holothuria scabra in a halophila oralis transplanting sea grass bed. The method comprises the following technical steps of pond condtion setting, processing before transplanting, halophila oralis investigation, halophila oralis collection, halophila oralis transplanting, holothuria scabra breeding and pond water supplementing. The grass planting time and holothuria scabra specification are reasonably selected, the holothuria scabra is bred in the halophila oralis transplanting sea grass bed, and the ecological functions of the halophila oralis transplanting sea grass bed are successively utilized and embodied. No water change nor oxygen increase is needed in the breeding process, no drug is used, the cost is low, a breeding effect is good, and the method can serve as an efficient and ecological holothuria scabra breeding method. References are provided for sea grass resource recovery and holothuria scabra breeding in diversified modes. The weight of each holothuria scabra bred by adopting the method is up to 42.7-43.5 g, and the breeding time is 60 days.

Description

technical field [0001] The invention relates to an ecological breeding method for rough sea cucumbers in seagrass fields transplanted with salt-loving grasses, and belongs to the technical field of seawater farming. Background technique [0002] rough sea cucumber ( Holothuria scabra) , commonly known as "sha ginseng", has high nutritional value and medicinal value, and is one of the more popular edible sea cucumbers in southern my country. It has the characteristics of high temperature resistance and wide salinity. It mainly uses organic matter in sediments as nutrition, and mainly feeds on diatoms, bacteria, protozoa, cyanobacteria and foraminifera in the substrate, as well as organic debris of animals and plants. It is a typical sediment-feeding animal. At present, the natural resources of rough sea cucumbers distributed in Beihai, Guangxi are in a state of serious depletion. Domestic research on the cultivation of rough sea cucumbers is still in its infancy. There are ...
