Embodiment 1

[0016] (1) Pond conditions: select sedimentary ponds with an area of ​​about 2 to 3 mu and a depth of 1 to 1.5 meters. The bottom of the pool is laid with river sand or sea sand with a thickness of 20-30 cm and a particle size of 0.5-3.0 mm.

[0017] (2) Pre-transplant treatment: The cement pond is washed with tap water and exposed to the sun for 5-7 days. Sow commercially available sea cucumber feed at 0.5 kg / m2 of pool bottom area, plow the surface of the sand once 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 silt substrate and nutrients for the transplantation and growth of salt-loving grass and the cultivation of sea cucumber. The pond is divided into an area of ​​20 meters with a net 2 There are 2 grids marked as 1# and 2# to prevent sea cucumber from drilling out.

[0018] (3) Investigation of salt-loving grass: survey the distribution of salt-loving grass in the coastal w...

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 a method for ecological cultivating of sea cucumbers in a salt-loving grass transplanted seagrass field, and belongs to the technical field of mariculture. Background technique [0002] Rough sea cucumber (Holothuria scabra), commonly known as "Adenophora adenophorum", has high nutritional value and medicinal value, and is one of the most popular edible sea cucumbers in southern my country. It has the characteristics of high temperature resistance and wide salt. It mainly feeds on the organic matter in the sediments, and mainly feeds on the diatoms, bacteria, protozoa, cyanobacteria and foraminifers in the substrate, as well as the organic debris of animals and plants. It is a typical sedimentary animal. At present, the natural resources of sea cucumbers distributed in Beihai, Guangxi are in a state of severe exhaustion. Domestic research on sea cucumber cultivation is still in its infancy. There are relatively few reports on large...
