Embodiment Construction

[0015] The technical solution of the present invention will be further described through a typical embodiment below.

[0016] 1. Pond construction

[0017] 1. Pool type and pool depth: The pool type is designed to be rectangular, with an area of ​​20-50 mu. Its direction is determined according to the site's topographical characteristics and the direction of the monsoon, in order to facilitate the exchange of water bodies and mitigate the impact of wind and waves. The depth of the pool is 3.0m-3.5m, and the slope ratio is 1:1.5-1:2.5. The inlet and outlet gates are set separately, the bottom of the pool is inclined from the water inlet to the outlet, and the slope level is 20cm-45cm, so as to facilitate the drainage of the pond.

[0018] 2. Hardening of the bottom of the pool: First use the chain rail to mechanically roll it, and then use water after compaction. The method of watering is to enter water - soak - drain - expose to the sun, 2-3 times in a row, until the hardnes...

Abstract

The invention relates to an ecological trepang culture method in silt sandy ponds in coastlands, which belongs to the aquaculture field. The method comprises the steps of setting a pond, setting trepang reefs, disinfect the pond, controlling feed water, cultivating feedstuff, stocking young trepang and managing culture. The feedstuff culture which is performed in April to May comprises the following steps: firstly, transplanting benthic diatom in a height of 0.8 to 1 m feed water depth in the pond in the prior period, with 5 to 10 L of benthic diatom liquid per Chinese acre; secondly, transplanting ruppia maritime and amphilhoe japonice, especially, integrally transplanting ruppia maritime through pulling up by the roots according to the quantity of 5 to 15m per square meter, and transplanting amphilhoe japonica according to the quantity of 1.5 to 3 kg per Chinese acre after the transplanting of ruppia maritime; thirdly, poly-culturing mussel organism; fourthly, feeding water to the pond to the depth of 3 to 4 m, and stocking prawns according to the quantity of 500 to 1500 per Chinese acre. In the method of the invention, ecological feedstuff is adopted for transplanting and polyculture, therefore, not only the cost of artificial feedstuff is saved, but also the natural ecological environment is created for trepang culture.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to an ecological cultivation method for japonicus japonicus in muddy ponds along the coast. technical background [0002] As a kind of sea cucumber, sea cucumber has high edible and medicinal value, and is a traditional valuable seafood in my country. At present, the natural production is very small. Due to its ecological characteristics, its natural distribution and breeding area are narrow. In the past, breeding ponds were only built on the shore of rocky reefs or sandy shores with smooth currents. At the same time, due to the narrow breeding area, the density of breeding ponds was too high. , leading to more diseases in recent years, the yield, quality and benefit of sea cucumber farming have declined sharply, seriously affecting the development of sea cucumber farming. [0003] However, my country has a large number of muddy coasts and tidal flats. Due to the limitation o...
