Embodiment 1

[0021] a. Establish sea cucumber culture ponds: choose seawater with smooth tide, fresh water quality (salinity 28-36, pH7.8-8.4, dissolved oxygen 4-11mg / L, COD10-15mg / L), no pollution, no large rivers (Fresh water) inflow areas to build ponds, and the area of ​​the ponds is 5hm 2 (5 hectares) is appropriate, the depth of the pool should be guaranteed to be at least 1.5m, the bottom of the pool is mud or sand bottom and two high and low inlet and drainage gates are set;

[0022] b. Carry out clearing treatment to the japonicus breeding pond and discharge the water; after cleaning the pond, enter 30-40cm of water, and sprinkle bleaching powder (150-300kg / hm) on the whole pond 2 ) or quicklime (900~1200kg / hm 2 ) Clean pond, remove wild fish and crabs in the pond, etc., eradicate large plants such as Clado algae in the pond, and drain the water after 2 days in the pond;

[0023] c. Place reef cages with a spacing of 2-3m and a density of 1200 per hectare, then bring in natural ...

Embodiment 2

[0028] a~b step is the same as embodiment 1;

[0029] c. Place reef cages with a spacing of 3m and a density of 1200 per hectare, and then bring in 0.45m deep natural seawater and carry out water cultivation, so that the biomass of phytoplankton in seawater is 10-20mg / L, and zooplankton 2 , benthic organisms 2 ;

[0030] d. Put the ginseng seedlings into the reef cages, put in 100 sea cucumbers / kg, and throw 50 sea cucumbers in each reef cage, then seal the reef cages with nets, and then enter the natural sea water with a water depth of 1.5m;

[0031] e. After 12 months of breeding, sea cucumbers reach commercial specifications, with an average weight of 120g / head, and a survival rate of 92%. During the breeding period, the water should be changed once a day, and the amount of water changed should be more than 20%. The water change amount can be adjusted in time according to the water temperature and water quality of the pond. , Generally, the water exchange volume in spring a...

Abstract

The invention discloses an Apostichopus japonicus Selenka pond reef cage culture method capable of improving the Apostichopus japonicus Selenka survival rate and recapture rate, reducing the culture cost, facilitating Apostichopus japonicus Selenka commodity harvest, and benefiting the timely pond cleaning treatment. The method comprises the following steps: establishing an Apostichopus japonicus Selenka culture pond; cleaning the Apostichopus japonicus Selenka culture pond and discharging the water; placing reef cages according to the pitch of 2 to 3m and the density of 1,200pcs / hectare, admitting 0.45 to 0.55m natural seawater and culturing the water so as to have 10 to 20mg / L of phytoplankton biomass, less than 10mg / L of zooplankton, 50 to 60g / m of attaching organism, and less than 70mg / m benthos in the seawater; placing the Apostichopus japonicus Selenka seedlings in the reef cages with the dosage specification of 50pcs of Apostichopus japonicus Selenka for each reef cage, 100 to 500pcs of Apostichopus japonicus Selenka being equal to 1kg, then closing the reef cages with webs, and then admitting natural seawater to the depth of at least 1.5m; culturing the Apostichopus japonicus Selenka to reach the commodity specifications; and during harvesting the Apostichopus japonicus Selenka, taking out the reef cages, taking out the anchoring beds, catching the bigger Apostichopus japonicus Selenka and leaving the smaller Apostichopus japonicus Selenka, and catching and stocking the Apostichopus japonicus Selenka in rotation.

Description

Technical field: [0001] The invention relates to a method for cultivating sea cucumbers, in particular to a method for cultivating sea cucumbers in ponds and reef cages, which improves the survival rate and return rate of sea cucumbers, reduces the cost of cultivation, facilitates harvesting of commercial ginseng, and facilitates timely pond cleaning. Background technique: [0002] Sea cucumber (Apostichopus japonicus Selenka), also known as sea cucumber, belongs to Echinodermata phylum Echinodermata, Holothuroidea class, Aspidochrotida order Apostichopus, and sea cucumber genus Apostichopus. Sea cucumber is rich in nutrients, high in protein content and does not contain cholesterol. The chondroitin sulfate contained in it has the effect of strengthening the body, resisting aging and inhibiting tumors. Therefore sea cucumber is a high-grade tonic and the crown of sea treasures. At present, the main method of sea cucumber pond culture is reef culture, which is to throw rocks...
