Embodiment approach 1

[0015] Embodiment 1, refer to appendix figure 1 , 2 . Bend with 5mm diameter thin steel bar figure 1 The skeleton shown is sprayed with a layer of plastic afterwards, wherein the apex angle of the first isosceles triangle 1 is 40°, and the height is 90cm; The length is 110 cm; the height of the first column 7 and the second column 8 is 70cm, and the mesh number is that the polyethylene mesh of 15 objects is wrapped in the top beam 3, the left bottom beam 4, the right bottom beam 5 and is formed in two pairs It also covers the two planes formed by the middle beam 6 and the left bottom beam 4 and the middle beam 6 and the right bottom beam 5 on the three planes.

Embodiment approach 2

[0016] Embodiment 2, refer to image 3 . The depth of seawater in culture pond 3 is 1.7m, and the pond area is 10,000 square meters; when short octopus larvae are placed in the culture pond, the predators of short octopus larvae such as large fish and crabs in the pond are removed; The density of 2.0m spacing is evenly placed at the bottom of the pond, and then the hatched octopus larvae are put into the outdoor sea cucumber pond at a density of 10-20 per shelter after 2 days of indoor nutrition enhancement.

Abstract

The invention discloses a shelter and a method for mixed cultivation of short octopus and sea cucumber. The shelter mainly consists of a skeleton with a polyethylene mesh attached to it and is foldable for storage. The mixed culture method mainly includes the production of shelters and their layout in the sea cucumber culture pond, the removal of harmful organisms in the pond, the appropriate timing and appropriate density of octopus larvae. The present invention utilizes the characteristics that octopus and sea cucumber do not ingest each other and do not interfere with each other, and the sea cucumber reef can be used as a shelter for octopus larvae and adult stages; at the same time, according to the food chain relationship in the pond, the sea cucumber breeding pond is rich in clawed feet and small The advantages of shrimp and crabs as bait for different stages of octopus make octopus grow fast and have a high survival rate, which improves the economic benefits per unit area of ​​sea cucumber culture ponds.

Description

technical field [0001] The invention belongs to the technical field of marine culture, in particular to a mixed culture method of octopus and sea cucumber. Background technique [0002] At present, sea cucumber aquaculture is in full swing, and the technology of polyculture of fish, shrimp, crab, abalone and sea urchin has appeared, but there are few reports of polyculture of sea cucumber. [0003] Short octopus ( Octopus ocellatus Gray, 1849) belongs to the mollusk Cephalopoda, Octopoda, Octopodidae, and Octopus, and is one of the most important economic species in the northern coastal octopus in my country. [0004] As a new breed of northern octopus, its artificial seedling, indoor pond and outdoor earth pond culture technologies are mature and put into production and application. However, due to some inherent biological characteristics of the short octopus, the production per unit area of ​​the short octopus is not high, and the output value per unit area is low. Unde...
