Full-life-stage recirculating aquaculture system of jellyfish and breeding method therefor

Abstract

The invention relates to a full-life-stage recirculating aquaculture system of jellyfish and a breeding method therefor. The full-life-stage recirculating aquaculture system of the jellyfish comprisesa dismountable breeding cylinder, a bottom cylinder, a filtering system, a water pump, an upper water pipe, a lower water pipe or the like. The upper water pipe is used for supply water to the breeding cylinder, and the lower water pipe is used for leading the water in the breeding cylinder out and into the filtering system in the bottom cylinder, so that the breeding water can be recycled between the breeding cylinder and the filtering system. The breeding cylinder provides power for motion and predation of the jellyfish and realizes an oxygenation effect by air holes and / or a porous water spraying pipe, and a porous inclined plate blocks the jellyfish so as to keep the jellyfish in the breeding cylinder, so that mechanical damage caused by jellyfish salvage can be avoided. The full-life-stage recirculating aquaculture system of the jellyfish, and the breeding method therefor solve breeding problems in different stages of a life cycle of the jellyfish, can also greatly save manpowerand time consumed in jellyfish breeding, increase breeding efficiency and are of good application prospect.

Description

technical field [0001] The invention relates to a jellyfish breeding technology, in particular to a jellyfish recirculating aquaculture system and a breeding method for all life stages. Background technique [0002] Most jellyfish have the phenomenon of alternation of generations, that is, the generation of polyp and the generation of jellyfish. Generations of polyps asexually proliferate through budding and podocyte formation. Under certain conditions, the hydra can transform into a transverse split body, and the transverse split body continues to develop and finally releases a disc-shaped body, which gradually grows into a medusa by feeding on plankton; after the disc-shaped body is released, the transverse split body can Revert to polyp again. [0003] The living habits and biological characteristics of different generations of jellyfish are completely different: individual polyps are tiny (2-10 mm) and live in the bottom habitat, and environmental conditions are needed...

Problems solved by technology

For example, the invention patent CN105794702B discloses a jellyfish disc culture device and its use method. Its structure includes a culture bottle and an electric roller bottle machine. In the specific experiment process, the disc is cultured in a plurality of cylindrical culture bottles Inside, the water flow power is provided by assembling it on an electric roller bottle machine. This device needs to be disassembled and opened to change the water and feed the culture bottle separately, which is time-consuming and labor-intensive.

For example, a jellyfish disc culture tank disclosed in the utility model patent CN207574308U provides water flow through pneumatic power. The dish-shaped body causes different degrees of loss. When feeding bait with a rolling cylinder that provides water flow, not only does the cylinder need to be disassembled for operation, but there is still the problem of changing the water that damages the disk-shaped body and consumes manpower.

For example, the utility model patent CN207531672U discloses a jellyfish disc culture device. In order to reduce the mechanical damage to the disc caused by the water change operation, two layers of gauze are added to separate the disc culture space and used for In the storage chamber for water change, fresh water is added to the breeding tank, and then excess sewage is introduced into the sewage storage bottle through the storage chamber through the height difference. The gauze net is very easy to catch residual bait and breed bacteria and algae. Screws and other objects in disassembly are easy to rust in seawater and damage the ornamental value of the cylinder, and changing the water is labor-intensive

The utility model patent CN207531700U discloses a dish-shaped body jellyfish breeding water circulation system. Water storage tanks are added on the left and right sides of the culture tank. The two sides of the dish-shaped body culture tank are provided with sieve plates that communicate with the water storage tank to allow water to pass through the dish-shaped body. Keep it in the breeding tank to reduce the damage to the dish caused by the water flow of the water circulation system. The structure of the breeding system is complex, the space utilization rate is low, and the water flow is only provided by pneumatic, and the application scene is single

Invention patent application CN107455317A discloses an automatic water exchange system for jellyfish breeding and its application. In order to solve the problem of water exchange for jellyfish discs and larvae, an electric rotating device is used, but the design of the entire device is complicated, and the entire electronic rotating device needs to be placed in the The upper part of the breeding tank does not provide the space required for its movement track. Not only the space utilization rate is low, but also the difficulty in the attachment of residual bait and the replacement of sieve silk also brings problems to the actual breeding operation.
