Description

System for be used for gobiocypris rarus spawning and spawning collection ovum

Technical Field

The invention relates to a fish egg collecting tool, in particular to a system for spawning and egg collecting of gobiocypris rarus.

Background

The gobiocypris rarus adult has the total length of 38-85mm, is convenient to feed, and as early as 1990, the institute of aquatic organisms of the academy of sciences of China aims to use the gobiocypris rarus as a new experimental animal, and systematic research is carried out on the distribution area, the aspects of life habit, form and classification status, reproduction, embryonic development, post-embryonic development, growth, feeding, adaptability to ecological factors, karyotype and isozyme, feeding methods, reproduction technology, anesthesia methods, inbreeding line cultivation and the like.

Gobiocypris rarus belongs to the type of continuous spawning, and the same gobiocypris rarus spawns once every 4 days, hundreds of spawns are generated every time, and a large number of offspring of the same parent can be obtained in a short period. However, gobiocypris rarus is mainly carried out on the surface of a water body in the spawning process, fish eggs sinking to the water bottom are easily swallowed by breeding fish on one hand, and are easily mixed with feed and excrement in a fish tank on the other hand, experimenters need to obtain the fish eggs and are screened in a large amount, so that the workload is very large, and the efficiency is extremely low. Meanwhile, gobiocypris rarus who finish spawning can influence the staff to collect fish eggs. In addition, if a large amount of gobiocypris rarus cannot supplement dissolved oxygen to water in time in the spawning process, the gobiocypris rarus cannot survive easily.

Disclosure of Invention

The invention provides a gobiocypris rarus spawning and spawning system which has the advantages of convenience in spawning collection and purity in spawn obtaining.

In order to achieve the purpose, the invention provides the following technical scheme:

the utility model provides a system that is used for gobiocypris rarus to spawn and collect ovum, includes and is used for holding gobiocypris rarus and one end open-ended column container, still includes: the egg collecting device is used for collecting fish eggs; the oxygenation device is used for increasing dissolved oxygen in water so that gobiocypris rarus can survive more easily; the transplanting device is used for transferring gobiocypris rarus after spawning is finished to the fish tank; the egg collecting device, the oxygen increasing device and the transplanting device are all positioned in the hollow part of the columnar container; the egg collecting device comprises a columnar egg laying chamber with openings at two ends and a collecting net for collecting fish eggs, the collecting net is detachably arranged below the columnar egg laying chamber, and an isolating net cover for preventing gobiocypris rarus from swallowing the fish eggs is arranged between the two opening end faces of the columnar egg laying chamber; oxygenation device is including increasing hydraulic pump body and being used for avoiding rare gobiocypris cruris to swim into the pump body and the safety cover that harms, and the safety cover is equipped with the through-hole that is used for leading to the drainage, the pump body is located inside hollow safety cover.

Wherein, gobiocypris rarus spawns in the room of column spawning, and the roe is collected in falling to collecting the net by isolation screen panel department, and wherein roe and fodder etc. homoenergetic are through isolation screen panel, and collect the net mesh and can only supply the roe to pass through, therefore fodder and fish excrement and urine etc. can subside to column container bottom, collect in the net promptly for pure roe, have made things convenient for the collection of staff to the roe. The aperture of the isolation net cover is 2-4 mm, fish eggs and fish feed can pass through the isolation net cover, the meshes of the collection net cover are 0.5-1.0 mm, the fish feed can conveniently pass through the isolation net cover, and the fish eggs cannot pass through the isolation net cover.

And the pump body is located inside the protective cover, water in the cylindrical container can be extracted, and simultaneously the water is discharged through the through holes in the protective cover, so that the contact area between the water in the cylindrical container and air is increased, the dissolved oxygen in the cylindrical container is increased, and the gobiocypris rarus survival is facilitated.

Preferably, the isolation net cover is located at the joint of the collection net and the columnar spawning chamber, and the isolation net cover is detachably provided with artificial duckweed simulating natural aquatic weeds to promote the gobiocypris rarus to spawn. The artificial duckweed is made by the gauze material, can simulate pasture and water among the ecological environment, is favorable to the ovulation of gobiocypris rarus more, simultaneously, because the roe has high viscidity, consequently when the gobiocypris rarus finishes laying eggs, only need with artificial duckweed go up the roe of adhesion wash down can, the collection ovum process is more convenient. The artificial duckweed is in lock joint fit with the isolation net cover through the mortise lock, so that the egg taking by workers is more convenient.

Preferably, a slow flow cover for enabling water flow to be stable is arranged on the outer side of the oxygen increasing device, the slow flow cover is columnar, and a water through hole for water flow to pass through is formed in the side wall of the columnar slow flow cover. The setting of unhurried current cover can prevent that the rivers in the cylindrical container from too torrentially and making the roe fall into the spawning of the external and influence rare gobiocypris crucian of album ovum device.

Preferably, the invention further comprises a plurality of connecting rods for fixedly connecting the egg collecting devices and the slow flow cover, correspondingly, the number of the egg collecting devices is multiple, and the egg collecting devices are circumferentially fixed on the side wall of the slow flow cover through the connecting rods.
