Problems solved by technology

The existing oyster family larva cultivation facilities are simple, often only have independent plastic buckets, the cultivation process needs to change water regularly, and the water-changing mesh bags are recycled between families, which is easy to cause the larvae of different families to mix
In addition, the weight of the plastic bucket containing the larvae is heavy, which makes the water change process cumbersome, time-consuming and laborious, and lacks a special and effective family larvae cultivation device

Embodiment 1

[0027] Such as Figure 1-3 As shown, a device for cultivating oyster family larvae includes a bait bucket 1, a water storage bucket 2, a larvae cultivation tube 3, a cultivation tube support 4 and a piping system; it is characterized in that: the piping system includes an oxygen pipe 5, a water inlet pipe 6. The bait pipe 10 and the main drainage pipe 14; the front end of the oxygen pipe 5 is connected with an air pump 7, and the middle part is connected with a branch, which is respectively passed into the bait bucket 1 and the water storage bucket 2, and the end is passed into the larvae cultivation pipe 3; one end of the water inlet pipe 6 passes into the water storage bucket 2, and the other end passes into the larvae cultivation pipe 3; the two ends of the bait pipe 10 pass into the bait bucket 1 and the water storage bucket 2 respectively; The bait bucket 1 and the water storage bucket 2 are respectively provided with a water pump I8 and a water pump II9; the water inlet ...

Embodiment 2

[0037] The difference between this embodiment and Embodiment 1 is that: filter cotton, activated carbon, volcanic rock and biological filler are respectively filled in the water purifying device from top to bottom. The aquaculture water flowing into the water storage tank 2 from the drainage main pipe 14 passes through multi-layer filter materials to ensure that the filter effect is good, so that it can be recycled; the biological filler can provide a living attachment environment for bacteria such as nitrifying bacteria to decompose organic Impurities.

[0038] The usage method of this embodiment is the same as that of Embodiment 1.

Embodiment 3

[0040] The difference between this embodiment and Embodiment 2 is that: each group of branch drainage pipes 13 is provided with a screen at the nozzle position. The sieve can block bait and some oyster larvae and avoid entering the main drain 14 .

[0041] The usage method of this embodiment is the same as that of Embodiment 1.

Abstract

The invention discloses an oyster family larva breeding device and a using method thereof. The oyster family larva breeding device comprises a bait barrel, a water storage barrel, a larva breeding pipe, a breeding pipe support and a pipeline system, wherein the pipeline system comprises an oxygen pipe, a water inlet pipe, a bait pipe and a main drainage pipe; the oxygen pipe is connected with an air pump, and branches are led into the bait barrel, the water storage barrel and the larva breeding pipe; the two ends of the water inlet pipe are led into the water storage barrel and the larva breeding pipe respectively; the two ends of the bait pipe communicate with the bait barrel and the water storage barrel respectively; a water pump I and a water pump II are arranged in the bait barrel andthe water storage barrel respectively; the water inlet pipe and the bait pipe are connected with the water pump II and the water pump I respectively; the larva breeding pipe is erected on the breedingpipe support, the upper portion of the larva breeding pipe is connected with a branch drainage pipe, and a screen pipe is arranged in the larva breeding pipe; the branch drainage pipe is connected with the main drainage pipe; and the main drainage pipe is led into the water storage barrel. The oyster family larva breeding device is simple and practical, oyster larvae can be prevented from beingmixed, water changing and bait casting are facilitated, workloads are reduced, and the breeding efficiency and the quality are improved.

Description

technical field [0001] The invention belongs to the technical field of oyster cultivation, and relates to a device for cultivating oyster family larvae and a method for using the same. Background technique [0002] Family selection is an effective method for cultivating new varieties and has been widely used in animal or plant breeding. Family establishment and systematic selection are important means of genetic breeding. There have been many successful cases of oyster trait improvement using family selection, and successful breeding of Chang Muli Haid No. 1, Chang Mu Li Haid No. 2 and Fujian Muli No. 1 and other excellent new varieties. [0003] Family selection Since the whole family is used as the unit for selection or elimination, each family should be isolated from each other or clearly marked, and not mixed with each other. The existing oyster family larva cultivation facilities are simple, often only have independent plastic buckets, the cultivation process needs to...
