Family shellfish cultivation device

Abstract

The invention discloses a family shellfish cultivation device. According to the technical scheme, the family shellfish cultivation device is mainly characterized by comprising a body; the body is provided with a cultivation cavity with an opening facing upwards; the bottom part of the cultivation cavity is provided with a nozzle groove fitting the cultivation cavity; the interior of the nozzle groove is of a spherical structure; the center of the nozzle groove is fixedly provided with a first nozzle communicating with the nozzle groove; the first nozzle is of an L-shaped structure as a whole;one side of the body is further provided with a second nozzle communicating with the cultivation cavity; the inner diameter of the second nozzle and the inner diameter of the first nozzle are equal; an exit end of the second nozzle and an exit end of the first nozzle are arranged in parallel and face the same direction; the lower end of the body is further provided with a plurality of supporting structures connected with the body; and the upper end of the body is provided with a shading assembly fitting the cultivation cavity. The family shellfish cultivation device has the effects that the structure is simple, the seedling raising effect is good and the cultivation situation is convenient to observe.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a family shellfish cultivation and cultivation device. Background technique [0002] The whole process of shellfish farming mainly includes the selection of breeding sites, seedling raising, growing, fattening, harvesting and processing. Artificial breeding of shellfish seedlings includes stocking and selection of parent shellfish, artificial insemination, larva rearing, seedling picking and bait cultivation, etc. The cost of artificial breeding of shellfish is low, and by controlling the living conditions of the parents, the shellfish can be produced in advance, so as to make full use of the main growth period of the year, accelerate the growth of shellfish, shorten the production cycle, and can also be used for the breeding of high-quality shellfish. Variety available. [0003] The eggs of shellfish are mostly sinking eggs, which will disperse and sink to the bottom in st...

Problems solved by technology

[0005] In this patent, the first connecting pipe and the second connecting pipe are arranged on one side of the body, so that the water body can be replaced, but the seedlings on one side of the connecting pipe will be greatly affected by the replacement of the water body, while the other side will be less affected, and the cultivation cavity The bottom is easy to remain and cannot be drained, resulting in differences in the cultivation of shellfish seedlings, which in turn affects the effect of seedling cultivation

[0006] At the same time, in the process of shellfish cultivation and breeding, direct sunlight should be avoided, otherwise unnecessary death in the process of shellfish cultivation and breeding will be caused, and the cultivation effect of shellfish will be reduced. However, in the existing cultivation and breeding, the cultivation device is generally directly covered with sunshade Cloth or sun visor, but this will easily lead to the lack of air circulation in the breeding device, which will affect the effect of cultivation and breeding, and there is a problem of inconvenient retraction and retraction of the sun shade cloth or sun visor, which is not conducive to the cultivation personnel to observe the cultivation situation
