Laboratory aquaculture device for breeding aquatic products with circulating water

Abstract

The invention discloses a laboratory aquaculture device for breeding aquatic products with circulating water. The device includes a circular circulating water pool, a separation-pool intake channel, an arc-shaped sieve buffering water distribution pool, a first-stage biological filter bubble collection and discharge pipe, a second-stage biological filter and a water storage pool. The bottom of thecircular circulating water pool is fixedly provided with a solid-liquid separation drainage pipe, the separation-pool intake channel is formed in an eddy-current type separation pool, the arc-shapedsieve buffering water distribution pool is located on the side of the eddy-current type separation pool, the first-stage biological filter bubble collection and discharge pipe is arranged on the sideof a first-stage biological filter, the second-stage biological filter is located on the other side of the first-stage biological filter, and the water storage pool is located above a pipeline drainage ditch. According to the laboratory aquaculture device for breeding the aquatic products with circulating water, recycling of a water source can be achieved for large-scale aquatic-product breeding,meanwhile the water processing efficiency is improved, the creature holding capacity of the system is improved, circular purification work of the water source is facilitated, and the consumption of auxiliary labor is reduced.

Description

technical field [0001] The invention relates to the technical field of aquatic product laboratory cultivation, in particular to a laboratory cultivation device for aquatic product circulating water cultivation. Background technique [0002] In order to facilitate the water circulation culture of aquatic products in the laboratory, it is convenient for the experimenter to observe the growth status of aquatic products and the influence of the use of circulating water on the biological activity of aquatic products, it is necessary to set up an independent aquatic product breeding area and water circulation in the experiment The equipment is used to facilitate the observation of experimental data, reduce the error of experimental data caused by external environmental factors, and set up an independent water ecological environment circle, so that the experimenters can easily change the environmental temperature of the ecological environment circle and the types of aquatic products...

Problems solved by technology

[0007] The object of the present invention is to provide a kind of aquatic product circulating water cultivation laboratory breeding device, to solve the above-mentioned background technology, propose the existing aquatic product circulating water cultivation laboratory breeding device, the use form of the equipment is small, and it is inconvenient to carry out large-scale cultivation during utilization. It is difficult to collect comparative experimental data for aquatic product farming. Local small aquatic product farming is prone to individual errors in the collection of aquatic product farming data due to individual factors. The removal efficiency is not high. In long-term use, the quality of self-used recycled water is difficult to meet the requirements of aquatic product cultivation, so it is necessary to introduce external water sources intermittently, which affects the observation and analysis of experimental data, resulting in the final data results to a certain extent. error problem
