Multi-station copepod culture device and culture method thereof

Abstract

The invention relates to a multi-station copepod culture device. The multi-station copepod culture device comprises a water storage tank and a water feeding pipeline connected with the water storage tank, wherein the water feeding pipeline is connected with at least one incubator; the incubator is provided with a bait box and a collection pipeline; the incubator is connected with the water storage tank through a water returning pipeline; the water storage tank is provided with a water inlet pipeline, a water discharging pipeline, an acidifying machine and a temperature sensor; each pipeline is provided with a valve; and the culture device further comprises a control box. A structural design that the same water storage tank is combined with the plurality of incubators is adopted so that an experiment method of a multi-station incubator in the same water region is realized; and a contrast experiment can be carried out on different bait feeding manners of different copepods or same copepods in the same water region, so that the consistency of water quality of the contrast experiment is guaranteed. Meanwhile, the culture efficiency is improved and the cost of culture equipment is reduced. The water storage tank realizes internal circulation and external circulation manners of a culture environment and a water body of the whole water region is updated; and the culture water quality is guaranteed, and the culture effect and survival rate of the copepods are guaranteed.

Description

technical field [0001] The invention relates to the field of marine microorganism cultivation equipment, in particular to the field of mechatronics for marine organism cultivation, in particular to a multi-station copepod zooplankton cultivation device. Background technique [0002] Copepod zooplankton is an important part of the marine ecosystem, a secondary producer in the biological chain, and plays an important role in maintaining the balance and stability of the marine ecosystem. At the same time, because it is rich in unsaturated fatty acids, it is a high-quality bait at the first level of the food chain, and is suitable as an opening bait for fish and shrimp. Zooplankton are generally small and have a short life cycle, and are easily affected by changes in the external environment. Wild collection is far from meeting the needs. Therefore, the large-scale cultivation of marine zooplankton as bait has always been a hot spot in aquaculture. [0003] In order to realize...

AI Technical Summary

Problems solved by technology

However, this equipment cannot achieve multi-station simultaneous cultivation, and cannot realize the circulation and filtration of internal culture water

[0005] Chinese patent CN 101243781 A is a zooplankton culture device, which discloses an integrated incubator that is easy to move, including a culture part fixed to a bracket, a flushing part and corresponding pipelines, but this culture can only be realized in one batch cultivation, and the adjustment of water temperature and acidity is inconvenient, and automatic control cannot be realized

[0006] The unit efficiency of the existing culture system is still low, and the collection of zooplankton and their eggs is inconvenient, resulting in a low survival rate of late eggs and larvae
