Multi-station copepod zooplankton culture device and culture method thereof

Abstract

The invention relates to a multi-station copepod zooplankton culture device, which comprises a water storage tank and a water supply pipeline connected with the water storage tank, the water supply pipeline is connected with at least one incubator, and the incubator is provided with a bait box and a collection pipeline, The incubator is connected with the water storage tank through the water return pipeline, and the water storage tank is provided with a water inlet pipeline, a drainage pipeline, an acidifier and a temperature sensor, each pipeline is equipped with a valve, and the cultivation device also includes a control box. The same water storage tank is combined with the structural design of multiple incubators to realize the experimental method of the multi-station incubator in the same water area. It is possible to conduct comparative experiments on different copepods in the same water area or different bait delivery methods for the same species of copepods, ensuring that the comparative experiments water quality consistency. At the same time, the cultivation efficiency is improved and the cost of cultivation equipment is reduced. The water storage tank realizes the internal circulation and external circulation mode of the cultivation environment, renews the water body of the whole water area, ensures the cultivation water quality, and ensures the cultivation effect and survival rate of copepod zooplankton.

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...

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
