Towed plankton imager and towed plankton imaging system

Abstract

The invention provides a towed plankton imager and an imaging system. The towed plankton imager comprises an imaging cabin component, a light source cabin component, an optical support, and a power supply module. The light source cabin component comprises a second guide cover, a light source cabin body and a second rear cover, a second window disposed on one side of the light source cabin body is equipped with a second light transmission window, a light source unit installed in the light source cabin provides a lighting light source through a second light transmission window, the imaging cabin component consist of a first guide cover, an imaging cabin body and a first rear cover, a first window disposed on one side of the imaging cabin body is equipped with a first light transmission window, and an imaging unit disposed in the imaging cabin can acquire plankton image photos through the first light transmission window. The towed plankton imager provided by the invention can provide a lighted area through the light source cabin component, and acquire the image photos of plankton in the lighted area through the imaging cabin component, thus realizing identification of zooplankton, also the operation is convenient and the structure is simple.

Description

technical field [0001] The invention relates to the technical field of plankton detection, in particular to a towed plankton imager and a towed plankton imaging system. Background technique [0002] At present, for marine microscopic bacteria and algae, underwater flow cytometry and chip hybridization technology are mainly developed internationally to detect algae and microbial diversity; for large fish and shrimp, underwater optical imaging or acoustic imaging technology is used to identify species and diversity. However, the development of zooplankton detection technology is very weak. Only in recent years, ZOOVIS was developed by the University of Maryland and its cooperation, which can be used for in-situ observation of underwater zooplankton. There is currently no commercial product in the world. [0003] The samples obtained by traditional zooplankton sampling equipment, such as nets and water pump sampling, are usually integrated in space (such as from the bottom to ...

Problems solved by technology

However, the development of zooplankton detection technology is very weak. Only in recent years, ZOOVIS was developed by the University of Maryland and its cooperation, which can be used for in-situ observation of underwater zooplankton. There is currently no commercial product in the world.

[0003] The samples obtained by traditional zooplankton sampling equipment, such as nets and water pump sampling, are usually integrated in space (such as from the bottom to the surface), and the spatial distribution of zooplankton and juvenile fish at a small scale cannot be obtained, so it is impossible to study zooplankton Interaction with juvenile fish, fragile species such as small hydroids and ctenophores cannot be obtained by simultaneous sampling method, in addition, the identification and technique of zooplankton are time-consuming, so continuous sampling is difficult
