Description

TECHNICAL FIELD

[0001] The present application relates to the field of aquatic organism measuring equipment, in particular to a characteristic parameter measuring plate. BACKGROUND

[0002] Antarctic krill is a typical crustacean zooplankton, which is widely distributed around the Antarctic continent. Among all the multicellular animals known on earth, the biomass of Antarctic krill is the largest, and its resource amount is estimated to be 3.0x10 8 ~ 5.0x10 8 t. At the same time, they are also the key link of the material and energy flow in the entire Southern Ocean ecosystem, and they are not only important herbivorous animals in the Southern Ocean, but also provide food sources for fish, whales, seals, penguins, seabirds, etc. Antarctic krill has a high content of lipid substances, rich in nutritious long-chain polyunsaturated fatty acids, and is known as the largest animal protein bank in the world, and is also rich in mineral elements and carotene, etc. Therefore, the development value of Antarctic krill is very huge.

[0003] In the process of developing and utilizing Antarctic krill resources, according to the relevant requirements of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), the species of the caught Antarctic krill need to be identified, and the body length and gender characteristics of a certain number of net times of Antarctic krill need to be measured, counted and submitted on site. CCAMLR requires at least 200 Antarctic krill to be measured each time, in addition, in the process of biological scientific research of Antarctic krill, a large number of body length, gender, sexual maturity, body color, feeding intensity and other biology of Antarctic krill also need to be measured and recorded. According to the requirements of CCAMLR, each fishing boat needs to be equipped with 1-2 scientific observers, and the work load is huge. The Antarctic environment is harsh, which makes the Antarctic krill fishing boat always in a state of shaking, increasing the difficulty of work. In addition, the individual of Antarctic krill is small, and currently a vernier caliper is used to measure the body length of Antarctic krill, and the vernier caliper needs to be adjusted again after each measurement. When identifying the species, gender, body color and feeding intensity of Antarctic krill, human subjective factors are often relied on, and the above factors seriously affect the measurement efficiency and accuracy. Therefore, it is urgent to invent a new Antarctic krill biological characteristic rapid identification and measurement device to improve the efficiency and accuracy of Antarctic krill species identification and biological measurement.
