Abstract

The application relates to the field of aquatic organism measuring equipment. A device for rapidly identifying Euphausia superba and measuring biological characteristic parameters comprises a main box body, the top of the main box body is a measuring plate, at least three hollowed-out areas are arranged on the measuring plate in sequence, and a scale unit is arranged on the hollowed-out areas; the scale unit comprises a base plate, and a reference scale line is arranged on the upper side of the base plate; a slide rail with a left-right direction as a guide direction is arranged at the rear of the main box body; the device further comprises a sliding support which is slidably connected with the slide rail, and a camera and a tablet computer are arranged on the sliding support and connected with the tablet computer. The camera can take photos of the Euphausia superba, and then biological characteristics such as the body length, gender, sexual maturity, body color and feeding intensity of the Euphausia superba are recorded. The sliding support facilitates the sequential recording of the Euphausia superba on different scale units.
