The invention discloses a
living body lantern fish collecting net and a collecting method, and belongs to the technical field of
marine organism living body sampling, the
living body lantern fish collecting net comprises a cover net, the bottom of the cover net is movably connected with a bottom net, the center of the top surface of the bottom net is fixedly connected with a first heavy hammer, the first heavy hammer is connected with take-up equipment through a
mooring rope, and a monitoring mechanism is arranged on the outer side of the cover net; the two sides of the cover net are respectively provided with a self-
locking mechanism, the self-locking mechanisms are matched with the bottom net, and a light trap is arranged in the cover net. During operation, the shipborne fish finder of the
fishing boat detects the target
water depth of the
lantern fish, the collecting net sinks to the target
water layer along with the
mooring rope for
trapping, the lantern fish is trapped into the net, the
mooring rope is rapidly lifted, and after the bottom net is clamped into the self-locking structure at the bottom of the cover net, the bottom net begins to slowly move upwards to transfer the lantern fish. The collecting net is collected and released through the mooring rope, low-disturbance capturing, physiological state maintaining and real-time image monitoring can be achieved, collecting and transferring of living lantern fishes are facilitated, and the
survival rate of the living lantern fishes is increased.
