Embodiment

[0012] Example: refer to Figure 1 to Figure 3 , the device for determining the spawning ground in deep water includes a cylindrical housing 1 with a rear cover 2, wherein: a waterproof airbag 16 is arranged in a folded manner in the housing 1; an ignition coil 15 is arranged in the waterproof airbag 16; A control circuit 14 capable of timing on demand and a battery 13 are connected; a solid detonator is arranged near the surface of the ignition coil 15 . The ignition coil 15 detonates the solid detonating agent at a specific time under the control of the timing control circuit, after the waterproof airbag 16 is inflated rapidly, the back cover 2 is pushed back, and the cylindrical housing 1 is separated. An identification mark is set on the waterproof air bag for determining the discharge information. The whole waterproof air bag 16 floats to the sea surface, and researchers can infer the position of the spawning ground according to the release information for research. The...

Abstract

The invention discloses a device for determining a deepwater spawning site. The device comprises a cylindrical shell with a back cover; a waterproof air bag is arranged in the shell in a folding mode; an ignition coil is arranged in the waterproof air bag; a control circuit and a battery capable of being timed according to needs are connected to the ignition coil; solid ignition materials are arranged nearby the surface of the ignition coil. The ignition coil is controlled by the timed control circuit to ignite the solid ignition materials at specific time, and after the waterproof air bag is rapidly inflated to swell, the back cover is ejected open and breaks away from the cylindrical shell. Identification marks are arranged on the waterproof air bag to determine discharging information. The whole waterproof air bag floats on the sea level, and a research worker can deduce the position of the spawning site according to the discharging information for researching. The device has the advantages that GPS positioning recording is achieved, floating is carried out in a timing mode to mark the geographic positions, the structure is compact, and mass marking is convenient.

Description

technical field [0001] The invention relates to an intelligent aquatic biological marker, in particular to a device for determining a spawning ground in deep water. Background technique [0002] Marking-recapture technology is one of the applied technologies in the basic research of aquatic life behavior, biology and ecology. It refers to marking the aquatic organisms captured or artificially bred in natural waters and then returning them to natural waters. When recapturing, according to relevant records and biological data, their swimming routes, moving speeds, distribution ranges and growth patterns can be studied. Biological characteristics such as the age, growth condition, and feeding characteristics of the fish species. At present, the aquatic biomarker technology at home and abroad is mainly divided into two categories: in vitro labeling method and in vitro and in vivo labeling method. In vitro labeling methods include tagging, fin cutting, and branding. In vivo lab...
