Problems solved by technology

[0003] In the traditional in vitro tagging operation, there is currently no special device that is convenient for in vitro tagging operations. There is no special operating platform for the usual tagging operations. Most of them use basins and barrels filled with water to hold fish fry, javelins, and labels to be marked. and other tools are scattered and taken on the spot; in order to improve the efficiency of marking, the traditional method is to anesthetize the marked fry in the operation tank first, and then carry out the tagging operation on the marked objects one by one

Embodiment 1

[0037] The present invention as figure 1 , figure 2Shown, a kind of operating device of in vitro listing sign discharge fry, this device comprises tank 6, operating platform 2, support base 1, ear-shaped operating platform, water inlet 7 that water valve is housed and the water outlet 8 that water valve is housed. The water tank 6 is embedded in the operation platform 2, and the embedded depth is about 2 / 3 of the depth of the water tank. The water inlet 7 is installed on the upper side wall of the water tank 6, and the water outlet 8 is installed on the lower side wall of the water tank 6 opposite to the water inlet 7. Position, the water inlet 7 is connected to the water inlet or the water outlet 8 of the previous operating device; the diagonal water inlet and outlet settings can fully exchange the water in the tank 6 and keep the water quality fresh. The combined operating device can be connected according to the sign Fast and flexible assembly of size and number of operat...

Embodiment 2

[0042] The invention is used to carry out in vitro listing and marking operation of black sea bream fry. Black sea bream is a common breeding and releasing object in my country, and it is an important economic species for seawater breeding, and it is also a fish that is often used for in vitro listing. The black sea bream seed specification that chooses in the present embodiment is body length 55-65 mm, and the sign plate that adopts is plastic oval signboard (POTs) (0.1mm * 8mm * 15mm, 0.01g), and signboard utilizes the marking gun of 003 model to make onto juvenile black bream. The specific operation method is to pass the "I" shaped plastic needle (length 10mm, weight 0.02g) made by POTs with a marking gun through the round hole (diameter 1.5mm) on the sign, and then puncture and fix it on the third to fifth dorsal fin of the fish. In the muscle about 5mm below the fin spine base.

Abstract

The invention provides a working device and method of external tagging and marking of released fry. Specifically, the device comprises at least one group of a first operation mechanism and a second operation mechanism which are arranged in serial connection, wherein the first operation mechanism and the second operation mechanism have a same structure, and each comprises a supporting seat and an operation platform arranged on the supporting seat; a concave downward water tank is arranged in the center of each operation platform; a boss is arranged on a connecting section between the water tank and the operation platform; and an included angle between the tangent direction of a line from the boss to the operation platform and the operation platform is in a range of 90-160 degrees. The invention also provides the working method of external tagging and marking of the released fry by using the working device of external tagging and marking of the released fry. Without using anesthetics, the method ensures the marking efficiency, reduces the death rate of marked fry in the marking process, and meets the above requirements in prior arts.

Description

technical field [0001] The invention belongs to the operation technology of releasing fish fry, and relates to an operation device and method for releasing fish fry with a sign outside the body. Background technique [0002] During the implementation of multiplication and release of fishery resources conservation or related scientific research, some fish fry are usually selected for marking or marking, so as to track, monitor and evaluate the implementation effect of multiplication and release. The tagging technology is an in vitro marking method that uses a puncture method to puncture and hang a sign with release and tracking monitoring information on the body of the subject to be marked. Its application in the field of fishery enhancement and release has the advantages of low cost, group or even individual identification, eye-catching signs and easy to be found, etc. It is a marking technology that is often used in this field. Simultaneously, because this marking techniqu...
