Abstract

The utility model relates to a connection tag primer for fish tagging, which comprises three parts of a front end part (1), a middle end (2) and a tail end (3). The front end part (1) is an arrow (4),holes (6) are opened on the middle end (2), the tail end (3) is provided with a hollow cylindrical hole (7). The utility model is applicable to be used for tuna and sailfish tagging, has less damageto an experimental subject, and can be put into a fish body rapidly. In addition, the connection tag primer can decrease the off-tag probability of a separation type satellite tag greatly, and reducethe damage to a tagging subject, the connection tag primer is beneficial to developing the research work smoothly, and increase the success rate of tagging.

Description

Fish tag is released with connecting the sign primer

Technical field

The utility model belongs to the biology of fishes technical field, relates to a kind of fish tag of carrying out and releases with connecting the sign primer.

Background technology

Tagging is meant and will fishes on the aquatic animal bolt of acquisition a sign board in the natural waters or do to go up mark or load onto electronic marker, put back to marine free living again, carry out the research that fish migration habit, resource reserves, fishing ground form contents such as mechanism according to the release record and the record of recapturing then.At present, the fish tag method of releasing mainly contains: (1) body surface charactery; (2) body internal labeling method; (3) biotelemetry; (4) chemical substance notation; (5) archives formula notation in the body; (6) separate type satellite notation.PTT-100 Archival Pop-up Tag is one of separate type satellite sign, and this kind sign board can send signal automatically, and this signal can and be followed the tracks of by satellite acquisition, and to the regular period, sign board can come off automatically; This denotation approach has been widely used in studying the migration habit of large-scale migration aquatic animal and spawning ground distribution etc., relates to aquatile and comprises mammal, green turtle, shark and tuna etc., and obtained success.

At present, utilizing separate type satellite sign to carry out the tuna tagging both at home and abroad connects with indicating that primer mainly is divided into following three types (as Fig. 1,2,3), material is generally metal or plastics, the one end is generally the tip shape, can penetrate in the tuna body, the other end leaves an aperture, and utilizing high duty metal line or linen thread to pass aperture can link to each other with separate type satellite sign.These sign primers generally need or carry out minor operation by boost motor when inserting in the tuna body, and are consuming time longer, and it is bigger to take off the mark probability.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of fish tag and releases with connecting the sign primer, and is long to insert the sign time in the solution prior art, and takes off the target defective easily.

A kind of fish tag is released with connecting the sign primer, is divided into leading section, intermediate ends and three parts of tail end, and described leading section is an arrow, has the hole on the described intermediate ends, and described tail end has the cylindrical hole of a hollow.

The wedge angle of described arrow tail end has chamfering backward.

Vertical setting of types has two holes on the described intermediate ends.

The afterbody of described tail end has an outside bent angle.

Beneficial effect

The utility model is applicable to tuna, sailfish class tagging usefulness, little to the experimental subjects damage, can insert in the fish body fast, and can reduce separate type satellite sign greatly take off the mark probability, reduce damage to the tagging object, help carrying out smoothly of research work, improve the tagging success rate.

Embodiment

Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.

Embodiment 1

As shown in Figure 4, a kind of fish tag is released with connecting the sign primer, be made by stainless steel, total length is 50mm, body width is 6mm, be divided into leading section 1,3 three parts of intermediate ends 2 and tail end, described leading section 1 is an arrow 4, about 60 degree of arrow wedge angle, two wedge angle 5 length of arrow are 20mm, end has chamfering backward, vertical setting of types has two holes 6 on the described intermediate ends 2, the aperture is 2mm, is 20mm near first aperture at arrow position apart from the arrow end, and second aperture and distance first aperture are 1mm, described tail end 3 has the cylindrical hole 7 of a hollow, the length of hollow is 15mm, and width is 3mm, and the afterbody of described tail end 3 has an outside bent angle 8.

When connecting separate type satellite sign, by auxiliary material such as silicone tube and high-strength polyethylene netting twines, silicone tube (internal diameter 1.5mm) is a medical silicone tube, the internal diameter size just in time can be entangled the lead-in wire that the high-strength polyethylene netting twine becomes the sign primer, connects the about 70mm of silicone tube length of separate type satellite sign and sign primer at last; High-strength polyethylene netting twine diameter is 1.4mm, penetrates silicone tube before the tagging, and an end hitches the aperture at metal derby middle part, and an end hitches separate type satellite sign.

The utility model front end position is processed as arrow shaped, and two tips of arrow have prying slightly, and design helps inserting fast in the fish body by this arrow like this, and the permanently effective fish body that hooks of energy, reduces greatly and takes off the mark probability; Two apertures of middle part processing, aperture size can be passed by the high-strength polyethylene netting twine; Later half position has one section for hollow, can be actual tag and releases and by screwdriver or other boost motors metal derby is inserted in the tuna body fast in the operation; Least significant end has prying slightly, helps metal derby and inserts back difficult drop-off in the fish body; Silicone tube entangles the high-strength polyethylene netting twine as lead-in wire usefulness, connects separate type satellite sign, can guarantee to indicate the intensity of lead-in wire like this, also can reduce because of the injury of friction generation to fish.
