Abstract

The utility model relates to a signboard, in particular to a signboard for marking adult crabs. A signboard body comprises a marking area, a partitioning line, counting holes and fixing holes, and is characterized in that the signboard body is trapezoidal, and each angle of the signboard body is a circular-arc chamfer angle; the marking area is divided into an upper part and a lower part by the partitioning line, the part above the partitioning line accounts for 1/3 of the marking area, and the part below the partitioning line accounts for 2/3 of the marking area; the fixing holes are formed, 3mm away from the front edge and the rear edge, in the long-axis central line of the signboard body, and each fixing hole is a 3mm*2mm rectangular round-angle hole; the counting holes which are vertical to the partitioning line are arranged in lines. According to the signboard, an abacus carry rule is used as a counting rule, and holes are drilled for counting in the 1cm<2> signboard body, so that nearly 10,000 marks can be obtained; meanwhile, approximately infinite marks can appear after the color of the signboard body, the color of the partitioning line and the shape as well as the counting holes of the signboard body are combined, so that the signboard can be used for large-scale marking.

Description

A kind of Sign Board that becomes crab mark for crab class

Technical field

The utility model relates to a kind of Sign Board, specifically a kind of Sign Board that becomes crab mark for crab class.

Background technology

When selecting the research of breeding project, labeling technique is the basic key technology of carrying out aquatic livestock breeding research.Only have by individual, family (or colony) are carried out to mark, could carry out same environment cultivation comparative trial, eliminate the impact of environment on growth, guarantee to calculate the accuracy of breeding value, the important economical trait that can improve fast seed selection animal is as the performance of growth rate etc.Especially by individual mark technology, in correct directional cross, reach science breeding, prevent that the aspects such as inbreeding depression from playing a key effect.

The existing labeling method being used in shell-fish has: cut appendage (ablation of body parts), tatoo (tattooing), deep tissues vital staining (submersion in vital dyes), line mark (nylon filament tag or vinyl tubing tag), fluorochrome mark (visible implant elastomer, VIE), fluorescent board mark (visible implant alphanumeric, VIalpha), eye mark (eye tag) etc.

Because shelling in crab class process of growth is frequent, so be fluorochrome mark with regard to the family of crab class or the optimum mark method of colony at present.Fluorochrome mark is owing to adopting muscle injection mode, preferably resolve the mark obscission that shelling causes, but because depending on only several color fuel, this labeling method carries out composite marking animal, maximum mark limited amount is (according to color and injection site, number of combinations only can reach 100～200), its discrimination height also depends on the depth of animal body surface color simultaneously, therefore this labeling method only limits to the tag application to family (colony) at present, and the cost of fluorochrome mark is higher.Have at present in addition the application of eye mark and fluorescent board in shrimps mark, but crab class because optic stalk is shorter, eye is marked and is easily come off, crab shell color is darker, fluorescent board mark rate and read rate are not high, and perform the operation and also can cause crab class lethality to increase, and affect directed breeding rate.

Utility model content

In order to solve above-mentioned technological deficiency, what the utility model provided that a kind of mark discrimination is high, mark lethality is low, marker material is with low cost, tagging is easy to search becomes the notice plate of crab mark for crab class.

The purpose of this utility model is achieved in that a kind of Sign Board that becomes crab mark for crab class, board body comprises that mark zone and fixing hole mark zone are divided into upper and lower two parts by cut-off rule, by punching counting in this two parts region, counting rule is rechoning by the abacus carry rules.Board body is nylon products, and board shape is trapezoidal and each angle of board body is circular arc chamfering.On board long axis of body center line, apart from 3mm place, edge, front and back, respectively establish 1 fixing hole, fixing hole is 3mm * 2mm rectangle fillet hole.Mark zone is divided into upper and lower two parts by cut-off rule, and the above part of cut-off rule accounts for 1/3 of mark zone, and the following part of cut-off rule accounts for 2/3 of mark zone.In marked region, by punching, count, cut-off rule is with the counting hole representative " 1 " of lower area, the counting hole representative " 5 " in the above region of cut-off rule, counting hole vertical divider is in column to be got, individual, ten, hundred of row representatives, each column count hole represents that numeral adds up to the figure notation of Sign Board representative.

After the shape of the color of sign board board body, the color of cut-off rule, board body and counting hole combination, can become different marks.

Sign Board is fixed on crab class foot of a chela carpopodium or meropodium through after fixing hole with nylon cable tie or cord in use.

The utility model has the advantage of that cost of manufacture simple in structure is cheap, nylon board body is durable in use, is not subject to crayfish culture environmental influence, after especially using nylon cable tie fixing, is close to the crab class foot of a chela, similar " wrister " more difficult coming off after Sign Board is fixing.The utility model is usingd rechoning by the abacus carry rules as counting rule, at 1cm ²board body on can beat counting hole 3～4 row, reference numerals can reach nearly 10,000, after color, the color of cut-off rule and the shape of board body of board body and counting hole combination, can occur being close to unlimited mark number simultaneously, and can carry out extensive mark use completely.

Accompanying drawing explanation

Fig. 1 is schematic diagram of the present utility model.

Fig. 2 is an illustration of the present utility model, representative " 276 ".

Embodiment

Referring now to accompanying drawing 1, be described as follows: the utility model is a kind of Sign Board that becomes crab mark for crab class in conjunction with the embodiments, board body comprises mark zone 1 and fixing hole 4, mark zone 1 is divided into upper and lower two parts by cut-off rule 2, by 3 countings that punch in this two parts region, counting rule is rechoning by the abacus carry rules.The utility model board body is nylon products, and board shape is trapezoidal and each angle of board body is circular arc chamfering.On board long axis of body center line, apart from 3mm place, edge, front and back, respectively establish 1 fixing hole 4, fixing hole 4 is 3mm * 2mm rectangle fillet hole.Mark zone 1 is divided into upper and lower two parts by cut-off rule 2, and cut-off rule more than 2 partly accounts for 1/3 of mark zone 1, and cut-off rule part below 2 accounts for 2/3 of mark zone 1.In 1 territory, mark zone, by punching 3, count, cut-off rule 2 is with hole 3 representative " 1 " of lower area, and the hole 3 in cut-off rule 2 above regions represents " 5 ", and vertical divider 2 is in column in hole 3 gets, individual, ten, hundred of row representatives, each is listed as hole 3 and represents that numeral adds up to the figure notation of Sign Board representative.For example the figure notation of Fig. 2 representative is " 276 ".With nylon cable tie (or cord), through after two fixing holes 4 of sign board, sign board is fixed around crab class foot of a chela carpopodium or meropodium, sign board, between nylon cable tie and the foot of a chela, has just completed the mark to a crab class.

It is more than the most basic embodiment of the utility model, the quantity of mark can also be by the color of composite marking board board body, the color of cut-off rule, the shape of board body and the mode of counting hole form different marks as required, reach the object that increases marker number, such as board shape can also be triangle.
