Abstract

The invention provides a method for marking a fish individual. A dorsal fin position, a pectoral fin position, a pelvic fin position and a tail fin position of the individual are punched and marked, holes at different positions represent different figures, and the sum of the figures represented by the holes is a serial number of the fish individual, thereby achieving a marking range from 1 to 4999. The marking method can achieve permanent marking of the fish individual, is good in safety, high in marking efficiency and low in cost, accordingly meets the requirements of common fish breeding and scientific experiments, only needs a pair of punching forceps and is especially suitable for marking of fish individuals under the hard conditions outdoors.

Description

A kind of method of fish individual mark

Technical field

The invention belongs to the fish genetic breeding technical field, relate in particular to a kind of method of fish individual mark.

Background technology

At present, when the fish individuality is carried out mark, normal adopt be marked with the external hanging type mark; Promptly at the plug-in label that certain has a given shape of fish body in order to identification, mainly contain Floy mark and T phenotypic marker, disclosed the mark of listing (seeing patent application document 201010267335.1) that is used for the nucleus fish in the prior art; Fish metal wire mark (seeing patent application document 201110329502.5); This labeling method is prone to tangled by fishing net, or itself twines each other between fine rule or the stub, not only can cause losing of mark; And be prone to found and attack by harmful animal, the fish body is caused damage or influences its normal activity.Also have a kind of internal mark, the most frequently used is the PIT mark, promptly with syringe the less radio-frequency mark is injected the fish belly chamber; Also disclosed fish otolith fluorescent marker method (seeing patent application document 201110172710.9) in the prior art; This labeling method individual mark is effective; Also can alleviate the damage of fish body, improve labeling effciency simultaneously, minimum to the breeding process influence of fish; But its cost is higher, and generally hour carries out mark fish.

In order to reduce cost, can satisfy the requirement of fish breeding again, the present invention provides a kind of method of fin punching that adopts to carry out mark, not only can reduce cost, and improves labeling effciency, does not also influence breed, and this type of research does not appear in the newspapers so far.

Summary of the invention

The technical problem that solves: the objective of the invention is to overcome the deficiency that exists in the prior art, a kind of new method of fish individual mark is provided.

Technical scheme: through carry out individuality punching mark at fish dorsal fin, pectoral fin, abdomeinal fin and 4 positions of tail fin; Different digital is represented in the hole of diverse location; The fin of each position characterizes 1,000 kilobit of numeral respectively thus, and the digital addition that each hole characterized is the individual numbering of fish.

As further improvement of the present invention, specifically punching scheme is seen table 1, but visible all numbers with this method mark 1 ~ 4999.

The punching scheme of table 1 fin

As further improvement of the present invention,, the fish body weight carries out mark when being about 100g.

The present invention provides the individual labeling method of fish to can be used for the application in fish breeding and the scientific experimentation.

Beneficial effect:

Carry out the fish individual mark with labeling method provided by the present invention, can realize the permanent marker that fish are individual, no matter be that juvenile fish or adult fish all can carry out mark, label range is wide, can satisfy general fish breeding, protect and plant and other scientific experimentation.This labeling method safety simultaneously is good, and labeling effciency is high, and cost is low, can not lose because of growth and the motion of fish, so applicability is very wide, and its need one are adapted at carrying out under the open-air arduous condition individual mark of fish to perforating plier equally.

Embodiment

Embodiment 1

Below just be illustrated to individual mark in the carp family selective breeding.

(1) seed selection is more than or equal to carp or the adult carp of 100g, with to be marked.

(2) right hand is held marking pincers, and carp is carried out individual mark, in general, successively according to kilobit, hundred, ten with an order of position to the fin mark that punches, see table 1;

(3) on the basis of (2), mark-sense, and record.

(4) on the basis of (3), according to carp breeding and test demand, carry out individual growth traits in different time points and measure, and corresponding with individual mark.

Comprehensive above step, we can obtain, a kind of new method of fish individual mark; Through carry out individuality punching mark at fish dorsal fin, pectoral fin, abdomeinal fin and 4 positions of tail fin, can realize 1 ~ 4999 label range, thereby satisfy general fish breeding and scientific experimentation requirement; Cost is low, and safety is good, and labeling effciency is high; Its need one are adapted at carrying out under the open-air arduous condition individual mark of fish to perforating plier equally.

Claims

1. the method for a fish individual mark is characterized in that: through carry out individuality punching mark at fish dorsal fin, pectoral fin, abdomeinal fin and 4 positions of tail fin, different digital represent in the hole of diverse location, and the digital addition that each hole characterized is the numbering of fish individuality.

2. according to the method for the said fish individual mark of claim 1, it is characterized in that: specifically punching scheme does

1 hole is made a call in the upper end of tail fin, represents 5; 4 holes are made a call in the lower end, and a hole represents 1;

The left end of abdomeinal fin is made a call to 1 hole, represents 50; Right-hand member is made a call to 4 holes, and a hole represents 10;

The left end of pectoral fin is made a call to 1 hole, represents 500; Right-hand member is made a call to 4 holes, and a hole represents 100;

Dorsal fin is made a call to 4 holes, and a hole represents 1000.

3. according to the method for claim 1 or 2 said fish individual marks, it is characterized in that: when the fish body weight is about 100g, carry out mark.

4. according to the method for the said fish individual mark of claim 2, it is characterized in that: but all numbers between this method mark 1 ~ 4999.

5. the application of method in fish breeding and scientific experimentation of claim 1 or 2 said fish individual marks.
