Description
Technical field
This utility model relates to aquaculture field, in particular for quickly differentiating the instrument of mandarin sturgeon sex.
Background technology
Mandarin sturgeon is a kind of large-scale anadromous migration Fish, be in the existing Fish in the world the most rare the most original kind it
One, mandarin sturgeon Ye Shi China one-level lays special stress on protecting wild animal, enjoys the good reputation of " giant panda in water ".During the sexual maturity of mandarin sturgeon
Between longer, the female mandarin sturgeon for the first time sexually matured time is generally 14～26 years (average 18 years), and male mandarin sturgeon is for the first time
The sexually matured time is generally 8～18 years (average 12 years).In the breeding process of mandarin sturgeon, female owing to lacking effective discriminating
Male method, all of fish was all raised together with together before reaching age at sexual maturity；Only when proximity maturation age, gonad
Male and female could be distinguished by the technology such as B ultrasonic, puncture when feature is obvious.When utilizing B ultrasonic technology to differentiate mandarin sturgeon adult fish gonad, right
Adult fish gonad development require higher, only when in B ultrasonic image male and female gonad feature clearly in the case of could effectively enter
Row differentiates, and the detectability of the method is relatively low, requires higher to the technology of operator；China is carried out utilizing the method punctured
During sturgeon sex abnormality, it is desirable to when the content feature of puncture acquirement is obvious, (female content typically has obvious graininess ovum grain；
The general white bulk of male content or refining) just can accurately carry out Sex judging.These methods cannot be accurately to low
Age, mandarin sturgeon carried out Sex judging, was unfavorable for that the group structure optimization of mandarin sturgeon artificial cultivation colony and the specific aim of parent fish are cultivated
And species conservation work carry out.
Summary of the invention
Technical problem to be solved in the utility model is to provide the instrument for quickly differentiating mandarin sturgeon sex, and utilizing should
Instrument, can carry out sex abnormality to the mandarin sturgeon of sexual maturity (more than 6 ages) in early days, quickly, efficiently, accurately；Easy to operate, real
Extremely strong by property, meet the demand of sex abnormality in the work such as mandarin sturgeon aquaculture, scientific research.
For solving above-mentioned technical problem, this utility model be the technical scheme is that
For quickly differentiating the instrument of mandarin sturgeon sex, including first handle and second handle, first handle and second-hand
The middle part of handle is flexibly connected by bolt, and the top of first handle and second handle is flared out with vertical in a clamp
The top of angle a, first handle and second handle is respectively fixedly connected with support mouth sheet, and support mouth sheet is positioned at support mouth sheet with the junction of handle
Middle side edge.
The angle of angle a is 15～20 degree.
Support mouth sheet is the square lamellar body of a size of length of side 2 centimetres.
The instrument for quickly differentiating mandarin sturgeon sex that this utility model provides, utilizes this instrument, to sexual maturity in early days
The mandarin sturgeon in (more than 6 ages) can carry out sex abnormality, quickly, efficiently, accurately；Easy to operate, practicality is extremely strong, meet China
The demand of the sex abnormality in the work such as sturgeon aquaculture, scientific research.
By using this utility model to carry out sex identification 36 tail mandarin sturgeons, identify male and female mandarin sturgeon 15 tail altogether, male
Property mandarin sturgeon 20 tail, gonad feature is inconspicuous, it is impossible to mandarin sturgeon 1 tail of differentiation, use this method to the detectability of male and female be
97%。
Accompanying drawing explanation
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings:
Fig. 1 is structural representation of the present utility model, and now two support mouth sheets are in closure state；
Fig. 2 is structural representation of the present utility model, and now two support mouth sheets are in open configuration；
Fig. 3 is block diagram of the present utility model；
Fig. 4 is this utility model embodiment two step 4 schematic diagram at the opening of mandarin sturgeon abdominal incision；
Fig. 5 is the schematic diagram of the external appearance characteristic of the male and female gonad that this utility model embodiment two step 5 is observed.
Detailed description of the invention
Embodiment one
As Figure 1-3, a kind of employing said method carries out mandarin sturgeon sex identification used tool, including first handle 4
With second handle 5, the middle part of first handle 4 and second handle 5 is flexibly connected by bolt 7, first handle 4 and second-hand
The top of handle 5 is flared out with vertical to a in a certain angle, and the top of first handle 4 and second handle 5 is respectively fixedly connected with support
Mouth sheet 8, support mouth sheet 8 is positioned at support mouth sheet 8 middle side edge with the junction of handle.
The angle of angle a is 15～20 degree.
Support mouth sheet 8 is the square lamellar body of a size of length of side 2 centimetres.
The above is only non-limiting embodiment of the present utility model, for the person of ordinary skill of the art,
On the premise of creating design without departing from this utility model and not making creative work, it is also possible to make some deformation and change
Entering, these broadly fall into protection domain of the present utility model.
Embodiment two
A kind of quickly discriminating mandarin sturgeon property method for distinguishing, the method comprises the following steps:
Step 1: supporting temporarily of mandarin sturgeon to be identified prepares: is put in storage pond, holding pond by mandarin sturgeon to be identified and supports temporarily, temporarily
The foster time is 2～3 days, supports period temporarily and stops eating, and ensures the most foster good water water quality；
Step 2: configuration anesthesia liquid；
Step 3: the anesthesia of mandarin sturgeon to be identified: mandarin sturgeon to be identified is put into anesthesia case and carries out anaesthetizing until fish body enters
Enter deep anaesthesia state (deep anaesthesia state can be entered in about 5～8 minutes),
Anesthesia case specification is 4 meters × 2 meters × 1 meter, and total measurement (volume) is 8 cubic metres, puts into 0.5 meter of deep water in anesthesia case,
The water yield is 48 cubic metres；
Step 4: abdominal incision: take out mandarin sturgeon to be identified, slightly biased between the pectoral fin 2 and abdomeinal fin 3 of mandarin sturgeon to be identified
To the side of pectoral fin, along abdomen hone lamella upper limb at the opening 1 that side oddi's sphincteroplasty is 3～4 centimetres, as shown in Figure 4；
Step 5: sex abnormality: utilize special instrument of dehiscing, struts the upper opening 1 cut of mandarin sturgeon to be identified, observes it
The shape of internal gonad, carries out sex abnormality according to the external appearance characteristic of male and female gonad, as it is shown in figure 5,
Female gonads feature: gonad is that spire is branched, has the color characteristics such as yellowish, pink；
Male gonad feature: gonad is divided into some fritters, surface is smooth shape, has the color characteristic such as pale pink, white；
Step 6: wound processes: sews up the wound of the mandarin sturgeon completing sex abnormality, and carries out anti-inflammatory treatment；
Step 7: the recovery after discriminating and recovery: by step 6 through treatment after mandarin sturgeon flowing water culture pond immediately in enter
Row recovery, and note following the tracks of the recovery situation observing wound in the cultivation in later stage, can be recovered treatment if desired；
I.e. complete the quick discriminating of mandarin sturgeon sex.
In step 4, opening 1 position of incision is between the pectoral fin 2 of mandarin sturgeon and abdomeinal fin 3, and between pectoral fin 2 and abdomeinal fin 3
Distance d of center line 6 is 5～15 centimetres.
The discriminating operating process of step 5 controlled within the Anesthetic safety time of 5 minutes.
