Description
Technical field
The present invention relates to fish morphological index field of measuring technique, in particular to a kind of fish configuration measurement mechanism and its make
Use method.
Background technique
The morphological feature of fish is that fish identify one of mostly important taxology index and fish the most directly give birth to
Long monitoring index.Fish morphometry is the most basic work during resource investigation of fish and aquaculture daily management
Make.However, the problem of often facing following several respects during fish morphometry: one, fish morphological index is more, using measurement
It is heavy that tool measurement measures more time-consuming, workload one by one；Two, the excessively accurate heavy instrument of Portable belt is not set for field investigation
It is standby, usually require that living body rapid survey；Three, when fish somatometry, fish stress reaction is larger, and being easy disorderly to jump, it is out of control to cause,
Escape incident even occurs, influences measurement efficiency；Four, fish form of diverse, measuring tool adaptability is poor, influences measurement essence
Degree；Five, the hard thorn of part fish (such as Chang section fish) or hard spine are toxic, are easy to stab operator in measurement process, cause severe pain.
In order to solve the problems, such as the worked fish of fish morphometry in heavy, there is scholar to propose a kind of fish figure measurement
Device can settle the morphological indexs such as measurement Fish length, body height at one go, and precision is higher.But the measuring device is unsuitable
Field resource investigation of fish, especially development somatometry.In order to adapt to field work, have scholar propose with it is foldable just
Functional measurement device is taken, this device has certain flexibility, carries convenient for field, but measurement index is limited, and without corresponding
Anti-escape and protective device.Then, some scholars propose to solve the problems, such as that measurement process Mesichthyes escapes with anti-escape
The measuring device of net, but the problem of this device still has narrow scope of application.Then there is scholar to propose one kind again to be convenient for
The station of fish injection and measurement, this device very good solution escape problem of measurement process Mesichthyes, and can fit
The long measurement of the body of various figure fish is answered, but this station measurement index is limited, and there are still easily toxic in operating process
The problem of stickleback class is stabbed.Generally speaking, effectively comprehensive solution, fish are not obtained the problem of fish measurement process
The work of class morphometry, has the somatometry of the fish of telson in particular for Chang section fish etc., is still further improved
It is perfect.

The long DATA REASONING of body；
S4, the distance between two fixed links 41 are read by ranging tool, thus the high DATA REASONING of perfect aspect；
S5, the fish body to be measured highest point of fish body to be measured when measuring chamber that lies low is read by the scale in fixed link 41 arrive
The distance for measuring chamber upper surface, so that the wide DATA REASONING of perfect aspect, fish body to be measured is replaced.
Preferably as one kind of the invention, in step S1, after holding clear water in measurement chamber, anesthetic is added toward clear water.
Embodiment 1:
Referring to Fig. 2, there is the fish pierced firmly with poison using a kind of fish configuration measurement mechanism measurement Chang section fish of the present invention etc.
When class (the present embodiment measures Pelteobagrus fulvidraco), following steps progress can refer to:
1) a small amount of clear water is held in measurement chamber, decides whether to add into clear water according to the active degree of Pelteobagrus fulvidraco few
Anesthetic is measured, if Pelteobagrus fulvidraco to be measured is excessively active, adding a small amount of anesthetic makes it get off, and avoids its hard puncture of band poison
Hurt survey crew, if Pelteobagrus fulvidraco to be measured is quieter, without adding anesthetic, then uses diddle-net by Pelteobagrus fulvidraco to be measured
It puts into measurement chamber, makes scale starting point of its head towards measuring scale 2；
2) spacing between two fixed links 41 is adjusted by sliding slip rope set 45, Pelteobagrus fulvidraco is made to be located at two fixed links 41
Between；
3) the fixed Pelteobagrus fulvidraco of hand, another hand push move baffle 3, make scale starting point and the Pelteobagrus fulvidraco of measuring scale 2
Rhynchodaenm alignment, then adjusts the position of fixed bracket and fixed link 41, make two fixed links 41 respectively with the back of Pelteobagrus fulvidraco most
Between two pectoral fins that high point and the minimum point alignment of abdomen, i.e. two fixed links 41 are just stuck in Pelteobagrus fulvidraco pierce firmly, to realize
Then fish body control reads the rhynchodaenm of Pelteobagrus fulvidraco to the distance of tail portion, thus the long DATA REASONING of perfect aspect by measuring scale 2；
4) the distance between two fixed links 41 are read by the scale on crossbeam 42, so that the high data of perfect aspect are surveyed
Amount；
5) the Pelteobagrus fulvidraco highest point of Pelteobagrus fulvidraco when measuring chamber that lies low is obtained using the tools such as horizontal ruler correspond to fixed link 41
On scale, so that the wide data of the body for obtaining Pelteobagrus fulvidraco, the wide DATA REASONING of perfect aspect, Pelteobagrus fulvidraco is replaced and is started under
The measurement of one Pelteobagrus fulvidraco.
Embodiment 2:
It can refer to following steps when measuring flat-sided type fish using a kind of fish configuration measurement mechanism of the present invention referring to Fig. 3
It carries out:
1) a small amount of clear water is held in measurement chamber, then fish body to be measured to be measured is put into measurement chamber with diddle-net, is made
Its head is towards the scale starting point of measuring scale 2；
2) spacing between two fixed links 41 is adjusted by sliding slip rope set 45, fish body to be measured is made to be located at two fixed links
Between 41；
3) the fixed fish body to be measured of a hand, another hand push move baffle 3, make the scale starting point of measuring scale 2 and fish to be measured
The rhynchodaenm of body is aligned, and then adjusts the position of fixed bracket and fixed link 41, make two fixed links 41 respectively with fish body to be measured
Then back highest point and the minimum point alignment of abdomen read the rhynchodaenm of fish body to be measured to the distance of tail portion by measuring scale 2, thus
The long DATA REASONING of perfect aspect；
4) the distance between two fixed links 41 are read by the scale on crossbeam 42, so that the high data of perfect aspect are surveyed
Amount；
5) fish body to be measured is obtained using the tools such as horizontal ruler to lie low the corresponding fixation in highest point of when measure chamber fish body to be measured
Scale on bar 41, so that the wide data of the body for obtaining fish body to be measured, the wide DATA REASONING of perfect aspect, fish body to be measured is replaced simultaneously
Start the measurement to next fish body to be measured.
Fish configuration measurement mechanism provided by the invention has fully considered the physical characteristic of Chang section fish, by utilizing fixation
The malicious hard thorn of the fixed pectoral fin band of bar 41, escapes and stabs event caused by capable of effectively avoiding fish body to be measured from struggling, to carry out accurately
Measurement.41 flexibility of moveable fixed link is extremely strong, operates convenient and efficient, and fixed bracket is detachable, carries convenient for field.In addition to
Outside measurement for Chang section fish, the present invention can be also used for the measurement of other figure fish (such as lateral deviation type fish), and lead to
Measuring scale 2 is crossed, with graduated crossbeam 42 and graduated fixed link 41 is set and realizes variform index measurement.In addition,
Application method provided by the invention is easy to operate, efficient, and step is few, measuring speed is high-efficient.
Embodiments of the present invention are explained in detail above in conjunction with attached drawing, but the present invention is not limited to above-mentioned embodiment party
