Abstract
The utility model relates to a body parameter measuring device for the fish. The body parameter measuring device can bear weight of the fish. The body parameter measuring device comprises a base board and first, second and third limit members, wherein the base board has a measuring plane, and the three limit members are used for limiting the position of the fish. The body parameter measuring device can simultaneously measure full length, height and weight of the fish, can simplify body parameter acquisition work of fish samples in the laboratory and improves efficiency.
Description
Technical field
The utility model relates to the body parameter measurement mechanism of a kind of fish.
Background technology
Fish are as the larger social animal of a kind of movability, along with the variation in season makes the change of fish self or environment and makes the regional Fish Community Structures also can be along with variation.For example some migration fishes live conventionally in ocean, reach after sexal maturity annual mating period tracing back in groups swim over to rivers and lakes, or conventionally in fresh water, live, reach and fall river after age at sexual maturity and breed in ocean; Also have some fish because the tolerance limit that the variation of temperature exceedes self is found some suitable temperature environments, if fat section the first daytime is in profundal zone activity, swim to shallow water band night, and the autumn and winter dive in deep water crack of stone, or be embedded in mud and pass the winter, and exposes head; Because making some fish not obtain sufficient food, the variation of food factor reduces in a large number, or food too much increases sharply, for example some phytophagous fish in the arrival in summer due to pasture and water riotous growth, its quantity also can increase thereupon, and winter, pasture and water biomass reduced, its quantity also can reduce; Be subject to predator's impact, some fish can because predator in some more in season, quantity reduces; Due to the impact of rugged surroundings, as Various Seasonal has arid, heavy rain etc. all can affect to Fish Communities; In addition, the mankind's overfishing and the mankind are also a key factor that causes fish number change to the destruction of Habitat for Fish, as spring or summer, at this moment fish for often busy season at this moment not well constraint of the administrative authority such as government in addition, cause the overfishing of a lot of lakes, fish quantity is reduced.
Therefore investigating large-size lake Mesichthyes community structure characteristics and the correlativity with water quality, inquire into the impact of mankind's daily life on lake biology and water quality, is that Ecology is learned the indispensable task of researcher.
Get back to behind laboratory having gathered fish sample, classification, measurement total length, height, body weight, dissection, collection flap, collection bulkage and preservation etc., be the work that more complicated is loaded down with trivial details, and it is many to gather the sample of returning, needs many people to coordinate.Therefore, simplifying laboratory measurement work is in our whole Ecological Investigation, to compare difficult task.
Utility model content
For addressing the above problem, the utility model provides a kind of pick-up unit device that can simultaneously measure fish body total length, height, body weight, can simplify the collecting work of laboratory fish sample body parameter, raises the efficiency.
A body parameter measurement mechanism for fish, described device can carry the weight of fish, and this device comprises base plate and first and second and three locating parts,
Described base plate has a measurement plane, on described measurement plane mark the first gage;
Described the first locating part is arranged on described base plate regularly, the first described locating part have above and perpendicular to the first described measurement plane, parallel with the first gage confined planes;
Described the second locating part is arranged on base plate or arranges on the first locating part, described the second locating part have above and perpendicular to the second described measurement plane, vertical with the first gage confined planes;
Described the 3rd locating part is slidably arranged on described measurement plane mutually, described the 3rd locating part have above and perpendicular to the 3rd described measurement plane, vertical with the first gage confined planes;
Described measurement plane subscript is provided with second gage vertical with the first gage, or described the second locating part or the 3rd locating part subscript are provided with vertical with the first gage and are parallel to the second gage of described measurement plane.
Preferably, the first described confined planes is provided with the slide rail for described the 3rd locating part relative sliding.
Preferably, the second described locating part is fixedly installed on base plate, or arranges slidably mutually with described the first locating part.
The body parameter measurement mechanism of fish of the present utility model, can disposable measurement fish body total length, height, body weight, can simplify the collecting work of laboratory fish sample body parameter, raises the efficiency.
Accompanying drawing explanation
Fig. 1 is the stereographic map of the body parameter measurement mechanism of fish of the present utility model.
Embodiment
Ginseng Fig. 1, the body parameter measurement mechanism of a kind of fish, this device comprises base plate 1, the first locating part 2(fixed dam), the second locating part 3(limiting stand), the 3rd locating part 4(moving stop);
The first locating part 2 is arranged on base plate 1 regularly, the first locating part 2 have above and perpendicular to the first measurement plane 11, parallel with the first gage 12 confined planes 21;
The second locating part 3 is arranged on base plate 1 or arranges on the first locating part 2, the second locating part 3 have above and perpendicular to the second measurement plane 11, vertical with the first gage 12 confined planes 31;
The 3rd locating part 4 and the first locating part 2 arrange mutually slidably, the 3rd locating part 4 have above and perpendicular to the 3rd measurement plane 11, vertical with the first gage 12 confined planes 41;
The second locating part 3 subscripts are provided with vertical with the first gage 12 and are parallel to the second gage 32 of measurement plane 11.
In this embodiment, the second locating part 3 is for being fixedly installed on for example, the limiting stand a little more than (2cm) measurement plane 11 on base plate 1.
The first confined planes 21 of the first locating part 2 is provided with the slide rail 21 for the 3rd locating part 4 relative slidings.
Specifically, in the time measuring, the head of fish and the first confined planes 21 are offseted, a flank portion and the second confined planes 31 of fish offset, and the opposite side belly of fish and the 3rd confined planes 41 offset; The first gage 11 is for measuring the height of fish, and the second gage is for measuring the total length of fish;
Whole device is placed on balance, can measures the body weight of fish.
In sum, the innovation practicality that the utility model real tool in like product is splendid is looked through domestic and international correlation technique data or patent documentation simultaneously, does not also find that same configuration discloses formerly.But the above is only the utility model part possible embodiments, the equivalent structure that all act application the utility model instructionss and claim are done changes, and ought to be included in the scope of the claims of the present utility model.
