[0024] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor belong to the scope of protection of the utility model.

[0025] The utility model discloses a kind of brine shrimp length measuring tools, to solve the problems of related technologies, the length of brine shrimp sample can be measured in batches, improve measurement efficiency and measurement accuracy.

[0026] In order to make the above purposes, features and advantages of the utility model more apparent and easy to understand, the utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0027] As Figs. 1-3 Indicated, the embodiment provides a kind of brine shrimp length measuring tools, including measuring disc 1, measuring disc 1 is provided with multiple measuring grooves 2, each measuring groove 2 can accommodate single tail brine shrimp sample, and each measuring groove 2 is provided with length scale layer 3 in its length direction, to measure the length of corresponding brine shrimp sample.

[0028] In the embodiment, measuring disc 1 is rectangular plate, and the material of measuring disc 1 is preferably transparent, light-transmitting plastic material.

[0029] Further, the length of measuring disc 1 is 280mm-300mm, the width is 180mm-200mm, and the height is 7mm-10mm.

[0030] In the embodiment, measuring groove 2 is rectangular groove.

[0031] Further, the length of measuring groove 2 is 60mm, the width is 10mm, and the depth is 5mm.

[0032] In the embodiment, all measuring grooves 2 are arranged in rectangular array in the middle of measuring disc 1.

[0033] Further, the spacing of each row of adjacent measuring grooves 2 is 2mm; the spacing of each column of adjacent measuring grooves 2 is 2mm.

[0034] In the embodiment, numbering layer 4 is further provided in each measuring groove 2; specifically, Fig. 2It is explained that the measurement grooves 2 in the embodiment are provided with 30, and every 10 measurement grooves 2 is 1 column, and a total of 3 columns are arranged in the middle of the measuring disc 1. The left upper corner of each measurement groove 2 is provided with a corresponding numbered layer 4, so as to mark the 30 measurement grooves 2 as No. 1-30. The length scale layer 3 in each measurement groove 2 is provided with a scale value, which is mm.

[0035] In the embodiment, the length measurement tool of the prawn further comprises an image shooting mechanism, which is arranged near the measuring disc 1. The image shooting mechanism can take a photo of the measuring disc 1 to read the length of the prawn sample in each measurement groove 2.

[0036] Further, the image shooting mechanism is a stereomicroscope. It should be noted that the length of the prawn sample is usually very small (the body length of the prawn is less than 40 mm), and it is difficult to directly observe the classification characteristics with the naked eye. Therefore, the stereomicroscope can be used to magnify and observe the classification characteristics of the prawn sample on the measuring disc 1. At the same time, the built-in shooting system of the stereomicroscope is used to take a whole photo of the prawn sample on the measuring disc 1. Since the obtained photo is the result of the magnification of the stereomicroscope, it is not only convenient to read the length of the prawn sample, but also can take a photo containing the length of 30 prawn samples at one time, which is convenient for data backtracking. Those skilled in the art can also select a camera with magnification and shooting function as the image shooting mechanism according to the needs.

[0037] The use process of the prawn length measurement tool provided in the embodiment is as follows:

[0038] Step one, clean the measurement tool, make it clean and free of damage, mark the batch of measurement on the blank with a marker pen, and dry quickly or naturally.

[0039] Step two, select the prawn sample to be measured. The prawn sample should be fresh, complete and accurate in species identification.

[0040] Step three, put the selected prawn sample into the measurement groove 2 of the measurement tool one by one, not more than 30 at a time, and put the length measurement starting point of the prawn sample against the top end of the corresponding measurement groove 2.

[0041] Step four, observe the shape of the prawn sample in the measurement groove 2, and pay attention to the complete shape and neat arrangement.

[0042] Step five, place the measuring disc 1 on the stage of the stereomicroscope, and use the stereomicroscope to check the prawn classification characteristics (the measuring disc 1 can also be placed on the desktop, and a magnifying glass can be used to check the prawn classification characteristics). The shooting system of the stereomicroscope is used to take a photo of the measuring disc 1 (a camera can also be used for magnification and shooting).

[0043] Step six, clean the measuring disc 1. If there are still prawn samples to be measured, repeat steps one to six.

[0044] Step seven, after the work is completed, read the length of the 30 prawn samples through the photographed pictures, and at the same time, conduct secondary identification of the types of the prawn samples to ensure the accuracy of the type identification results.

[0045] In summary, the prawn length measuring tool provided in the embodiment solves the problems of low efficiency, easy errors and high time cost in the traditional use of a ruler to measure the length of prawn samples; the measuring tool uses a plurality of measuring grooves 2 arranged in a rectangular array on the measuring disc 1, an auxiliary length scale layer 3 and a numbering layer 4, and in combination with the use of an image shooting mechanism, the measuring tool realizes the measurement and photographing of 30 prawn samples at a time, effectively reduces the prawn measuring time consumption, improves the prawn length measuring efficiency, and has the advantages of retaining pictures, reducing experimental costs and the like.

[0046] The principle and implementation mode of the present application are described by using specific examples in the present application, and the above embodiment is only used to help understand the method and core idea of the present application; meanwhile, for the general technical personnel in the field, according to the idea of the present application, there will be changes in the specific implementation mode and application range. In summary, the content of the present application should not be understood as a limitation of the present application.
