Problems solved by technology

At present, the traditional fish measuring board is used for measurement, but the existing fish measuring board only has a horizontal scale, and often cannot be completed independently when measuring the overall length, body length, fork length, body height, and tail peduncle height of the fish body, and requires the help of Auxiliary tools are used to complete the measurement; and random errors are added while turning the fish body, resulting in the unreliability of the same batch of fish measurement data and the increase of the relative error between batch measurements
In addition, due to the characteristics of irregular shape, relatively large space occupation, and not easy to carry, the fish measuring board increases the workload and difficulty of researchers when conducting field investigations.

Embodiment Construction

[0023] In order to make the technical means, creative features, goals and effects of the present invention easy to understand, the following examples will be used to further illustrate the present invention, but the embodiments of the present invention are not limited thereto.

[0024] see Figure 1 to Figure 4 , the fish measuring device shown in the figure comprises a measuring board, the measuring board is made of a measuring panel 100 made of plexiglass and a base plate 200 supported by plexiglass, and the measuring panel 100 is fixed on the base plate by a sandwich support body 300 200, a sandwich space is formed between the lower surface of the entire measurement panel 100 and the upper surface of the bottom plate 200, so as to facilitate the installation of the longitudinal scale and slideway described later. The interlayer support body 300 forms a frame shape.

[0025] A 90° right-angled draw-in slot 110 is provided at the zero-scale end of the measuring panel 100 clo...

Abstract

The invention discloses a fish body measurer, comprising a measuring plate, and a longitudinal ruler, wherein at least one transverse ruler extending along the length direction of the measuring plate is arranged on the measuring surface of the measuring plate; transverse measurement graduation lines are arranged on the transverse ruler; the longitudinal ruler is arranged on the measuring surface of the measuring plate in a sliding way and can slide along the length direction of the measuring plate, wherein the longitudinal ruler is vertical to the transverse ruler; and longitudinal measurement graduation lines are arranged on the longitudinal ruler. The fish body measurer is made of organic plastic; the transparent visual ruler graduation has the characteristics of large contrast and easiness in reading so that the measurement operation can be effectively done; and simultaneously, the combined design of dual-interlayer and chute leads the fish body measurer to be simple and light.

Description

technical field [0001] The invention relates to the technical field of biological measurement, in particular to a fish body measuring device suitable for measurable properties of fish. Background technique [0002] In ichthyological research, the measurable trait indicators of fish mainly include total length, body length, fork length, body height, tail peduncle height, etc. These biological morphological indicators are necessary basic data for ichthyological research, and ichthyological research A large number of field investigations are often required, so it is necessary to carry professional measurement tools for measuring these biologically measurable traits of fish. At present, traditional fish measuring boards are used for measurement, but the existing fish measuring boards only have a horizontal scale, and often cannot be completed independently when measuring the overall length, body length, fork length, body height, and tail peduncle height of the fish body, and nee...
