The invention is brand new, and can realize the measurement of fish body shape data through two vertical and horizontal scales. In the implementation of the case, the carp carp is selected as the measurement object, and the data to be measured is the horizontal data of the fish, including head length, full length, and longitudinal data body height and tail peduncle height.

First, the slider 710 on the longitudinal scale 700 is installed on the slideway 610, and then the measurement panel 100 is fixed on the frame-shaped interlayer support body 300 to form the measurement board of the present invention.

During measurement, the sliding handle 720 is inserted through the chute 140 and screwed on the longitudinal scale 700 . Then fold the detachable baffle into a 90° right angle, insert it into the 90° right angle slot 110 of the measurement panel 100 , and tighten the set screw 400 to fix the detachable baffle 500 on the measurement board. Place the vertical scale 700 at the 0 scale of the horizontal scales 120 , 130 . Take out the crucian carp to be tested and place it in the center of the measurement panel 100 as far as possible, and stick the snout on the baffle plate 510 .

First measure the horizontal axis data:

1. Head length: Slide the horizontal measurement scale reading mark scale line 730 of the longitudinal scale 700 to the rear edge of the gill cover of crucian carp, and the horizontal measurement scale line 121 or 131 of the horizontal scale 120 or 130 corresponds to the horizontal measurement scale reading mark scale line 730 The position reads the reading on the horizontal measurement scale line 121 or 131, and this reading is the head length.

2. Full length: Slide the horizontal measurement scale reading mark scale line 730 of the longitudinal scale 700 to the end of the caudal fin, and read at the position where the horizontal measurement scale line 121 or 131 of the horizontal scale 120 or 130 corresponds to the horizontal measurement scale reading mark scale line 730 The reading on the scale line 121 or 131 is measured horizontally, and this reading is the full length.

Then measure the vertical axis data:

1. Body height: slide the horizontal measurement scale reading mark scale line 730 of the longitudinal scale 700 to the highest bulge on the back of the fish body, read the superscript scale and the subscript scale on the longitudinal measurement scale line 740 of the longitudinal scale 700 respectively, and place the upper Add the subscript scale and the subscript scale to get the actual body height of the fish

2. Tail shank height: Slide the horizontal measurement scale reading mark scale line 730 of the longitudinal scale 700 to the minimum height of the fishtail handle, read the superscript scale and the subscript scale on the longitudinal measurement scale line 740 of the longitudinal scale 700, and place Add the superscript scale and the subscript scale to get the actual tail peduncle height of the fish.

After use, loosen the set screw 400 to remove the detachable baffle, and then fold the baffle 510 and 520 for easy portability. It can be seen from the embodiment that the fish measuring device does not need to turn the fish body during use, but only needs to move the sliding handle 720 to conveniently and accurately measure a plurality of fish body shape data. The horizontal measurement scale reading mark scale line 730 on the vertical scale 700 can make the horizontal measurement scale line 121 or 131 reading of the horizontal scale 120 or 130 more accurate, and two horizontal scales 120, 130 are set on the measurement panel 100, which also eliminates the need for Turn over the hassle and error of fish readings. Furthermore, the slidability of the vertical scale 700 and the design of placing the 0 scale in the center also solve the problem of difficult data measurement in the vertical direction, and the measurement process is also convenient and accurate. The detachable and folding of the measuring device baffle also makes the measuring device have certain portability.
