Embodiment 1

[0017] The statistics of embodiment 1 red-eyed trout scale formula

[0018] (1) Put the fresh red-eyed trout collected in the wild on the blue background plate, keep the side of the body upward and fully stretched. Use a mobile phone or camera to take a full-body profile photo of the red-eyed trout in a static state to ensure that the lateral line scales, lateral line scales, and lateral line lower scales in the image are clear and complete.

[0019] (2) Use PS software to process the profile photo of the red-eyed trout, according to figure 1 The method shown in the picture in the middle divides the lateral line scales of the red-eyed trout into three segments: front, middle and back.

[0020] (3) Use the ruler tool in the PS software to measure the length of the lateral line scales of the three segments of the red-eyed trout, in which the length of the lateral line scales of the front segment of the red-eyed trout is L A-B =35.87, mid-section L B-C =27.76, rear section L ...

Abstract

The invention relates to a method for quickly counting fish scale forms. The method includes the following steps: (1) keeping the side face of a fish body upward, shooting the whole body of the side face of the fish, and ensuring that lateral line scales, lateral line upper scales and lateral line lower scales of the fish are clear and complete; (2) using image processing software to divide the fish lateral line scales into a front section, a middle section and a rear section, measuring the lengths of the three sections of lateral line scales, and respectively measuring the lengths of the upper lateral line scales and the lower lateral line scales of the fish in the same way; (3) respectively selecting single scales from the front section, the middle section and the rear section of the lateral line scales, the lateral line upper scales and the lateral line lower scales of the fish body, and measuring the lengths of the exposed scales; and (4) finally, calculating and obtaining a lateral line upper scale number and a lateral line lower scale number. The method does not need to count the scales one by one, is quicker, avoids subjective errors, is more accurate in counting result, and can also avoid the situation that the scales are small or fall off and cannot count.

Description

technical field [0001] The invention relates to a method for rapidly counting fish scale patterns, which belongs to the field of fish countable property measurement and statistics. Background technique [0002] In the field of fish ecology research, fish scales can not only identify the age of fish and reflect the growth characteristics of fish, but also can be used to analyze the fish scale type (including the number of scales on the lateral line, the number of scales on the lateral line and the number of scales below the lateral line). Therefore, it has become a basic and routine operation to make statistics on fish scales during the investigation of fish resources. At present, the fish scale statistical method commonly used in fish resources investigation is mainly to directly observe and count the lateral line scales, lateral line scales and lateral line underside scales with the naked eye. Live fish are easy to swing and have a large number of scales. Direct observatio...
