Embodiment Construction
[0028] The present invention will be further described below in conjunction with embodiment.
[0029] A method for quickly distinguishing different molting periods of river crabs. The principle is based on the tightness of the inner epidermis of the carapace and the exoskeleton at different molting periods, thus presenting different color differences, and using a colorimeter to read the color values at different molting periods , so as to distinguish and divide the moulting cycle stage of the individual. According to the color difference of the carapace in different molting periods of river crabs, the present invention establishes the color value ranges of river crabs in different molting periods, uses a colorimeter to read the color data of individuals in different molting periods, compares the color values, and determines and divides the molting cycle stages of individuals. It is convenient, quick, easy to operate, and has high accuracy, which is of great significance to...
