Embodiment

[0016] Example: With reference to Figures 1 to 4, a terminal device for identifying male and female squids includes a terminal body with a camera and a screen, wherein: the terminal has the ability to take photos of the male squid whose sex is to be identified and The program to calculate the position of the wrist, foot or the end of the wrist contact from the photo; manually select the left 3 wrist end, the left 4 wrist end, the left wrist contact end, and the tail end, and measure the distance between the above end and the measurement baseline The program calculates the left 3 wrist length, left 4 wrist length, left touch wrist length, and carcass length, and uses the following expression to calculate:

[0017] Male: F1= 223.42 X 3 + 165.85 X 4 + 7.951 X 5 -108.06;

[0018] Female: F2= 151.48 X 3 + 92.71 X 4 + 19.19 X 5 -60.38;

[0019] In the above discriminant, the X 3 Replace the left 3 wrist length / carcass length, X 4 Replace with left 4 wrist length / carcass length, X 5 Su...

Abstract

The invention discloses terminal equipment for discriminating male and female sepiella maindroni. The terminal equipment comprises a terminal body, wherein the terminal body is provided with a camera and a screen; the terminal is provided with a program for taking a picture of the sepiella maindroni to be discriminated, and calculating the peduncle or tentacula end positions from the picture; by artificially selecting the left peduncle 3 end, the left peduncle 4 end, the left tentacula end and the tail end in a point way, and measuring the distance differences between the measuring base line and the left peduncle 3 end, the left peduncle 4 end, the left tentacula end and the tail end, the program can calculate the lengths of the left peduncle 3, the left peduncle 4, the left tentacula and mantle length; by adopting a discriminant to calculate, the type is judged according to the maximum values obtained by F1 and F2, wherein F1 represents male, and F2 represents female. The terminal equipment has the advantages that by utilizing the discriminant, the discriminating accuracy is high, the discriminating is visual and fast, the operation is easy and simple, and the injury to to-be-distinguished organisms is avoided, the result is accurate, the operation is simple, and the injury to organisms is avoided.

Description

Technical field [0001] The invention relates to a marine organism gender identification device, in particular to a terminal device for judging male and female squid. Background technique [0002] Man's needle-free squid ( Sepiella japonica ) Belongs to the phylum Mollusca, Cephalopod, Squididae, and Needleless Sepia. It is one of the important marine fishery economic species in China. It was once one of the "Four Marine Products" in the East my country Sea. The highest annual output in history is only Zhejiang More than 60,000 tons (Dong Zhengzhi, 1988). However, since the end of the 1970s, due to overfishing and the destruction of water conditions, its resources have declined severely; in the middle and late 1980s, the needle-free squid in Zhejiang coastal fishing grounds has been unable to form a fishing flood (Wu Changwen et al., 2010). Scholars at home and abroad mainly focus on resource status (Tang Yimin et al., 1986), biology (Jiang Xiamin et al., 2007; Chang Kangmei et al...
