Embodiment

[0016] Example: refer to Figure 1 to Figure 4 , a terminal device for judging the male and female squid, including a terminal body with a camera and a screen, wherein: the terminal can take photos of the squid to be identified and calculate the arms, feet or tentacles from the photos The program of the end position; by artificially selecting the end of the left 3rd wrist, the end of the 4th wrist, the end of the left touch wrist, and the end of the tail, and by measuring the distance difference between the above-mentioned ends and the measurement baseline, the program calculates the left 3 wrist length, left 4 wrist length, left touch wrist length, trunk length, and use 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 Replaced by left 3 wrist length / body length, X 4 Replaced by left 4 wrist length / body le...

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 device for identifying the sex of marine organisms, in particular to a terminal device for identifying male and female squid. Background technique [0002] Man's Needleless Squid ( Sepiella japonica ) belongs to the phylum Mollusca, Cephalopoda, Sepiaceae, and Sepia genus. It is one of the important economic species of marine fishery in my country. It was once one of the "four seafoods" in the East my country Sea. The highest annual output in history is only in 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 seriously; in the mid-to-late 1980s, the squid in the coastal fishing grounds of Zhejiang could not form a fishing season (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...
