Method for identifying pampus argenteus, pampus punctatissimus and pampus chinensis

Abstract

The invention relates to a method for identifying pampus argenteus, pampus punctatissimus and pampus chinensis, which comprises the following steps of: measuring five appearance indexes of pomfret species to be identified, namely head length, body length, body height, the length of caudal peduncle and the height of caudal peduncle; and after performing conversion, substituting into a comprehensive identification formula to distinguish the pampus argenteus, the pampus punctatissimus and the pampus chinensis quickly, and the accuracy rate of identification is 100 percent. Compared with the conventional identification method, the method is easy to operate and can be easily mastered by fish taxonomy nonprofessionals.

Description

technical field [0001] The invention belongs to the technical field of fish identification, in particular to a method for identifying silver pomfret, pomfret and Chinese pomfret. Background technique [0002] Pomfrets are widely distributed in the Yellow Sea, the East China Sea and the South my country Sea, and occupy an important position in my country's offshore fisheries. Especially in the past 20 to 30 years, with the successive depletion of large and small yellow croaker and hairtail resources in my country's four major fisheries, pomfret has been paid more and more attention by domestic and foreign experts and fishery management departments. Silver pomfret, pomfret and Chinese pomfret are common species in the genus Pomfret, and they are the main fishing objects of pomfret in my country. However, the appearance of these three pomfrets is extremely similar, and their classification and identification methods have always puzzled fish taxonomists. Until 2002, Liu Jing a...

AI Technical Summary

Problems solved by technology

[0003] At present, although silver pomfret, plume pomfret and Chinese pomfret can be identified according to the classification and identification standards and methods of scholars such as Liu Jing, the operation is relatively cumbersome and requires strong professional knowledge, which is not conducive to the fishery management department's identification of silver pomfret and plume pomfret. For rapid classification, identification and statistical management of pomfret catches and Chinese pomfret catches, a simple and quick classification and identification method that does not require a lot of professional knowledge is needed
