This standard replaces GB/T 21441-2008 "Gum", compared with GB/T 21441-2008, the main changes are as follows.
--- Complementing the 3.2 countable traits and the 3.3 quantifiable traits in GB/T 21441-2008 (see 4.2 and 4.3);
--- In GB/T 21441-2008 4.1, the regression equation for the relationship between body length and weight has been added (see 5.1);
--- Deleted Chapter 6 of the GB/T 21441-2008 biochemical genetic characteristics and the corresponding detection methods;
--- Increased COI gene sequence fragment as a molecular genetic feature (see Chapter 7);
--- Chromosomal detection method refers to the method of GB/T 18654.12 (see 8.4);
--- Supplements the detection methods for external morphological characteristics, growth and reproduction characteristics, and molecular biological characteristics (see 8.2, 8.3, 8.5).

The body is oval in shape, flattened, with both eyes on the left side of the head; with small scales on the side of the eye, brown, yellowish brown or gray-yellow, usually with three
Dark black spots, no white eye with round scales. The left and right sidelines are equally well developed and there are no upper branches. Tail shank is long and tall. There are two nostrils on the side of the eye
About in front of the middle of the eye septum, there is a narrow flap at the posterior edge of the anterior nares; no ocular side two nostrils are close to the dorsal edge of the head, and the anterior nasal orifice is also narrow
Long flaps. The mouth is large, the anterior position, and the jaw is slightly prominent; the mouth is oblique and symmetrical. The dorsal fin begins approximately at the anterior edge of the upper eye, the left and right pelvic fins are slightly symmetrical, and the posterior edge
Double truncated; odd fins have dark stripes, pectoral fins with dark spots or horizontal stripes. Sharp teeth, cone-shaped, up and down each line, are equally developed; anterior teeth
The teeth are large and canine teeth.
