How to identify the quality of fish species

First, to see whether the specifications are uniform of the same kind of fish, those who come out of the pond with uniform specifications are generally more physically fit. Second, to see if the fish is glossy and strong, there is a layer of mucus on the body surface of the fish to protect the scales and skin from germs, so the body surface shows a certain luster. On the other hand, the body surface of sick and injured fish is lack of mucus and no luster, or some diseased fish have too much mucus and lose their luster. Third, the body color of the fish species reflects its advantages and disadvantages through the body color of the fish species. The body surfaces of high-quality fish species are respectively:

The body surface of herring is bluish gray and white, and the lighter the color of the fish, the stronger the physique.

Grass carp body light golden yellow, gray-black reticulation, obvious scales, the stronger the fish body, the more obvious light golden yellow.

The body color of blunt snout snout bream is dark gray, and the stronger the fish is, the more gray the surface color is.

Silver carp back silver gray, both sides and abdomen silver white.

The body surface of bighead carp is light golden yellow, and the black markings are not obvious. The stronger the fish is, the less obvious the black net pattern is, and the more obvious the golden yellow is.

Carp due to different species, its body color is different, generally have cyan, red or golden yellow, no matter what kind of body color, bright gold, the more obvious the stronger the fish. Fourth, look at the swimming situation of the fish species. Strong fish species swim lively. Fifth, sampling inspection selects the fish of the same specification to weigh 0.5 kg, calculate the Mantissa, and then check the specification identification table of high-quality fish. If the Mantissa of 0.5 kg of fish in this specification is less than the standard, it is a high-quality fish species.
