The methods to distinguish wild yellow-winged fish from culture:

1. Fish mouth. Wild fish need to peck in the sea, and the shape of fish mouth is sharp. However, feed culture will swallow feed in one gulp, so a round mouth is conducive to fish eating.

2. Fin. The pectoral fins and ventral fins are yellow, and the cultured fins are pink.

3. Fish belly. Bright, the shark's fin is red, and the wild yellow-winged fish is sensitive to the requirements of temperature and water quality when it goes ashore, and the shark's fin will be red after a while; The lower abdomen of farmed fish is pink.

4. Fish body. Wild fish are white and slender; Cultured fish are darker and rounder.

5, fishtail. Compared with aquaculture, wild yellow-winged fish is slender. This is because living in the natural environment, experiencing tidal changes, different sea areas, fish's activity ability is also different, slender helps to swim faster. The cultured yellow-winged fish is limited by the cage, and its activity area is small, so it is narrow and round because it is not affected by the tide.
