1, fish scale, fish fin, fish tail color
The colors of scales, fins and tails of wild carp, whether yellow or red, are very bright, while those of carp raised in cages, reservoirs or ponds are relatively dark. From a distance, there may be little difference, but from a closer look, there is a big difference.
2. Body shape and figure
The slender figure of wild carp has a lot to do with their long-term exercise and eating habits. Wild carp need to find their own food, often full and hungry. Moreover, raising carp does not worry about eating and wearing. Open your mouth and clothes and open your hands every day, and you are too lazy to exercise. I slowly grow into a bucket waist, a fat body.
3. Color of gills
The gills of wild carp are bright red, even in places with poor water quality. But the gills of carp are very dark, without any luster, and some are even dark.
4, feel
When buying fish, you can touch the scales with your hands. The scales of wild carp are very delicate and smooth to the touch, and the scales of raised carp are also very rough.
5. Meat quality and taste
The flesh of wild carp is delicate and firm, while the flesh of raised carp is rough and loose, and it feels completely different when eaten in the mouth.
