1, different sizes

The growth rate of wild crucian carp is very slow, and it only takes about three years to grow from fry to150g. The price of wild crucian carp in the market is very expensive, and they are all relatively small, not exceeding one catty. The engineering crucian carp grows fast, and it can grow to 1000 grams in a year, so the larger crucian carp are not wild crucian carp. Remember that the smaller crucian carp is better than the bigger one.

2. Different body types

Engineering crucian carp, which grew up eating feed, generally has a raised back and a wider body. The wild crucian carp is spindle-shaped, with a smaller head and a narrower body, which is caused by lack of food.

3. Different lateral scales

The lateral line of wild crucian carp has only 28 lateral line points, and the number of scales from the lateral line is only 28. The lateral line scales of engineering crucian carp is generally 30 ~ 32 pieces, with 2~4 pieces more, which is a key difference. Even if small engineering crucian carp is used to impersonate wild crucian carp, the size can be impersonated, but lateral line scales cannot impersonate it.

Wild crucian carp, also known as native crucian carp, lives in natural waters, but naturally propagated crucian carp in reservoirs, rivers and ponds are not fed with feed. Engineering crucian carp, also known as Xiangyun crucian carp, is a new triploid fish bred by bioengineering technology and grew up eating feed. The growth rate of engineering crucian carp is very fast, three times faster than that of common crucian carp, and the meat yield is high, but the meat is loose and not delicious.
