How to tell if crucian carp is wild? Do wild crucian carp and domestic crucian carp have the same nutritional value?

Crucian carp is a kind of fish that we often eat in daily life. There are two types of crucian carp: farmed and wild. Although they are both fish meat, they are different in the way they are raised. So are there any nutritional differences between the wild and domesticated crucian carp?

How to tell if crucian carp is wild

Look at the fish scales

The scales of wild crucian carp are golden or silvery yellow and shiny. The scales of farmed crucian carp are dark and darker in color, and their bodies are often damaged. This difference is related to the growth environment of crucian carp.

Look at the head

Wild crucian carp need to find their own food, eat less, and grow slowly, so they are slender and small, usually only 3-8 taels. Because wild crucian carp are constantly swimming, the fins on their backs are more developed, the tail is also wider, and the back looks convex. Farmed crucian carp are generally larger in size because they have abundant fish food, especially the belly is larger, the body is slightly wider, and the convexity of the back is not obvious.

Look at the color of the fish gills

The growth environment of wild crucian carp is basically running water, so the gills are relatively clean. The gills of farmed crucian carp will be attached to the silt and the color is darker, especially the fish intestines in the belly of the fish have more dirt.

Look at the meat quality

Wild crucian carps are active frequently, so their meat is firm and feels harder. Farmed crucian carps are less active, do not need to look for food, and eat artificially processed fish food, so their meat is relatively soft and does not have the dense feeling of wild ones.

Are wild crucian carp and domestic crucian carp nutritionally equivalent?

There is no nutritional difference between wild crucian carp and domestic crucian carp, but their feeding methods are a little different, so the taste and texture of the meat are a little different. But the nutritional effect is the same.

Crucian carp bred in the weir ponds are basically fed with feed, so some people worry that some hormones in their bodies will remain in their bodies and be harmful to their bodies. In fact, there is no need to worry about this, because these feeds must also be inspected by relevant institutions.

What bait to use for fishing wild crucian carp

1. Earthworm bait.

It is mainly used in late spring and autumn, and is also the most commonly used bait!

2. Red worm bait.

Red worm bait is high in protein and fat, and is best used in winter and spring. It has a strong fishy smell, high nutrition, and stimulates fish to bite. It is not used in other seasons because it will attract small fish and make fishing impossible.

3. Sticky rice.

In the summer when there are a lot of small fish, red worms and earthworms are no longer useful, and you don’t want to use bait, so you use "red worms with empty hooks" and sticky rice wine to fish. The effect is very good, and most of the big crucian carp are caught. Of course, medium-sized carp and grass carp are also common.

4.Commercial bait.

We mostly use long poles and short lines for wild fishing here, so there are relatively few people who use pull bait. The key is that we are not used to it. If the bait fails to open, it will be difficult to catch fish. In recent years, more and more anglers have been involved in platform fishing, and more and more people are using commercial bait.
