What is the difference between farmed fish and wild fish, and what is the difference between wild so

1. Because the farmed fish are artificially farmed, there is more fat in the body, and they generally grow fatter and heavier; Wild fish, on the other hand, are wild and self-reliant, so they generally have little fat and grow thinner. The meat of farmed fish is relatively tender, but it is not as firm as the meat of wild fish, so wild fish taste more delicious and have a much better taste.

2. Because it is artificially cultivated, there is more bile in the body of the farmed fish, and the color is relatively dark, and the smell is relatively strong; Wild fish, on the other hand, have less bile, are lighter in color, and have a lighter fishy smell. Most of the excrement of farmed fish is black and has a particularly strong taste; Most of the wild fish are light in color, and the smell is much lighter than that of farmed fish. Generally, only by killing the fish, you can tell whether it is farmed fish or wild fish.

3. Because there are a lot of farmed fish now, artificially cultivated, there are few wild fish now, and most of the fish are farmed fish. Wild fish are much more viable than farmed fish and do not need artificial oxygen, while farmed fish are the opposite. Because wild fish are wild, they tend to vary in size, but farmed fish are all farmed, so they are all about the same size, and the fish are almost all the same species in batches.

Difference Between Wild Fish and Farmed Fish.

There is a big difference between wild fish and farmed fish, and this internal difference includes not only taste, but also the characteristics of internal organs

1. Due to the abundant feed and rich nutrition, farmed fish are generally fat and strong, while wild fish are often emaciated and slender due to full competition in the natural environment.

2. The fat content of artificially raised fish is very high, not only the abdominal cavity and fish intestines are full of fat, but even the fish skin may be a thick layer of fat, and even the fish belly is mainly fat. However, due to the lack of food, wild fish tend to have very low body fat content, less fat in the intestines and abdominal cavity, and less fat on the meat of wild fish.

3. Due to the high fat of the feed, the farmed fish will lead to high cholesterol, and the gallbladder of the farmed fish is large, with a lot of bile and a strong color. Wild fish have smaller gallbladders and less bile, and are lighter in color.

4. Due to the consumption of high-fat and high-protein feed made by artificial mixture, and the amount of food is large, regular feeding, and the digestion and absorption rate is low, therefore, the excrement of farmed fish is often black, and the fishy smell is very strong. However, due to the consumption of pure natural food, and the amount of food is small, the digestion is very sufficient, and the wild fish defecation is light in color and has a much lighter fishy smell. If you look closely at the water quality in the fish pond, you can see it.

5. The peritoneum is also the basis for distinguishing wild fish from farmed fish. Due to the feed and living environment, farmed fish often have a very dark black membrane in their belly, while wild fish have no black membrane or a very shallow black membrane.

6. Wild fish are caught, often with many varieties and different sizes, while farmed fish are often fished in batches, and there is little difference in size.

Look at the size of the fish.

Wild crucian carp tend to be relatively small, short and lean, while domestic crucian carp are generally larger and tame because of their abundant food resources.

2.Look at the color of the fish.

After looking at the size of the crucian carp, the color of the crucian carp is also something we must observe, and the wild crucian carp is whitish in color and tends to be yellow. Whereas, the color of the domestic crucian carp is black, and if it is purely artificially raised, then the color is dark black.

3.Look at the size of the fish.

In addition to the above two points, the size of the crucian carp is also very important. Wild crucian carp have a slender body, a rounder head, a ferocious swimmer, and a wider tail, while domestic crucian carp do not have these characteristics.

4.Look at the back of the fish.

In the wild, crucian carp have a high back and a prominent protrusion. The captive-bred crucian carp has a large and flabby belly because it is well eaten, and the back bulge is not obvious.

5.Look at the gill color.

In order to make the fish grow up, some drugs and even hormones must be put on a regular basis, and these drugs or hormones will be reflected in the gills, compared with wild crucian carp, the gills of farmed crucian carp are darker in color and dull in luster.

The difference between wild fish and farmed fish is the difference in body shape, body color, and fat content.

1. Body shape differences

There is a big difference between wild fish and farmed fish in body shape, because wild fish live in the wild and need to hunt by themselves, and their survival pressure is greater, so the body shape of wild fish is slender and small, and the farmed fish is relatively fat and strong due to the regular feeding of feed.

2. Different body colors

Most of the wild fish grow in flowing waters, and the water quality is relatively clear, so the color of its body surface is relatively light, and the scales are thin and shiny, while the farmed fish live in still water and have a certain amount of silt at the bottom, so its body surface is dark in color and the scales are thick.

3. Fat content

The survival pressure of wild fish is high, and each predation may not be full, so its fat content is low, especially the abdominal part is more obvious, in addition, the excrement of wild fish is less fishy, and the feed nutrients fed by farmed fish are sufficient, so the fat content is higher, and the excrement has a strong fishy odor.

Principles of fish selection:

1. Look at the fish's eyes

Looking at the eyes of the fish, you can judge whether the fish is fresh or not most directly. The fresher the fish, the more bright and transparent the eye area should be, and the eyeballs should be prominent. If the color of the fish's eye looks cloudy and the eyeball is sunken, then it proves that the freshness is not enough, so buy with caution.

2. Look at the gills

The gills of a fish refer to the gills of a fish. We all know that the gills of fresh live fish are very tight, and when you open the gills, you can see that the gills inside are bright red. On the other hand, if the gills of the fish can be easily opened, and the color appears dull and rotten, then it proves that the fish is not fresh enough and is not recommended to buy.

The differences between wild fish and farmed fish are as follows:

The size and size of the fish are different: wild fish are always emaciated and small due to the relatively large competition in the living environment, and the fish body is short and strong. The farmed fish are abundant in dry feed and rich in nutrition, so they are generally fat and strong-eyed and docile.

Different body surface colors: Wild fish are light in color, with thin scales, grayish-white, bright luster, slender and narrow, with inconspicuous back and belly lateral lines, and uneven body color. The farmed fish live in still water with a certain amount of silt deposits, and the color is dark and black, and the scales are on the building side.

The fat content of the body is different: wild fish are expensive by dry food, often the body fat content is very low, the fat in the intestine and abdominal cavity is relatively small, the fat on the fish meat is less, and the fat content of farmed fish is high because the feed is high fat.

Wild fish farming methods

Trapping water in advance: If you want to raise fish, you must prepare water in advance, and the general tap water cannot be used directly to raise fish, because the water contains residual chlorine, although the content is not high, but it will also be harmful to the health of the fish. Usually, the water should be connected and put in a sunny place to dry for one to two days, so that the chlorine gas can volatilize, so as to ensure the survival of blind fish in the water body.

Rest and wait: After putting the wild fish in the water, you need to rest for a period of time, because the environment changes, the fish may have a stress response, and will not eat during the period, you can not feed it at this time, and do not change the water, try to avoid disturbing it, usually it takes three days to rest, so that it can adapt to the new environment.
