What is the difference between river carp and farmed carp

The difference between wild carp and farmed carp.

The difference between wild fish, ecological fish and farmed fish is, to put it bluntly, the same as the difference between wild boar, native pig and farmed pig.

Wild Yellow River carp: growing in the Yellow River channel, wide range of activities, pure natural bait, miscellaneous, large activity, long growth cycle, about one and a half catties of fish growth cycle in 2 3 years or even longer, sexually mature and has laid eggs at least once. It is light in color, with golden scales and a red tail, and its body is slender and long.

The meat is porcelain, and the soup is delicious, and it is also suitable for making various dishes.

Semi-wild Yellow River carp: artificial seedlings, growing in the Yellow River channel, large activity, pure natural bait, miscellaneous food, large activity, long growth cycle, about one and a half pounds of fish growth cycle to 2 3 years, sexually mature and have laid eggs at least once. It is light in color, with golden scales and a red tail, and its body is slender and long.

The meat is porcelain, and the soup is delicious, and it is also suitable for making various dishes.

Ecological Yellow River carp: artificial seedlings, grown in ponds, fed with artificial ecological feed, and stopped eating for more than 2 months before sales. 2 3 years to about 2 3 pounds. It is medium in size, and it is slightly inferior in soup, and can be used to make various dishes such as steamed carp.

The Yellow River carp cultured in general ponds: artificial seedlings, grown in ponds, fed with compound feed, and can grow to about 2 catties in a year. It must be marketed before sexual maturity, otherwise the cost of carp will increase if the seeds are shaken and then fattened.

It is not suitable for soup and steaming, but is suitable for sweet and sour, braised food, barbecue, spicy and other delicacies with a strong taste.

The Yellow River carp is a chameleon, and the color of the carp varies greatly from different soil quality to the environment, and the color of the carp in different ponds in the Yellow River beach area varies greatly. Even the Yellow River carp raised in the pond will become golden scales and red tails as long as they are placed in the Yellow River for a few days, which is what we often call soaking fish, and wild fish will become dark and black in color after a few days in clear water. The way to distinguish between wild and pond culture is to look at the body type, wild fish are thin and long, the section is flat and round, and the pond is fat and the section is wide.

Wild fish are strong and clever, and they are not easy to catch; Pond fish are clumsy and easy to catch.

From the color, it can be distinguished, the color of the river carp is yellow, the culture is black, the meat quality of the river carp is tough, and the surface of the culture.

Wild carp have catch scars, and they are smaller, and the meat is delicious and rarely smelly.

The scales of artificially farmed carp are relatively intact, neat, and relatively black, and the basic market sells all of them.

Basically, the whole of the farming looks more like a wild one.

My grandfather was a former fisherman in Taihu Lake, and he could eat wild carp every year when he went back, and the state banned fishing at some point. I don't like fish, but wild carp really doesn't smell fishy and I can eat it.

There are three main differences between river carp and carp, in terms of body size: river carp is relatively slender and long, carp is fat and has a large belly. Appearance:

The lip of the river carp is rubbed by sediment during foraging, and the lower lip is relatively thicker, and the scales are yellow and shiny, and there are many scratches. The scales of carp are thick and blackish-gray in color. On the palate:

The flesh of the carp is fine, and the carp is soft and soft.

Lili should start eating early. The feeding adheres to the principle of "four determinations", and the earlier the opening of the fry is opened, the earlier the growth starting point, and the better the growth.

Pay close attention to the food. The growth of fish fingerlings is particularly fast in the early stage, and feeding should be intensified at this time, and some fishermen have a feeding rate of more than 10% at this stage.

Day-to-day management. We should do a good job of "three patrols and four inspections" in the morning, noon and evening, and at the same time, we should also regularly inject water and do a good job in flood prevention and escape prevention.

The difference between wild carp and farmed carp is the color of the scales, fins and tail; body type and stature; the color of the gills; Feel; Meat quality and texture.

1. Scales, fins and tail color.

Wild carp scales, fins and tails are bright in color, whether yellow or red, while carp in cages, reservoirs or ponds are darker in fins. It may not be much different from a distance, but there is a big difference from a closer look.

2. Body shape and stature.

Wild carp are elongated, which has a lot to do with their long-term exercise and eating habits, wild carp need to find food on their own, and many times they are still hungry. And raising carp does not worry about food and clothing, every day when the meal comes to Qi to dig the mouth clothes to open the hands, too lazy to exercise, slowly grow into a bucket waist, fat body.

3. The color of the gills.

The gills of wild carp are bright red, even those of wild carp in places with poor water quality. The gills of carp are very dark in color, without any luster, and some are even dark.

4. Hand feel. When you buy fish, you can feel 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 meat of reared carp is rough and loose, and it feels completely different in the mouth.

The difference between wild carp and farmed carp is manifested in body size, meat quality, growth cycle, wild carp activity is larger, and food ** less, slender body, meat tight, and light color, long growth cycle, while farmed carp activity is small, food ** rich, body fat, soft meat, and bright color.

1. Different body types

Wild and farmed carp differ in size, meat quality and growth cycle. Among them, wild carp should prey on their own, with a large amount of activity, firm flesh, slender body and light color, and a long growth cycle, while the farmed carp is fed by artificial, with small activity, fat and tender meat, fat and bright color, and short growth cycle.

2. Breeding environment

Breeding carp should choose a pond with open terrain, ventilation and sunshine, and convenient drainage and irrigation, and clean up the silt and weeds in it, cover the net with drainage and irrigation masks, and then put the carp into it, and control the water depth at about two meters, so that the carp can grow healthily.

3. Serve food

Carp feed on aquatic weeds, algae, benthic animals, plankton in the water, and can provide carp with greens, melon peels, wheat bran, rice bran, earthworms and other foods when artificially cultivated, and feed twice a day to provide the carp with the nutrients needed for a day.

4. Clean up regularly

When breeding carp, it is necessary to regularly clean up the food residues and feces in the pond to avoid producing harmful gases and affecting the growth of carp, and when the climate is hot, it is necessary to change the water every two days to avoid insufficient oxygen in the water, resulting in the death of carp due to lack of oxygen.

Differences: First, the body type is different, the farmed carp appears fatter because of the sufficient feed and less swimming, and the body is wider, shorter and thicker, while the wild carp appears thin and long because of its own foraging and constant swimming.

Second, the skin color is different, and the color of the farmed carp is lighter, which is not as bright as the wild fish. It is also important to note that due to the increasing pollution, the quality of the wild is not better than that of standardized production.

First, the body type is different.

1. Wild carp: Because it forages for food and swims constantly, it appears slender and elongated.

2. Cultivated carp: due to sufficient feed and less swimming, it appears fatter and has a wider, shorter and thicker body.

Second, the color is different.

1. Wild carp: Wild carp are brightly colored.

2. Farmed carp: The color of farmed carp is lighter.

Third, the fish whiskers are different.

1. Wild carp: The end of the snout at the lower part of the mouth of the wild carp is close to the eye socket.

2. Breeding carp: the end of the carp's hind whiskers is only half of the distance from the eye socket.

The color of the snout whiskers, scales, lower lobes of the tail fin and anal fin at the bottom of the mouth of the carp is an important factor that distinguishes wild carp from forage carp.

First, the end of the snout at the lower end of the snout at the mouth of the wild carp is close to the eye socket, but the end of the hind whiskers of the feed carp is only half the distance from the eye socket. Secondly, the scales of wild carp are yellow in color, and the feed carp are blue-gray.

Finally, there is a clear difference in the color of the lower half of the caudal fin and the anal fin, with wild fish showing a more vivid orange-red color and forage fish being black-gray and slightly reddish.
