CATDOLL : CATDOLL: Description of the appearance of crucian carp

1. Description of the appearance of crucian carp

Crucian carp is commonly known as Xitou fish, crucian carp, crucian carp shell, crucian carp seeds, and Buddha crucian carp. Crucian carp is generally 15 to 20 cm long, slightly smaller in size, flat and tall, thicker in body, and round in abdomen; with large eyes and mouth at the front; short head, blunt snout; no whiskers; large scales; slightly curved lateral line, long dorsal fin; generally the back of the body is blue-brown, the belly is silver-gray, and the fins are off-white. Due to different growth waters, the body color varies in depth, and the color gradually transitions from gray on the back to off-white on the abdomen. Crucian carp is a small and medium-sized fish that grows slowly. The body length of a 1-winter fish is 5 cm, the body length of a 2-winter fish is 10 to 14 cm, and the body length of a 3-winter fish is up to 18 cm. The growth rates of male and female fish are different. As they age, female fish grow faster than male fish. There are obvious differences in the growth of crucian carp in different waters. Under natural conditions, the characteristics of crucian carp living in different waters have certain changes and differentiation, forming local species of crucian carp or various excellent varieties through artificial breeding. From the perspective of fish growth, crucian carp can be divided into two categories: one is low-body, with body height less than 40% of body length, usually growing slowly, mainly wild crucian carp, etc. The other is high-body, with body height more than 40% of body length, growing faster. Artificially cultivated crucian carp in my country are all high-body

2. What are the differences between carp and crucian carp?

The differences between carp and crucian carp include different families, appearances, fish lips and distribution ranges.

1. Different families

Carp belongs to the genus Carp, also known as carp, carp, hairy carp, and red fish; crucian carp is a general term for animals under the genus Carp of the family Cyprinidae.

2. Different appearance

The carp is slightly larger in size, with flat sides, a round abdomen, a short head, a blunt snout and long gill rakers, slender gill filaments, a gray-black back, a slight bulge in front of the dorsal spine, a color close to yellow or black below the lateral line, a white abdomen and a slightly black dorsal spine.

The ventral surface of the crucian carp is silver-gray, the dorsal surface is bluish-brown, and all the barbels are grayish-white. It looks like a carp, but its body is taller. Both the dorsal and anal fins have hard spines, and the rear edge is serrated. The biggest difference between it and the carp is the whiskers. The carp has four whiskers in its mouth, a pair of rostral whiskers, and the mandibular whiskers are twice as long as the rostral whiskers.

3. Fish lips are different

Carp has two pairs of whiskers and three rows of throat teeth; crucian carp has thin lips with little flesh and no whiskers around its mouth.

4. Different distribution ranges

Carp is native to Asia and was later introduced to Europe, North America and other regions. It is distributed all over the world except Australia and South America. It is one of the freshwater fishes with the most varieties, the widest distribution, the highest yield and the longest breeding history. It lives alone or in small groups in calm lakes, ponds and rivers with muddy bottoms covered with aquatic plants.

Crucian carp is widely distributed throughout the country (except the western plateau). It is an excellent farmed fish and economic fish in my country. It is produced all year round in waters across the country. It lives in canals, swamps, lakes, and rivers, especially in shallow lakes and ponds with lush aquatic plants. It is a highly adaptable fish with a strong reproductive capacity.

3. Is crucian carp a grass carp? What is the difference between them?

Crucian carp is not grass carp. Although they are both common freshwater fish, they are not the same kind of fish. Although there are many similarities between the two, such as the same class, order, and family to which they belong, and certain similarities in appearance, this does not mean that they are the same kind of fish. In fact, crucian carp belongs to the genus Carp, and grass carp belongs to the genus Grass Carp. This clearly shows that the two are not the same kind of fish. 1. Is crucian carp grass carp? Crucian carp and grass carp are both common and widely distributed freshwater fish and can be eaten. In my country, crucian carp and grass carp can be seen almost everywhere. Both are fish that can be artificially bred, and they are bred on a large scale. However, crucian carp is not grass carp. Although there are many similarities between the two, such as the same class, order, and family to which they belong, and certain similarities in appearance, the two cannot be confused because of this. In fact, in addition to these similarities, they are also different in many aspects, and they can be distinguished from many aspects.

2. What is the difference between crucian carp and grass carp? 1. Genus difference: Although crucian carp and grass carp are both fish in the class of bony fish, order of Cypriniformes, and family of Cyprinidae, they belong to different genera. Crucian carp belongs to the genus Carp, while grass carp belongs to the genus Grass Carp, so they are not the same kind of fish.

2. Shape difference: There are differences in the shapes of crucian carp and grass carp. Observing them from the side, we will find that the body shape of crucian carp is slightly flatter, while the shape of grass carp is rounder.

3. Difference in taste and nutritional value: As mentioned above, both crucian carp and grass carp are edible fish, but there are differences in their taste and nutritional value. In terms of taste, crucian carp tastes better and more tender, while grass carp tastes relatively worse. In terms of nutritional value, crucian carp has a higher nutritional value than grass carp.

4. Difference in the number of fish bones: The number of fish bones of crucian carp and grass carp is also different. Although crucian carp tastes better and has higher nutritional value, they also have more fish bones, and there are many small and messy bones, sometimes distributed very irregularly. Therefore, crucian carp is more troublesome to handle before eating.

Difference in nutritional value: Because crucian carp is an omnivorous fish and is very easy to raise, its meat can promote human digestion and stimulate human appetite, which shows that it has many benefits. Grass carp is also very nutritious, but it does not have the high nutritional value and ingredients of crucian carp, and its meat is not as delicious as crucian carp. Different appearance: Grass carp is slightly longer, its body is cylindrical, and its tail is slightly flat. The pectoral fins and caudal fins of grass carp are grayish yellow, and the remaining fins are lighter in color. The body shape of crucian carp is somewhat similar to that of carp, but the snout of crucian carp has no whiskers, but carp has all of them. If you look closely, the back of crucian carp is dark gray, and the sides of his body and the abdomen of his body are silvery white. Precautions for grass carp breeding in summer In summer, fry should be selected nearby, otherwise the mortality rate of breeding will be very high. At the same time, the fry cannot be put into the pond immediately, and they also need to be cleaned and disinfected with drugs to avoid bacterial infection, which can also increase the survival rate of the fry. The density of fry should be controlled when raising fish, generally 800~1000 per mu. If there is an aerator, it can be released appropriately, but the number of aquaculture can also be controlled at 2000 to 3000 as much as possible. Grass carp feeding is mainly to ensure the freshness of the feed, but also to ensure the quality of the feed, there is no residual drug damage or other diseases, which will affect the normal growth of grass carp. When feeding, grass carp should be fed quantitatively and qualitatively according to the laws of weather changes, water quality changes, grass carp feeding, etc.
