CATDOLL : CATDOLL: What is the difference between carp and silver carp?

1. What is the difference between carp and silver carp?

There is not much difference in nutritional value between carp and silver carp. They are almost the same. However, compared with carp, silver carp and silver carp have some characteristics in taste and meat quality. Generally speaking, carp meat has more bones and fewer bones. The characteristics of carp meat are crispy and tender, delicious and of good quality. There are many ways to cook carp, mainly braised, dry-fried, and sweet and sour. Silver carp is the opposite of carp. It has many small bones and is not suitable for children. However, silver carp is also soft, tender and delicate.

Silver carp: also known as silver carp, water carp, jumping carp, and silver carp, belongs to the Cypriniformes, Cyprinidae, and is one of the four famous carps. It has a flat and slightly high body shape, a spindle shape, a blue-gray back, and white sides and abdomen. It has a large head. The eyes are very low. The scales are small. The horny ridge in the middle of the abdomen extends from the bottom of the pectoral fin to the anus. The pectoral fin does not exceed the base of the pelvic fin. The color of each fin is grayish white. The shape is similar to that of bighead carp. Silver carp is impatient and good at jumping. Silver carp is a large freshwater fish raised artificially. It grows fast, has few diseases, and has a high yield. It is often mixed with grass carp and carp. Its meat is tender and nutritious, and it is one of the excellent fish species that is more suitable for breeding. It is one of the main freshwater farmed fish in my country. It is distributed in major water systems across the country.

Carp: Also known as carp crook, carp. A sturdy green-brown fish of the Cyprinidae family, scientific name Cyprinus carpio. Native to Asia, it was introduced to Europe, North America, and other regions. It has large scales and two barbels on each side of the upper jaw. It lives alone or in small groups in calm ponds, lakes, and rivers with muddy bottoms covered with aquatic plants. It is omnivorous and often muddies the water when digging for food, increasing turbidity and having adverse effects on many plants and animals. Therefore, it is often considered unwelcome and people have to spend a lot of effort to get rid of it.

The two fish are completely different. The silver carp has a big head, small scales, a green back and a silvery-white belly. The carp has short whiskers at the corners of its mouth, a relatively small head, and scales that are much larger than those of the silver carp. The color is dark yellow and red, especially the tail, which is a distinct orange-red.

3. What types of fish are there?

There are about 20,000 species of fish in the world, of which about 73 belong to the Cyclostomes, about 800 belong to the Chondrichthyes, and about 20,000 belong to the Osteichthyes.

There are about 3,000 species of fish in my country, of which there are about 2,100 marine fish and about 1,010 freshwater fish.

Fish taxonomy is to classify such a wide variety of species and find out their systematic evolutionary relationships. Its basic task is not only to identify fish and identify their names, but also to explore the similarities and differences between fish and the extent of their similarities and differences, and then study the relationship and classification system of species, the origin and distribution center of species, and the possible process and trend of fish evolution.

It is a necessary basic knowledge for fishery research. When conducting fish resource surveys and developing new fishery objects, it is necessary to have a classification understanding of the objects being studied. As a student majoring in aquaculture, one of the main tasks in the future is to carry out fish breeding. When carrying out this work, fish taxonomy is indispensable. What species are cultured in different water bodies is directly related to economic benefits. In order to breed fish with economic value, correct identification of species is an indispensable task.

This work was done very little before liberation, but after liberation, a lot of investigation and research was carried out, and the fish fauna of major sea areas, rivers, lakes and reservoirs were basically understood, and fish histories of various sea areas were published. Fish histories of some provinces and regions, "Cyprinid Fishes", "Chinese Chondrichthyes" and other monographs were also published one after another.

Section 1: Classes and categories of fish classification

The classification of fishes is the same as that of other organisms. Under the phylum Chordata, there are subphylum, superclass, class, subclass, superorder, order, suborder, superfamily, family, subfamily, genus, subgenus, species and subspecies. The basic unit is species, which is composed of similar species into higher-level categories.

1. Definition of species

Morphology: Species of the same species should have the same characteristics in terms of morphological structure.

Biology: Physiological similarities are primary, i.e., species are groups of natural populations that can interbreed in nature. These groups are reproductively isolated from other such groups.

There are two basic requirements for species identification: (1) distinct characteristics (discontinuity), with no intermediate types; and (2) stable characteristics (invariance).

Species are the basic units of biological evolution and therefore the basic elements of classification. They develop in isolation through interspecific discontinuities. Discontinuities are relative. There are basic interspecific discontinuities, as well as larger discontinuities at the genus, family, and order levels. In summary, the definition of species is: species are reproductive units, consisting of continuous and discontinuous populations; species are both evolutionary units and taxonomic units.

Subspecies is the only taxonomic level below species and is also the reproductive unit of species. Subspecies have certain morphological characteristics and geographical distribution. They are populations formed after individuals within a species are fully isolated geographically and reproductively. Subspecies can interbreed.

1. The concept of genus

A genus is a group of taxonomic units that include one or a group of species that are presumed to share a common morphology.

There are definite gaps between families, and many families are distributed worldwide. Restricted by the type genus, if the type genus name changes, the family name must also change. According to the international nomenclature rules, the family level is the highest level of nomenclature restricted by the actual genus, species and type specimens.

2. The concepts of order, class and phylum

Order, class, and phylum have been proven to be the most stable elements in the classification system. Like genus and family, there are also gaps between them. They are not limited by the model genus and species.

In summary, a genus is a group of related species, a family is a group of related genera, and an order is a group of related families. Each of these groups is composed of lower units that have a series of biological and structural characteristics that distinguish them from other groups.

According to general practice, scientific names such as orders and families are represented by certain suffixes, and Berg's opinion is generally adopted.

my country has abundant freshwater fish resources, and with artificial breeding, the market supply is sufficient. Among them, carp, silver carp, grass carp and black carp are the most common, in addition to eels and turtles.

Carp is a kind of fine freshwater fish. Its scales are white with metallic luster, it has a red tail, tender meat and delicious taste. The Yellow River carp is especially popular.

Grass carp is also called grass green, with a tea yellow body color. It is the most productive freshwater fish. This fish is characterized by fast growth, heavy weight, big head and fat meat, but the meat is coarse and of lower quality than carp.

Silver carp is divided into two types: silver carp and bighead carp (commonly known as fathead fish). Silver carp has a white body color, small scales, a large head, fat meat, and delicious taste. The head is the fattest, especially suitable for making casserole fish head.

Crucian carp is also called crucian carp. It has a flat and wide body, a prominent back bulge, and small scales. It is characterized by tender meat and great flavor, but it has many small bones. Crucian carp is most suitable for boiling soup. Small crucian carp is suitable for making crispy fish.

Black carp, also known as blackfin, has a long, cylindrical body, a black spine, a milky white belly, and white, plump flesh. It is one of the freshwater fish with the most tender meat. It contains a lot of fat, especially the meat from the pectoral fin and the head and tail. The black carp's lung is the most tender part of the fish body and contains a lot of fat. The famous dish "Roasted Bald Lung" is made with black carp lungs. It is cooked and eaten hot, and is extremely delicious.

The eel, also known as long fish and yellow eel, has a long and thin body, a thick head and a thin tail, a dark-brown back, a yellow belly, small eyes and no scales. The meat of this fish is extremely tender and delicious, and is regarded as a top-quality fish.

The soft-shelled turtle, also known as the turtle fish, has tender meat and rich nutrition, and is a high-end tonic.

Ornamental fish refers to those fish with bright colors or peculiar shapes that have ornamental value. They are usually composed of three major strains, namely temperate freshwater ornamental fish, tropical freshwater ornamental fish and tropical marine ornamental fish.

Temperate freshwater ornamental fish mainly include red crucian carp, Chinese goldfish, and Japanese koi. There are three major series of tropical freshwater ornamental fish: the first is the lantern species, the second is the angelfish, and the third is the dragon fish. Marine ornamental fish mainly come from the coral reef waters of the Indian Ocean and the Pacific Ocean. They are of many varieties and strange colors, with a primitive, simple and mysterious natural beauty.

To put it simply, they are generally divided into freshwater fish and marine fish. Freshwater fish are divided into edible fish and ornamental fish, and marine fish are divided into thermal conductivity fish.
