CATDOLL : CATDOLL: Is there a difference between grouper and snakehead?

There is no difference between grouper and black fish, they are the same fish. Grouper, also known as black fish, grouper, black stick, raw fish, snakehead fish, filial fish, inkhead fish, and wealth fish, is a common edible fish in my country. It is large in size, grows fast, and has high economic value.

This fish is commonly found in China. It inhabits still or slightly flowing water with dense aquatic plants and soft bottom mud. It is found in lakes, rivers, reservoirs, ponds and other waters. The grouper fish is highly adaptable to changes in environmental factors in the water, especially to hypoxia, changes in water temperature and poor water quality. Its body is cylindrical in the front and flat in the back; its body length is generally 25 to 40 cm; its head is long, slightly flat in the front and slightly raised in the back; its body color is gray-black, with darker back and top of the head, pale white abdomen, and irregular black spots on each side of the body.

Fish are highly adaptable to changes in environmental factors in water bodies, especially to hypoxia, changes in water temperature, and poor water quality. When the water body is hypoxic, it can expose its head above the water surface and breathe oxygen in the air directly with the help of the supragillary organs in the gill cavity. Even in the case of little water or even out of water, as long as the gills and body surface are kept at a certain humidity, it can still survive for a long time. The survival water temperature of the spotted fish is 0℃-41℃, and the optimum water temperature is 26℃-28℃. When the water temperature reaches above 8℃ in spring, it often moves in the middle and upper layers of the water body. In summer, it often moves in the upper layers of the water body. When the water temperature drops below 6℃ in autumn, it swims slowly and often lurks deep under the water. When the water temperature is too low in winter, it buries the back half of its body in the mud or haystack, with its head exposed in the water without eating or moving. The grouper has a strong jumping ability. When the weather is hot and humid, or when it rains and the water level rises, the grouper will often jump out of the water and escape along the embankment. When there is a flow of water, it will often stimulate the fish to jump and escape. When escaping, its body is like a snake, moving slowly forward.

Snakehead fish are ferocious, bottom-dwelling, carnivorous fish that prefer shallow waters with lush aquatic plants. Snakehead fish are delicious and nutritious, and are very popular among consumers. They are a fish with high economic value. They can remove blood stasis, promote new blood circulation, nourish the body, promote muscle growth and blood circulation, and promote wound healing. They have high medicinal value. my country has a long history of eating snakehead fish. As early as 2,000 years ago, it was listed as a top-grade insect and fish in the Shennong Herbal Classic. [4]

Morphological characteristics

The front part of the body of the snakehead is cylindrical, and the back part is laterally flattened. The head is long, slightly flattened in the front part, and slightly raised in the back. The snout is short and blunt, the mouth is large, terminal, and the mouth cleft is slightly oblique and extends to the lower edge behind the eye. The lower jaw is slightly protruding. The teeth are small and arranged in a band-like manner on the upper and lower jaws. The teeth on both sides of the lower jaw are strong and sharp. The eyes are small and located on the upper side, located in the front half of the head, quite close to the tip of the snout. There are two pairs of nostrils. The anterior nostril is located at the tip of the snout and is tubular, and the posterior nostril is located above the front of the eye and is a small round hole. The gill slits are large, and the left and right gill membranes are fused and not connected to the cheeks. The gill rakers are thick and short, and are sparsely arranged. There is an auxiliary suprabranchial organ on each side above the gill cavity, which can breathe air. [6]

Snakehead

The body color is gray-black, with the back and top of the head being darker, the abdomen being pale white, and the sides of the body having irregular black spots, and the sides of the head having two rows of black spots. The odd fin has black and white spots, while the even fin is gray-yellow with irregular spots. The whole body is covered with medium-sized round scales, and the top of the head is covered with irregular scales. The lateral line is straight, with a small bend above the anus, and two rows of scales move downward, running in the middle of the side of the body and extending to the tail. [6]

The dorsal fin is quite long, almost connected to the caudal fin, without spines, and starts from above the base of the pectoral fins, close to the tip of the snout. The pelvic fins are short, starting from below the 4th to 5th dorsal fin rays and ending not reaching the anus. The pectoral fins are rounded, with the fin tips extending beyond the middle of the pelvic fins. The anal fin is shorter than the dorsal fin, starting from below the 15th to 16th pain fin rays. The caudal fin is rounded. The anus is located just in front of the anal fin. There are 49 to 54 soft rays in the dorsal fin and 32 to 38 soft rays in the anal fin. [6]

The swim bladder is single-chambered, slender, rounded at the front and pointed at the end, extending to above the base of the anal fin. The stomach is sac-shaped, with two pyloric protrusions, thick and long, about one-third of the intestine. The intestine is short and hyperbolic, longer than half the body length. [6]

The main characteristics of the Heilongjiang subspecies are: the back is dark green-black, with irregular black-green spots on the sides of the body, the dorsal and caudal fins are the same color as the back, and the pectoral and anal fins are lighter in color.[6]

The main differences between the Channa argus and the Channa scorpion are that the body of the Channa argus is longer, while the body of the Channa scorpion is shorter. The markings on the top of the heads of the two are also significantly different: the Channa argus has seven star-shaped markings on the top of its head, while the Channa scorpion has markings similar to the Chinese character "一８８" on the top of its head. In addition, the head of the Channa argus is longer and more pointed, more like a snake. [6]

Distribution

Snakehead

Overseas, Channa argus is mainly distributed in the southern and northern regions of North Korea. In my country, Channa argus has a wide geographical distribution. In addition to the western plateau area, it is also distributed in large numbers in the vast area from the Yangtze River Basin to the Heilongjiang River Basin. In addition, it is also distributed in small quantities in parts of Yunnan Province and Taiwan Province. [7]

Living habits

The black snakehead is a freshwater benthic fish, usually living in waters with dense aquatic plants or silt bottoms, and is found in rivers, lakes, reservoirs, ponds, paddy fields and other waters. It has a strong adaptability to environmental factors in the water body, especially to dissolved oxygen, water temperature and water quality. When there is a lack of oxygen in the water body, it can breathe on the water surface with the help of the auxiliary respiratory organs in the supragillary cavity. The black snakehead can survive in water temperatures of 0~41℃, and 16~30℃ is the optimal temperature for the growth, development and reproduction of the black snakehead. When the water temperature returns to above 8℃ in spring, it usually moves in the middle and upper layers of the water body; in summer, the black snakehead is mostly active in the upper layer of the water body; when the temperature is below 6℃ in autumn, the black snakehead swims slowly and often lurks in the deep water layer; when the water temperature is close to 0℃ in winter, it buries in the silt to hibernate. Since the snakehead has a strong jumping ability, it often escapes. Hot weather, rain, and rising water levels can cause the snakehead to escape. [7]

feeding habits

The black snakehead is a carnivorous fish with a ferocious nature and a large appetite. The prey it eats generally varies with the size of the fish. Juveniles and young fish mainly feed on rotifers, copepods, cladocerans, and chironomid larvae; juveniles mainly feed on larvae of aquatic insects, small fish and shrimps; and adults feed on various small fish and shrimps. The fish it eats vary greatly in different waters, but they are usually the dominant species in that area. For example, the black snakehead in the Heilongjiang River mainly preys on crucian carp, carp, croaker, snapper, and snakehead; in the Yangtze River Basin, it mainly preys on spiny loach, sand loach, loach, crucian carp, and snapper. In addition, the black snakehead has the habit of cannibalism. The amount of food it eats is closely related to the water temperature. When the water temperature is high in summer, the amount of food it eats is very large; when the water temperature is below 12°C, it will stop eating. [7]

No difference, same fish

Channa argus, also known as black fish, grouper, black stick, raw fish, snakehead fish, filial fish, inkhead fish, and money fish, is a common edible fish in China. It is large, fast-growing, and has high economic value. Black fish has few bones, a high meat content, and is rich in nutrients, with a higher protein content than chicken and beef.

1. The difference between the appearance of black fish and grouper

The first difference between the appearance of black carp and grouper is the color. We can easily distinguish the difference from the color. This is the first method, and the simplest method. Grouper, as we all know, has a very oval body and very thin and sharp teeth. Sometimes it looks like canine teeth. The shape of grouper's teeth is very scary, and many children will cry after seeing it. The temperament of black carp is very fierce, and the body length is normal. And we all know that the reproductive capacity of black carp is very strong, and the fish living with black carp often cannot escape its clutches.

2. Difference in nutritional value between black fish and grouper

The nutritional value of black fish and grouper is also very high. We all know that grouper is very nutritious. Its meat is relatively white, very similar to the chicken living in the mainland. I wonder if you have heard of sea chicken? Sea chicken is actually grouper. Grouper is not only very nutritious, but also very expensive. In some areas, it is called one of the four famous fishes in China. In the fish world in China, the status of grouper is very high. The nutritional value of black fish is also very high. Black fish is very suitable for people with weak constitutions because of its high protein content. Some people are weaker or more suitable to eat black fish after surgery. Because this kind of fish is so nutritious.

3. Differences in eating black fish and grouper

Many people also ask me about the way to eat black fish and grouper. Some people think that black fish has such a high status and high nutritional value, and most importantly, the price is very high, so many people dare not try it easily. In fact, the way to cook grouper is the same as that of black fish. You can steam grouper, braise grouper, and cook grouper with pickled cabbage. Black fish can also be steamed, braised, or cooked with pickled cabbage. The cooking methods of fish are the same, and fish can also be made into soup, which tastes very good.
