CATDOLL : CATDOLL: What is the difference between catfish and catfish?

What is the difference between catfish and trevally?

The difference between tuna and catfish is that they have different habitats, different appearances, and different nutritional values.

1. Different Habitats

1. T-fish: T-fish is a long-snouted t-fish, which is a bottom fish. It often lives in river bends with slow currents, deep water, and many rocks. It hides at the bottom of the water or in cracks between rocks during the day and goes out to look for food at night. It also moves in the middle and lower layers of the water body when looking for food; it hibernates in the cracks between gravels in deep water of the main stream in winter.

2. Catfish: Freshwater catfish are distributed in various freshwater areas around the world, while saltwater catfish live near tropical coasts.

2. Different appearance

1. T-fish: T-fish is a long snout fish, with an elongated body, short and thick in the front and flat in the back. The head is slightly large, with a raised back and not covered by a membrane; the upper occipital spine is rough and exposed. The snout is quite pointed and prominent, tapered. The mouth is inferior and arc-shaped. The lips are thick. The upper jaw protrudes beyond the lower jaw. The eyes are small, located laterally and the eye margins are not free and covered by a membrane.

The interorbital space is wide and convex. The nasal barbels are located at the front edge of the posterior nostril, and the rear end reaches the front edge of the eye. The gill openings are large. The gill cover membrane is not connected to the gill septum. The gill rakers are small. The body is smooth and scaleless. The dorsal fin is short, and the bony spurs have a smooth front edge and serrated rear edge; the spurs are longer than the pectoral fin spurs, and the starting point is located vertically above the rear end of the pectoral fin.

2. Catfish: Catfish has no scales, has a lot of mucus on its body, a flat head and a wide mouth, and has 4 whiskers on each upper and lower jaw.

3. Different nutritional values

1. Longnose tuna: The meat of the longnose tuna is tender and delicious, rich in fat, and has no small bones. The protein content is 13.7% and the fat content is 4.7%. It is known as the top freshwater edible fish.

2. Catfish: Catfish is rich in nutrients. According to measurements, every 100 grams of edible catfish contains 14.4 grams of protein, 2.1 grams of fat, 64.1 grams of water, as well as carbohydrates, calcium, phosphorus, iron and other nutrients.

Is there a difference between catfish and mullet?

The mullet is a species of catfish. There is no difference.

The long-snout dart (Leiocassis longirostris) belongs to the order Siluriformes, family Ctenidae, genus Cten, also known as t fish. T fish has different names in different places, such as "t mouse" in Shanghai, "Jiangtuan" in Sichuan, and "Xiyu" in Guizhou. The long-snout dart has a long body, a conical snout, and protrudes significantly forward. The mouth is inferior, crescent-shaped, with thick lips and small eyes. There are 4 pairs of small whiskers. It is scaleless, and the back edge of the hard spines of the dorsal and pectoral fins is serrated, the adipose fin is thick, and the caudal fin is deeply forked. The body color is pink, the back is slightly gray, the abdomen is white, and the fins are gray-black.

Additional information

Generally, it lives at the bottom of rivers and streams, and also moves in the middle and lower layers of water bodies when foraging. In winter, it mostly hibernates in the cracks of gravel in the deep water of the main stream. Long-nosed dace is a carnivorous fish, and its main food is small fish and aquatic insects. The minimum age to reach sexual maturity is 3 years, and it is generally 4 to 5 years. Adult fish begin to mature in March and April every year, and then swim upstream to the rapids of the river with gravel bottom to spawn. The spawning period is from April to June, and retreats around August. The number of eggs varies from 10,000 to more than 100,000. The spawning grounds of the Yangtze River are concentrated in the Jingjiang River bend in the middle reaches and the Tuojiang River in the upper reaches.

Usually 300-500 mm, with rapid growth in the first 4 years and slow growth in the last 4 years. Long lifespan. The oldest known age is 22 years old, sexual maturity is late, and the youngest mature age is 3 years old. The spawning period is from December to January of the following year, and the water temperature is about 2℃ during spawning. When spawning, the sandy or gravelly river beach 1-3 meters below the ice is chosen for spawning. Burbot living in lakes also migrate to the river to spawn.

During spawning, the male fish arrives at the spawning ground first, and the female fish comes after 3-4 days. The male fish often circles around and chases the female fish. After circling, the male and female fish shake their bodies to lay eggs and ejaculate. Spawning activities are mostly carried out at night. The number of eggs carried varies greatly with the size of the fish body. A body length of 340 mm can carry 57,000 eggs, and a body length of 870 mm can carry 3 million eggs. The incubation period of fry is long, about 60 days, and the newly hatched fry is 3.8-4.3 mm long. It is a ferocious carnivorous fish and a nocturnal feeder. The 50 mm long juvenile fish feeds on the larvae of plankton, hair-winged fish, dipteran fish, etc. The adult fish feeds entirely on fish. It is almost non-selective and cannibalize each other when food is scarce.

The longnose d is a fast-growing fish, the largest of its kind, with the largest individual reaching 15 kg, and the most common ones weighing 2 to 4 kg. It accounts for a large proportion of the catch in the Yangtze River Basin, and the middle and lower reaches are significantly more than the upper reaches.

Differences between tuna and catfish

1. Head Difference

Compared with tuna and catfish of the same weight, the head of tuna is obviously smaller than that of catfish. The body of catfish is flat, and the body of catfish is smaller than the head.

2. Tail Difference

The tail of t fish is forked like grass carp, carp and other fish, while the tail of catfish is round, which is an easy distinction.

3. Fin Differences

The tuna has two dorsal fins, one in front and one behind, and the fin at the front of the tail is fleshy; while the catfish has only one small fin on its back.

Generally speaking, the difference between tuna and catfish is the difference in their head, tail and fins, which are easy to distinguish if you look carefully.

1. Characteristics of t-fish

The body is long, the snout is conical, and it protrudes forward significantly. There are 4 pairs of small whiskers. It is scaleless, and the back edge of the hard spines of the dorsal and pectoral fins is serrated. The adipose fin is thick, and the caudal fin is deeply forked. The body color is pink, with a slightly gray back, a white abdomen, and gray-black fins.

2. Characteristics of catfish

The body is long, the head is flat, and the tail is laterally flattened. The mouth is inferior, the mouth cleft is small, and the end reaches only below the front edge of the eye. The lower jaw is prominent. The teeth are thin and velvety, and the jaw teeth and pear teeth are arranged in a curved band. The pear bone tooth band is continuous, and the middle of the rear edge is slightly concave.

The eyes are small and covered with membranes. Adults have 2 pairs of 4 barbels. The upper barbels can reach the end of the pectoral fins, and the lower barbels are shorter. Juveniles have 3 pairs of barbels. When the body length reaches about 60 mm, the chin barbels begin to disappear. Catfish are mucus-rich and scaleless. The dorsal fin is very small, without hard spines, and has 4 to 6 fin rays. There is no adipose fin. The anal fin is very long, and the rear end is connected to the caudal fin. The body color of catfish is usually dark brown or gray-black, with slightly dark cloud-like spots.

What is the difference between the two fish, t-fish and catfish, in appearance? This question is a matter of opinion, because everyone has different aesthetics, and there are a thousand Hamlets in the hearts of a thousand readers. Everyone has different ideas, so there are many answers to such questions. The author's opinion may not be correct, but I will tell you my own opinion on this question.

These two kinds of fish are often eaten in our daily life, and many hot pot restaurants or fish soup bases will have these two kinds of fish, because their meat is relatively fresh and tender, but there are still some differences between them. The main points are as follows.

The first difference is that their tails are different. The catfish's tail is more like a round fan, while the tuna's tail is basically forked like that of ordinary fish, so tuna is also called river grouper, fathead fish, etc.

The second difference is that their heads are also different. Generally, the head of catfish is larger than that of tuna, and the head of catfish is relatively flat, and generally its head is larger than its body.

The third difference is in the fins. Catfish has only one dorsal fin on its back, and this dorsal fin is relatively small, while tuna has two dorsal fins, one in the front and the other at the tail, and the catfish has a fleshy dorsal fin at the tail.

The above is about the differences between t fish and catfish in appearance. In addition, there are some differences in their cooking methods. T fish can be steamed with chopped pepper or fermented black beans, braised with sauce, or grilled. Its meat is relatively tender, without bones, and the fish bladder is relatively thick.

Catfish is commonly cooked by steaming, and is also often used in stews, meatballs, etc. It also has relatively few fish bones.

The above is my personal immature opinion on this issue and does not represent any reference suggestions. If there are any inappropriate or incomplete points, I hope you will criticize and correct me.

The catfish is a species of catfish.

Catfish, same as catfish. There are many species, the most common ones are catfish (native catfish), bigmouth catfish, bearded catfish (pond catfish), leather bearded catfish (Egyptian bearded catfish), Hakka commonly known as sliding brother fish. Catfish, Animal Kingdom-Chordata-Chordata-Chordata-Acto-finned Fish-Siluriformes-Siluridae-Silurus-Silurus-Species. There are 4 whiskers on the mouth, the upper ones are long and the lower ones are short. They are carnivorous, mostly wild, and do not require high water quality. They can be artificially cultivated. They grow fast, and some species can grow to be very large.

The long snout dart (Leiocassis longirostris) belongs to the order Siluriformes, family Siluriformes, genus dart, also known as t fish. T fish has different names in different places, such as "t mouse" in Shanghai, "Jiangtuan" in Sichuan, and "Xiyu" in Guizhou. The long snout dart has a long body, a conical snout, and protrudes forward significantly. The mouth is inferior, crescent-shaped, with thick lips and small eyes. There are 4 pairs of small whiskers. It is scaleless, with serrations on the back edge of the hard spines of the dorsal and pectoral fins, a thick adipose fin, and a deeply bifurcated caudal fin. The body color is pink, with a slightly gray back, a white belly, and gray-black fins.

The difference between the two is that the troll has a relatively small head, two dorsal fins, and a forked tail; the catfish has a relatively large head, only one dorsal fin, a round fan-shaped tail, and a lot of mucus on the body surface, so it can be quickly distinguished by the dorsal fin.
