Which giant freshwater fish are common on the mainland? Chinese sturgeon, white sturgeon? No, no, no, they are migratory fish, not really freshwater fish, so which ones are? I'll tell you in this issue!
Darcher's rays
Megalops cyprinoides, also known as eelfish, migratory carps, eels, silverfin herring, largemouth herring, silver scale fish, etc., is a large migratory fish belonging to the family Megalops, with a body length of 2 meters and a weight of 100 kilograms. It is found in tropical and subtropical coastal waters, estuaries and offshore areas, mainly in the Pacific, Indian and Atlantic Oceans.

It has a fusiform body with a raised back and a flat abdomen that is flattened and long. The head is large, the mouth is wide, and the eyes are small. The body surface is silvery with smooth scales. The dorsal and fins are particularly broad at the base, and the pectoral and ventral fins are smaller. One of the characteristics of the darling is that it has a very strong swimming ability and jumping ability, and can jump out of the water up to 2 meters or more, which is a very spectacular marine life.
Darchendelli is a very important commercial fish that is loved for its delicious meat and nutrients. At the same time, it is also an important game fishing species, which is widely used for sea fishing and freshwater fishing.
Giant ray
Mola mola is a large marine bony fish belonging to the order Cyprinids, also known as sunfish, sea moonfish, moonfish, etc., and is one of the largest bone fish in existence. Distributed in temperate and tropical waters of the world's oceans, the giant ray is an offshore and offshore fish that is also commonly found along the coast. The giant ray usually has a disc-shaped body, is about 2 meters long and weighs up to 1000 kilograms, making it a very large fish.
The giant ray has a small head with a large mouth, small teeth and no caudal fin. Their body surface appears brown or gray, with a raised back and flattened body sides. The dorsal and fins on both sides of the giant ray are very large and triangular in shape, and are used for swimming. The dorsal and fins of the giant ray are connected into a long fin ridge and float on the surface of the water like a disc, so it is also called "zooplankton".
The giant ray is an herbivorous fish that feeds mainly on phytoplankton and small invertebrates. They often bask in the sun on the surface of the sea and sometimes jump out of the water. The giant ray is a very mysterious creature that is often targeted by explorers and tourists.
herring
Pseudosciaena crocea is a large marine demersal fish belonging to the perch family, and is one of the important economic fish in the South China Sea and East China Sea. Bluefish is distributed in the waters of the South China Sea, East China Sea and the Sea of Japan, and is a warm and warm marine fish with a wide range of adaptations. Blue fish are large, generally about 50-60 cm long, the largest can reach 130 cm, and weigh about 40 kg. Bluefish is also a good edible fish, with delicious meat and rich nutrients.
The bluefish is slender , with flat sides , a slightly raised back , and long dorsal and fins. Blue fish have a large head, a large mouth, sharp teeth, and are adapted to prey on underlying organisms. The body of the blue fish is light gray or light blue, with dark longitudinal stripes on the body surface and a distinct lateral line. Blue fish grow faster, the sexual maturity period is about 2-3 years, and the life expectancy can reach more than 10 years.
Blue fish live in the deep water area of the seabed and mainly feed on benthic animals such as shrimp, crabs, shellfish, etc. Bluefish is caught in large quantities and is an important economic fish. In order to protect bluefish resources, the government has implemented a series of protective measures in the South China Sea and the East China Sea, such as banning night fishing and banning the use of some fishing tools. At the same time, it is also studying how to improve the efficiency of blue carp farming, so as to reduce the pressure on wild resources.
Big red fish
The great red fish (scientific name: Lutjanus sebae) is a large demersal fish belonging to the perch family, mainly distributed in the tropical waters of the Indian Ocean and the western Pacific Ocean, including East Africa, the Red Sea, the Arabian Sea, Indonesia, Malaysia, the Philippines, the South China Sea and other places. Big red fish is a high-quality edible fish with delicious meat and rich nutrition, which is deeply loved by people.
The large red fish is large, generally about 50-100 cm long, up to 2 meters in size, and weighs up to 50 kg. The body of the big red fish appears red or yellow-red, with pale horizontal stripes or spots on the side of the body, and the lateral line is distinct. The big red fish has a large head, a large mouth, sharp teeth, and is adapted to prey on the underlying organisms. The dorsal and fins of the great red fish are long, and the pectoral and ventral fins are small.
The great red fish lives in seabed areas such as coral reefs and rocky reefs and is a carnivorous fish that feeds on small invertebrates and small fish. The breeding period of the big red fish is generally from June to August every year, during which the male big red fish will change color and brighten to attract females. The sexual maturity period of the big red fish is about 3-4 years, and the lifespan can reach more than 20 years.
Carp
Ganoid fish is an ancient fish that has been around for at least 200 million years. Their body bones are made up of hard bony plates, also known as scales, which are different from modern fish. Carp can live in both fresh and seawater and can grow to be very large, with the largest species growing up to 4 meters long.
Their most distinctive feature is their scale armor, which protects their bodies from injury and predators. The scale armor of carp is sometimes used to make ornaments, such as shawls and fish scale chains.
Carp have teeth inside their mouths, and they can eat small fish, crustaceans and shellfish, among others. They have a special stomach that helps digest hard foods such as shells and crustaceans. During the breeding season, carp swim to shallow areas of rivers or lakes to spawn, and males make noises in the water to attract females.
Carp has undergone a lot of changes over the past few million years and now only a few species remain. They play an important role in ecosystems as they can help maintain the ecological balance of waters. Carp is also an important object of paleontology and evolutionary biology research.
Bighead carp
Bighead carp (English name: Sturgeon) is a large freshwater fish belonging to the sturgeon family, a very ancient fish that has been around for at least 200 million years. Their bodies are long and round, covered with hard scales that protect them from injury and predators. Bighead carp usually live in deep water and can grow to be very large, with the largest species growing up to 6 meters long.
Bighead carp have a long, flat mouth with a row of sharp teeth that help them prey on small fish, crustaceans, shellfish, etc. They also have a special stomach that helps digest hard foods such as shells and crustaceans. Bighead carp swim to shallow areas of rivers or lakes to spawn during the breeding season, and males make noises in the water to attract females.
Bighead carp is a very precious ingredient, bighead carp is delicious, rich in protein and nutrients, and is a favorite ingredient for many gourmets. Caviar is also an important by-product of bighead carp, which is made from the eggs of bighead carp and is a very expensive delicacy.
Due to overfishing and ecological changes, many bighead carp species are now threatened with extinction. Many countries have taken measures to protect bighead carp, such as limiting fishing and captive breeding. Bighead carp has also become an important object of paleontology and evolutionary biology research.
catfish
Catfish (English name: Catfish) is a freshwater fish that belongs to the catfish family and is a fish that is widely distributed around the world. Their bodies are long, round, usually covered with tiny scales, and have a flat mouth on their head with a row of sharp teeth that help them prey on small fish, crustaceans, shellfish, etc. Catfish can live in both fresh and salt water, and the largest species can grow to more than 2 meters long.
