1. What are the omnivorous fish?

Omnivorous fish: Omnivorous is also called "generalist". Omnivorous fish have a wide and varied diet, such as carp, crucian carp, mullet, and minnow. Some of them have strong throat teeth that can cut and grind food, like carp; some have less developed throat teeth, like crucian carp; their food composition is relatively wide, and they can eat aquatic plankton, insects, chironomid larvae, algae, benthic animals, animal and plant debris, etc., so this type of fish has a strong ability to adapt to survival.

2. What are the freshwater predatory fish in Chongqing?

There are mainly shell fish, bighead carp, mandarin fish, black fish, catfish, etc.

3. Saprophagous fish?

Saprophagous fish are fish that feed on biological detritus. Representative fish include: carp, dace, pike, mullet, etc.

Carp, this type of fish mainly feeds on dead animals and plants in the water and mud, and also eats benthic algae and invertebrates. In theory, it is a filter-feeding fish similar to silver carp and bighead carp. Carp, pike and mullet belong to this category.

Mud fish is a tropical fish of the order Cypriniformes and family Cyprinidae of the class Actinopterygii. There are many species of dace, commonly known as earth dace, snow dace, dace male, and flower dace. It is also known as snow dace (Compendium of Materia Medica Supplement), dace (Food Materia Medica by Yao Kecheng), earth dace (Compendium of Materia Medica Qiuyuan), etc. Dace can be roughly divided into three types: wheat dace, Thai dace, and earth dace.

Barracuda is a near-shore fish that likes to live in coastal areas, river estuaries or salt water, and can also enter fresh water. Barracuda likes to live in groups, is lively and good at jumping. It often swims upstream in groups in countercurrents and eats organic matter in the mud at the bottom of the water. It is distributed in the South China Sea, East China Sea, Yellow Sea and Bohai Sea.

4. What are filter-feeding fish? What are filter-feeding fish?

Filter-feeding fish: A general term for a class of cold-blooded vertebrates that live in water all their lives, breathe with gills, use fins to assist body balance and movement, and feed on plankton. The most common types of filter-feeding fish are silver carp and bighead carp, two of the four major carps. Silver carp is a filter-feeding fish that mainly feeds on phytoplankton, while bighead carp is a filter-feeding fish that mainly feeds on zooplankton. Both types of fish are particularly suitable for breeding in northern waters, where they grow fast and are used in large quantities.

7. Freshwater herbivorous fish?

Answer: Grass carp

Grass carp, an animal of the genus Grass Carp in the family Cyprinidae of the order Cypriniformes, is included in the "List of Key Protected Economic Aquatic Animal and Plant Resources of China (First Batch)".

It has an elongated body, with a cylindrical front, a flat tail, a round abdomen, and no abdominal ridges. It has a wide, medium-sized head, a slightly flat front, a short and blunt snout, and a snout slightly longer than the eye diameter. Its scales are medium-sized and round, with an arc-shaped lateral line in the front and a straight line in the back, extending to the base of the tail fin. It is a herbivorous fish that lives in rivers and lakes in plain areas. This type of animal is distributed in China, Russia, Bulgaria and other countries.

8.What are herbivorous fish?

There are several types of fish. (1) Herbivorous fish. This type of fish mainly feeds on plants, such as water plants, filamentous algae, and other plants that grow in the water. Herbivorous fish are represented by grass carp and bream. Grass carp, in particular, is famous for its specialization in eating grass. (2) Carnivorous fish. This type of fish is generally fierce in nature and feeds on other fish. It can even kill animals that are larger than itself. This type of fish generally has teeth. Common fish include catfish, snakehead, and Spanish mackerel. (3) Planktonic fish. This type of fish uses slender and dense gill rakers to filter food. Common food includes cladocerans, copepods, rotifers, and larvae of anarthritic animals. In addition, plankton also includes algae in some aquatic reproductive organisms, such as green algae, yellow algae, flat algae, diatoms, naked algae, and black algae. Common fish species include silver carp and bighead carp. Carp (4) Omnivorous fish. This type of fish has a wide range of food habits. It can eat both animal and plant foods, such as small crustaceans, insect larvae, worms, shellfish, and plant foods such as rice crumbs, bread crumbs, chestnuts, and bean food scraps. Common fish include crucian carp, carp, etc. There are also many other fish, such as some omnivorous fish, bottom-dwelling fish, etc.

9. China’s freshwater predatory fish?

1 sea bass

Perch are usually found at the mouths of freshwater rivers. Occasionally they also forage in freshwater areas. In addition, we sometimes see them in reservoirs. However, they are rare and hard to come by. Perch are ferocious carnivorous fish with a big appetite and a strong desire to feed. They can eat 5%-12% of their body weight, especially in spring and summer. Perch grows quickly and can reach more than one meter in length.

2 Mandarin fish

Mandarin fish usually live at the bottom of the water surface. This kind of fish is very common and is distributed in most waters in China. They like to lie in still water or slow-flowing rivers and lakes, especially in shallow lakes with aquatic plants. This kind of fish has high requirements for the surrounding environment and is more sensitive. During the day, they will lie motionless at the bottom of the water and come out to look for food at night, so this kind of fish is suitable for night fishing. Mandarin fish like to make nests and live alone. When the water temperature is 15-30 degrees Celsius, its activity is still very high. When the water temperature is lower than 7 degrees Celsius, it will no longer be active. It is a typical carnivorous fish because they can prey on the fry of other fish as soon as they hatch. They like to stay in places covered by aquatic plants or blocked by rocks. Anglers can pay more attention to these places when fishing.

3. Upturned lips

The black carp is also a common fish, also known as whitefish or big whitefish. It often feeds in the middle and upper layers of flowing water or wide water areas. This fish is fast and good at jumping. It is more common in rivers and reservoirs and usually feeds on small fish. The largest one I have seen is 10 kg. The sexual maturity age of the black carp is 3 years for females and 2 years for males. The most active period is from June to August. They are used to chasing moths on the water surface. The desire to eat is strongest at night and early morning, so you can choose night fishing.

4. Blackfish

Blackfish is also known as mullet and money fish. It is distributed in all waters except the western region of my country. It is also a target fish that lure fishing prefers. Blackfish generally feed on other fish species, and young blackfish prey on some plankton. After the blackfish bites the hook again, it will burst out with amazing power, and the blackfish is the most aggressive. Generally, it will bite the hook when it sees food. The peak season for blackfish foraging is spring and autumn, and April to July is the spawning season. They will spawn in shallows with lush aquatic plants, and then male and female fish will guard their nests together. Of course, it is not recommended for everyone to go fishing for blackfish at this time. After all, we are "fishing for fishing, not for fish". It is still a bit cruel to spawn and fish for blackfish.

10.What are filter-feeding fish?

Filter-feeding fish are a type of fish that use their gill rakers to filter tiny plankton, bacteria, organic debris, etc. in the water. Representative species include silver carp and bighead carp, which are traditional farmed fish in my country. The most common filter-feeding fish are silver carp (Hypophthalmichthys molitrix) and bighead carp, two of the four major carps.
