1. 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.

2. 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.

3. What does filter-feeding fish mean?

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 types of filter-feeding fish are silver carp and bighead carp, two of the four major carps.

Filter-feeding fish, also known as fat-water fish, feed on plankton and organic debris in the water by filtering them. They have specialized filter-feeding organs, mainly composed of gill rakers, gill raker tubes (branchial organs), palatine folds, and gill arc bones.

4. 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.

5. Can filter-feeding fish eat Microcystis and Anabaena?

Microcystis and Anabaena are some common cyanobacteria. They will reproduce in large numbers in some natural waters and may produce some toxic metabolites, which may cause some harm to aquatic organisms and human health. Therefore, in general, it is recommended not to let filter-feeding fish (such as carp, black carp, etc.) eat aquatic products that may be contaminated by Microcystis or Anabaena.

For these cyanobacteria, their main toxic components are microcystins and anabaena toxins. Different cyanobacteria will produce different types and amounts of toxins, which can have different degrees of toxic effects on various organisms. Some filter-feeding fish may be able to eat some contaminated algae or other toxic organisms in moderation, but if they eat too much algae or other toxic organisms, it may be toxic to the fish and eventually be excreted or die.

Therefore, in general, we recommend that filter-feeding fish not eat aquatic products contaminated by Microcystis or Anabaena to avoid potential food safety issues. If you are unsure whether a certain fish is safe to eat, it is recommended to consult relevant professionals or local fishery production management departments.

6. Freshwater filter feeder?

Filter feeders filter food from the surrounding marine environment. This method of feeding is very efficient and is used by animals living in freshwater and oceans. The largest animal known to use this method of feeding is the blue whale, whose prey is mainly thumb-sized crustaceans - krill.

Filter feeders also include birds, fish, and worms, as well as many other invertebrates, from clams and barnacles on seashore rocks to jellyfish-like ascidians in the sea.

7. Filter-feeding organisms in fish tanks?

River mussels, freshwater snails, silver carp

River clams are filter-feeding mollusks that survive by filtering organic matter from the mud in the water. If you want to keep river clams alive artificially, you cannot turn on the filter water pump, but you can add oxygen.

Silver carp likes fertile water. It is a filter-feeding fish and likes to eat floating algae and plankton, which are absolutely lacking in the fish tank.

Freshwater snails have a wide range of diets, mainly consisting of microorganisms in the water, fish feces, and diatoms.

8. Filter-feeding freshwater animals?

Filter feeders are animals that feed on plankton in the water by filtering; they include active filter feeders and passive filter feeders.

Foreign name: filter feeders

Definition of filter-feeding animals

Types Active filter feeders and passive filter feeders

Represents flamingos, blue whales, etc.

Filter feeders filter food from the seawater around them. This method of feeding is very efficient and is used by animals living in freshwater and the ocean. The largest animal known to use this method is the blue whale, whose prey is mainly thumb-sized crustaceans called krill. Filter feeders also include birds, fish, and worms, as well as many other invertebrates, from clams and barnacles on seashore rocks to jellyfish-like sea squirts in the sea.

9. 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.

10.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.
