Common freshwater fish names and pictures 2 There are many kinds of freshwater fish, among which the common ones are carp, crucian carp, grass carp, Qingjiang fish, catfish, herring, silver carp, freshwater bass, eel, etc. Besides, there are many kinds of freshwater fish. At present, there are more than 8,600 species of freshwater fish known in the world, and the fish we usually use as ornamental also belong to freshwater fish, including many tropical fish, which also belong to freshwater fish.

Freshwater fish: in a broad sense, it refers to fish that can live in fresh water with salinity of three thousandths. In a narrow sense, it refers to fish that have to spend their whole lives in fresh water in some stages of their life history, such as juvenile or adult fish.

Most freshwater fish have special colors and stripes, or the body color is consistent with the surrounding environment, which can hide themselves, or confuse enemies and prey to protect themselves or sneak attack on prey. In shallow water, the body color of fish is usually blue and green, and the belly is light white. These colors are called extinction colors. When you look up at the bottom of the water, you think it is the sky; when you look down, you think it is seawater; while in deep water, the body color is very gloomy, often dark red and black. Freshwater fish is a kind of fish that likes to swim in teams on the surface of the water.

Freshwater fish often live in aquatic plants and rivers, and the fish's stripes are mostly dark black stripes, which have the function of protecting color. Most of the fish that are active at night are either gray or black, and a few are red.

Freshwater fish are mostly herbivorous and omnivorous, but there are also a few carnivores. Upper reaches of rivers: they mainly feed on insects and attached algae. Downstream of rivers: they often feed on plankton and organic debris.

Basically, as long as there is fresh water, there are freshwater fish living in it, and traces of freshwater fish can be found from warm and pleasant hot springs to the north and south poles frozen into the heart and lungs.

Freshwater fish is easy to move horizontally, with excellent motive power, which is convenient for hunting food and avoiding predators.

Freshwater fish farming:

If you want to achieve the goal of stable and high yield, you should put in enough fish species. In general, the production of freshwater fish is about four times as much as that put in.

The water for breeding freshwater fish must be pollution-free, and when the oxygen content is lower than the standard value, the oxygen should be increased in time to strive for greater output in the limited waters.

The quality of feed determines whether the meat quality of adult fish is delicious, so we must ensure the quality of feed, never use moldy and deteriorated feed, and we must not ignore the proportion of feed components.
