Can golden carp live without almost all scales?

The scales of golden crucian carp are almost gone, and they can't live.

Carp, commonly known as carp muscle development, hairy seeds and so on. , belonging to CYPRINIDAE. The body is flat and round, the mouth is horseshoe-shaped, and it must be 2 pairs. The base of dorsal fin is long, and both dorsal fin and gluteal fin have thick spines with serrations. The side is golden yellow, and the lower leaf of caudal fin is orange red. Carp usually inhabit the bottom of rivers, lakes, reservoirs, ponds and other water bodies with aquatic plants, and mainly feed on benthos.

Strong adaptability, cold resistance, alkali resistance and hypoxia resistance. They can lay eggs in running water or still water, and their spawning places are mostly in aquatic plants, and their eggs are attached to aquatic plants for development. Carp is one of the freshwater fishes with the largest species, the widest distribution, the longest culture history and the highest yield.

A thick green-brown fish of CYPRINIDAE (CYPRINIDAE), whose scientific name is carp. Originally from Asia, it was introduced to Europe, North America and other regions. They have huge scales and two beards on each side of the upper palate. They live alone or in groups in ponds, lakes and rivers, and their bottoms are calm and covered with grass. Omnivorous, digging food often makes water turbid and increases turbidity, which has adverse effects on many animals and plants. Therefore, carp is often regarded as unwelcome, and it takes great efforts to get rid of it. Because Europeans and Americans don't eat stinging carp, and carp has no natural enemies in North America and Europe, it was once flooded and was regarded as a harmful species, which is also closely related to the eating habits of Europeans and Americans.

In winter, carp hibernate and sink to the bottom of the river without eating anything. In spring, female fish often lay a large number of eggs on plants or sundries in shallow water, and the fertilized eggs hatch after 3~4 days. Carp grows rapidly, reaches sexual maturity in the third year or so, and can survive for more than 40 years under feeding conditions. The average length is about 35 cm (14 inch), but it can exceed 100 cm (40 inch) and weigh more than 22 kg (49 pounds). Carp is often cultivated for food, especially in Europe and Asia, and a large number of fish can be produced per mu of water. Mirror carp (with several large scales) and leather carp (almost without scales), two kinds of carp, are both domestic varieties. Carassius carassius is an unnecessary European relative of carp.

Carp is a temperate freshwater fish native to Asia. I like to live in a warm lake or a slow-flowing river on the plain. Distributed all over the world except Australia and South America. It has been used as ornamental fish or edible fish in China and Japan for a long time, and it has also been cultivated as edible fish in Germany and other European countries. The dorsal fin root is long, without fat fins, and the mouth usually has whiskers, but some don't. There are throat teeth deep in the mouth, which are used to grind food. There are many kinds of carp, about 2900 species.

Carp is a benthic omnivorous fish that eats both meat and vegetables. The bait spectrum is wide, the snout bone is developed, and it often feeds on mud. Carp is also a low-temperature animal, and its body temperature changes with the change of water temperature, so it does not need to consume energy to maintain a constant body temperature, so the total amount of bait intake is not large. At the same time, carp, like most freshwater fish, belongs to a kind of fish without stomach, with short intestine and fast metabolism, so its feeding habit is to eat less and eat more. The digestive function of carp is closely related to the water temperature, and its feeding is seasonal.

Winter (especially under the ice) is basically in a semi-dormant state, and body fat is exhausted in winter. Spring is coming, and it is eager to eat high-protein food to supplement it. As late autumn and winter approach, in order to hoard fat, there will also be a peak period of "grasping food", and it is also based on high-protein bait. So early spring. Fishing carp in late autumn should be mainly based on animal bait such as earthworm and river shrimp.

After the spring, with the increase of temperature, the fish's food intake increased, and the quality of bait was not important, and the number rose to the first place. So in late spring, all summer and early autumn, carp are mainly vegetarian. At this time, you should use surface bait and bad food when fishing.

Although carp is a benthic fish, it does not mean that its active area remains unchanged. Seasonal changes, water temperature changes. Changes in wind direction, air pressure, horizon, water quality, water flow, water level fluctuation, dissolved oxygen in water, prey environment, etc. , will change the activity area of fish at any time, so that they are often active to a large extent. If they are in a large area of water, this is called "migration". Compared with other freshwater fish, carp has the same habits and special habits. These habits are mainly determined by the needs of reproduction, feeding and aerobic survival.
