Tench: description of fish, lifestyle, catching, breeding and growing fish
Ling is a carp fish, a traditional inhabitant of rivers and lakes. It is believed that the fish got its name because of the conditional link. The tear covering his body dries up on the ladder where he was caught. According to another version, the name of the fish came from the verb, that is, from the adhesion of the same mucus.

European water bodies can be considered as a homeland. From Europe, fish spread across Siberian rivers and lakes to Lake Baikal. It has been found in parts in the Caucasus and Central Asia. Lina often tried to move. He was introduced to reservoirs in North Africa, India and Australia.
Description and features
The personality of this fish begins with the appearance of the line. Its shell does not cast silver and steel, but resembles green copper. Dark top, light sides and even lighter abdomen. The color range, from green to bronze, black and olive, depends on the living conditions.
The unusually colored body is complemented by small red eyes. Round fins and thick mouth enhance the feeling of the physical body of this line. Small hooks, typical of some carp species, hang from the corners of the mouth.
A notable feature of the line is the large amount of mucus, which is separated by numerous, minimal glands under the scales.
As the fishermen say, the penis depicted in the picture leaks because of this mucus. Tear – the secret of viscosity – covers the body of almost all fish. Some have more, some have less.
Phosphorus is the champion among carps in the amount of surface mucus.
Phosphorus is found in poorly oxygenated areas, but it is rich in parasites and pathogenic bacteria. The body responds to threats from the environment by secreting mucus – glycoproteins. Otherwise, these compounds are now called mutations. These protein molecular compounds play an important protective role.
In its consistency, the mucus resembles a gel. It can flow as a liquid, but as a solid it can withstand certain loads. This allows it to resist the teeth of predatory fish, as well as parasites, which allows to avoid injuries.
Mucus has healing properties and is a natural antibiotic. Fishermen rub wounded fish, even pike, with a stick to heal the pain. However, these stories are mostly related to fishing bikes. There is no reliable evidence of such stories.
Low mobility, short-term spikes in food activity, without reducing the quality of water and the amount of dissolved oxygen in it, healing mucus is an element of the survival strategy. Such strong arguments in the struggle for life did not make phosphorus a very common fish, inferior in the collection of crows.
In terms of biological phylogenesis, phosphorus is closest to cardinal fish. It consists of one subfamily, Tincinae. Scientific name of the genus: Tannishsis. These small groups are well known to aquarists. At first glance, the relationship is not obvious.
However, scientists claim that the morphology and anatomy of these fish are very similar. Delay can be seen as a successful product of evolution. This has been confirmed by biologists who believe that the lineage (system name: Tinka Tinka) consists of one species of Tinka Tinka and is not divided into subspecies.
Rare cases when a common fish in a vast area is not subjected to serious natural modifications and there are no several species in its family. The same species can take different forms. Such divisions are more subjective than scientific. However, in fisheries there are three forms of line.
They differ in size – fish living in ponds are the smallest. And the ability to live in water due to lack of oxygen – river lines are the most demanding. In addition, new forms of lines appear due to their popularity among owners of private and decorative reservoirs.
Farmers, fishing for such purposes, make ladders of different colors, changing the external type of fish. As a result, thanks to the achievements of science, a line of forms created by man has appeared.
Lifestyle and habitat
Phosphorus is a freshwater fish. It does not tolerate even slightly salty water. She doesn’t like fast rivers with cold water. Lakes, ponds, river plants, grown cane – favorite habitats, muddy biotopes. Phosphorus loves warm water. Temperatures above 20°C are particularly pleasant. Therefore, it rarely goes deep and prefers smaller water.
Staying among aquatic vegetation with rare access to clean water is the main style of landscape behavior. The morning feeding hours can be considered as a period when fish are somewhat more active. The rest of the time, they prefer to walk slowly, sometimes in pairs or small groups. There is a suggestion that the name of this fish lies in laziness.
Manual fishing in small bodies of water has taught fish special behavior in the winter period. With the onset of frosts, lianas dig holes in the mud. The metabolism in your body is minimized. There is a condition similar to hibernation (hibernation). Thus, when the pond freezes to the bottom and the rest of the fish die, the lines survive the harshest winters.
Nutrition
The habitat of the line is rich in dithrite. These are dead organic microscopic animal particles in the final stages of decomposition. In larvae, the main type of nutrition is retardation.
The line, which develops into a stage, adds small free-floating animals, t. Yes. zooplankton. A little later the line reaches the bottom, or the top layer of the substrate, t. Yes. living organisms living in the upper layer of zoobentus.
With age, the proportion of zoobentosis increases. From the layer of boots, the fly selects the larvae of insects, small leeches and other cautious inhabitants of the water. The importance of detritus in the diet of the elephant decreases, but aquatic plants appear in the diet and the proportion of shellfish increases.
Adult fish, like a young pair, give mixed food. Small bottom inhabitants, mosquito larvae and shellfish are present in both aquatic vegetation and the line diet. The ratio of protein to green food is about 3:1, but can vary significantly depending on the body of water in which the line population lives.
Phosphorus shows food activity in the warm season. Food interest increases after spawning. During the day, the lint feeds unevenly and is devoted to it mostly in the morning. He approaches food carefully and shows no signs of hungry greed.
Reproduction and life span
In May, with the warming of the water, the line begins to take care of its offspring. Before spawning, deposits are discarded. Lin ceases to be interested in extra food and burial. From there, they leave in two or three days and go to the breeding site.
During spawning, the lint does not change its habits and finds other favorite habitats. These are quiet, shallow plants with enough aquatic vegetation. Grass is especially respected
