Spawning time burbot

Burbot is the only cod among all freshwater fish species. It inhabits practically the entire territory of Russia, with the exception of the waters of the Caucasus and Kamchatka. The appearance of the burbot and the way of life that he leads is proof that this fish is relict. She inherited the cold-loving from her ancestors, who lived even in the ice age.

Most often burbot is found in water bodies in the northern hemisphere. This fish is especially common in Siberian rivers. Burbot is considered a valuable commercial breed. Liver burbot - a real delicacy, rich in fats and vitamin A.

In appearance, this representative cod something like a catfish. He has a very wide, very flat head, almost like a frog. Eyes burbot small, small mustache on chin. Fish maw is wide, with a large number of small teeth.

Color burbot primarily depends on the quality of water. Usually the back and fins are greyish or olive-green, covered with black-brown stripes and spots.The belly and pelvic fins are almost always whitish.

In the waters of our country there are two types of this fish: marble and black. Ichthyologists believe that the younger the burbot age, the darker it is, and only over the years the fish brighten.

For successful fishing for burbot, one interesting feature of this specimen should be taken into account: we are talking about the susceptibility of prey to different sounds. Burbot is not only not frightened by the noise or the human voice, but also goes to them.


In the population, the number of males of this representative cod is significantly greater than the number of females, usually two or three times. Burbot reaches sexual maturity by the third year of life. The males start something like estrus, they pair in pairs with the female and fertilize the eggs. Mature caviar can even be in fairly small individuals.

Practically in all reservoirs two species live simultaneously - large and small, and the latter are painted almost black. The lake species of this fish grows faster than the river. They spawn only after reaching a length of 30-35 cm and a weight of about 1.5 kg. Juveniles burbot grows up very quickly, almost the same as the young of another predator - pike.In places where there is favorable conditions for normal life, by June the fry hatching from caviar in winter reach in size from 7 to 9 cm in length. Until the age of one year, the little nalimchiki hide in stones and only by the summer of the next year they go to a greater depth to silt places. This fish becomes predatory only after reaching puberty.

Spawning period

River burbar likes to attack small perch, gobies, ruffs and minnows, which with the onset of the first cold weather descend to the channel part of the reservoir, occupying the upper borders of brooks and dumps. With the beginning of winter, the pre-spawning migration of burbot begins. The fish, leaving their pits and koryazhnikov, gradually rises upstream. It moves to medium and shallow depths, to areas where pebble, stone or solid sandy structure of the bottom soil prevails.

Ikrometu this freshwater representative of cod is preceded by a very long pre-spawning zhor. It lasts almost all autumn and a few days in early December. During this period, the water begins to cool gradually. Predator, awakening from summer hibernation, switches to active nutrition.The main objects of fish feed during this period are small bottom fish, invertebrates, remains of underwater inhabitants and crustaceans.

The time when the burb is spawning

The largest populations of this freshwater representative of cod are found in the northern latitudes of our country. Here, this fish lives in almost all waters. Large individuals feel great in fast cold rivers. The spawning time of burbot falls around mid-winter, usually in January. For example, the spawning of burbot in the Urals is traversed at the most deaf. It must be said that in this region, it was during this period that fishermen caught valuable commercial fish by drilling holes in the middle of the river.

Spawning burbot in Siberia, for example, can begin in the second half of December. Often in the waters of the central part of our country, it shifts to February. The timing of spawning of burbot depends primarily on the region of the fish habitat, on a particular lake or river.

How is spawning burbot

Spawning of this representative cod is accompanied by active feeding. The first to go to spawning sites are experienced large specimens, gathering in small groups, as a rule, not more than twenty fish.

Then begins spawning burbot, which has an average size.The latest to the spawning are young fish that gather in flocks up to hundreds of specimens. Experts believe that they always move along the same route. Up stream, the burbot go slowly, mostly at night. To the non-breeding grounds, their paths pass along stony areas or gravelly bottom at a relatively shallow depth. Shallow places with solid bottom soil are the most optimal conditions for spawning. Burbot during the spawning period can often be found in areas with a rocky bottom covered with pebbles or a shell on a sandy, hard, cartilaginous relief.

Conditions for spawning

The flow on the spawning ground should be slow, so that the fish do not have to expend a lot of effort to fight the water flow. The first individuals to spawn are large individuals, then younger specimens.

The females of this representative of predatory cod are very prolific. One fish can sweep in the amount of about half a million eggs. Naturally, not all of them hatch fry, besides not all the young survive. Many of the offspring are destined to become food for underwater creatures, for example, perch, ruff, bull, busters, etc.Since spawning of burbot falls on the winter period, in some regions of Russia, where its limited populations are observed, the catch ban is in effect at this time.

Breeding features

Eggs of burbot have yellowish color. They are relatively small - from 0.8 to 1 mm in diameter, but very numerous. Therefore burbot, which spawns during the winter period, is considered one of the most prolific fish. Despite the fact that small individuals throw up to two hundred thousand, and large ones - up to half a million and even more eggs, the populations of this representative cod are very small. This is due to the fact that only a small part of the offspring develops into juveniles. The overwhelming majority of the fish hatched from the eggs either become prey for other fish, or die at all due to unfavorable conditions for life.

After spawning

Burbot spawns in the river, almost always in sandy shallow or cartilaginous areas with fairly moderate currents. Females literally "pour out" the liquid mass in the space between the stones or in the pits. At the same time, a significant part of the eggs is carried away by the water even before they manage to stick to the bottom ground.A considerable part of them becomes prey of other underwater inhabitants. Both young and adult females, which have already laid eggs or even just gathering for spawning, eat their future offspring, which in large quantities lies at the bottom and makes up easily harvested feed material. In addition, minnows, perches and ruffles during the period when the burbot spawns, leave their stands and, having eaten plenty of eggs, go back again.
