Burbot fish: description, habitat, size

The only freshwater species from the cod family is burbot fish. This is a predator, leading an active nocturnal lifestyle.

It can be found in clean cold lakes and rivers with a rocky bottom. This fish is a relative of Atlantic herring, and therefore has many of its habits.

It is very popular with anglers and has a high value.

The burbot fish is the only freshwater representative in the cod family.

The level of fish distribution is closely related to its inability to stay long in stagnant and excessively warm water. The largest number of livestock can be found in the northern part of the hemisphere, for example, in Siberia and in the basin of the Arctic Ocean, as well as in the North-East and North-West of Russia.

And yet the fish lives in the southern regions, but this is a very small livestock. In rivers that flow into the Caspian and Black Sea, the average weight of individuals is not more than 0.7 – 1.0 kg.

Even in the cold lakes in the North, this fish will still look for the coolest place. She loves underwater keys, and in extreme cases she chooses pits, snags and all sorts of stone piles.

The composition of the bottom does not represent a special meaning, it can be clay, sand, pebbles, etc. The only exception is a large amount of silt.

Predator poorly oriented in muddy water, therefore, in such areas will not climb.

In order to understand how a fish looks like burbot and to identify it as accurately as possible, the easiest way is to compare an individual with catfish. They are very similar and beginner anglers often confuse these two species. The main differences are as follows:

  1. All cod on the chin, only one mustache. And in the region of the upper jaw the mustache is much smaller than the catfish.
  2. Som has a large size. His head is very impressive and powerful in contrast to the flattened burbot.
  3. Som does not have randomly scattered spots throughout the body and its color is darker.

In addition to the differences in appearance, these two predators have different habits. Burbot is most active during the cold period of the year, unlike catfish, whose activity is more productive in May-July.

Spawning of the codfish occurs in winter, and in catfish it happens at the end of May.

The average weight of burbot reaches 3-6 kg.

The average size of the burbot: weight 3−6 kg and a length of 60−80 cm The record holder was 120 cm long and weighed 25 kg.

Age, water quality, habitat conditions and the type of bottom affect how a burbum looks. Olive belly, black-gray fins and dark sides are most common.

With the onset of old age color fades.

The predator is active only at night. His senses are designed to hunt in the dark.

The light of the sun irritates the eyes of the inhabitants of the depths, because he spends the whole day in his refuge (in a hole or under stones).

The same behavior of fish manifests itself with a significant increase in water temperature, which causes her lack of appetite and apathy. In cloudy and cool weather, he becomes voracious and active.

Another interesting predator habits – observation in relation to sounds. Burbot has excellent hearing and is curious, trying to find sources of noise.
