Vobla - a fish from the carp family, is a subspecies of roach. This type of fish has commercial value, and also acts as an object of amateur and sport fishing.
It differs from river roach in somewhat larger sizes up to 30 and more centimeters. As well as the color of the eyes: in the wobble, they are silvery with darker spots over the pupils. The mouth is at the end of the muzzle. The roach has a rather large scale.
The back is almost black, casting blue or green. The sides and belly are silver.
SpreadVobla (Rutilus caspicus).
Vobla is found in the Caspian Sea basin. Three main herds are distinguished: fish - Turkmen - in the south-east of the Caspian Sea, Azerbaijan - in the south and south-west, and the North Caspian herd, as the name implies, lives in the northern sea.
FoodVobla is a fish that is loved all over the world.
Vobla eats animal food, in its diet - various sedentary invertebrate organisms living in water bodies.
During its life, vobla breeds about five to six times. Fish spawn in April-May to a depth of about 50 centimeters. Hatched fry immediately go to the Caspian Sea.
Life cycle and developmentThroughout its life, vobla breeds about five to six times.
In winter, the fish lives in the sea, in the so-called wintering pits near the mouth of the Volga. She is half asleep and does not eat at this time. At the beginning of spring, the roach goes to the rivers, and in cold weather its course is delayed, but the wind blowing from the sea, on the contrary, accelerates movement. In schools schools begin to gather at the end of February.
The most peak moments, that is, when the course is especially numerous, occur in April, when the rivers completely get rid of the ice. In search of places for spawning, huge schools of roach go to all tributaries of the Volga. Basically, it goes at a depth, but with a strong current it goes along the coast. A lot of fish going to spawn die.The size of the roach.
The fish ceases to eat even before it spawns. At this time, she lives off the accumulated fat, and only mucus is in the stomach. After the fish has laid eggs, it becomes so skinny that the head seems unnaturally huge on a skinny, puny body.
During spawning, the roach, as well as the females and males, have the so-called “mating” outfit. , On the skin scales of mature fish, warts with a sharp white top are formed, which darken after a while. Part of the head is covered with whitish growths. The external integument emits a lot of mucus, which covers with a thick layer the whole body.Dried roach is a real delicacy.
After spawning, the roach begins to eat intensely, making up for the weight loss of the "hungry" period. At this time, she goes back to sea, only in smaller schools - the fish returning after spawning is called "downstream". Fish are prepared "thoroughly" for wintering - they eat their well-fed sides, become fat. The whole body of the roach is covered with a layer of mucus, which saves it from hypothermia.
Vobla is a desirable food for predators; seals and beluga (a species of sturgeon) feed on it.
