Offsprings of the kutums, freshwater fish, appeared for the first time it the centre of oceanography and marine biology "Moskvarium" of the VDNKh. This is a great event for the Moscow ichthyologists — the kutums are included in the International Red Book and the Red Book of Russia and are on the verge of extinction. It is not easy to get and breed the offspring of these fish: they need special living conditions and tireless care. Users of social media have a unique opportunity to observe together with specialists the development of the hatchlings: photos and videos about the life of growing kutums will be regularly published on the Moskvarium’s Instagram, Facebook and VKontakte

Kutums are freshwater actinopterygians of the carp family. They got their name for their powerful teeth that easily bite through the shells of mollusks. Another characteristic feature of these aquatic inhabitants is the beautiful pearl color that they acquire during the spawning period.

Fish of this species can be found in water bodies in the south of Russia, as well as in Azerbaijan, Iran and Kazakhstan. However, they are getting fewer in the wild. Their population is rapidly declining due to its special sensitivity to the purity of water and because of the poaching. Therefore, ichthyologists around the world take special measures to preserve and reproduce the kutums.

They live in the VDNKh’s Oceanarium since it opened in 2015. Moskvarium takes part in programs for preserving and reproducing rare species of animals, and the kutums breeding is part of the job. Now ichthyologists managed to get five small fish.

A special "kindergarten" was arranged for them, where they are not threatened by predators and optimal conditions for growing up are created. While the length of the small fish is only three to five centimeters, however, an adult species can be as long as 75 centimeters. Ichthyologists regularly examine the hatchlings, measure their weight and length, and monitor their diet and water composition. Small fish mainly eat plankton.

It is planned to relocate the growing fishes to their relatives next year. Adult kutums live permanently in aquarium No. 3 "Freshwater Predators" at the beginning of the exposition. Five representatives of this species live here: three females and two males. All of them have reached puberty; they are seven years old.

VDNKh’s Moskvarium opened in August 2015. This is one of the largest oceanariums in Europe, with more than 12 thousand animals from all over the world permanently living in it. There is also a wide exposition that unites inhabitants of the Russian rivers and seas: from the Russian sturgeon and the White Sea lumpsuckers to the octopus and Amur sea stars that inhabit the Far East. In October 2021, a new aquarium dedicated to the inhabitants of the Moskva River was opened in the Moskvarium.
