Yenisei sturgeon – the age of dinosaurs
In full-flowing Siberian river began a new life the young sturgeon and grayling. These types of fish are in desperate need of Yenisei. They were grown on the farm until of age, when it may exist in nature on their own.
Kids 5-6 years, which carefully bear in the palm of transparent cups with small fish and, barely breathing, release fry into the Yenisei, is a very touching sight. It is unlikely that the boys and girls who participated in environmental action in the future will deliberately harm the river and its inhabitants. So it lays the Foundation of careful attitude to nature. Children invited from the kindergarten No. 317. They were joined by children of employees of SGC. Organized and conducted a campaign the staff of the Krasnoyarsk TPP-2.
First 1200 fingerlings, which experts raised about two months, was brought ashore in a large tub. The children looked interestedly at the tiny fish, to the fate which they will touch, choosing their favorites. The outlines of small fish are similar to adult individuals is an important brisk sturgeon and grayling. Then each child was given into the hands of transparent glass, where it splashed a few fry. At a time, under adult supervision, the boys approached the edge of the platform and released “fish children” in great river and a great life. Each managed more than once to come back for a new Cup with fish.
The best time and place
No less important aspect of environmental action is the replenishment of the fish resources of the Yenisei. Fry released in the island area and a utility bridge. The place was not chosen accidentally – the environment here is the most suitable for restocking.
“Place of issue recommended by the research Institute – it is protected from predators, a rich food for fry growth. Time is also carefully chosen – in August the fish quickly adapt to their natural environment. Unfortunately, the human impact on water bodies now is that of natural replenishment is not enough. Such actions in the future will become traditional, annual”, – said the Director of Krasnoyarsk CHP-2 SGK Oleg Bubnov.
The fry should join the migratory flow of fish, which takes place in this area. Sturgeon is now considered a protected species and fish included in the Red book. Because of the valuable caviar and meat, he undergoes a massive catch, and poaching. Grayling fishing is also fish. In Krasnoyarsk region it fished very actively, so the resource needs constant replenishment.
“We hope that the released fish will go into the lower reaches of the Yenisei river, where it will be regulatsia, and to spawn back here. In General, artificial reproduction is compensation for the harm that is caused by humans to the environment. It’s not just the action, but important function. Well, today it involves children, it fosters in them a responsible attitude to water resources”, – said the Deputy head of the Yenisei territorial administration of Federal Agency for fishery Olga Kochergina.
Salvation Abakan ducts
In the Gulf prior to release of fingerlings activists of Krasnoyarsk CHP-2 and Green squads spent a few Saturdays. Territory cleared of the debris that was left by unscrupulous fishermen and vacationers Krasnoyarsk. Release of fingerlings and the elevation of the shore is not the only environmental activities that are carried out
Demonstrate familiar with the deplorable state of the Abakanskaya ducts. In fact, she’s dying – spread algae blooms, water. This happened after the construction of dam for construction of a residential complex. Cold streams, which swell the river, ceased to exist, the result is stagnation.
Everyone understands that the canal should be saved, and the company Siberian generating company has assumed the financial obligation for the development project to clean ducts Abakan. The work should be completed before the end of 2018, and after the document is sent for approval to the Ministry of ecology and natural resources of the Krasnoyarsk territory and the state examination.
Experts have already started work to calculate which method and how to carry out the cleaning of mud, is the measurement of depths, bottom sediments. Determined the mechanism by which will keep clean of algae. It is planned to clean the canal for Communal bridge to the Yaryginsky move.
“First task is to develop the project and to understand what they need to do to flow alive. The terms of reference were made very carefully, tried not to forget anything. The work started at the end of 2017, now has already signed a contract,” – said Oleg Bubnov.
The messenger of antiquity
Sturgeon appeared about 200 million years ago. Millions of years these slow and majestic fish migrated along the rivers, while around them changing era, the fauna, the climate and even the planet itself. Having survived all cataclysms of the earth, today, the sturgeon lives only in the Northern hemisphere, including the rivers of the Yenisei basin. However, in our time, there is serious danger of the destruction of the oldest inhabitant of the Siberian rivers.
Yenisei sturgeon lives about 60 years old, can reach three meters and weight of 80-100 kg. Production has acquired an industrial scale in the 19th century. Then from the Yenisey caught to 400 tons annually.
The highest mortality of fish at the stage of development from eggs to larvae. In the nature of 100 thousand eggs in sturgeon fingerlings develop only two. Artificial breeding allows you to obtain and release into the river 25% juveniles.
