Trout fry release into Lake Sevan is insufficient to restore the trout
population, Bardukh Gbrielyan, Director of the Scientific-Research
Center of Zoology and Hydroecology, National Academy of Science of
Armenia, told media, Monday.
The expert said that mature adults are almost deprived of an
opportunity to spawn in the rivers falling into Sevan.
"To restore the population of trout a package approach is required.
First of all, it is necessary to improve state of the rivers where
the fish is spawning," he said.
He alarmed of the situation in the Karchaghbyur River. "There is
no longer river bed there, so the fish cannot spawn," he said. In
addition, part of the river waters run through HPP, while the turbines
are dangerous for the fish.
Another problem is the Rainbow Trout private ponds for which water is
released from Karchaghbyur River. Gabrielyan said that the given wild
trout may be dangerous for the Sevan endemic fish. Rainbow Trout from
the private ponds often occur in the lake due to heavy rains. There
is another headache - poachers. So, it is becoming senseless spending
state funds on production and release of fry into the lake, because
mature adults are often poached, he said.
In 2012 166.000 Gegharkuni fry and 200,000 Summer Trout fry have been
released into Sevan. The total cost of the project is 59.5 mln drams.
