Cyanobacteria (blue-green algae) have been observed in Lake Sanaa, and the initial stages of the lake's blooming have already begun, as RA Deputy Environment Minister Irina Ghaplanyan said at the press conference held on June 2. She mentioned three main reasons for the lake blooming: lowering the level of the lake, accumulation of organic matter in the lake and global warming.
"We are actually entering the stage of lake waterlogging, which is dangerous."If we can't prevent the influx of organic matter into the lake, we can actually lose the lake," she said.
Irina Ghaplanan emphasized that the Armenian government has made a decision on the order of industrial hunting in Lake Sevan. According to the draft, industrial fishing for no less than 500 grams of whitefish will be allowed within 200 tons, and fishing for the carp will be unlimited.
