📖 Overview

Found along near shore of Lake Doiran. Spawns in surf zone of the lake. Pumping of water in the lake for irrigation has lowered its water level by at least 4 m since 1990 and has caused in the disappearance of subaquatic vegetation, leading to a severe ecological stress throughout the lake. If pumping continues at its present rate, there is a risk that the lake will run dry . .
