Despite some signs of recovery of BST local population during 2009-2010, analysis revealed numerous signs of absence of stability in the local turbot population: low sizes of spawners in comparison with other Black Sea areas, permanent inverse sex ratio, high level of pigmentation abnormalities coming from early development and high level of diseased adult individuals which reflect fishery effects and unfavorable environmental conditions.
