The State-of-Art of the Black Sea Turbot Spawning Population off Crimea (1998-2010)

Long-term study (1998-2010) of the Black Sea turbot spawning population in Sevastopol region (Crimean coast, Ukrainian sector of the Black Sea) was carried out on the basis of monitoring of the turbot gill net catches. 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.
