Seasonal distribution and migration pattern of the turbot (Psetta maxima Linnaeus, 1758) in the eastern Black Sea, Republic of Turkey
Öz
In order to determine the seasonal distribution and migration
pattern of the Black Sea turbot, Psetta
maxima (Linnaeus, 1758) specimens were collected off
Trabzon, Turkey, in the eastern Black Sea. A total of 422 specimens were caught
by 364 otter trawl hauls in 95 cruises from 24 July 1997 to 19 February 1999.
Average catch per unit effort per thirty minutes by the otter trawls with the mouth
opening of 15 m was 1.2 individuals. Turbots were distributed between 5 m and 70 m depth, where bottom
water temperatures varied from 26.4℃ to 8.0℃. They were found mainly at 10 m in July - October and at 5 - 60 m
in November - March. However, the turbot were found in high densities at <
20 m depth from April to June. Therefore, it appears that Black Sea turbot
migrates from deeper water to shallow coastal waters during the spawning season
of April to June. Off Trabzon, P. maxima spawns
in coastal areas < 20 m deep.
