ABNORMALITIES IN THE WEDGE SOLE Dicologlossa cuneata (MOREAU, 1881) AND BLACK SEA TURBOT Scophthalmus maeoticus (PALLAS, 1814) FROM TURKISH SEAS

Abstract

Both color and morphological abnormalities on two different flatfish species [Dicologlossa cuneata (Moreau, 1881) and Scophthalmus maeoticus (Pallas, 1814)] have been recorded from Turkish seas. Abnormal flatfish species, Dicologlossa cuneata (Moreau, 1881), wedge sole, was sampled from two different localities in Aegean sea. First wedge sole from Izmir bay (Aegean sea) had three different colour abnormalities (ambicoloration; albinism and xanthochroism) on eyed and blind sides of their body. Other abnormal wedge sole specimen from Ekincik cove (Aegean sea) had ambicoloration on blind side of the body. Second abnormal flatfish species Scophthalmus maeoticus (Pallas, 1814), Black sea turbot, was caught from the Black sea coast of Istanbul and the specimen had totally ambicolored (blind side of the body was colored as like as eyed side) and morphological abnormalities (a fleshy piece-hook-above the head).
