1 NSTTUT ZA OCEANOGRAFJU RBARSTVO - SPLT HRVATSKA SSN No. 83 BLJES~E - v J NOTES 2000 The First Record of Megrim, Lepidorhombus whiffiagonis (w ALBAUM, 1792) in skenderun Bay (Northeast Mediterranean Sea) Nuri BA$USTA\ ihsan AKYURT1,AsiyeGiRGiN2 lthe University of Mustafa Kemal, Facu1tyof Fisheries, PK 23, skenderun,turkey 2TheUniversity of Firat, Faculty of Fisheries, Elazig, Turkey Lepidorhombus whiffiagonis (WALBAUM,1792) has been officially recorded for the firsi time in skenderun Bay (36 50'N; 36 00'E). This finding strongly declares that L. whiffiagonis is present in the Turkish territorial waters of the Mediterranean Sea. Key words: Lepidorhombus whiffiagonis, megrim, skenderum Bay, first record '\.t( NTRODUCTON Megrim, Lepidorhombus whiffiagonis (WALBAUM,1792), belongs to the family of Scophthalmidae. This family consists of 5 genus: Lepidorhombus, Phrynorhombus, Psetta, Scophthalmus, Zeugopterus"with 18 species (NELSON, 1994). L. whiffiagonis is widely distributed species found in Atlantic coasts from 64 N (including celand) to 26 N (Cape Bojador) (NELSEN, 1986), and in the Mediterranean Sea, from the southern shores of Spain to the Eastern Aegean Sea (NELSEN, 1986;..

JARDAS, 1996), shores of Greece (PAPACONSTANTNOU, 1988), Western shores of Egypt (BAUCHOT, 1987), Morocco, Tunisia (BAUCHOT, 1987), Algeria (BAUCHOT, 1987; DJABAL et al.,1993).

2 JARDAS, 1996), shores of Greece (PAPACONSTANTNOU, 1988), Western shores of Egypt (BAUCHOT, 1987), Morocco, Tunisia (BAUCHOT, 1987), Algeria (BAUCHOT, 1987; DJABAL et al.,1993). Lepidorhombus boscii and L. whiffiagonis have recently been record ed in the Eastern Mediterranean Sea (GOLAN, 1996). However, only Lepidorhombus boscii has been recorded in the Turkish Seas (FSCHER et al., 1987; KAYA, 1993; ANONYMOUS, 1993). On the other hand, L. whiffiagonis has simply been listed among fishes distributed in Turkish waters but without any explanation such as date, location, morphological features etc., and without any references. Thus with this brief communication L. whiffiagonis has been for the first time officially record ed in the Turkish waters in spite of its presence in the species list given by NELSEN (1986), AK~RAY (1987), MATER and :MER(: (1996) and FROSE and PAUL Y (1999). MATERALS AND METHODS Four specimens of the species have been captured by a commerciai trawl ( m depth) in skenderun Bay (36 50'N; 36 00'E) in May The specimens have been identified as L. whiffiagonis by using diagnostic characteristics described by NELSEN (1986).The specimens were kept in laboratories of Faculty of Fisheries, The University of Mustafa Kemal. RESULTS AND DSCUSSON Morphometric measurements and meristic counts of the specimens are shown in Table 1, and its picture is given in Fig. 1. Fig. 1.

The present morphometric measurments and meristic counts of L: whiffiagonis is in congruent with the other studies (D 85-91, A 67-75, LL , JARDAS, 1996; D 85-94, A 64-74, LL , NELSEN, 1986; D 80-94, A 61-75, LL; DJABAL, 1999). All findings strongly declare that L. whiffiagonis is present in the Turkish territorial waters of the Mediterranean Sea. ACKNOWLEDGEMENTS We thank Prof Dr. Sava~ MATER for identification of L. whiffiagonis, and the University of Mustafa Kemal, Faculty of Fisheries, skenderun, Hatay, Turkey for financial support. 3
