RESUMO
Caligus diaphanus Nordmann,1832 (Copepoda; Caligidae) was reported for the first time from the gill chambers and inner faces of opercula of Chelidonichthys lucerna (Triglidae) from Aegean Sea Coasts in Turkey. Some morphological characters of this parasitic copepod are given using photograph and drawings.
Caligus diaphanus Nordmann, 1832 (Copepoda; Caligidae) foi relatado pela primeira vez das câmaras branquiais e faces internas dos opérculos de Chelidonichthys lucerna (Triglidae), do Mar Egeu, nas costas da Turquia. Alguns caracteres morfológicos deste copépode parasitário são apresentadas através de fotografia e ilustração.

Metric and meristic characters are important to identify fish species and their habitat peculiarities. There are many species that belong to the fish genus Barbus, which is found in tropical and extratropical regions, but there are few studies covering the Coruh basin. Two subspecies of Barbus were found in the Coruh River system of Eastern Anatolia, Turkey: Barbus plebejus escherichi and Barbus capito capito. We collected specimens in seven localities for measurement. The number of vertebra were determined radiographically. Some specimens of B. capito capito have a sharper snout in the segments of Coruh where the water flows faster, suggesting a modification related to current. The biometric measurements vary geographically and could be related to abiotic and biotic factors in the habitat.
