Abstract

Salmo duhani, sp. n., a new species, is described from the southern Marmara Sea drainages, Turkey. It differs from the other Salmo species in the neighboring basins by having a shorter maxillary (8-10% SL); a shorter head (24-28% SL); 115-121 lateral line scales; 26-29 scale rows between lateral line and dorsal-fin origin; 20-23 scale rows between lateral line and anal-fin origin; 15-17 scales between lateral line and adipose-fin insertion; 17-19 gill rakers on the outer side of first gill arch; 10-13 large and oblong parr marks along the lateral line in all individuals.

Marmara Denizi'nin güney drenajından yeni bir alabalık türü (Teleostei: Salmonidae)

Abstract

Yeni bir tür olan Salmo duhani Türkiye'nin güney Marmara Denizi drenajından tanımlanmaktadır. Türün yakın havzalarda dağılım gösteren diğer Salmo türlerinden farkı: maksiller kısadır (% 8-10 SB); baş boyu kısadır (% 24-28 SB); ligne lateral pul sayısı 115-121; ligne lateral ile dorsal yüzgecin başlangıcı arasındaki pul sıra sayısı 26-29; ligne lateral ile anal yüzgecin başlangıcı arasındaki pul sıra sayısı 20-23; ligne lateral ile adipoz yüzgecin başlangıcı arasındaki pul sıra sayısı 15-17; birinci solungaç yayının dış tarafında bulunan solungaç dikeni sayısı 17-19; bütün bireylerde yanal çizgi boyunca büyük ve dikdörtgen şeklinde 10-13 par bulunmasıdır.
