One specimen of the shortfin neoscopelid Neoscopelus microchir Matsubara, 1943, has been recorded for first time on Porcupine Bank, southwestern Ireland, providing a new northern limit distribution eastern Atlantic. Morphometric and meristic parameters confirm taxonomic identification. However, DNA barcoding shows deficiencies in current taxonomy potential occurrence cryptic species. On this ba...

In this paper, 981 reared juveniles of gilthead seabream (Sparus aurata) were analysed, 721 of which were from a commercial hatchery located in Northern Italy (Venice, Italy) and 260 from the Hellenic Center for Marine Research (Crete, Greece). These individuals were from 4 different egg batches, for a total of 10 different lots. Each egg batch was split into two lots after hatching, and reared...

In this study, we report new locality records for Eumeces schneiderii and Trapelus ruderatus from Malatya, Eastern Anatolia. As the is about 60 km north of known distribution area E. Malatya T. first record province. A summary metric meristic characteristics was with color-pattern features given these specimens. Moreover, explored locality’s importance species biogeography via Anatolian diagona...

The population structure of the bluefish, Pomatomus saltatrix (Linnaeus, 1766), in Turkish waters is scarcely described literature. To identify any distinct units and reaffirm findings a previous study, four areas were selected: Aegean Sea, western Black eastern Sea Marmara. In this truss network morphometrics, meristics, otolith shape analyses successfully applied for different identification ...

The Liolaemus elongatus group currently includes eight species (including the species described herein) of mid-sized, long-tailed, primarily saxicolous lizards. Members of this lineage are distributed in northwestern Argentina along the Andean Cordillera south to the Patagonian Steppe (27–448 S) and over a wide range of elevations (350–3900 m). Here we describe two new species belonging to the ...

Currently one small, native population of the culturally and ecologically important Lahontan cutthroat trout (Oncorhynchus clarkii henshawi, LCT, Federally listed) remains in the Truckee River watershed of northwestern Nevada and northeastern California. The majority of populations in this watershed were extirpated in the 1940s due to invasive species, overharvest, anthropogenic water consumpti...

—Hybridization with nonnative fishes is a major factor influencing the status of native catostomids in the Colorado River basin. In Wyoming, hybridization with nonnative white suckers Catostomus commersonii is a particular concern in the conservation of native bluehead suckers C. discobolus and flannelmouth suckers C. latipinnis. The purpose of this study was to describe the meristic and morpho...

In a study of the fishes Lake Hazar, and Tigris, Euphrates Kueik rivers were recorded four species Squalius belonging to Squalis cephalus-group found: The western drainage River (Tohma Stream) population was identified as S. seyhanensis, northern drainages semae, populations berak. comparison 28 metric, 9 meristic parameters morphological characters showed that Hazar upper Tigris are distinct b...
