In this research, length-weight relationships and meat yields of freshwater crayfish (Pontastacus leptodactylus) were investigated in Apolyont Lake, İznik Lake, Manyas Lake, Terkos Lake, Küçükçekmece Lake, Sera Lake, Çıldır Lake, Ulugöl Lake and Eğirdir Lake between July and September 2010. For this purpose, 698 individuals were sampled from nine d...

Brown trout, Salmo trutta is a widespread fish species throughout the Europe yet most of the natural populations of the species is in decline due to the anthropogenic pressures. Hatchery based stock enhancement is commonly used to restore depleted populations. Tracking pedigree information is useful for evaluating performance of stocked offspring a...

This study aimed to investigate the genetic diversity and population structure of Wels catfish Silurus glanis L. 1758 in Turkey using squences of the mitochondrial DNA control region The 887-bp fragment of D-loop was aligned for 112 S. glanis individuals from ten wild populations in Turkey, defined by 29 polymorphic sites comprising 16 haplotypes....
Article
Paracobitis salihae, new species, from the Göksu River in the western upper Euphrates drainage, is distinguished from other Paracobitis species by possessing a truncate caudal-fin, and a dark-brown vermiculate or marbled colour pattern. It is also characterised by 19 variable nucleotide substitutions, three diagnostic nucleotides and 3.6% minimum K...
Article
Oxynoemacheilus cilicicus, new species, is described from the Göksu, Seyhan and Ceyhan rivers in southern Turkey. It is distinguished from other Oxynoemacheilus species in the Eastern Mediterranean Sea basin by possession of an incomplete lateral line, terminating before the vertical of the dorsal-fin origin or slightly behind the dorsal-fin base,...
Article
The purpose of the current study was to evaluate culturing potential of Brown trout (Salmo trutta) strains belonging to Danubian lineage and their reciprocal crosses. Using all possible combinations F1 generation cross-types were produced by crossing Abant (A), Black Sea (L), Caspian (C) and Anatolian (F) strains of brown trout which were previousl...

Salmo fahrettini, a new species, is distributed in the northern tributaries of the Euphrates River. It differs from other Salmo species in adjacent waters by a combination of the following characters: a greyish body; one black spot behind the eye and on the cheek; three to six black spots on the opercle; numerous black spots on the back (missing on...

Brown trout (Salmo trutta) has a wide natural distribution range extending from Europe to Asia and Africa. With other salmonids, it exhibits high polymorphism depending on life histories and ecology; mostly manifests as several phenotypes varying in morphology, colour patterns and behaviour even in sympatric species. However, traditional molecular...

We tested for reproductive isolation between Salmo trutta abanticus, S.t. labrax, S.t. caspius and S.t. fario by conducting crosses to produce F1 and F2 offspring. We also estimated the extent of genetic divergence between all three entities by examining sequence variation across the coI, d‐loop and cytb mitochondrial genes. All of the F1 cross‐typ...

The identification of taxa and discernment of evolutionary relationships within the family Dreissenidae have been confounded by morphological plasticity as well as prior lack of a comprehensive DNA sequence data analysis. We thus analyzed the phylogenetic relationships of putative taxa (species and subspecies) in the genus Dreissena in relation to...
