Here we describe morphological, histological molecular characteristics sinova sp. nov. parasitizing gill arches tentacled blenny Parablennius tentacularis (Perciformes: Blenniidae) collected from coast Sinop on Black Sea in Turkey. Several oval whitish plasmodia different sizes fish were found. The mature spores rounded frontal view, with mean (range) total length 57.5...

Differentiation at nine microsatellite loci revealed that a Levantine Basin sea bass Dicentrarchus labrax population probably represents further subdivision of this species in the eastern Mediterranean.

The aim of this report is to provide an overview the current status efforts on potential rehabilitation sturgeon populations in Turkish waters, describing structure and outcome projects carried out since 2006 identifying strategic needs for conservation measures at a national level. It well known that there were six species occurring around Black Sea coasts while entering rivers, mainly Kızılırmak, Yeşilırmak, Sakarya Çoruh Rivers spawning. Anadromous have been strictly protected throughout...

Pseudophoxinus burduricus sp. n. is described from drainages of Salda and Burdur lakes, southwestern Turkey. It distinguished other Anatolian by a combination characters: lateral line incomplete, with 21-39 (commonly 26-37) perforated scales 47-57+1-2 in series; 10½-12½ scale rows between dorsal fin origin, 3-4(5) the pelvic origin; commonly 7½ branched rays; anal 6½ 7-8(9) gill rakers on first branchial arch; faint diffuse epidermal black stripe eye to caudal base alive preserved...

It has been assumed that sturgeons originated in the Tethys Sea, and Black Sea is their most important diversification center. Hence Turkey had a significant place throughout history. Although there are some genetic studies about sturgeon species inhabit these have not included samples from Turkey. In this study, phylogenetic relationship, cladistic positions, variations were determined Cyt-b (1141bp) mtDNA of 3 (n = 28), collected Turkish coast between 2005 2007. Nineteen haplotypes,...

The genus Chondrostoma (Leuciscidae: Leuciscinae), composed of small to medium-sized fish with a scraper feeding characteristic, is distributed in the West and Middle East, Caucasus, Europe Northern Mediterranean drainages. This spreads across Anatolia Thrace, exception Göksu Eşen rivers Turkey’s basin. It also difficult understand systematics , which complicated morphologically. Therefore, this study, an identification key was made by evaluating external morphology, osteology (some jaw...

Abstract We provide details of five microsatellite loci screened in 163 individual sea bass. Large numbers alleles were observed at three (20–25) and heterozygosities ranged from 0.52 to 0.86. These should prove useful for population genetic studies the pedigree analysis management this species aquaculture.

In a study of the fishes Büyük Menderes River Basin, Aegean region Turkey, two populations Chondrostoma were found which showed clearly distinctive characters: population from Upper B. (Işıklı Lake) was attributed to C. meandrense Elvira, 1987, while Çine Stream in Lower basin proved be hitherto undescribed species: turnai sp. n. Altogether 24 metric and 7 meristic parameters compared. The new species is distinguished all other cogeners by combination number lateral line scales, scale rows...

The molecular phylogeny of the Anatolian species genus Chondrostoma (Cypriniformes: Leuciscidae) was studied by sequencing mitochondrial cyt b gene. A total 144 tissue samples from 14 described were collected 35 different localities in Turkey. In total, 74 haplotypes identified. Haplotype network construction and phylogenetic analysis allocated all to two main haplogroups that are congruent with those currently accepted on basis morphological characteristics. first haplogroup, Nasus lineage,...

Abstract The genetic discrimination of two species the genus Capoeta, C. tinca (Heckel, 1843) and banarescui Turan et al., 2006, which is represented by many endemic in Anatolian Turkey, has been investigated analysing partial 16S ribosomal DNA gene (525 bp). A total 85 fish was sampled from localities Marmara basin 5 Black Sea basin. amount rDNA sequence divergence separating these taxa (mean 1.19%) within range observed for variation between other freshwater fishes. derived haplotypes (h:...

Abstract Members of the genus Ortholinea are among worldwide distributed myxozoan parasites that mainly infect marine fish. In this study, a new myxosporean species, hamsiensis n. sp., was isolated from urinary bladder European anchovy Engraulis engrasicolus collected Sinop coasts Black Sea. The prevalence and density values infection were 1.4% 1–5 individuals in field view (1 + ), respectively. Mature myxospores subspherical with slight tapering down to less pronounced tip frontal sutural...

Objective: To determine tandem repeat polymorphism and heteroplasmy in three sturgeon species (A. stellatus, A. gueldenstaedtii H. huso) from the Turkish coast of Black Sea. Methods: tRNApro D-loop segment mtDNA were amplified via PCR sequenced. For each species, homoplasmic individuals with different product lengths, motifs regions determined numbers frequencies calculated. The variation size present overall sample waters was apportioned into hierarchical components. Also, statistical...
