Sinigarra, new genus, is characterized by having the lower lip modified into a mental adhesive disc posteriorly discontinuous with the mental region. It is distinguished from all other disc-bearing genera, namely Garra, Placocheilus, Discocheilus and Discogo...

In order to determine some biological characteristics of Aksu stream Garra turcica population, 168 individuals were examined between 2013-2014. The ages the are 0 and IV. it was determined be between. Total lenght weight values calculated as 3.9-16.6 cm (8.54 ± 2.36 cm) 0.81-58.50 g (9.40 8.30 g), respectively. length-weight relationship W = 0,0145L2.9172. Growth parameters estimated L∞ 21.77 c...

The taxonomic status of Thamnurgus rossicus was evaluated with respect to the morphologically similar T. petzi using genetic markers. Nucleotide data from the mitochondrial COI gene revealed 2.4% variation between the European Alps and Russian steppe populations. The two nuclear DNA markers CAD and EF1á were identical across populations. In view of their similar morphology, genetic composition,...
