Despite the great potential of single nucleotide polymorphism (SNP) markers in evolutionary studies, in particular for inferring population genetic parameters, SNP analysis has almost exclusively been limited to humans and 'genomic model' organisms, due to the lack of available sequence data in non-model organisms. Here, we describe a rapid and cost effective method to isolate candidate SNPs in...

Acoustic telemetry was utilized to track 49 brown trout (Salmo trutta) and 37 Arctic charr (Salvelinus alpinus) first-time migrants of wild origin [post-smolts; mean LF (fork length): 169 172 mm] in a large fjord northern Norway. The S. trutta were registered at sea for more than twice the time alpinus (medians 54 22 days, respectively). Both species mostly detected near river mouths (>80% dete...

Fish cells attached to hyphae were observed in brown trout Salmo trutta L. infected with Saprolegnia parasitica. Earlier studies with light microscopy indicated that these cells were lymphocytes and neutrophils and that they were involved in the defence mechanisms against Saprolegnia infections. However, using electron microscopy, we found these attached cells did not show leucocytic characteri...

In the present study, we identified free amino acid (FAA) contents and chemical composition in four populations of Salmo trutta macrostigma living in Mediterranean region of Turkey. In addition, taste impacts of FAAs were evaluated by taste active values. Moisture, protein, fat and ash content were found in the ranges of 75.49 - 79.59 %, 16.94 - 19.97 %, 1.58 - 3.75 % and, 1.39 - 1.56 %, respec...
