“…The flathead trout's morphological and life history characteristics were addressed by Kara et al [15,16]. Recently, flathead trout populations are critically endangered by habitat loss and stockings of non-native trout [17].…”

“…Actually, the very first plots of S. salar are already available by Matoulek et al [26], in three different resolutions, i.e., different sliding window sizes, (https://github.com/bioinfohk/evangelist_plots). However, S. salar belongs to the karyotype category B sensu Phillips and Ráb [17], i.e., salmonids with 2n =~60 (54-58) and chromosome arm number NF = 72-74. Hence, Salmo trutta Linnaeus, 1758, with a karyotype more similar to S. platycephalus, is more desirable for cytogenomic comparisons.…”

Salmonids are extremely important economically and scientifically; therefore, dynamic developments in their research have occurred and will continue occurring in the future. At the same time, their complex phylogeny and taxonomy are challenging for traditional approaches in research. Here, we first provide discoveries regarding the hitherto completely unknown cytogenetic characteristics of the Anatolian endemic flathead trout, Salmo platycephalus, and summarize the presently known, albeit highly complicated, situation in the genus Salmo. Secondly, by outlining future directions of salmonid cytogenomics, we have produced a prototypical virtual karyotype of Salmo trutta, the closest relative of S. platycephalus. This production is now possible thanks to the high-quality genome assembled to the chromosome level in S. trutta via soft-masking, including a direct labelling of repetitive sequences along the chromosome sequence. Repetitive sequences were crucial for traditional fish cytogenetics and hence should also be utilized in fish cytogenomics. As such virtual karyotypes become increasingly available in the very near future, it is necessary to integrate both present and future approaches to maximize their respective benefits. Finally, we show how the presumably repetitive sequences in salmonids can change the understanding of the overall relationship between genome size and G+C content, creating another outstanding question in salmonid cytogenomics waiting to be resolved.

“…S. platycephalus population in Zamantı Stream are endangered and it is under threatend beceuse of fishing pressure, pollution and competition of nonnative fish (Tarkan et al, 2008). A predator fish, Esox lucius, was introduced in this habitat and this has predator effect on the S. platycephalus population.…”

“…This species have taken in the IUCN Red List of Threatened species (IUCN, 2003;Tarkan et al, 2008). In this study, therefore, for the management propose as well, age, growth and reperoduction properties of Salmo platycephalus living in Zamantı Stream were investigated.…”

In this study the growth and reproductive features of the flathead trout (Salmo platycephalus) found in the IUCN red list of threatened species in Zamantı Stream of Seyhan River were investigated. The population was composed of 50.44 % female, 40.71% male and 8.85% immature individuals. The fork lengths (cm) and total weights (g) of the individuals varied between 11.3 to 40.1 cm and 19.7 to 988.7 g, respectively. Ten age groups (1 to 10) were identified in the population and majority of the sample was between 26.0 to 38.0 cm (69.91%) and 36.28% was between 410 and 660 g in weight. The length-weight relationship for all sample was W = 0.016*FL 2.938 with R 2 = 0.989. The growth parameters was estimated as; L ∞ =60.78 cm, K=0.091 and to=-1.72. The condition factors varied from 1.04 to 1.93 and the differences in condition between female and male was not significant (P>0.05). According to GSI and agg dimaters, spawning period was determined between October and December. Mean fecundity was 2,398 egg/fish, egg diameters was between 4.387 and 5.408 mm (mean diametrers was 4.782 mm) on mature individuals in reproductive periods.

“…Salmo platycephalus has a very restricted distribution in Zamantı stream system. In recent years, weight and condition factors (Alp and Kara, 2004), philogenetic traits (Sušnik et al, 2004;Bardakçı et al, 2006) and conservation status (Tarkan et al, 2008) of S. platycephalus were investigated. Different populations of the same fish species are often different in phenotypic characters (Pakkasmaa and Piironen, 2001;Sandlund et al, 1992;Schluter and McPhail, 1992;Eliot, 1994).…”

In this study, morphometric and meristic characters of trouts (Salmo trutta and Salmo platycephalus) were investigated in the upper basin of Seyhan, Ceyhan and Euphrates rivers. According to Principal Component Analysis (PCA) has been determined that morphological variations were determined among the populations. Salmo platycephalus population in Seyhan River formed different cluster from S. trutta on the graphic. S. platycephalus living in Seyhan basin differ from S. trutta living in Ceyhan and Euphrates basin by the number of pyloric caeca, gill rakers, head depth and predorsal on outer side of first gill arch.
