Assessing Adaptive Genetic Variation for Conservation and Management of the European Grayling (Thymallus Thymallus)
Assessing adaptive genetic variation for conservation and management of the European grayling (Thymallus thymallus) J. V. Huml PhD 2017 Assessing adaptive genetic variation for conservation and management of the European grayling (Thymallus thymallus) Jana Vanessa Huml A thesis submitted in partial fulfilment of the requirements of the Manchester Metropolitan University for the degree of Doctor of Philosophy 2017 Faculty of Science and Engineering Manchester Metropolitan University Abstract In this PhD, functional genetic variation of European grayling (Thymallus thymallus) is assessed to inform conservation and management of the species. This study is the first to characterize immune variation at the Major Histocompatibility complex (MHC) in grayling. The MHC is a marker of high ecological relevance, because of the strong association between immunity and fitness. Taking advantage of advances in sequencing technology, an analytical pipeline optimized for high-throughput, efficient and accurate genotyping of multi-gene families in non-model species is presented. Immune genetic variation is compared to neutral marker data. Results confirm the hypothesis that neutral marker variation does not predict immune genetic variation. Further, the possible effect of supplementing wild populations with hatchery-reared fish on immune genetic variation is evaluated. Significantly lower estimates of heterozygosity were found in stocked than purely native populations. Lower differentiation at immune genes than at neutral markers are indicative of the effects of balancing selection acting upon the MHC, within purely native, but not stocked populations. Furthermore species distribution modelling is used to identify environmental parameters shaping the distribution of grayling. To evaluate risks imposed by climate change, the sensitivity of grayling to climatic variables and range changes under predicted future scenarios are assessed. -

Abstract Huchen or Danube salmon (Hucho hucho, Linnaeus, 1758) is an economically and ecologically valuable salmonid species, among the most endangered fish species inhabiting the Danube basin. Consequently, appropriate conservation measures are required to prevent the species extinction. Although H. hucho is a poorly studied species, there are several studies on other salmonid species regarding fast growth markers. Following these studies, the main purpose of the current study was to determine growth-related SNPs in myostatin gene in H. hucho. Therefore, we analysed 20 aquaculture individuals of same age separated in two groups according length and weight, by sequencing the amplification product of SaMSTNb23 and SaMSTNb33 primers pairs. We also statistically analysed the differences in the development of individuals over time regarding total length, weight and head length. Significantly variations were observed (p < 0.001) for the measured traits in both groups. Regarding the genetic analysis, we observed nine SNPs in the mstn gene structure. Considering these results, it appears that the analysed markers are not appropriate for genetic analysis of growth traits in H. -

KALINOWSKI Department of Ecology, Montana State University, Post Office Box 172460, Bozeman, Montana 59717, USA Abstract.—The fluvial Arctic grayling Thymallus arcticus is restricted to less than 5% of its native range in the contiguous United States and was relisted as a category 3 candidate species under the U.S. Endangered Species Act in 2010. Although fluvial Arctic grayling of the lower Gibbon River, Yellowstone National Park, Wyoming, were considered to have been extirpated by 1935, anglers and biologists have continued to report catching low numbers of Arctic grayling in the river. Our goal was to determine whether a viable population of fluvial Arctic grayling persisted in the Gibbon River or whether the fish caught in the river were downstream emigrants from lacustrine populations in headwater lakes. We addressed this goal by determining relative abundances, sources, and evidence for successful spawning of Arctic grayling in the Gibbon River. -

Department of the Interior Bibliographies of individual species become more convenient and more necessary as the amount of fishery literature increases. For a declining species such as the Arctic grayling, the bulk of the literature is in older works. Bibliographic references to these articles are widely scattered and many are difficult to locate; few are listed in modern fishery bibliographic sources. The bibliography includes only a few major European and Asian references. Many of the early American articles are what would now be considered semipopular.

Journal of Wildlife and Biodiversity, 5(2), 99-102. doi: 10.22120/jwb.2020.132128.1173 Abstract During 2007-2018, a total of 451 specimens of the European grayling Thymallus thymallus from drainage basins of the Neva River, Onega River, Severnaya Dvina River, Pechora River, and the upper Volga River were collected by angling, electrofishing, gill netting, and seine netting. According to the results of the analysis of length-weight relationships, the regression parameter b ranged from 2.83 to 3.25, indicating shifts of the growth pattern, from negative-allometric to positive-allometric. The values of the coefficient of determination were greater than or equal to 0.97. The results of this study are useful for grayling’s stock management and conservation efforts in the region. Keywords: Fish, LWR, linear regression, standard length, total weight.
