Assessing the impact of charr research past, present, and future

Abstract

The 9th International Charr Symposium convened on 18-21 June 2018, in Duluth, Minnesota, USA, to gather scientists with an interest in charr biology and management from the entire geographical range of the genus Salvelinus. The symposium was attended by 169 individuals from six countries, and included 99 oral and 32 poster presentations, 28 of which were published in the ensuing proceedings. Topic areas of presentations and publications included (1) cultural anthropology; (2) genetics, evolution, taxonomy, and systematics; (3) behavior, movement, and habitat; (4) reproductive ecology, developmental ontogeny, and physiology; (5) population ecology, dynamics, and life history; (6) trophic ecology, parasites, predators, toxicology, and pollution; and (7) management. Research reported in these proceedings has built upon the history of earlier symposiums and will be continued with the 10th symposium scheduled to convene in Nikko City, Tochigi Prefecture, Japan, in 2021.

Spatio‐temporal monitoring of lake fish spawning activity using environmental DNA metabarcoding

“…Arctic charr (Salvelinus alpinus L.) has the most northerly distribution of all anadromous freshwater teleosts (Hansen et al, 2019), ranging from the temperate areas of eastern North America and the European Alps, to the most northern points of the Eurasian and North American continents (Johnson, 1980). The species is adapted to cold, highly oxygenated waters and is therefore especially vulnerable to climate change and eutrophication (Winfield et al, 2008).…”

“…Anthropogenic pressures are threatening freshwater fish populations worldwide (Díaz et al, 2019), and conservation biologists and environmental managers are striving to preserve such diversity as it provides ecosystem services to humans and holds intrinsic evolutionary and ecological value (Lynch et al, 2016; Piccolo, 2017).
