Die fünf Arten der Gattung Thymallus
sind in den nördliche Gebieten der Nordhalbkugel verbreitet.
The specimen scanned here was collected in Michigan, but those populations are now extinct.
There are many named forms of grayling, but the most recent works classify the genus into two species, one in North America (Thymallus arcticus) and one in Eurasia (Thymallusthymallus).
Graylings are considered the sister group to the Salmoninae, trouts and salmon, and as such are frequently used as an outgroup for studying relationships of those taxa.
The dwarf Arctic grayling, Thymallus arcticus, was found in a group of small lakes which feed into the Yakchii stream, a tributary of the Verkhnyaya Angara River in the basin of Lake Baikal.
The new fish looks similar to Thymallus arcticus in the upper Lena River and shares similar body colouration and a characteristic pattern on the Grayling's large dorsal fin.
One species, Thymallusthymallus, is found in the UK and primarily occurs in flowing freshwater rivers.
The phylogeography of an endangered salmonid, European grayling (Thymallusthymallus), was studied based on analysis of 17 nuclear microsatellite DNA loci.
In agreement with earlier mitochondrial DNA (mtDNA) studies, phylogenetic relationships of the populations suggested that northern Europe was colonized from two distinct Pleistocene refugia.
thymallus has strikingly low levels of intrapopulation genetic diversity as compared with other freshwaterfishspecies.
The Grayling, or Thymallusthymallus as it is scientifically termed- so called because of wild thyme smell, is one of the most beautiful, most respected and loved yet also the most victimised freshwaterfish in the northern hemisphere.
The rest of the world's grayling, including our own, the European grayling, and the Arctic grayling are nowadays considered to be one species - Thymallusthymallus or a pair of closely related species.
The grayling, whilst being members of the salmonfamily, spawn in the Spring - leading, of course, to the misconception that are one of the coarse fishes.
These, and additional studies, have revealed a high level of genetic structuring in these species, and the findings have directly resulted in Finnish fisheries authorities altering their stocking practices to take into account the evolutionary history of the populations.

grayling fishing(Site not responding. Last check: 2007-11-04)
Grayling are bottom dwelling fish, they feed mainly on nymphs, shrimps, worms and larvae and other river borne foods but they do rise keenly to the surface for hatching flies and often take them with a delicacy that belies the fish’s size.
There are two species of grayling in Europe, the common European speciesThymallusthymallus and the Arctic graylingThymallus articus articus which inhabits the northern countries, Norway, Finland and Sweden.
The feeding habits of both species are broadly similar but the Arctic grayling also lives happily in lakes.
Generally grayish-silver overall, grayling usually have shades or highlights of gold and/or lavender, as well as many dark spots which may be shaped like Xs or Vs on some fish.
