The Grayling Research Trust was formed in 1994 to provide facilities for study and research related to grayling, their habitats, ecology, water quality and environment, particularly to safe guarding and improving the same.

The Grayling Research Trust organises, funds or provides facilities for lectures, courses, demonstrations, instructions and publications whose aim is to encourage public interest in and awareness of grayling populations, the results of recent research on grayling, and the need for their conservation.

The Grayling Research Trust is a Registered Charity in England and Wales No: 1043994

Grayling Ecology

To help improve the understanding of grayling, we have produced a series of articles which explain the different species of grayling. Currently our website concentrates on the European grayling, Thymallus thymallus, providing information on lifecycle, habitat, feeding, spawning, migration, age and growth and competition.
We are continuously updating our material and will soon be adding information on the other species of grayling, if you have any information which you think will be useful , then please do not hesitate to contact us.


The Grayling Research Trust awards small grants for study and research related to grayling, their habitats, ecology, water quality and environment. The trust has been in a fortunate position where it has funded or part-funded a number of regionally and nationally important projects. A selection of such projects included:

New DNA study needs Anglers help!

In 2008/09, anglers collected over 1100 grayling adipose fin clip samples from 27 catchments the UK. The samples were used to extract DNA and for the first time, help us understand the genetic make up and diversity of grayling across the UK. This information was later used to influence stocking of UK grayling (Summary).

We now have another genetic study and need new samples. However, instead of fin clips we will be using swabs (cotton buds) to collect DNA from the mouth and gill cavity. The sampling invloves taking a swab of the mouth and gills of fish, an estimate of fork length and condition of the fish and a record of the date and geographic location. We need a minimum of 30 samples per catchment. If you feel you are able to contribute samples to the project, please contact us. Further details.
