Grayling Weight Survey

The GRT has launched a project to record the length and weight of grayling. The length/weight (condition factor) of a grayling may vary across the country/continent. There will be seasonal variation, as fish lose and gain weight depending on the food availability and the onset of spawning. This study is being undertaken because there is little information on the condition factor of grayling. It is hoped that the findings from this study will be used to gain a better understanding of grayling populations. To make reporting fish lengths and weights easy, a short submission form is available below or simply tweet (@GRT_Updates or #graylingweight).

Please fill in all required fields.

Information from this survey will be feed into our condition factor tool.

River Rother

On the 25th of June the Environment Agency stocked 3000 0 to 1 year class Grayling in the River Rother at Chesterfield. This is the first of three stockings planned (3000 Grayling in 2016 and 3000 more in 2017).

For several years Grayling have been caught by local anglers in small numbers but this stocking program by the Environment Agency will add to the existing small population but also shows the EA's confidence in the improving quality of the river.
