The GRT has launched a project to record sightings and the timing of grayling spawning; i.e. actually laying eggs, rather than just pre-spawning movements onto spawning areas, or pre-spawning behaviour, which are also of interest, but take place over a longer time. This study is being undertaken because there is little information on the timing of grayling spawning and how this varies across the country/continent.

It is hoped that the findings from this study will be used to inform the planning of in-stream engineering works and help protect important spawning habitat. If you are out on the river bank and notice grayling spawning, please let the GRT know: the River, Date, Location (NGR or marked up map if possible, but at least the nearest town/village) and any additional observations. To report sightings is easy: either fill the short form below or contact us.

Results will be mapped and displayed on the GRT website as they come in, and updated maps shown at AGMs.
