Razor clam surveys - Firth of Clyde and Solway: report
This report describes a survey carried out in the Firth of Clyde (2023) and Solway (2024) to estimate the densities and sizes of razor clam, Ensis siliqua. The surveys were conducted as part of the Scottish Government’s electrofishing scientific trial.
