Salmon fry densities on the river Dee were estimated from juvenile electrofishing data using a capture probability model initially developed in 2015. The resulting density estimates were compared to two potential reference levels that also varied by habitat; (1) a mean National Reference, and (2) a Dee Reference. Despite the limitations of the current approach, it provides useful insights into status of salmon on the River Dee and with future developments will offer a useful assessment to complement those based on adult returns.
