Data are initially restricted, but the access condition relaxes to academic or unrestricted once a specified period of time after an event (such as collection, publication, completion of QC procedures or project cessation) has elapsed

This study investigated the upstream spawning migration of anadromous river lamprey (Lampetra fluviatilis) in the Yorkshire Ouse, a highly dendritic and heavily fragmented tributary of the Humber Estuary (home to one of the largest UK river lamprey populations). The main English lamprey fishery operates within the tidal reaches of the Yorkshire Ouse. The study occurred over two consecutive (2018/19 & 2019/20) and highly contrasting (dry & wet) flow years. River lamprey were PIT and acoustic tagged and released at three different locations. All PIT tagged lamprey were released at Cawood, downstream of the commercial fishery and Naburn Weir. Acoustic (and PIT) tagged lamprey were evenly split between Cawood, upstream of the first (Naburn Weir) and second (Linton Weir) main river barriers. Overall, the study examined commercial fishery exploitation as well as the catchment-wide migration and the impact of the two large main river barriers on onward migration. more

The study cover the river Yorkshire Ouse from Cawood to the fourth weir encountered in the rivers Wharfe (Wetherby Weir) and Nidd (Knaresborough Lido Weirs), the third weir encountered in the River Ure (WestTanfield Weir) and Maunby/Morton Bridge on the River Swale (upstream of both weirs on that tributary). The first barrier on the River Derwent (downstream of Cawood) was also monitored.
