This is the first study to demonstrate river 31 flow impacts on the migration success of wild salmonid smolts at small weirs. Because small weirs 32 are common in rivers and because spring-summer low flow periods may become more frequent with 33 climate change (based on UKCIP09 models) and altered river hydrology, further research and 34 improved management is needed to reduce the impacts of low river flows in combination with low-35 head weirs on salmonid smolt migration. 36

Freshwater and coastal migration patterns in the silver‐stage eel Anguilla anguilla

“…anguilla to have emigrated before battery failure. Manufactures reported tag failure rate in tests as <1% and studies using the same tags, over the same period, have reported control‐tag failure rates in field environments of 0% (Gauld et al , ). There was no evidence of impaired migration related to tagging with c .…”

Does size matter? A test of size‐specific mortality in Atlantic salmon Salmo salar smolts tagged with acoustic transmitters

“…Transmitter failure rate reported by manufacturers is low (<2%); for Thelma transmitters of the same model used here, Gauld et al . () reported control transmitter failure rates of 0% within field test environments. Thus relevant precautionary steps were taken to maximize detection efficiency within the study and enable the determination of transmitter fate.…”

Atlantic salmon Salmo salar passing a natural barrier before and after construction of a hydroelectric station

“…Atlantic salmon Salmo salar L. 1758 stocks encounter a range of collective and sometimes undefined pressures such as those associated with unfavourable oceanic conditions (Jonsson et al ., ) or climate change (Gauld et al ., ; Jonsson & Jonsson, ). Additionally, some populations may also encounter more localised threats within their natal catchments.…”
