Field observations of deformed Atlantic salmon (Salmo salar) embryos incubated in the hyporheic zones of seven cold region rivers - Deformity dataset
The objective of this study was to report the prevalence of deformed Atlantic salmon (Salmo salar) embryos across a range of incubation habitats. We assessed 3234 embryos that had been incubated to approximately the “eyed” stage in simulated redds at 20 sites in 7 rivers across 2 basins (the Tobique...

We assessed 3234 embryos that had been incubated to approximately the “eyed” stage in simulated redds at 20 sites in 7 rivers across 2 basins (the Tobique and the Miramichi River basins of northern New Brunswick, Canada) over 3 winters (2012-2015).
