The relationship between a summer fry (0+) abundance index, derived from semi‐quantitative electrofishing, and egg deposition of Atlantic salmon, in the River Bush, Northern Ireland
Atlantic salmon survival in the R. Bush (N. Ireland) from egg to summer 0+ was inversely density‐dependent on egg deposition ( P <0.05). A stock‐recruitment relationship derived from egg deposition and summer 0+ abundance index data was compared to that derived from adult and smolt counts based o...
