Stock and recruitment and inversely density‐dependent growth of salmon, Salmo salar L., in a Scottish stream
For the 6 years for which detailed data are readily available, estimates of the survival of emergent fry of Atlantic salmon, Salmo salar L., to the first and second autumns at a site on the Shelligan Burn are consistent with the dome‐shaped Ricker model with about 11 emergent fry m −2 maximizing rec...

Summary: | For the 6 years for which detailed data are readily available, estimates of the survival of emergent fry of Atlantic salmon, Salmo salar L., to the first and second autumns at a site on the Shelligan Burn are consistent with the dome‐shaped Ricker model with about 11 emergent fry m −2 maximizing recruitment. The data are not satisfactorily fitted by the asymptotic Beverton and Holt model. A possible mechanism, which results from the observed inversely density‐dependent growth, is discussed briefly. |
