Established populations of ranched Atlantic salmon with well described rates of return were chosen to investigate the potential contribution of early infestation with the salmon louse, <i>Lepeophtheirus salmonis</i> to mortality in Atlantic salmon. Results of five releases from four locations are presented and compared with a time series of releases from Lough Furnace in Newport, County Mayo. The results of this study would suggest that infestation of outwardly migrating salmon smolts with the salmon louse (<i>L. salmonis</i>) was a minor component of the overall marine mortality in the stocks studied.Digital Object Identifier http://dx.doi.org/10.1016/j.aquaculture.2011.06.042 收起
