The incidence of escaped farmed Atlantic salmon, Salmo salar L., in the Faroese fishery and estimates of catches of wild salmon
The proportion of Atlantic salmon escaped from fish farms and caught in the Faroese salmon fishery was estimated using scale analysis. Samples were obtained of fish landed in the commercial fishery from 1980/1981 to 1990/1991 fishing seasons and from research catches in the 1991/1992 to 1995/1996 se...

The proportion of Atlantic salmon escaped from fish farms and caught in the Faroese salmon fishery was estimated using scale analysis. Samples were obtained of fish landed in the commercial fishery from 1980/1981 to 1990/1991 fishing seasons and from research catches in the 1991/1992 to 1995/1996 seasons. The material collected was in some years limited to only part of the fishing season. The estimated proportion of farmed salmon in the fishery was relatively low from 1980/1981 to 1986/1987, but increased considerably thereafter, and reached a peak in the 1989/1990 fishing season when more than 40% of the catch was estimated to be of farmed origin. Later, the proportion declined, and in recent seasons the proportions of farmed salmon were estimated to be around 20%. These estimates were used to split the Faroese catch into wild and farmed components. It is concluded that if farmed components in salmon catches are not accounted for, catches of wild salmon will be overestimated and assessments of fisheries and stocks of wild salmon confounded. Furthermore, the increase observed in catch per unit of effort (c.p.u.e.) in the 1980s and early 1990s might have been caused by an increasing abundance of farmed salmon. |
