ABSTRACT

We compared entanglement rates of seabirds and marine mammals and catch rates of salmon among up to three experimental gear treatments and a control(nylon monofilament netting) and among three time-of-day categories in two Washington non-treaty salmon fisheries: the 1996 sockeye fishery in Management Area 7, the San Juan Islands vicinity of North Puget Sound, and the 1995 fall chum fishery in Management Area 10, South Puget Sound.   Results of this study identify three basic tools that can be used to reduce seabird bycatch in these fisheries: abundance based or ecosystem management, traditional monofilament nets modified to include a 20 Mesh visual barrier, and time-of-day.   Management recommendations were developed to reduce seabird bycatch in drift gillnet fisheries through institutional and fishery changes.  For the first time tools have been developed and implemented to reduce seabird bycatch in nearshore gillnet fisheries.
