A meta-analysis of 15 papers examined the general impact of seabird BRD technology upon commercial longline fishing operations. Since there were relatively few papers with data suitable for meta-analysis, the researchers pooled studies with BRD-and fishery-related metrics included as covariates. The analysis found a small (9%) increase in target catch with BRD use in longline fisheries, while seabird bycatch was reduced by 89%. This pattern does not change with respect to geographic location or BRD type, indicating that efforts to reduce seabird bycatch are generally effective under different conditions.

This workshop presents information to fishery representatives in Latin America that will help them enter the certification process. For those that may have an issue with bycatch, the Global Bycatch Exchange can be a useful resource that presents information and potential solutions. This workshop gives an opportunity for fishery representatives to give feedback on what will make this tool more useful and user-friendly.

Harbor seals (Phoca vitulina) appeared to habituate to acoustic harassment devices placed on gillnets in the Oregon salmon fishery. Results, although inconclusive, demonstrate a possible reduction in damaged salmon, at least in the short-term.
