ABR is Thrilled to Announce a New Publication:

We are excited to share the release of a long-anticipated analysis of 30 years of subsistence harvest monitoring data collected on the Colville River delta (CRD) in collaboration with the community of Nuiqsut, Alaska.

The study, “Factors Influencing Harvest Success for an Arctic Under-Ice Subsistence Fishery,” recently published in Polar Science, analyzes a long-term fishery dataset. The findings reveal that, in addition to the recruitment of young fish to the river, factors such as westerly wind speed, salinity, and the week of the year significantly affect fish catch rates.

Long-term fishery datasets are particularly rare in Arctic environments and are essential for understanding the variability in harvest rates. The fishermen and women of Nuiqsut, as major stakeholders in the management of this fishery, play a key role. They work closely with local and regional governments, as well as industry partners, to ensure that harvest efforts and outcomes are carefully monitored. For decades, they have contributed local knowledge of fishery trends and reported daily harvest data to fishery monitors each fall.

Lead author John Seigle has spearheaded harvest data collection for the past 17 years, giving him deep insights into the factors influencing Arctic cisco harvests in the region. Equally important, the shared knowledge from the Nuiqsut community has significantly enhanced our understanding of long-term fishery trends on the Colville River delta.

This long-term monitoring effort, detailed in the study, will continue to play a vital role in informing sustainable fisheries management. It is particularly critical in the face of a rapidly changing climate and ongoing infrastructure development in the region.
