Trials and Tribulations of a Purse Line

Our chartered vessel, the Island C, is currently warming up its engines as we prepare to head for Izhut Bay.  We have been down in Kiliuda Bay for the last four days, and steamed in to Kodiak early this morning for water, supplies, and a few other needed things. Having a stop back in Kodiak after doing the first bay of the trip is very valuable, as it allows us to figure out if there is anything that needs replacement, repair, or enhancement.

For example, the first couple of days in the skiff convinced me that our little purse seine wasn’t working as it should. A purse seine is a net that is set in a circle, so that it forms a circular wall- corks on top of the net to float it, weighted lead line (as in the the metal) on the bottom. After we get the seine set in a circle, we pull in a line running through runs along the leadline. This pulls the bottom of the net together, forming a large bag or purse and keeping any fish inside the net from escaping. Much larger versions of this net are used by commercial fishers to catch salmon, tuna, and herring; our little net is twenty feet deep and forms a circle about 40 feet in diameter. We have found that this is a great tool for sampling nearshore habitat.

Recently, however, we have been having increasing problems with the purse line getting wrapped in the web, and we noticed that the purse line was getting pretty chafed after being dragged through numerous types of kelps, eelgrasss, barnacles, and gravel. So this morning we went off to Kodiak Marine Supply and got ourselves a shiny, smooth new purse line. We’ll string the new line as we steam up to Izhut and should be ready to drop the skiff in the water later this afternoon! More in a week or so.

WHo we are

Established in 2001, NPRB is a marine research organization that supports pressing fishery management issues or marine ecosystem needs.


More than 600 peer-reviewed publications have been produced through NPRB-funded research. Browse our library and our reports here.


NPRB comprises a 20 member Board, representing Federal, State, and other entitites while receiving advice from Science and Advisory Panels.


Looking to partner with NPRB? NPRB welcomes partnerships to co-fund research in areas of common interest and across its programs.


NPRB communicates and engages with a broad and diverse set of Alaskan stakeholders and audiences, from coastal communities to academia.


NPRB staff support the Board, Science, and Advisory Panels for funding decisions, science priorities, recommendations, and program management.

Funding Available

The Core Program offers year-round funding with flexible rolling submission options.


NPRB staff begins developing draft research priorities for the Core Program in late July and August. Submit before July 2nd to be considered for the current year’s RFP development. 

Our Programs

NPRB maintains scientific programs designed to address pressing fishery management issues and Alaska marine ecosystem information needs.


NPRB supports a competitive, peer-reviewed annual request for proposal (RFP) process dedicated to marine research in Alaskan waters.

The Arctic Integrated Ecosystem Reserach Program looked at how physical changes in the ocean influence the flow of energy through the marine food web in the Bering Strait, Chukchi Sea, and western Beaufort Sea from 2017-2021.


Supporting science communication, engagement, outreach, and education initiatives for all our research programs.


This program supports new or existing time-series research that enhance the ability to understand the current state of marine ecosystems.

The Bering Sea Project, a partnership between the North Pacific Research Board and the National Science Foundation, sought to understand the impacts of climate change and dynamic sea ice cover on the eastern Bering Sea ecosystem.


These are large-scale interdisciplinary ecosystem-based programs, requiring multiple agency coordination, collaboration, and investigation.


NPRB supports next generation scientists, researchers, and resource managers to further their studies in relevant fields of marine science and to our mission.

The Gulf of Alaska Project tested three main hypotheses about the survival and recruitment of five focal groundfish species (Pacific cod, Pacific ocean perch, walleye pollock, arrowtooth flounder, sablefish) during their first year of life.
