Honors student works on Elodea floatplane project with ISER's Schwoerer and Engineering's Witmer

ISER researcher Dr. Tobias Schwoerer and UAA Engineering Computer Science Professor Dr. Frank Witmer are working with UAA Honors student Devin Boyle to get a better understanding of how Elodea, an invasive freshwater plant in Alaska, is being spread across Alaska by float planes. Funded with an Honors College grant and support from Rust’s Flying Service, the project involves investigating the feasibility of using images captured by cameras installed on float planes as part of a “big data” citizen science project.

How Data on Cross-fishery Networks of Permit Holders Could Help Managers

Alaska has hundreds of commercial fisheries, and fishery managers issue unique permits for each fishery. But in a new blog post, Matt Reimer, an ISER economist, and his co-authors report that many of those who fish in Alaska waters have multiple permits, allowing them to take catches in different fisheries. That means if managers change a policy for one fishery—for instance, reducing the catch limit—permit holders could react by changing where they fish, going after different species, or using different gear.

So how can managers assess whether a policy change in one commercial fishery might have such unintended consequences in others? Matt Reimer and his co-authors argue that having statistical data on cross-fishery networks among permit holders—and analyzing those data—could help managers better understand the potential spillover effects of changing policies for a given fishery. The authors also created an interactive map, showing existing cross-fishery networks. Check out the blog.

Talk at ISER: Iceland’s Fisheries: An Overview and Description of Management

Hreiðar Þór Valtýsson and Hordur Saevaldsson are both assistant professors in the School of Business and Science at the University of Akureyri in Iceland. At ISER, they each talk about aspects of Iceland’s fisheries, which have for centuries been the main pillar of the Icelandic economy.

Hreiðar Þór Valtýsson gives an overview of the current status of the stocks around Iceland and speculate on the main drivers of change in those stocks. He also describes the tools used to manage the fisheries, so as to minimize discards and protect juvenile fish. Hörður Sævaldsson describes the history of fisheries management in Iceland, including precursors of the current system and today's ITQ (individual transferable quota) system—as well as the effects of consolidation and changes within the system.

Lunchtime Talk: A Framework for Valuing Commercial and Recreational Fisheries

Commercial and recreational fisheries are very different: the commercial fishery is a resource extraction, processing, and retailing industry; the recreational fishery is a form of outdoor recreation, influenced not only by the availability of fish but by the environmental setting and other factors aside from fish. How can we make a fair comparison of their economic value?

Gordon Gislason, a fisheries economist from Vancouver, British Columbia, talks about a framework he has developed for analyzing and comparing the economic value of the two kinds of fisheries. As a case study, he estimated the commercial and recreational values of Chinook salmon in Pacific Canada. Please join us to hear what he found.

Lunchtime Talk: Salmon, People, Place: Coastal Alaska Communities that Depend on Fisheries

In this presentation, Davin Holen, a Ph.D. candidate in the Department of Anthropology at the University of Alaska Fairbanks, will discuss his dissertation, which examines the intersection of commercial and subsistence fishing in Alaska for food security, culture, and community well-being. His multi-year project documents how the economic and cultural value of salmon promotes the long-term viability of coastal Alaska communities.

When: Friday, November 4, 12 to 1
Where: ISER Conference Room ,
Third Floor, 1901 Bragaw St, Suite 301.

Research Matters No. 96. Commercial Fishing, Mining, and Tourism: State Revenues and Spending

How do taxes and other revenues the state government collects from the commercial fishing, mining, and tourism industries compare with what the state spends to manage them? That’s the question the Alaska Division of Economic Development asked ISER researchers Bob Loeffler and Steve Colt to answer. In a new study, the researchers report their findings, but they first emphasize that their study is not a broad analysis of all the benefits and costs of these industries, which would also weigh many other factors—including the substantial income and thousands of jobs the industries generate for Alaskans. The researchers also point out that the state’s management goals for these industries include many things besides collecting taxes, and that their study does not say anything about what taxes on these industries should be.

The authors found that commercial fishing, mining, and tourism all generate combined state and local revenues in the same ballpark—averaging about $120 million to $135 million annually in recent years. All three industries pay more in combined state and local taxes than the state spends to manage them, with revenues from tourism and commercial fishing particularly important to local governments: 60% of the revenue from tourism and 40% from fishing goes to local governments. Counting only state revenues (excluding local revenues), the state spends more to manage fishing than it collects from the industry. State revenues from tourism roughly equal what the state spends for management. Mining brings in about six times more than the state spends to manage it.

Bob Loeffler is a visiting professor of public policy at ISER, funded by a grant to the University of Alaska Foundation from the Council of Alaska Producers. Steve Colt is a professor of economics at ISER. The report findings are those of the authors, not ISER, the University of Alaska Anchorage, or the research sponsors.

Lunchtime Talk: What Affects the Harvest in the Sitka Subsistence Herring Fishery?

Sitka Sound in Southeast Alaska is home to one of the state’s largest commercially viable stocks of Pacific herring, which are harvested for their roe (eggs) in the spring, just before they spawn. There is also a subsistence herring fishery in Sitka Sound, with subsistence users collecting the roe after the herring spawn. In recent years, the Alaska Department of Fish and Game has increased the commercial guideline harvest level—and conflict between commercial and subsistence fishermen has also increased. James Shewmake, a research professional at ISER, earned his master's in natural resource management for his research on the subsistence herring fishery in Sitka Sound. He found that the size of the subsistence harvest depends not only on how many people participate, but also on other measures of participants’ effort and on harvesting opportunities.

Lunch Talk: Fisheries Privatization, Sociocultural Transitions, and Well-Being in Kodiak

In the 1970s, the state and federal governments began "privatizing" access to Alaska's commercial fisheries—that is, they either issued permits or assigned shares of the catch to a limited number of fishermen. Those permits and quota shares are commodities that can be bought and sold on the market. Scholars and fishermen alike view this privatization as a fundamental driver of change in fishing livelihoods and communities. Courtney Carothers, an associate professor in the School of Fisheries and Ocean Sciences at UAF, has studied some of the social and cultural effects of the shift to privatization in Kodiak, one of Alaska's major fishing communities. Hear Dr. Carothers talk about the results of her research.

Economic Importance of the Bristol Bay Salmon Fishery

A new report by ISER economists Gunnar Knapp, Mouhcine Guettabi, and Scott Goldsmith assesses the economic importance of the Bristol Bay salmon fishery, the world's most valuable wild salmon fishery. Nearly half the wild sockeye salmon harvested worldwide come from Bristol Bay. The researchers found that as of 2010, Bristol Bay salmon created $1.5 billion in sales value across the United States—through harvesting, processing, and retailing of Bristol Bay salmon—and the additional economic effects of those activities.
