Commercial Fishing Behavior under Changing Ocean Conditions: Spatial Analysis of the US West Coast Salmon Fishery

Creator:: Speir, Cameron and Thomas-Smyth, Alice
Abstract:: In this paper we characterize changes in the level and spatial distribution of fishing effort during the extreme ocean temperature event known by oceanographers, climate scientists, and the public as “the Blob.” The Blob was an unprecedented marine heatwave that occurred off of the Pacific Coast of North America from...

Measuring Health Outcomes in Fishing Industry Participants and Fishing Communities Using the Behavioral Risk Factor Surveillance Survey (BRFSS)

Creator:: Ridings, Cory, Speir, Cameron, and Drexler, Mike
Abstract:: The status of fishing industry participants and fishing communities is an increasingly important consideration in marine ecosystem models and in fisheries management. Metrics that reliably measure economic, health, and other dimensions of human well-being are required to analyze the impacts of changes in marine ecosystems and policy. To date, most...

Assessing the Accuracy of High Spatial Resolution Effort Data: Comparing VMS and Logbook Data in the California Groundfish Trawl Fishery

Creator:: Thomas-Smyth, Alice, Mamula, Aaron, and Speir, Cameron
Abstract:: Fisheries management is increasingly being conducted at finer scales of spatial resolution. The spatial distribution of fish stocks is recognized as being an important aspect of stock abundance and spatial management tools, such as marine reserves, have become common. Information on the spatial distribution of fishing effort is critical to...

The ecology and production dynamics of four black fly species (Diptera:simuliidae) in western Oregon streams

Creator:: Speir, Jon A.
Abstract:: Ecological and production studies of Prosimulium caudatum Shewell, P. dicum Dyar and Shannon, Simulium arcticum Malloch and S. canadense Hearle (Diptera: Simuliidae) were made in 1971 and 1972 in three streams near Corvallis, Oregon. The purpose of the study was to characterize the biology and population dynamics of larvae, and...

Fishing Effort Response to A Spatial Closure: Rockfish Conservation Area in California

Creator:: Kosaka, Rosemary, Mamula, Aaron, Mason, Janet, and Speir, Cameron
Abstract:: This paper analyzes the effects of spatial closures on the multi-species groundfish trawl fishery in northern and central California. The analysis differentiates between changes in total effort and in the spatial distribution of effort before and after implementation of the closures. We use logbook data on the location and duration...

Measuring Differential Changes in Commercial Fishing Ports: A Shift- Share Analysis of North-Central California

Creator:: Speir, Cameron, Pomeroy, Caroline, Sutinen, Jon, and Thomson, Cynthia
Abstract:: This paper examines differences and changes in fishing activity among individual ports in a multi-species fishery using shift-share analysis. We describe overall trends in the fishing industry in north-central California and examine the extent to which different ports have fared differently. Trends in trips, boats, and revenue indicate that the...

Geographic Concentration in the Northeast U.S. Sea Scallop Fishery

Creator:: Lee, Min-Yang, Speir, Cameron, and Carr-Harris, Andrew
Abstract:: New Bedford’s share of Atlantic sea scallops landings and revenues increased from 44% in 1996 to 67% in 2013. Explanations for industrial agglomerations often focus on the relative importance of natural advantage and economies of scale or scope. We use the absolute and relative Theil indices of disproportionality to examine...

The Economic Geography of Scallop Fishing: Concentration and Competition in the Ocean

Creator:: Lee, Min-Yang, Benjamin, Sharon, Carr-Harris, Andrew, Speir, Cameron, and DePiper, Geret
Abstract:: Geographers and regional scientists have long recognized that "near things are more related than distant things." Ports located far from each other may compete through use of the same fishing grounds. We describe trends in competition in the Northeast U.S Sea Scallop Fishery using a Czekanowski Index over the past...

The Impact of Catch Shares on Fishing Income Diversification and Variation in Annual Revenue

Creator:: Holland, Daniel, Speir, Cameron, Kasperski, Steve, Agar, Juan, Crosson, Scott, Perruso, Larry, Kitts, Andrew, and DePiper, Geret
Abstract:: Many fishermen diversify their income by fishing in more than one fishery which can significantly reduce year-to-year variation in income. However, opportunities to diversify have become more limited as access to fisheries has become more restricted. The implementation of catch share systems could further reduce diversification if those who remain...

Ecosystem Service Values and the Klamath River Dam Removal

Creator:: Kosaka, Rosemary
Abstract:: In February 2010, two agreements were finalized by Federal, State, and Tribal governments and PacifiCorp, a utility company that owns dams on the Klamath River: the Klamath Basin Restoration Agreement (KBRA) and the Klamath Hydroelectric Settlement Agreement (Settlement Agreement). These agreements included provisions that would affect the Klamath River Basin...
