  • Characterization of the California Live Bait Fishery

    Creator:
    Hilger, James
    Abstract:
    Conservation and management of North American West Coast fisheries encompass a broad array of issues including the economic, spatial, and temporal relations between the coastal pelagic species live bait fishery and the highly migratory species recreational fishery. For the better part the century, the live bait fishery has supplied live...

  • Demand Heterogeneity for Southern California Sportfishing Trips

    Creator:
    Hilger, James
    Abstract:
    This study estimates the demand for saltwater recreational angling trips within the Southern California Commercial Passenger Fishing Vessel (CPFV) fishery. The CPFV fishery provides a variety of trip types to support recreational anglers targeting several species including, tuna, rockfish, yellowtail, and shark. Trips vary by fishing location, by length of...

  • A Multivariate Poisson Approach to Estimating Target Catch and Bycatch Production

    Creator:
    Hilger, James and Stohs, Stephen
    Abstract:
    This paper develops a count data model of target species and bycatch production for an arbitrary number of species that handles correlation between species and over time. The model is applied to a large observer dataset for fishing trips taken from 1990 to 2008 for roughly 150 vessels participating in...

  • Wall Street Or Pacific Stocks? An Analysis of the Historical Drivers of Sportfishing Demand

    Creator:
    Hilger, James and Janofsky, Eric
    Abstract:
    Recent aggregate models of recreational participation have largely focused on demand systems and choice models utilizing cross sectional data. While these strategies may be advantageous for the estimation of welfare measures, they have left unexplored the relationship between recreation participation and general temporal economic trends. This research shifts its focus...

  • Hitting Capacity: Implications for the Valuation of Outdoor Recreation

    Creator:
    Hilger, James and Steiner, Christopher
    Abstract:
    Choices are often limited as the most popular alternatives reach capacity and sell out; thereafter, selection is over less preferred choices. In the context of nonmarket goods, willingness to pay (WTP) welfare measures provide an estimate of the value of characteristics – often calculated through the modeling of preferences using...

  • The Impact of Regulation: A case study of the Leatherback Turtle Conservation Area Closure and the California Drift Gill Net fishery

    Creator:
    Roll, Kristin and Hilger, James
    Abstract:
    Fishery management actions focused on the conservation of non-target species may impact the productivity of fisheries in terms of target species. This article studies California’s drift gillnet swordfish (Xiphias gladius) fishery and investigates the impact of a recent regulatory measure aimed to protect leatherback turtles. A parametric approach is used...

  • Angler Spending on Fishing-Related Durable Goods: Results from the 2014 Durable Good Expenditure Survey

    Creator:
    Lovell, Sabrina, Hilger, James, and Steinback, Scott
    Abstract:
    Purchases made by marine recreational anglers are an important source of economic activity in coastal areas around the United States. In recognition of the economic contributions anglers make to coastal state economies, NOAA Fisheries conducts surveys every three to five years in order to gather data on expenditures made by...

  • Cost-Benefit Analysis of DGN Swordfish Time-Area Closure

    Creator:
    Squires, Dale, Sun, Chin-Hwa, Hilger, James, Chan, Valerie, Helvey, Mark, Herrick, Samuel Jr., Stohs, Stephen, and Segerson, Kathleen
    Abstract:
    Unilateral conservation of a transboundary resources, notably bycatch species, can lead to production, trade, and conservation leakages, losses in net benefits to society, and, paradoxically, increased rather than the intended decline biodiversity loss. A 2001 time-area closure of a key fishing area for the California-Oregon drift gillnet fleet harvesting swordfish...

  • Studies toward the synthesis of halichlorine and pinnaic acid

    Creator:
    Korf, Eric A.
    Abstract:
    Three approaches toward the core of halichlorine and pinnaic acid are described. The first approach entails a racemic transannular nitrone-olefin [3+2] cycloaddition from nitrone 238. Construction of the nitrone 238 began with aldehyde 241. Another key feature in this route involved a ring-closing metathesis for the formation of a 14-membered...

    Schwartz, Keith D.
    Abstract:
    Studies towards the total synthesis of (+)-Phomactin A (1), D (6), and G (9), fungal metabolites with unique molecular architecture and pronounced biological activity, are described. These studies resulted in the synthesis of advanced intermediates 354 and 356, which contain all of the carbon atoms of 1, 6 and 9....
