The North Atlantic U.S. groundfish and scallop processing industries are a tale of two fisheries. The groundfish processing industry has suffered a steep, almost continual decline in landings starting in 1984 that resulted in 2014 landings that were only 16% of 1983 landings. US scallop landings increased from 5 million...
Climate change and continued fishing pressure threaten to increase recruitment variability for many stocks globally. Shifts in the inter-annual stability of an exploitable renewable resource may have dramatic consequences for the industries and communities which depend upon them. In this talk, the link between resource volatility and industry structure is...
Ecologists warn that the rapid evolution occurring as a result of high-intensity commercial fishing could have potentially disastrous economic and ecological effects. The evolution of economically relevant life-history traits in fish, which can occur due to the harvesting pressure from commercial fisheries, can irreversibly diminish fisheries yields and ecological services....
Individual transferable quotas (ITQs) have been used in British Columbian fisheries management for more than 25 years. When they were implemented, few restrictions were placed on who could own or lease quota. As a result, many retiring fishermen retain quotas to lease or sell to processors and corporations rather than...
We empirically disentangle the efficiency mechanism of revenue sharing, in which a group of harvesters shares catch and/or revenue among members of a fishery cooperative, by incorporating the influence of social capital. In addition to each of revenue sharing and social capital influencing a fishery independently we hypothesize social capital...
In an environment of limited resources and expanded management expectations, fisheries regulators face hard decisions about how intensively to regulate different stocks. The Fishery Management Councils are required to regulate harvest of all stocks in a sustainable manner, but have discretion on how much regulatory effort to invest in individual...
The for-hire sector plays a significant role in providing recreational fishing opportunities for Atlantic highly migratory species (HMS) such as tuna, billfish, swordfish, and sharks. Because of the high cost of equipment needed to pursue HMS, many saltwater anglers find chartering a for-hire vessel to be the only affordable alternative....
Ecosystem services (ES) represent a way to represent and quantify multiple uses, values as well as connectivity between ecosystem processes and human well-being. Ecosystem-based fisheries management approaches may seek to quantify expected trade-offs in ecosystem services due to actions such as restoration and gear restrictions, or due to changes such...
Fishing impacts biodiversity on multiple levels, potentially resulting in unintended feedbacks to economic performance of the fishery over time. For example, targeting observable traits within a population can impact genetic diversity, targeting populations within a species can impact population diversity, and targeting valuable species can impact biodiversity at the ecosystem...
The potential economic impact of a fully developed mariculture industry in Alaska is not well understood by industry or policy makers. It is also not entirely clear what is needed to move from Alaska’s current micro industry (approximately $500,000 in annual sales) to a fully developed industry. In general, the...
