In the quest to limit the bycatch of non-target species, marine protected
areas (MPAs) have been frequently utilized. MPAs are popular with
ecologists and fishery managers because of their relative ease of
administration, habitat protection benefits, and the widespread acceptance
of MPAs as an instrument of choice for the ecosystem...
Spatial closures are a prominent tool for ecosystem-based management in commercial fisheries. The potential benefits of spatial closures in commercial fisheries have been discussed thoroughly in the literature; however, empirical estimates of the potential short-run costs incurred by the commercial fishing industry are relatively scarce. Spatial closures constrain the ability...
After salmon bycatch levels reached record levels in 2006 and 2007 in the
Bering Sea pollock fishery, the North Pacific Fishery Management Council
(NPFMC) began consideration of a hard cap that would close the fishery if
it were reached. The NPFMC asked for input from economists at the
National Marine...
The Alaska non-pollock multi-species catcher processor trawl fishery, referred to as the Amendment 80 fishery since 2008, is an endlessly fascinating subject from the perspective of an economist. A diverse group of companies and vessels, emphasizing different species mixes from a multi-species ecosystem, targets fish across the Eastern Bering Sea,...
We describe the dynamics by which competing harvesters selectively target prime market-sized fish, without internalizing the externality of increasing targeting costs, as the abundance of prime fish decreases. Due to the increasing targeting costs for prime size, harvesters continually target the next-most-desirable size fish, gradually fishing down the size structure...

For every fish species, future potential harvests are impacted by current
catch levels and patterns. Traditionally, managers use regulations on gear
(e.g., mesh size) to control so-called growth overfishing. Such regulations
are likely economically inefficient due to increased search costs and lower
catch rates. Bioeconomic models typically evaluate efficiency for...
