HunsickerMaryCEOASPotentialTopDown(VOR).pdf

Creator:: Hunsicker, Mary E., Olson, Robert J., Essington, Timothy E., Maunder, Mark N., Duffy, Leanne M., and Kitchell, James F.
Abstract:: The ecological consequences of widespread fisheries-induced reductions of large pelagic predators are not fully understood. Tropical tunas are considered a main component of apex predator guilds that include sharks and billfishes, and thus may seem unsusceptible to secondary effects of fishing top predators. However, intra-guild predation can occur because of...

Creator:: Melnychuk, Michael C., Essington, Timothy E., Branch, Trevor A., Heppell, Selina S., Jensen, Olaf P., Link, Jason S., Martell, Steven J. D., Parma, Ana M., and Smith, Anthony D. M.
Abstract:: Individual quota (IQ) management systems in commercial marine fisheries are highly diverse, differing in the security, durability and exclusivity of the harvesting privilege and the transferability of quota units. This diversity in the degree of harvest rights may influence the effectiveness of IQ fisheries to meet management objectives. We conducted...

Can catch share fisheries better track management targets?

Creator:: Melnychuk, Michael C., Essington, Timothy E., Branch, Trevor A., Heppell, Selina S., Jensen, Olaf P., Link, Jason S., Martell, Steven J. D., Parma, Ana M., Pope, John G., and Smith, Anthony D. M.
Abstract:: Fisheries management based on catch shares – divisions of annual fleet-wide quotas among individuals or groups – has been strongly supported for their economic benefits, but biological consequences have not been rigorously quantified. We used a global meta-analysis of 345 stocks to assess whether fisheries under catch shares were more...

Catch shares, fisheries, and ecological stewardship: a comparative analysis of resource responses to a rights-based policy instrument

Abstract:: Rights-based approaches are potentially promising tools to meet conservation objectives in natural resource management. Here, we evaluated how population status and fishery production respond to catch shares, a rights-based policy instrument in fisheries whereby participants are granted a right to harvest a fraction of the allowable catch. By analyzing time...
