Economists have long argued that a fishery that maximizes its economic potential usually will also satisfy its conservation objectives. Recently, maximum economic yield (MEY) has been identified as a primary management objective for Australian fisheries and is under consideration elsewhere. However, first attempts at estimating MEY as an actual management target for a real fishery (rather than ...

The stocks of principal groundfish species off New England have collapsed, creating economic hardship and dislocation in fishing communities from Rhode Island to Maine. In this article we analyze the causes of this collapse using the “ratchet effect” described by Ludwig, Hilborn, and Walters (1993) as a framework. According to Ludwig, Hilborn, and Walters, powerful economic and political intere...

Accepted on April 21, 2005. Cabra Corral reservoir is located in Salta Province and is the largest man-made lake in northern Argentina. As other reservoirs located in this area, it was stocked with pejerrey (Od...

Oyster populations in Virginia’s waters of Chesapeake Bay were lightly exploited until the early 1800s, when industrial fishery vessels first arrived, driven south from New England due to the collapse of northeastern oyster fisheries. Early signs of overexploitation and habitat degradation were evident by the 1850s. The public fishery, where oyster fishers harvest on state-owned bottom, rapidly...

Marine no-take reserves, where fishing and other extractive activities are prohibited, have well-established conservation benefits [1], yet their impacts on fisheries remains contentious [2-4]. For fishery species, reserves are often implemented alongside more conventional harvest strategies, including catch and size limits [2, 5]. However, catch and fish abundances observed post-intervention a...

The evaluation of a range of fixed-effort scenarios (undertaken as part of the recently completed project " Development of an operating model and evaluation of harvest strategies for the Eastern Tuna and Billfish Fishery ") provided guidance on identifying an appropriate initial Total Allowable Effort (TAE) for the longline fleet in the ETBF. However, ideally, any harvest strategy adopted for t...

—We conducted a socioeconomic survey and review of existing biological data in an integrated evaluation of current and hypothetical fishery regulations on crappies Pomoxis spp. in Sardis Lake, Mississippi. The objectives of this study were to (1) assess angler acceptance of current and hypothetical harvest restrictions, (2) determine the recreational value of the crappie fishery to its particip...

The spatial, multi-species nature of coral reef fisheries makes them notoriously difficult to manage. We have developed a simulation modeling approach to examine the effect of management options on the recreationally important tourist destination of Ningaloo Reef in Western Australia where a recreational fishery targets Spangled Emperor (Lethrinus nebulosus). The approach brings a broad range o...

(5) How the establishment of the experimental population may contribute to recovery of the UC spring-run Chinook salmon ESU as a whole; (6) The extent to which the experimental population would be affected by current or future Federal, state, or private actions within or adjacent to the experimental population area; (7) Current programs within the experimental population area that protect fish ...
