Dynamic ocean management, or management that uses near real-time data to guide the spatial distribution of commercial activities, is an emerging approach balance resource use and conservation. Employing a wide range types, dynamic can be used meet multiple objectives—for example, managing target quota, bycatch reduction, reducing interactions with species conservation concern. Here, we present several prominent examples highlight utility, achievements, challenges, potential this approach....
Abstract Designing effective bycatch mitigation programmes requires an understanding of the life histories target and non-target species, interactions fish fishing gear, effects spatial temporal shifts in effort, socio-economic impacts to fishery, incentives fishery participants. The measures (including gear modification, time/area closures, quotas caps, incentive programs, fleet communication programs) have been evaluated with respect reducing discards. Less attention has focused on...
ABSTRACT Bycatch of Yellowtail Flounder in the U.S. Sea Scallop Fishery is a constraint to achieving optimum yield scallops. Between 2000 and 2009, in-season bycatch closures prime scallop grounds resulted economic losses over US$100 million. To address this constraint, we collaborated with fishing industry implement avoidance program Nantucket Lightship harvest area 2010. Vessels shared near real-time location information about amounts during activities. We compiled information, identified...
Despite the global scale of gillnet bycatch, universal measures that effectively reduce bycatch seabirds in gillnets have not been found. Bycatch coastal fisheries is an ongoing threat for several seabird species. Strategies to were evaluated, focusing on effectiveness time-area fishing restrictions and gear-switching meet conservation objectives, ensure fisher acceptance, avoid unintended consequences. A review case studies showed variations spatial temporal distributions target non-target...
A video survey was conducted from August 10–14, 2009, to estimate sea scallop density, abundance, and size distribution on Platts Bank, Fippennies Ledge, Jeffreys Cashes Ledge in the central Gulf of Maine. Of 298 km2 surveyed, 134 (45%) had scallops present. Scallop density estimated using only stations containing at least 1 scallop. High densities small occurred all but where no were observed. Densities ranged 1.56 scallops/m2 4.70 equaling an abundance 470 million scallops. Less than 1%...
Many commercial fisheries face bycatch challenges.Avoiding non-target species while maximizing harvest of target may require fishing differently across seasons and years, so the ability to predict occurrence is important for efficient sustainable operations.We demonstrate a potential application predictions in Atlantic sea scallop (Placopecten magellanicus) fishery.Catch data from survey were used develop models yellowtail flounder (Limanda ferruginea) fishery response environmental...
Abstract Objective The effectiveness of bycatch avoidance programs relies on changes in fishing behavior response to spatiotemporal information patterns. A voluntary program the U.S. sea scallop Placopecten magellanicus fishery designed prevent triggering allocation Yellowtail Flounder Limanda ferruginea was implemented and maintained concurrently with other management measures. Detecting relative for mitigation presents an analytical challenge. Methods We evaluated over course 4 years based...
