Abstract Every year, millions of pots and traps are lost in crustacean fisheries around the world. Derelict fishing gear has been found to produce several harmful environmental ecological effects, however socioeconomic consequences have investigated less frequently. We analyze economic effects a substantial derelict pot removal program largest estuary United States, Chesapeake Bay. By combining spatially resolved data on removals with commercial blue crab ( Callinectes sapidus ) harvests...

Abstract Diversification within and outside of small-scale fisheries (SSF) is a common strategy to stabilize revenues increase resilience following disturbances. Using SSF in Virginia, USA as case study, Herfindahl–Hirschman Indices (HHIs) were used characterize individual fleet levels income diversification, while generalized linear mixed models examine drivers diversification behavior. HHI values indicate that fishers tended exhibit specialized More diversified have less interannual...

Coastal Virginia, a region with economic and strategic significance at the state national level, has been experiencing highest sea-level rise (SLR) on Atlantic coast of United States. This accompanied by variety climate hazards such as flooding more frequent storms, initiating adaptation planning decision-making multiple governance levels. A spatial understanding risk its associations socioeconomic vulnerabilities raises essential questions about underlying roots can help local governments...

In 2009, Rhode Island implemented a pilot catch share program around summer flounder, or fluke, state-managed species that is jointly harvested with the Northeast Multispecies groundfish complex. A sector was given fluke allocation to land when they wished, while rest of fleet managed through sub-seasonal total harvest caps and daily trip limits. Sector members avoided landings during seasonal derbies, instead shifting post-derby closures in general fishery, price higher. However, also...

Even under current sea level conditions, many communities are working to protect their coastlines against flooding and shoreline erosion. Coastal often shorelines excessive erosion by using armoring techniques (e.g., bulkheads, riprap). Yet hardened structures reduce of the natural adaptive mechanisms present in coastal ecosystems sustainability system. In contrast, nature-based features living shorelines) can better properties from storm damage while also having potential adapt new...

The eastern oyster once provided major societal and ecosystem benefits, but these benefits have been threatened in recent years by declines harvests. In many areas, recovery of aquaculture faces significant opposition spatial constraints limiting its ability to meet expectations regarding future food needs provision services. Virginia, has begun rebound, concurrent with an increase subaqueous leased areas (over 130,000 acres grounds are currently leased). Though private leases must theory be...

Abstract Competing pressures imposed by climate-related warming and offshore development have created a need for quantitative approaches that anticipate fisheries responses to these challenges. This study used spatially explicit, ecological-economic agent-based model integrating dynamics associated with Atlantic surfclam stock biology, decision-making behavior of fishing vessel captains, fleet simulate biomass, catch, effort landings. Simulations were implemented using contemporary...

Trends in Atlantic surfclam (Spisula solidissima) population demographic parameters were analyzed using age and length observations obtained from NOAA stock surveys conducted the 1980s to 2010s six regions distributed along Middle Bight (MAB) continental shelf. asymptotic specific growth rate estimated for each survey region decade von Bertalanffy function.

ABSTRACT The Atlantic surfclam, Spisula solidissima supports a lucrative commercial fishery in the Mid‐Atlantic Bight (MAB) worth roughly $30 million revenue per year. Rapid climate change is expected to modify geographic range of with consequences for surfclam fishery. This study evaluated fishery‐based indicators projected from 2020 through 2095 based on anticipated changes and biomass using Spatially Explicit, agent‐based Fisheries Economics Simulator (SEFES). Simulations generally showed...

Abstract In 2010, management of New England multispecies groundfish transitioned from input restrictions on harvester effort to collective rights-based management. Faced with a large reduction in harvesting days, 432 active vessels, representing 98% historical landings, joined one the 17 sectors allocated catch shares. The incentives presented under sector management, combined regulations several separately managed, revenue-important species, led changes harvest strategies and timing...

Abstract The Atlantic surfclam Spisula solidissima fishery, which spans the U.S. Northeast continental shelf, is among most exposed to offshore wind energy development impacts because of overlap fishing grounds with lease areas, hydraulic dredges used by vessels, and location vessel home ports relative grounds. federal assessment survey conducted using a commercial in locations that development. Once turbines, cables, scour protection are installed, operations within areas may be curtailed...

Abstract Rising water temperatures along the northeastern U.S. continental shelf have resulted in an offshore range shift of Atlantic surfclam Spisula solidissima to waters still occupied by ocean quahogs Arctica islandica . Fishers presently are prohibited from landing both surfclams and same catch, thus limiting fishing locations where target species can be sorted on deck. Wind energy development around grounds will further restrict fishery. A spatially explicit model fishery (Spatially...

Abstract The Atlantic Bluefin Tuna Thunnus thynnus is the target of a recreational fishery along U.S. East Coast that thought to be considerable economic value. In some years, landings have exceeded sector's annual subquota due changes in fish availability, limited predictability angler effort, and difficulties real‐time monitoring catch. Understanding drivers behavior critical for predicting how effort harvest may vary as function changing regulations, or costs. To investigate decision...

Observed production sets in multispecies fisheries are affected by regulatory incentives influencing spatiotemporal fishing decisions. Rights-based output controls can promote selective fishing; however, this ability may be limited and insufficient achieving full utilization of catch quotas. We measure selectivity for bottom trawlers catching federally regulated groundfish the Gulf Maine Georges Bank before after introduction rights-based controls. Directional distance functions applied to...

Fisheries economists typically assume recreational anglers make decisions that maximize individual angler utility, which may depend on fishery and regulatory conditions. Under this framework, changes in regulations can lead to target species substitution by response shifts expectations of trip utility. A stated preference survey was developed distributed cobia (Rachycentron canadum) Virginia explore the effects change decision-making, targeting, resulting economic outcomes. The included a...

Pop-up satellite archival tags (PSATs) are a valuable tool for estimating mortality of pelagic fishes released from commercial and recreational fishing gears. However, the high cost PSATs limits sample sizes, resulting in low-precision post-release estimates with little management applicability. We evaluate performance lower-cost PSAT designed to enable large-scale studies. The tag uses solar rather than battery power, does not include depth sensor, transmits daily summaries light...
