Abstract:

\n

Incidental capture in non-target c ommercial and recreational fisheries can contribute to mortality of prohib ited dusky (Carcharhinus obscurus)\, sand tiger (Carcharias taurus)\, and white (Carcharodon carcharias) sharks. Slow growth\, late maturity\, low r eproductive output\, and prolonged recovery make these species especially sensitive to even modest levels of fishing-related mortality\, particularl y when mortality occurs during immature life stages or through delayed pos t-release effects. Fishery interactions\, capture stress\, and post-releas e outcomes will be examined across the Northeast U.S. by integrating comme rcial fishery observer data\, blood-based indicators of capture stress\, a nd satellite telemetry. Fleetwide bycatch and at-vessel mortality in North east and Mid-Atlantic commercial gillnet and trawl fisheries are quantifie d using long-term observer records (Chapter 1). The physiological effects of recreational rod-and-reel capture in the New York Bight will be evaluat ed using blood-based indicators of capture stress and associated capture m etadata (Chapter 2)\, and post-release behavior\, recovery\, and apparent survival after recreational capture will be evaluated using satellite tele metry\, with emphasis on short-term recovery trajectories\, delayed mortal ity\, and variability in vertical behavior after release (Chapter 3). Toge ther\, these chapters are intended to provide a more complete understandin g of how incidental capture affects prohibited sharks by integrating fishe ry interactions\, capture stress\, and post-release outcomes across commer cial and recreational fisheries\, while generating information directly re levant to mortality estimation\, handling guidance\, and conservation mana gement in the Northeast U.S.
