Abstract.—Declines in Atlantic sturgeon Acipenser oxyrinchus abundance in the
Declines in Atlantic sturgeon Acipenser oxyrinchus abundance in the early 1990s led the Atlantic ... more Declines in Atlantic sturgeon Acipenser oxyrinchus abundance in the early 1990s led the Atlantic States Marine Fisheries Commission (ASMFC) to prepare a mandatory fishery management plan. The principal management measures are fishery closure, bycatch assessment, and bycatch reduction in other ASMFC-managed fisher- ies (i.e., American shad Alosa sapidissima). To better understand Atlantic sturgeon geographic distribution and habitat use, as well as risk of bycatch, we examined off- shore distribution of Atlantic sturgeon based on incidental captures in winter tagging cruises conducted off the coasts of Virginia and North Carolina, including in and near extensive sand shoals adjacent to Oregon Inlet and Cape Hatteras. From 1988 to 2006, 146 juvenile Atlantic sturgeon were captured by bottom trawling in depths from 9.1 to 21.3 m. Numbers of Atlantic sturgeon captured and tagged in a given year ranged from 0 (1993, 1995) to 29 (2006). Atlantic sturgeon were encountered in 4.2% of tows, ...

Total lengths of captured Atlantic sturgeon ranged from 577 to 1,517 mm (mean of 967 mm), suggesting that most fish were juveniles. Limited tag returns and genetic data suggest that fish wintering off North Carolina constitute a mixed stock. Information about their distribution and habitat utilization should benefit fishery managers seeking to reduce bycatch and protect key habitats.

American eels spawn in the Atlantic Ocean, and their offspring use rivers from maritime Canada to northern South America as nursery areas. They were historically largely eliminated from the upper Roanoke River Basin due to flood control and hydropower dam construction, consequently reducing upstream native fish diversity as well as eel production. As part of the Federal Energy Regulatory Commission relicensing process with Dominion/North Carolina Power, the National Marine Fisheries Service issued a Section 18 fishway prescription requiring safe, timely and effective passage be provided for eels reaching the Dominion dams. We sampled eels in the river’s bypassed reach and in the tailrace below Roanoke Rapids Dam from 2005 – 2008 to assess the abundance and distribution of eels below the dam. Large collections in conventional elver traps within the bypassed reach documented seasonal and horizontal distribution patterns...

We estimated a 17-year time series of annual survival and fishing mortality (F) rates for striped bass (.711 mm) tagged during winter trawl studies (1988-2004) off the coasts of North Carolina and Virginia. The geographic and temporal distributions of tag recoveries were consistent with published patterns of striped bass migration and indicated that this southern overwintering aggregate of striped bass is composed of mixed stocks. Incremental increases in bias-adjusted annual fishing mortality rates (from 0.00-0.26) and decreases in the proportion of fish released alive (from 0.762-0.198) coincided with periods of regulatory change during the 17-year time frame. Our estimates of F fall below the current management triggers and should be considered along with other estimates of F within the striped bass management process.
