SEAFWA 2015 has ended
Welcome to the technical sessions schedule for the 2015 SEAFWA Annual Meeting.

NEW THIS YEAR!
The technical schedule is capable of being sorted by date (i.e, Monday, Nov. 2), track (i.e. Wildlife Technical Sessions), or session (i.e. Wildlife Session #1). You can also search for a presentation title (i.e. Changing Landscapes by Coalition), key term (i.e. striped bass), or presenter last name (i.e. Weaver). The sort and search functions can be found on the navigation panel on the right side of this page. If you hover over the "Schedule" button, you’ll also see different schedule view options (i.e. Grid or Simple). Try selecting each of them to see which view you prefer.

The New River Crayfish, (Cambarus (Hiaticambarus) chasmodactylus), was first collected in 1890 from the New River, in Wytheville, VA; it was later described from the East Fork of the Greenbrier River, Pocahontas County, West Virginia. The New River Crayfish, historical distribution was limited to the New River Basin from the Greenbrier River sub-basin in West Virginia, upstream to the headwaters of the South Fork of the New River in North Carolina. A complete range-wide assessment was coordinated with various organizations and agencies from West Virginia, Virginia, and North Carolina. General species information was summarized including species description, taxonomy, habitat use, life history, and current distribution. All historical and recent collections were combined and spatially displayed using GIS software. The New River Crayfish was collected in three 8-digit HUCS and 14 counties with the majority of occurrences in the Upper New and Greenbrier sub-basins. It was present in 92, 12-digit HUCS and in ~100 different streams throughout the range. Information that pertained to the five factors for federal listing were addressed. Given the wide distribution of this species in the New River basin, the high abundances where it occurs, the lack of any major threats, and the various protections in place for the streams in the New River basin, the New River Crayfish population is considered stable and does not warrant federal listing at this time.
