Abstract

Towed, underwater videography was used to map and characterize the extent of oyster bottom in the upper Piscataqua River, Sturgeon Creek, and Spruce Creek. Georeferenced video imagery was obtained on five different days in summer and fall 2008. Significant shell bottom (with live oysters in most areas) was found only in the upper Piscataqua River in two areas: (1) the general location of the previously mapped (2003) upper Piscataqua River reef, and (2) in the Piscataqua River at the mouth of Sturgeon Creek. The Sturgeon Creek reef was classified into low and high density shell which covered a total area of 15.6 acres (~63,000 m2). Recommendations included additional survey work in the lower Salmon Falls and Cocheco Rivers, and Spruce Creek.
