Description:

Some degree of areal overlap is known to occur among the four stocks of bottlenose dolphins (Tursiops truncatus) that inhabit North Carolina during all or part of year. This overlap poses challenges to estimating abundance of each stock and assigning bycatch in commercial fisheries to a particular stock. Overcoming these challenges is especially crucial for the NNCES (Northern NC Estuarine System) stock, for which the small estimated population size may make a single incidence of bycatch greater than the population can sustain. As a first step to determining if the NNCES stock can be distinguished genetically from other stocks, a focused field project was conducted during the summer of 2010 to collect biopsy samples from bottlenose dolphins in Pamlico Sound when the NNCES is isolated from the other stocks. We conducted 23 surveys covering 1854.6 km during five weeks of sampling effort, encountering 44 dolphin groups containing 824 individual dolphins. During these encounters, we took over 4230 photographs and collected 41 biopsy samples.
