Abstract

We conducted a gillnet survey from May through September 2014, at two locations in Charlotte Harbor, Florida: Long Point (LP) and Pine Island (PI). Elasmobranchs and teleosts were sampled using two different methodologies: 1) the same methodology as a previous survey conducted by Mote Marine Laboratory from 1995 to 2004 and in 2013; and 2) the methodology used in the NMFS-coordinated Gulf of Mexico Shark Pupping and Nursery (GULFSPAN) program. The goals of our study were to characterize changes in abundance and species composition of coastal sharks between the two survey periods (1995-2004 vs. 2013-2014); evaluate the potential of the fishery-independent survey to monitor trends in abundance of other fish species found in the area; compare the selectivity of the historical single panel net used by Mote with the selectivity of the multi-panel net used in GULFSPAN projects; and estimate seasonal growth patterns for juvenile blacktip sharks.
