| dc.description |
In May 2006 the Powers Fisheries Ecology Lab in collaboration with National Marine Fisheries Service initiated a nearshore longline survey to investigate the abundance and distribution of coastal sharks in Alabama and Mississippi waters. Ten years of National Marine Fisheries Service bottom longline data indicate substantial differences in species abundance and distribution between the eastern and western Gulf of Mexico, divided roughly at Mobile Bay. These differences may carry important consequences for trophic transfer and food web dynamics between regions. As a result, the goals of this research are 1) to sample east and west of Mobile Bay to quantify any differences in distribution and abundance, 2) to use stable isotope and stomach content data to investigate potential dietary differences between regions. As researchers and resource managers consider multi-species management strategies, data like these are of paramount importance for adequate management of marine resources. |
