Abstract:
Many sharks and some rays are known for undertaking long-distance seasonal migrations, which complicate efforts to manage fisheries for these species. However, despite ranging across entire coastlines and even ocean basins, many elasmobranch species show fidelity to specific areas of particular importance such as nurseries, refuges, and foraging grounds that are disproportionately important to their survival and population dynamics. Identification of these essential habitats can allow for more efficient targeting of spatial conservation and management efforts such as seasonal fishery closures and marine protected areas. Telemetry methods show great promise for defining the location, spatial extent, and seasonal timing of these important areas and for predicting the effects of anthropogenic impacts and large-scale environmental changes on essential habitats. In this presentation I will show how acoustic telemetry combined with behavioral state-space modeling and environmental data can be used to identify essential habitats for highly migratory elasmobranchs and the ecological factors that may drive the selection of these habitats. Example telemetry studies will focus on Cownose Rays (Rhinoptera bonasus), Sandbar Sharks (Carcharhinus plumbeus), and Dusky Sharks (Carcharhinus obscurus) in the U.S. Mid-Atlantic region. The results of these efforts showed that telemetry data in combination with other data sources can provide information that is both relevant to specific fishery management policies while also improving our understanding of habitat use and movement ecology in migratory elasmobranchs.
