The Large Pelagics Lab at SWFSC conduct studies on several aspects of the lives of sharks in the North Pacific Ocean. Shark Research studies include investigations on biology, physiology, ecology and migration as well as distribution and abundance, population genetic structure, and fishery interactions. The researchers in the Large Pelagics Lab at Southwest Fisheries Science Center conduct research mandated under the Highly Migratory Species Fishery Management PlanThe previous link is a link to Non-Federal government web site.

Species we directly research are the blue shark (Prionace glauca), shortfin mako shark (Isurus oxyrinchus), and thresher sharks: thresher (Alopias vulpinus), pelagic thresher (Alopias pelagicus), and bigeye thresher (Alopias superciliosus). Under the FMP, we also opportunistically monitor other species, including great white sharks (Carcharodon carcharias), basking sharks (Cetorhinus maximus), and hammerhead sharks (Sphyrna spp.) if they are in the area.
