Shark Working Group
The ISC Shark Working Group (SHARKWG) is made up of scientists from ISC Member nations and observers. The SHARKWG meets regularly to assess and analyze fishery data and other information, including trends in population abundance and developments in fisheries; to determine the status of the stocks of key shark species captured in the North Pacific; and to develop scientific advice concerning conservation needs. The SHARKWG also promotes cooperative and collaborative research among members by developing proposals for international research programs and coordinating, to the extent possible, national programs addressing research needs for these shark species.
The two species of greatest priority to the SHARKWG based on their distribution with respect to North Pacific fisheries and high relative encounter rates are the blue (Prionace glauca) and shortfin mako (Isurus oxyrinchus) sharks. The SHARKWG has begun preparations for a North Pacific blue shark stock assessment to be completed by July 2013, and plans to conduct a North Pacific shortfin mako shark assessment by July 2014. The SHARKWG monitors ongoing research and fishery activities related to other shark species of interest to the ISC, including bigeye thresher (Alopias superciliosus), pelagic thresher (A. pelagicus), common thresher (A. vulpinus), oceanic whitetip shark (Carcharhinus longimanus), silky shark (C. falciformis), hammerhead sharks (Sphyrna spp.), longfin mako (I. paucus), salmon shark (Lamna ditropis), and crocodile shark (Pseudocarcharias kamoharai).
