SUMMARY:Advanced Simulations of Impacts from Large Oil Spills on Six Comme
 rcially Important Fish Stocks in the North Atlantic
DESCRIPTION:Paper\n\nGeir Morten Skeie and Jolynn Carroll (Akvaplan-niva),
  Håvard Gulbrandsen Frøysa (Institute of Marine Research), Achim Randelhof
 f (Akvaplan-niva), Mathias Bockwoldt (The Arctic University of Norway), Da
 niel Howell (Institute of Marine Research), Raymond Nepstad and Ole Jacob 
 Broch (SINTEF), Gro Harlaug Refseth (Akvaplan-niva), and Frode Vikebø (Ins
 titute of Marine Research)\n\nThe SYMBIOSES project has run in three phase
 s over a period of > 10 years, financed by the Norwegian Research Council 
 and a number of operators on the Norwegian Continental Shelf. In this thir
 d phase of the project we apply a high resolution 3-D coupled biological-p
 hysical model that includes a toxic effects module to simulate impacts of 
 large oil spills on the recruitment and subsequent changes in the Spawning
  Stock Biomass (SSB) of six commercially important fish stocks in the Nort
 h Atlantic. The SYMBIOSES model includes species characteristics and annua
 l variations in recruitment and is used to simulate a range of years and s
 pill locations, as well as a range of sensitivity to oil toxicity. \nOil s
 pill simulations of existing producing fields and exploration activities s
 how a maximum 8.8 % larval mortality with a reduction of SSB in a subseque
 nt year of 1.1 %. Results of simulations performed on a set of locations i
 n environmental "hot spots" in areas currently closed to petroleum activit
 y indicate a maximum loss of 56 % of larval and a subsequent reduction of 
 SSB of 18 %. \nThe SYMBIOSES modeling tool extrapolates impacts on individ
 ual fish to the entire population, delivering comparative information for 
 diverse fish species in the North Atlantic. These simulation results provi
 de valuable input to the Management Plans for the Norwegian Continental Sh
 elf and decision support for planning activities, as well as seeking the b
 est options for reducing the impact on fish SSB.\n\nTag: Remediation\n\nSe
