1. Comparison of two methods to assess fish losses due to depredation by killer whales and sperm whales on demersal longlines

   aimed at providing two indirect methods of assessment of depredated biomass over an 11-year period (2003 ... depredation occurs on fish in the marine environment. This is the case for killer whales (Orcinus orca) and ... to 2013), accounting for spatial variations of depredation levels.
