Comparison of two methods to assess fish losses due to depredation by killer whales and sperm whales on demersal longline
combination of socio-economical, ecological and conservation issues. However, estimating the amount of ... indirect methods of assessment of depredated biomass over a 11-year period (from 2003 to 2013), both ... accounting for spatial variations of depredation levels. In the first method, we used fishing data from 6 525 ... longline sets to calculate the difference between Catch Per Unit Effort (CPUE) of non-depredated and ...
