Abstract

The paper explored a way to identify the priority species for management through a rank-based risk assessment approach. First, an indicator of overlaps with tunas and tuna fishing was established, and then, apply to all fish species to identify a set of Species Group that could interfere with ICCAT tunas fishing, i.e. a pseudo-community for evaluating potential management importance in EBFM. The priority species in order to minimize the potential impact of ICCAT tuna fisheries were examined as an example based on and three criteria: significance of ICCAT tuna fisheries, stock status, and availability evidence of bycatch. The exercise succeeded to identify relatively small number of priority species despite an extreme simplicity of methodology used. Although the evaluation against the existing management scheme could not be conducted due to time constraints, the approach explored seemed to be promising as potential tool to facilitate argument in setting EBFM priorities.
