SEAwise report on the bycatch mortality risk of potentially endangered and threatened species of fish, seabirds, reptiles and mammals
The SEAwise project works to deliver a fully operational tool that will allow fishers, managers, and policy makers to easily apply Ecosystem Based Fisheries Management (EBFM) in their fisheries and bycatch of protected, endangered and threatened (PET) species is a major concern in EBFM implementatio...

The SEAwise project works to deliver a fully operational tool that will allow fishers, managers, and policy makers to easily apply Ecosystem Based Fisheries Management (EBFM) in their fisheries and bycatch of protected, endangered and threatened (PET) species is a major concern in EBFM implementation. This SEAwise report evaluates the effects of fishing on bycatch of PET species by applying a hierarchical framework that moves from qualitative to quantitative methodologies depending on species vulnerability to bycatch and data availability. By these means, this work identifies current areas of highest bycatch risk across the case studies and assesses the sustainability of bycatch levels on PET populations. The first step of this report consisted of the application of the semi-quantitative Productivity-Susceptibility Analysis (PSA) to a wide range of sensitive species across European waters, including cetaceans, bony and cartilaginous fishes and a single seabird species. PSA measures the risk of a species to over-exploitation by a fishery based on two properties; productivity, defined by the life history characteristics determining the intrinsic rate of population increase, and susceptibility, based on the interactions between population and fishing dynamics.
