SEAwise report on effects of spatial management measures suggested in SEAwise to safeguard species, habitats and choke species on fisheries selectivity and fuel cost Open
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. This SEAwise report investigated the available tools for predicting th…

Workshop to Update and Assess Trade-Offs Between the Impact of Fisheries on Seafloor Habitats and Their Landings and Economic Performance (WKD6ASSESS) Open
WKD6ASSESS aimed to provide an updated assessment of bottom trawl impact versus financial gain in all European waters, for the status quo and under various future management scenarios. In this, the latest developments made in various ICES …

An empirical review of ICES reference points Open
The International Council for the Exploration of the Sea (ICES) has provided scientific stock advice based on reference points to manage fisheries in the North Atlantic Ocean and adjacent seas for decades. ICES advice integrates the precau…

Numbers or mass? Comparison of two theoretically different stage-based stock assessment models and their ability to model simulated and real-life stocks Open
Stage-based assessment models are a type of fisheries stock assessment model that offer an alternative middle ground between aggregate and compositional models. We compare the capabilities of two theoretically different stage-based assessm…

Moving reference point goalposts and implications for fisheries sustainability Open
For many environmental indicators, the sustainable status can change because of changes in either the monitored state or the policy goal. Fisheries provide an intensively monitored setting to investigate the relative impacts of such change…

Estimating growth parameters and growth variability from length frequency data using hierarchical mixture models Open
Analysis of length frequency distributions from surveys is one well-known method for obtaining growth parameter estimates where direct age estimates are not available. We present a likelihood-based procedure that uses mixture models and th…
