Abstract An essential prerequisite of a sustainable fisheries management is the matching biologically relevant processes and action. In assessment, fish stocks are fundamental biological unit, but reasoning for operational unit often indistinct mismatches between biology action frequently occur. Despite plethora population genetic data on marine fishes, to date little or no use made information, despite fact that detection differentiation may indicate reproductively distinct populations....
Abstract Recent advances in the application of stock identification methods have revealed inconsistencies between spatial structure biological populations and definition units used assessment management. From a fisheries management perspective, stocks are typically assumed to be discrete with homogeneous vital rates that can exploited independently each other. However, unit assumption is often violated leading mismatches bias impede sustainable The primary ecological concern potential for...
Abstract Marine ecosystem-based management (EBM) is recognized as the best practice for managing multiple ocean-use sectors, explicitly addressing tradeoffs among them. However, implementation perceived challenging and often slow. A poll of over 150 international EBM experts revealed progress, challenges, solutions in worldwide. Subsequent follow-up discussions with 40 these identified remaining impediments to further EBM: governance; stakeholder engagement; support; uncertainty about...

Abstract The exploitation status of marine fisheries stocks worldwide is critical importance for food security, ecosystem conservation, and fishery sustainability. Applying a suite data‐limited methods to global catch data, combined through an ensemble modeling approach, we provide quantitative estimates 785 fish stocks. Fifty‐three percent (414 stocks) are below B MSY these, 265 estimated be 80% the level. While 149 above conventionally considered “fully exploited,” staying at this level...
Abstract In a changing climate, there is an imperative to build coupled social‐ecological systems—including fisheries—that can withstand or adapt climate stressors. Although resilience theory identifies system attributes that supposedly confer resilience, these have rarely been clearly defined, mechanistically explained, nor tested and applied inform fisheries governance. Here, we develop apply comprehensive framework examine fishery systems across (a) ecological, (b) socio‐economic (c)...
In recent decades, scientists and practitioners have increasingly focused on identifying codifying the best ways to manage activities in marine systems, leading development implementation of concepts such as social-ecological systems approach, ecosystem-based management, integrated spatial planning, participatory co-management, precautionary approach. To date, these appear separate entities: they parallel literature streams; been applied most often individually attempts improve governance...
Abstract Multispecies models have existed in a fisheries context since at least the 1970s, but despite much exploration, advancement, and consideration of multispecies models, there remain limited examples their operational use fishery management. Given that species fleet interactions are inherently problems push towards ecosystem-based management, lack more regular is both surprising compelling. We identify impediments hampering provide recommendations to address those impediments. These...

Abstract The World Conference on Stock Assessment Methods (July 2013) included a workshop testing assessment methods through simulations. exercise was made up of two steps applied to datasets from 14 representative fish stocks around the world. Step 1 involved applying stock assessments with varying degrees effort dedicated optimizing fit. 2 subset and characteristics given model fits being used generate pseudo-data error. These were then provided modellers consistency checks within...
Abstract Fishery managers must often reconcile conflicting estimates of population status and trend. Superensemble models, commonly used in climate weather forecasting, may provide an effective solution. This approach uses predictions from multiple models as covariates additional “superensemble” model fitted to known data. We evaluated the potential for ensemble averages superensemble (ensemble methods) improve trend fisheries. fit four widely applicable data‐limited that estimate stock...
Abstract This article considers the approach taken by ICES to integrated ecosystem assessments (IEAs) in context of wider evolution IEAs and science/policy landscape within region. It looks forward challenges facing development IEAs, specifically those scoping for objectives, participatory engagement, developing indicators targets, risk analysis, creating tools evaluate management measures marine anthropogenic activities. concludes that expectations implementation will take an ordered,...
Abstract The inter‐annual variability in year class strength (1976–2000) of North Sea herring ( Clupea harengus ) was investigated using Paulik diagrams based on survey data and Virtual Population Analysis. life cycle split into five stages: spawning stock biomass (SSB), egg production, larvae, fish with 0 winter rings the otolith (0‐wr), 1‐wr 2‐wr. Surveys were used as indices analysis revealed relationships between stages. In 80% years, reflected SSB. Poorer than expected classes...

Despite recent evidence for sub-stock structuring, North Sea cod are assessed as a single unit. As consequence, knowledge of trends is poor. In particular, there no evaluations which spawning grounds active. Here we report results from the first ichthyoplankton survey to cover whole Sea. Also, this survey, conducted in 2004, was make extensive use DNA-based molecular methods unambiguously identify early developmental stage eggs.
