FLR: an open-source framework for the evaluation development of management strategies. – ICES Journal Marine Science, 64: 640–646. The FLR (Fisheries Library R) is a effort directed towards fisheries overall goal to develop common facilitate collaboration within across disciplines (e.g. biological, ecological,...
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...
The 'stock concept' in fisheries science conforms to theoretical assumptions of stock assessment models, including negligible movement across boundaries, relatively homogeneous vital rates, and extensive mixing within areas. Best practices for representing population structure involve 1) interdisciplinary identification delineate spatially discrete populations or more complex structure; 2) boundaries that are aligned with the most plausible 3) spatially-explicit sampling, fleet spatial...
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...
This paper summarizes the lessons learnt for management of small pelagic fish from case study managing international fishery on Bay Biscay anchovy. A constant catch regime ended up with a crash and closure (2005–2009) after series recruitment failures. Precautionary advices had been disregarded due to their inability predict size population during first half year when major takes place. The triggered EU develop long-term plan in 2008. In absence indicator, biological risk was minimized...
Achieving single species maximum sustainable yield (MSY) in complex and dynamic fisheries targeting multiple (mixed fisheries) is challenging because achieving the objective for one may mean missing another. The North Sea mixed are a representative example of an issue that generic across most demersal worldwide, with diversity inducing numerous biological technical interactions. Building on rich knowledge base understanding quantification these interactions, new approaches have emerged....
Snapper and grouper are important fisheries resources, with high commercial value an role in the livelihoods food security of many local communities worldwide. However, status snapper is unknown, particularly small-scale developing countries. The main goals this work to provide overview current trends these resources find alternative sources information that could be used inform fisheries, as well other data-limited fisheries. Several complementary approaches were explored, including...
The Marine Stewardship Council's (MSC) global fisheries certification program plays a crucial role in MSC's Theory of Change by promoting fishing practices that mitigate impacts on ecosystems while supporting sustainable harvesting marine and freshwater fish invertebrates. This paper discusses the Fisheries Standard Review (FSR) process, which aims to keep standard updated reflect evolving management best scientific findings around world. It involved multiple rounds public consultations...
Abstract This manuscript discusses the benefits of having a stock assessment model that is intuitively close to linear model. It creates case for need such models taking into account increase in data availability and expansion requests. We explore ideas around large numbers stocks make easier run more intuitive, so scientists from diverse backgrounds can be involved. show, as an example, developed under European Commission Joint Research Center’s ‘Assessment All’ Initiative (a4a) how it fits...
Abstract This paper explores the possibility of using ensemble modelling paradigm to fully capture assessment uncertainty and improve robustness advice provision. We identify discuss advantages challenges approaches in context scientific advice. There are uncertainties associated with every phase stock process: data collection, model choice, assumptions, interpretation risk, up implementation management Additionally, dynamics fish populations complex, our incomplete understanding those...
Well-designed and robust harvest strategies are a key governance tool to achieve long term sustainability of target stocks. In some fisheries, however, such as those governed by Regional Fisheries Management Organisations (RFMOs), the development adoption can be challenging. Seafood eco-labelling programs, Marine Stewardship Council (MSC), one way incentivising fisheries advocate for control rules (HCRs). Here we illustrate process through which MSC Standard was recently revised guide...
Abandoned, lost or discarded fishing gear, otherwise known as ‘ghost gear’, impacts marine ecosystems in a variety of important ways. The growing recognition these has led to an evolution fisheries management with focus on gear loss avoidance and ghost mitigation. Marine Stewardship Council responded the global challenge through revisions made its Fisheries Standard during recent Review (FSR). certified against will be required explicitly assess manage their impact target stocks, bycatch...

Abstract The current fish stock assessment process in Europe can be very resource- and time-intensive. scientists involved require a particular set of skills, acquired over their career, drawing from biology, ecology, statistics, mathematical modelling, oceanography, fishery policy, computing. There is focus on producing single “best” model, but as science advances, there are clear needs to address range hypotheses uncertainties, large-scale issues such climate change specific ones, high...
Abstract Many of the world's fisheries are unassessed, with little information about population status or risk overfishing. Unassessed particularly predominant in developing countries and small‐scale fisheries, where they important for food security. Several catch‐only methods based on time series fishery catch commonly available life‐history traits have been developed to estimate stock (defined as biomass relative at maximum sustainable yield: B/ B MSY ). While their performance has...
Fisheries may volunteer to be audited against the Marine Stewardship Council's Standard achieve eco-certification for their seafood products. The uses a hierarchical scoring structure with four nested levels: (i) three principles, (ii) nine components, (iii) 27–29 performance indicators, and (iv) 78–93 issues each evaluated at up guideposts. Changes this revise requirements can affect resulting scores therefore certification outcomes. As part of MSC's policy development process, we modelled...
Estimating fish stock status is very challenging given the many sources and high levels of uncertainty surrounding biological processes (e.g. natural variability in demographic rates), model selection choosing growth or assessment models) parameter estimation. Incorporating multiple a allows advice to better account for risks associated with proposed management options, promoting decisions that are more robust such uncertainty. However, typical only reports fit variance estimated parameters,...
Abstract Fisheries management typically aims at controlling exploitation rate (e.g., Fbar) to ensure sustainable levels of stock size in accordance with established reference points F MSY , B ). Population selectivity (“selectivity” hereafter), that is the distribution fishing mortality over different demographic components an exploited fish stock, also important because it affects both Maximum Sustainable Yield (MSY) and as well resilience overfishing. The development appropriate metric...
Effective fisheries management is reliant on the availability of accurate information, which also provides evidence base for certification against sustainability standards. In this paper we describe process developing ambitious new requirements needed to demonstrate a fishery's performance Marine Stewardship Council Fisheries Standard. A novel Evidence Requirements Framework was developed evaluate information system determine accuracy it produces. This framework ensures that MSC underpinned...
