Management Strategy Evaluation (MSE) is a decision-support tool for fisheries management.MSE uses closed-loop simulation to evaluate the long-term performance of management strategies with respect societal goals like sustainability and profits (Punt et al., 2014 ; Figure 1;Smith, 1994).Management are pre-defined decision rules that can dynamically adjust advice given an estimate population status.In addition specifying actions, may specify how stock assessment model configured determine size status (Sainsbury 2000).Within MSE simulations, operating models (OMs) represent hypothesized dynamics relevant complexity system.Multiple OMs typically generated single reflect different uncertainties assess under uncertainty.Developing suitable requires analyst to, at minimum, define: life history characteristics fishing effort selectivity all affecting population; consider: spatial distribution any critical environmental covariates or species interactions.OMs should be calibrated (or "conditioned") on available data ensure projections consistent historical observations 2014).Due many considerations, developing sufficient time-intensive.Fortunately, requirements largely same as assessment.Due overlap in millions dollars invested assessments (Methot, 2015), approaches build previous products increase productivity (Maunder, 2014).Stock federally managed U.S. undergo substantial scrutiny during peer review process (Brown 2006;Lynch 2018), thus provide excellent starting point used MSE.

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 are: (1) engage stakeholders managers early often; (2) improve messaging communication about various uses models; (3) move forward with management under current authorities while exploring inclusive governance structures flexible decision-making frameworks for handling tradeoffs; (4) evaluate when modelling approach may be appropriate; (5) tailor model clearly defined purpose; (6) develop interdisciplinary solutions promoting applications; (7) make guidelines available review application; (8) ensure code well documented reproducible. draw from global assemblage subject matter experts who participated workshop entitled “Multispecies Modeling Applications Fisheries Management”.

Abstract Demands on freshwater for human use are increasing globally, but water resource development (WRD) has substantial downstream impacts fisheries and ecosystems. Our study evaluates trade-offs between WRDs ecosystem functioning considering alternative dam extraction options, diverse eco-hydrological responses catchment-to-coast connectivity. We used a data-driven ensemble modelling approach to quantify the of WRDs. WRD varied from weakly positive severely negative depending species, scenario cross-catchment synergies.

Invasive plant species (IPs) are widespread in forests and cause substantial environmental, economic social impacts. They occupy native ecological niches, causing local extinctions to the detriment of biodiversity disrupting ecosystem services provision. How landscape characteristics may determine success IPs remains unclear and, more importantly, how land-use land-cover changes result spatial shifts invasion risk. Furthermore, study factors influence biological invasions has focused on particular species, but not IPs’ community. In this study, we identify assess variables that presence distribution community temperate a global hotspot south-central Chile.

Abstract Anthropogenic alterations to river flow could have repercussions for flow-dependent species downstream but few studies account these dynamic relationships or quantify impacts of altered flow. Scylla serrata—a widely distributed portunid crab—was used as an example a model on abundance and catch. Crab population dynamics were modelled across large semi-enclosed tropical sea in northern Australia. Environmental drivers, primarily flow, also temperature the Southern Oscillation Index linked crab explain variability historical catches. Catch then be predicted under scenarios. River significantly improved ability catches some regions not all, strength this relationship varied catchments. Altered flows had negligible effects perennial rivers ephemeral temporally variable rivers, decreases catch ranged from 36 46% average. Our modelling approach showcases way dynamically rigorously key with potential help inform natural resource management, including policy decisions timing, quantity, method water removed rivers.
