Abstract Stakeholders increasingly expect ecosystem assessments as part of advice on fisheries management. Quantitative models to support decision‐making may be either strategic (‘big picture’, direction‐setting and contextual) or tactical (focused management actions short timescales), with some informing the development models. We describe review ‘ M odels I ntermediate C omplexity for E cosystem assessments’ ( MICE ) that have a focus, including use assessment tools. are context‐...
Abstract In the domain of decision‐support tools for management marine fish resources, considerable attention has been paid to development models explaining how stocks change over space and time. most models, fishing effort is assumed be exogenous determined by factors such as management. Increasingly, there a call bio‐economic also account dynamics fleets, recognizing that fishers respond changing environmental, institutional economic conditions. A growing literature sought explicitly model...
Evaluating the success of natural resource management approaches requires methods to measure performance against biological, economic, social, and governance objectives. In fisheries, most research has focused on industrial sectors, with contributions global use by small-scale indigenous hunters fishers undervalued. Globally, fisheries sector alone employs some 38 million people who share common challenges in balancing livelihood lifestyle choices. We used as a case study fishery both...
Abstract Marine ecosystems evolve under many interconnected and area‐specific pressures. To fulfil society's intensifying diversifying needs while ensuring ecologically sustainable development, more effective marine spatial planning broader‐scope management of resources is necessary. Integrated ecological–economic fisheries models ( IEEFM s) systems are needed to evaluate impacts sustainability potential actions understand, anticipate ecological, economic social dynamics at a range scales...
Abstract To effectively implement an Ecosystem Approach to Fisheries (EAF), managers need consider the effects of management actions on fishery and ecosystem. Methods for assessing target stocks are generally well developed, but methods other components attributes ecosystem not. Area closures effort controls widely used tools that affect distribution fishing may therefore have consequences a range species habitats. An approach is developed predict area control biomass, production, richness...
Abstract Numerous studies have proposed methodologies to model fisher behaviour with the aim of predicting outcomes decision-making on board a fishing vessel. Both short- and long-term processes (e.g. investment) impact fleet dynamics. The structure models has tended depend upon nature fishery control variables (technical restrictions, quotas, effort control, and/or closed areas). For example, within context multi-stock, multi-fleet fisheries (mixed fisheries), skipper will allocate (as...
Abstract Tidd, A. N., Hutton, T., Kell, L. and Padda, G. 2011. Exit entry of fishing vessels: an evaluation factors affecting investment decisions in the North Sea English beam trawl fleet. – ICES Journal Marine Science, 68: 961–971. A profitable fishery attracts additional effort (vessels enter), eventually leading to overcapacity less profit. Similarly, vessels exit depending on their economic viability (or reduced expectations future benefits) or encouraged by schemes such as...
Abstract Punt, A. E., Deng, R. A., Dichmont, C. M., Kompas, T., Venables, W. N., Zhou, S., Pascoe, Hutton, Kenyon, R., van der Velde, and Kienzle, M. 2010. Integrating size-structured assessment bioeconomic management advice in Australia's northern prawn fishery. – ICES Journal of Marine Science, 67: 1785–1801. Three species fishery (Penaeus semisulcatus, P. esculentus, Metapenaeus endeavouri) are assessed using a population model that operates on weekly time-step. The parameters this...
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,...
Climate driven trends in ocean temperature and primary productivity are projected to differ greatly across the globe, likely triggering variable levels of concern for marine biota ecosystems. Quantifying these changes, complex ways which resource-dependent communities will need respond, is inherently difficult. Existing uncertainty about structure, function responses ecosystems, means that an ensemble model approach most robust considering potential ecosystem climate change. In this study,...
Abstract Changes in the distribution of seafood prices can provide useful insights into availability different species to fishermen and fish markets. We propose a log‐relative‐price‐index (LRPI) demonstrate how such concept might be for exploring long‐term changes wild communities as result intensive exploitation. estimate LRPI 26 Celtic Sea (UK) 33 on Italian In both systems changed significantly during recent decades, this probably resulted from decline high trophic level target cod hake...
The Torres Strait tropical rock lobster Panulirus ornatus (TRL) fishery is of immense social, cultural and economic importance to the region’s Indigenous fishers from both Australia Papua New Guinea (PNG). During 2020, COVID-19 pandemic indirectly impacted this as well a number other fisheries reliant on international export markets. TRL managed using an empirical (data-based) Harvest Control Rule (eHCR) rapidly provide recommended biological catch (RBC), based catch, fishery-independent...
Abstract Using length frequency distribution data (LFD) is cost-effective for estimating somatic growth in fish or invertebrates as are relatively easy to obtain. The recently developed R packages TropFishR and fishboot extend classic ELEFAN (Electronic LEngth Frequency ANalysis) programs include more powerful optimization procedures a bootstrap method uncertainties. Yet, the fundamental functions require users provide search conditions (e.g. upper lower limits each parameter, length-class...
