Refining Fisheries Advice With Stock-Specific Ecosystem Information
نویسندگان
چکیده
Although frequently suggested as a goal for ecosystem-based fisheries management, incorporating ecosystem information into stock assessments has proven challenging. The uncertainty of input data, coupled with the structural complex multi-species models, currently makes use absolute values from such models contentious short-term single-species management advice. Here, we propose different approach where standard assessment methodologies can be enhanced using model derived information. Using case study Irish Sea, illustrate how stock-specific indicators used to set an fishing mortality reference point (F ECO ) within “Pretty Good Yield” ranges which form present precautionary adopted in Europe by International Council Exploration Sea (ICES). We that this new target, F , scale down when conditions are poor and up good. This provides streamlined quantitative way catch advice opportunity operationalize empirical indicators, while retaining integrity current MSY -based process.

International Fisheries Agreements with a Shifting Stock
When a fish stock shifts from one nation to another nation, e.g. due to climate change, the nation that loses the resource has incentives to deplete it while the other nation, receiving the resource, has incentives to conserve it. We propose an analytical model to study under which circumstances self-enforcing agreements can align incentives. Our setup allows to distinguish between a fast and a...
متن کاملStock assessment and end-to-end ecosystem models alter dynamics of fisheries data
Although all models are simplified approximations of reality, they remain useful tools for understanding, predicting, and managing populations and ecosystems. However, a model's utility is contingent on its suitability for a given task. Here, we examine two model types: single-species fishery stock assessment and multispecies marine ecosystem models. Both are efforts to predict trajectories of ...
متن کاملRefining Influence Diagram For Stock Portfolio Selection
In this paper, we propose use of the influence diagram for stock portfolio selection. We use an algorithm that applies the mutual information as the metric to guide the refinement of the influence diagram. We applied the algorithm to the conceptual refinement of the influence diagram. We tested our algorithm to a specific domain – portfolio selection; the result is impressive compared to the S&...
متن کاملBreathing life into fisheries stock assessments with citizen science
Citizen science offers a potentially cost-effective way for researchers to obtain large data sets over large spatial scales. However, it is not used widely to support biological data collection for fisheries stock assessments. Overfishing of demersal fishes along 1,000 km of the west Australian coast led to restrictive management to recover stocks. This diminished opportunities for scientists t...
متن کاملExpectation-Stock Dynamics in Multi-Agent Fisheries
In this paper we consider a game-theoretic dynamic model describing the exploitation of a renewable resource. Our model is based on a Cournot oligopoly game where n profit-maximizing players harvest fish and sell their catch on m markets. We assume that the players do not know the law governing the reproduction of the resource. Instead they use an adaptive updating scheme to forecast the future...
