Israeli Mediterranean Fisheries Economic Impact Analysis Using EwE Models

A research paper analyzes the Israeli Mediterranean fishery sector using the Ecopath with Ecosim (EwE) ecological models. The study quantifies the economic impact of climate change and nonindigenous species on the fishing value chain, including a financial multiplier effect. The work was authored by Eyal Ofir and last updated in May 2026.

Use Cases

• Modeling economic impacts of nonindigenous species biomass changes on a regional fishery based on the described scenario analysis.
• Analyzing employment distribution within a fish supply chain based on the finding that the restaurant sector accounts for 41% of jobs.
• Estimating the broader economic multiplier effect of fishing revenue based on the reported 1:3 fisher-to-supply-chain income ratio.
• Assessing the contribution of recreational versus commercial fishing to community well-being based on the described cultural and economic roles.

Strengths

• Includes a specific economic finding: a financial multiplier of four for the fishery sector.
• Quantifies a key employment statistic: the restaurant sector accounts for 41% of all employment in the supply chain.
• Applies a recognized analytical framework: the Ecopath with Ecosim (EwE) suite of ecological models.

Limitations

• The primary data file is a 281.8 KB PDF, suggesting the underlying model data or raw figures are not directly provided as a structured dataset.
• Column-level documentation is absent; field semantics must be inferred from the paper's text.
• Row count is unknown, which may limit suitability assessment for quantitative analysis.
