Area of Expertise:

Dr. Antonio Velez-Espino is a quantitative biologist with broad experience on demographic modelling, population viability analysis, fisheries models, mark-recapture analytical methods, multivariate statistics, time series analyses, decision analysis, computer simulations, and multiple applications of statistical techniques for diverse research objectives (e.g., forecast methodologies, stock-recruit analysis, invasion dynamics studies, sea lamprey control, salmon stock assessment, population dynamics as part of recovery potential assessments for freshwater species at risk, scientific advice for Pacific salmon management under the umbrella of the Pacific Salmon Commission, etc.).

Dr. Velez-Espino has experience conducting independent research on fish population science, fish stock assessment, fisheries productivity, fish habitat science, aquatic invasive species, and aquaculture science. His main contributions to science within the Government of Canada include:

  • Developing quantitative approaches to estimate allowable harm and recovery targets for aquatic species at risk.
  • Modeling the probabilities of establishment and invasion dynamics of aquatic invasive species.
  • Developing methodologies to estimate minimum viable population size and quantify critical habitat in freshwater fishes.
  • Conducting stock assessment of Chinook salmon stocks.
  • Providing scientific advice through the Chinook Technical Committee of the Pacific Salmon Commission to improve management and recovery of salmon stocks.
