Fields of activity

  • Bycatch reduction in active and passive fisheries
  • Development and testing of fishing gear technologies to address species and size selectivity in mixed fisheries
  • Sampling scheme planning and cruise leadership in experimental sea trials
  • Quantitative and qualitative assessment of species/size selection and relative catchability of fishing gears

Research interests

Fishing gears, trawl hydrodynamics and efficiency, trawl size selection, species selection in mixed fisheries, bycatch, fishing discards, fish behaviour, sampling design, programming, computer simulation, statistics (parametric and non-parametric regression tools, Mixed modelling, non-parametric inference tools [bootstrapping, jackknife, cross-validation and others], multivariate analysis)
