FISHERIES ECOLOGY

Research Interests

  • Regional fisheries research programmes in the Western Indian Ocean
  • Fisheries ecology
  • Spiny lobster biology
  • Gear impacts on the marine environment
  • Stock assessments
  • Bycatch of long-line fisheries
  • Functioning of large marine ecosystems
