Patrick Ouellet

Research Scientist, Environmental and Ocean Sciences Branch, Regional Science Branch

Current research and/or projects

My research activities centre on the larval stages of fish and decapod crustaceans, and on investigation of the processes responsible for the annual variations in recruitment of commercial species. The matter of annual variability of recruitment is approached from several angles, and a number of disciplines (biology, ecology, physiology and oceanography) play a part in my research. Also, my research involves both laboratory experiments and major at-sea missions. I am also interested in the issue of the maternal effect on larval quality and the impact of larval quality on population productivity or recruitment.

Research and/or project statements

  • Influence of oceanic conditions on the survival of larval stages and the recruitment of exploited fish and decapod crustacean species.
  • Influence of the parental effect (quality of the reproductive adults) on the phenotype and survival chances of the larval stages.
  • Ecology and biology of larval stages using an approach that combines laboratory experiments and field work.
  • Fisheries oceanography.
