  • Is a research unit within the UBC Institute for the Oceans and Fisheries
  • Collaborates with other UBC research units and governmental, NGO and industrial organizations
  • Develops innovative data analysis and simulation evaluation tools to help solve fisheries management problems in Canada and other countries

The Research Program


Develops new analytical software tools to:

  • Characterize the dynamics of exploited fish populations and fishing fleets
  • Improve understanding of the seasonal movements and habitat use of migratory fishes and crustaceans
  • Improve understanding of how changes in predator populations can alter population dynamics of key fish populations
  • Evaluate the status of exploited fish populations
  • Evaluate the potential short and long-term consequences of different fisheries management options accounting for the above

  • To fill gaps in the data e.g. on seasonal fish movements and habitat use and predator diets
  • To improve the empirical basis for fish stock assessments

Some research questions under investigation:

  • Which management control methods work best in data limited commercial fisheries?
  • What’s been the role of predator-prey interactions in the collapse of the trophy rainbow trout fishery in Kootenay Lake and which management options are most likely bring about recovery?
  • How has angling effort in B.C. lakes responded over the last two decades to different stocking regimes and angling regulations?
  • Do diet and predation rate data support the predator pit hypothesis for Salish Sea Chinook and Coho stocks and what are the long-term consequences for these stocks of different fisheries management controls?
  • What have been the roles of predation by Atlantic gray seals and small pelagic fishes in the continued decline in the collapsed stock of Gulf of St. Lawrence Atlantic cod?
  • Which monitoring regimes and management strategies work best when the fish recruitment processes undergo long-term systematic variations?
