Current research and/or projects

Dr Robyn Forrest is a Research Scientist at the Pacific Biological Station, Nanaimo. She is a member of the Quantitative Assessment Methods Section, which collaboratively develops quantitative methods and tools to improve advice for sustainable management of Pacific fisheries.

Her work supports implementation of Canada's Sustainable Fisheries Framework and operationalization of an ecosystem approach to fisheries management (EAFM), especially for Pacific groundfish species.

Her main research interests are: management strategy evaluation (MSE) for fisheries; implementation of ecosystem-based fishery management; quantifying links between fish productivity, reference points and sustainable management for data-limited species; and performance of fishery management systems. 

Current projects include:

  • Development and simulation-testing a framework to select management procedures for data-limited groundfish species.
  • Using simulation to identify robust approaches for accounting for environmental change in strategic and tactical management of fisheries.
  • Analysis of spatial changes in fishing effort in BC's groundfish fishery following major management changes.

Since 2016, she has fostered a major partnership between DFO and the developers of the Data-Limited Toolkit (DLMtoolCarruthers and Hordyk 2018), a powerful MSE software package to support decision-making for Canadian fish stocks along the continuum of data-availability. DLMtool has so far been used to support development of a Management Procedure Framework for BC groundfish stocks (Anderson et al. in press); the rebuilding plan for Inside Yelloweye Rockfish (Haggarty et al. in press); and management advice for Bay of Fundy Herring.

She is a member of DFO's National Sustainable Fisheries Working Group, which is tasked with interpretation and operationalization of the new Fish Stocks provisions of Canada's Fisheries Act.

Recent stock assessments for BC groundfish include Pacific Cod (Gadus macrocephalus), Arrowtooth Flounder (Atheresthes stomas), and the inside stock of Yelloweye Rockfish (Sebastes ruberrimus).

International experience and/or work

  • Dr Forrest represents Canada as a member of the Advisory Committee of the International Council for the Exploration of the Sea (ICES).
  • She was Canadian Advisor to the Commissioners of the International Pacific Halibut Commission (IPHC) from 2011 to 2016.
  • She recently collaborated with scientists at the IPHC on a study evaluating avoidance of rockfish habitat by the BC Halibut fleet following major reductions in Yelloweye Rockfish quota (Forrest et al. 2020).
  • In 2011 and 2012, she collaborated with NOAA scientists on stock assessments for Pacific Hake (Merluccius productus).
  • In 2006, she collaborated with scientists at Australia's Commonwealth Scientific and Industrial Research Organization (CSIRO), evaluating impacts of trawl fisheries and comparing strategic advice arising from structurally-distinct ecosystem models (Forrest et al. 2015 and Savina et al. 2013).
