Twenty-six years ago, in response to regionally devastating fisheries collapses in Canada, Hutchings et al. asked "Is scientific inquiry incompatible with government information control?" Now, a quarter-century later, we review how government science advice continues to be influenced by non-science interests, particularly those with a financial stake in the outcome of the advice. We use the example of salmon aquaculture in British Columbia, Canada, to demonstrate how science advice from Fisheries and Oceans Canada (DFO) can fail to be impartial, evidence-based, transparent, and independently reviewed—four widely implemented standards of robust science advice. Consequently, DFO's policies are not always supported by the best available science. These observations are particularly important in the context of DFO having struggled to sustainably manage Canada's marine resources, creating socio-economic uncertainty and putting the country's international reputation at risk as it lags behind its peers. We conclude by reiterating Hutchings et al.'s unheeded recommendation for a truly independent fisheries-science advisory body in Canada to be enshrined in the decision-making process.

Environmental DNA (eDNA) monitoring methods have played a significant role in improving fisheries management decisions. Yet, their impact to date has been rather limited in Canada, where eDNA sampling and analyses are only beginning to be used to inform management and conservation decisions, practices, and policies. Studies investigating hurdles to the incorporation of eDNA evidence into fisheries management decisions generally focus on technical challenges (i.e., risks of false-positive and false-negative detections). We set out to identify challenges that eDNA researchers and conservation practitioners must overcome to fully unlock the benefits of eDNA sampling for fish management in the Canadian context. We discuss aspects of the broad and heterogeneous geography, preponderance of regions located far from densely populated areas, complex political landscape, and cultural diversity of Canada that may complicate the design of reliable eDNA monitoring tools or restrict their use if not adequately addressed. To advocate for the wider use of eDNA sampling, we outline a number of action items that would facilitate the broad adoption of eDNA sampling as a monitoring tool at the Canadian scale.

Fisheries are complex social–ecological systems, meaning that the achievement of 'sustainable' fisheries demands a multifaceted approach, involving ecological, economic, social, and institutional dimensions. Addressing these diverse concerns requires the collection and synthesis of new sources of information by science-advising bodies and the engagement of multiple knowledge types from rightsholders and stakeholders. The 'modernized' (2019) Fisheries Act in Canada allows for a diverse range of considerations to form the basis of fisheries management decisions, including knowledge from community or industry groups, but it remains unclear where and when such information is available, how this information is prioritized, who contributes to information-gathering processes, and what the management consequences of information use might be. The present study uses a selection of science-advising documents and briefing notes for decision makers to explore the information and priorities informing fisheries management decisions in Atlantic Canada, with a focus on how rightsholders and stakeholders contribute to the process. These findings can inform efforts to adopt an inclusive and participatory approach to evidence-based decision making to achieve sustainable fisheries, in the broadest sense of the word.
