Benthic image surveys coupled with oxygen measurements in Saanich Inlet document a dense population in bottom conditions near anoxia (0.03\u2009ml\u2009l<jats:sup>\u22121<\/jats:sup> oxygen) where diel migrating zooplankton intersect the bottom; we confirm this species is a planktivore, which limits its depth range to the base of the migration layer. In a comparison with slender sole from a nearby well\u2010oxygenated habitat, several probable effects of living in severe hypoxia emerge: both sexes are significantly smaller in Saanich and the sex ratio is male\u2010skewed. Otoliths from the Saanich fish were difficult to read due to many checks, but both sexes were smaller at age with the largest female (20\u2009cm) from the hypoxia zone registering 17\u2009years. Hypoxia appears to have a direct consequence on growth despite good food supply in this productive basin. Hyperventilation, a low metabolic rate and a very low critical oxygen tension help this fish regulate oxygen uptake in severely hypoxic conditions; it will be particularly resilient as the incidence of hypoxia increases on the continental shelf. Data from small\u2010mesh bottom\u2010trawl surveys over four decades reveal an increase in mean annual catch per unit effort in southern regions of the province, including the outer shelf and the Strait of Georgia. The California Cooperative Oceanic Fisheries Investigations (CalCOFI) ichthyoplankton database records a general decline in fish larvae on the Oregon\u2013California shelf since 1990, but slender sole larvae are increasing there, as they are in the Strait of Georgia. We project that the slender sole will gain relative benefits in the future warming, deoxygenated northeast Pacific Ocean.<\/jats:p>","DOI":"10.1111\/jfb.14212","type":"journal-article","created":{"date-parts":[[2019,11,22]],"date-time":"2019-11-22T04:56:20Z","timestamp":1574398580000},"page":"394-407","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["An hypoxia\u2010tolerant flatfish: consequences of sustained stress on the slender sole <scp><i>Lyopsetta exilis<\/i><\/scp> (Pleuronectidae) in the context of a changing ocean"],"prefix":"10.1111","volume":"96","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2791-6337","authenticated-orcid":false,"given":"Verena","family":"Tunnicliffe","sequence":"first","affiliation":[{"name":"Department of Biology University of Victoria  Victoria British Columbia Canada"},{"name":"School of Earth &amp; Ocean Sciences University of Victoria  Victoria British Columbia Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryan","family":"Gasbarro","sequence":"additional","affiliation":[{"name":"School of Earth &amp; Ocean Sciences University of Victoria  Victoria British Columbia Canada"},{"name":"Department of Biology Temple University  Philadelphia Pennsylvania USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francis","family":"Juanes","sequence":"additional","affiliation":[{"name":"Department of Biology University of Victoria  Victoria British Columbia Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jessica","family":"Qualley","sequence":"additional","affiliation":[{"name":"Department of Biology University of Victoria  Victoria British Columbia Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicole","family":"Soderberg","sequence":"additional","affiliation":[{"name":"Department of Biology University of Victoria  Victoria British Columbia Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jackson W.
