However, salmon numbers are dwindling and many questions remain as to the causes. Growing evidence points to juvenile survival in the marine environment as particularly critical, yet little is known about the pressures the young fish endure through this period. Hakai researchers are maximizing their vantage point from the Quadra Island Ecological Observatory, which lies at the intersection between the rearing grounds in the Strait of Georgia and the narrow passages of the Discovery Islands and Johnstone Strait that the salmon need to navigate on their journey north. <\/span><\/p>\n<h3>Key Questions<\/h3>\n<ul>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Timing of peak migration for juvenile salmon is highly variable, but so too has been the variability of oceanic conditions since monitoring began in 2015 <\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Poor feeding conditions in the Discovery Islands and Johnstone Strait make these areas a bottleneck for growth during their northward migration<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">The migration path that they choose through the Discovery Islands has bearing on their survival success, though the sources of mortality remain unknown<\/span><b> \u00a0<\/b><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Weak oceanographic connections between waters north and south of the Discovery Islands lead to regionally distinct salmon prey<\/span><\/li>\n<\/ul>\n<h3>Our Focus<\/h3>\n<div class=\"mceTemp\"><\/div>\n<p><span style=\"font-weight: 400;\">Hakai is bringing together an interdisciplinary research program in partnership with researchers at the University of British Columbia, University of Toronto, Simon Fraser University, the Pacific Salmon Foundation, and Fisheries and Oceans Canada. To understand how the ocean impacts the salmon population as they migrate north, we combine salmon sampling with high frequency oceanographic observations and track the dynamics of the ocean food web using traditional microscopy and the latest genomic technology.<\/span><\/p>\n<figure id=\"attachment_3749\" aria-describedby=\"caption-attachment-3749\" style=\"width: 575px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-3749 size-medium\" src=\"https:\/\/hakai.org\/wp-content\/uploads\/Screen-Shot-2019-03-22-at-1.10.58-PM-web-575x575.jpg\" alt=\"\" width=\"575\" height=\"575\" srcset=\"https:\/\/hakai.org\/wp-content\/uploads\/Screen-Shot-2019-03-22-at-1.10.58-PM-web-575x575.jpg 575w, https:\/\/hakai.org\/wp-content\/uploads\/Screen-Shot-2019-03-22-at-1.10.58-PM-web-272x272.jpg 272w, https:\/\/hakai.org\/wp-content\/uploads\/Screen-Shot-2019-03-22-at-1.10.58-PM-web-768x768.jpg 768w, https:\/\/hakai.org\/wp-content\/uploads\/Screen-Shot-2019-03-22-at-1.10.58-PM-web-1180x1180.jpg 1180w, https:\/\/hakai.org\/wp-content\/uploads\/Screen-Shot-2019-03-22-at-1.10.58-PM-web-2000x2000.jpg 2000w\" sizes=\"(max-width: 575px) 100vw, 575px\" \/><figcaption id=\"caption-attachment-3749\" class=\"wp-caption-text\">Hakai staff document juvenile salmon as they transit through the Discovery Islands.

Up to 90 percent of the juvenile sockeye that head to sea from the Fraser River are thought to travel northward through the Strait of Georgia, Discovery Islands, and Johnstone Strait. This research aims to fill critical gaps in our knowledge of juvenile salmon early marine life that will ultimately contribute to protecting the Fraser River salmon sockeye, and other species, for future generations.<\/span><\/p>\n<div class=\"special-series-text\">\n<h3>Reports<\/h3>\n<div class=\"mceTemp\"><\/div>\n<p><a href=\"https:\/\/hakai.org\/wp-content\/uploads\/Juvenile-Salmon-Report-Apr-Sep-2018.pdf\">Apr &#8211; Sep 2018<\/a><\/p>\n<\/div>\n<section class=\"pubsection\">\n<h3>Select Papers<\/h3>\n<p>Hunt, B.P.V., B.T.
