Following exhaustion at Ucrit,recovery time was 42\u201378 min, depending upon the fish stock. The recovery times are several-fold shorter than previously reported for juvenile,hatchery-raised salmonids. EPOC varied fivefold among the fish stocks, being greatest for Gates Creek sockeye salmon (O. nerka), which was the salmon stock that had the longest in-river migration, experienced the warmest temperature and achieved the highest maximum oxygen consumption compared with the other salmon stocks that were studied. EPOC was related to Ucrit, which in turn was directly influenced by ambient test temperature. The non-aerobic cost of swimming to Ucrit was estimated to add an additional 21.4\u201350.5%to the oxygen consumption measured at Ucrit. While these non-aerobic contributions to swimming did not affect the minimum cost of transport, they were up to three times higher than the value used previously for an energetic model of salmon migration in the Fraser River, BC, Canada. As such, the underestimate of non-aerobic swimming costs may require a reevaluation of the importance of how in-river barriers like rapids and bypass facilities at dams, and year-to-year changes in river flows and temperatures,affect energy use and hence migration success.<\/jats:p>","DOI":"10.1242\/jeb.00548","type":"journal-article","created":{"date-parts":[[2003,8,8]],"date-time":"2003-08-08T17:56:09Z","timestamp":1060365369000},"page":"3253-3260","source":"Crossref","is-referenced-by-count":232,"title":["Excess post-exercise oxygen consumption in adult sockeye(<i>Oncorhynchus nerka<\/i>) and coho (<i>O. kisutch<\/i>) salmon following critical speed swimming"],"prefix":"10.1242","volume":"206","author":[{"given":"C.
