Salmonid Swimming Performance in Relation to Passage Wightman, J.C.
1976

Abstract: In order to establish standards for culvert design and installation to ensure fish passage, a review of existing literature on fish swimming performance in culverts and in conditions resembling those in culverts was undertaken. Measured swimming abilities of game (mainly salmonids) and non-game fish species were taken from many sources. Swimming capabilities at different life-history stages under various physical and chemical conditions were documented. Under proper stimulus (undefined) adult salmon and steelhead (length 63.5-76.2 cm) have travelled distances up to 30.5 m against water velocities near 820 cm/sec. Normally, adult salmon and large trout are capable of negotiating velocities of 370 cm/sec over shorter distance (6.1 m). To ensure fish passage through a culvert, water velocities should be much less than the sustained swimming speed of upstreaming fish for a reasonable length of time. For salmonid under-yearlings, this would definitely be <30 m/sec and nearer 15 cm/sec. Some other important factors
