In recent posts we covered the basics of defining escapement and run size, and the ways these are measured by resource managers. Today, we turn our focus to the complex terminology used for describing and comparing hatchery and wild steelhead. Steelhead are typically referred to as either being “wild” or “hatchery,” but they may also be defined as being “native” …
Steelhead 101: Using snorkel surveys to estimate adult steelhead escapement
Another week, another post on how scientists and fisheries managers measure steelhead escapement. Last week, we described redd counts and why they are an important tool. This week, we review snorkel surveys. Snorkel surveys entail divers swimming in the river and visually counting adult steelhead. Like redd counts, snorkel surveys do not cover an entire river, but rather break …
We Are Wild Steelheaders
Wild Steelheaders United is announcing our “We are Wild Steelheaders Month,” a celebration of wild steelhead across their native range in the Western U.S. For the next month we will be posting videos of anglers up and down the West Coast, discussing why wild steelhead matter to them. Anglers of all persuasions support better management of wild steelhead stocks. But to reach …
Sportfishing Industry asks Trump for solid review of Snake River Dams
More than 50 fishing companies, trade groups and conservation organizations sent a letter today to President Donald Trump in support of taking a fresh look at removing four large dams on the lower Snake River to recover wild salmon and steelhead that once thrived in the Snake River Basin of Idaho, Oregon and Washington. With a court-ordered comprehensive analysis …
How many steelhead can you fit into a school?
It depends on how old and big they are. Over the past year we have talked extensively about the value of life history diversity in steelhead, and in particular, that a broader range in spawn timing – which results in a broader range of emergence for juveniles – can help ameliorate density-related impacts by spreading steelhead of various ages …
Steelhead biology for anglers
One thing you will notice about anglers who have spent a lot of time on the water, and I mean a potentially unhealthy amount of time on the water, is they catch fish. This can be frustrating to new anglers who are just learning to steelhead fish and spend many fishless days casting. There is no substitute for time …
Life history diversity: dispersing risk
By Brian Hodge Just as investors diversify their portfolio of assets to minimize financial loss, fisheries managers may diversify their portfolio of conservation strategies to minimize species loss. Another fishy analog for the “portfolio effect” comes from the steelhead—it reduces risk of extinction by displaying a diverse array of life histories, or pathways from hatch to spawn. My colleagues and …
Rivers of Resilience – Asotin Creek
Asotin Creek is a tributary that drains into the Snake River near the town of Asotin in eastern Washington. With a drainage area of 250 square miles, Asotin Creek is slightly larger than the Wind River, but also much smaller than the Yakima River watershed. Like the Yakima, the basin is located in a semi-arid environment. Most of the watershed …
Rules for catch-and-release of steelhead
There is no worse feeling than bringing a steelhead to hand and seeing the gills pumping blood. Such experiences are one of the reasons that anglers have created flies that reduce deep hookings. Still, fishing is a blood sport, and despite our best efforts, we ultimately cannot eliminate the potential for some mortality. While we can’t control where the …
A Better Way
Tim Frahm, Central Coast Steelhead Coordinator for Trout Unlimited, admires the newly restored Carmel River above the site of the old San Clemente Dam at the celebration event on June 6. By Sam Davidson There have no doubt been many parties on the Carmel River, one of the best steelhead streams on California’s south-central coast, over the years. This scenic …
