Knowledge of Pacific Lamprey (Entosphenus tridentatus) in the Willamette River Basin.

Gabe SheoshipsWithin Our Reach 2012

IntroductionThe last century has not been kind to this species.

Pacific LampreyKsuyus’ (Sahaptin)Heesu’ (Nez Perce)Eel (Tribal people acquired this association from European settlers early 1900s).

Entosphenus tridentatus (Latin)

Origin story: Winner takes all

As the legend goes, the lamprey and sucker fish placed a wager over a swimming race. The lamprey lost, and thus lost all of it’s scales and bones to the sucker.

Seven Drum Washat’ Longhouse Religion

The creator designated the Ksuyus’ as a food source for the people, by the seven gill slits on it’s body.

Traditional usage of lamprey

Traditional Usage of Ksuyus’

First food honored each year in ceremony.

Biotherapy.Omega 3 oils beneficial for hair, skin tone, many other things.

Fertility promoting qualities.

Willamette Falls Fishery Management

Pre-Euro immigration, tribes valued Pacific Lamprey for 10,000 years~.

Traditional fishing location for: Nez PerceYakama tribes Warm Springs, Wasco, PauiteUmatilla, Cayuse, Walla WallaGrande Ronde, Kalapuyan, MollalaChinook, Clackamas, Tualatin

Willamette Falls TEKTribes practiced selective seasonal harvest management of Willamette Run.

Juvenile freshwater inhabitants outmigration related to lunar activity.

Adult fish were known to return to the Falls when precipitation declined.

Adult returns have always been “patchy” or highly variable.

Willamette Falls circa 1913

Willamette Falls

*Last abundant collection point for lamprey used in religious ceremonies by the tribes.

Past traditional harvest sites:

Celilo Falls (Inundation) Fifteenmile Creek (Poor returns)Kettle Falls/Columbia River (Inundation)Sherars Falls/Deschutes River (Poor returns) Savage Rapids Dam/Rogue River (Poor returns)Winchester Dam/Umpqua River (Poor returns)

IssueDeclining abundance of lamprey in Columbia

RiverAbundance of Pacific lamprey in the Willamette

Basin was first estimated in 2010Willamette Falls provides a opportunity for

capturing and tagging lamprey at fish ladders and inspecting lamprey at fish ladders and through lamprey harvest

But the area also presents a challenge…large area, high volume of water, and uncertainties of lamprey behavior through the falls/ladders

HarvestLack of

opportunity in Columbia River brings tribes from Idaho to coast

Typically occurs late June and July

Mark Recapture - AbundanceCapture lamprey in fish ladder April –

SeptemberMark with PIT tags and visible dart tagLamprey are released about 1 mile

downstreamInspecting lamprey for tags (“recaptured

fish”) occurs during taggingEstimate is made using the number marked

(tagged), recaptured and inspected for tags that had none

Project Objectives:

1. Determine timing and movement patterns during upstream migrations

2. Identify over-wintering locations

3. Determine relative use of primary tributaries for spawning

4. Formulate management recommendations

Tagging Summary

2008 (CTGR) 111 tagged lamprey were above the Falls.

Tracked by boat & by 11 fixed telemetry sites.

2009 (CTGR, CRAMER, PGE,OSU) 209 Tagged Lamprey were above the Falls Tracked by Boat, Plane and 22 fixed telemetry

sites.

2010 (CTGR, CRAMER,OSU) 219 tagged lamprey were above the Falls

Tracked by boat, plane and 22 fixed telemetry sites.

2011-2012 (CTGR) 120 tagged lamprey above the

Falls. Tracking by boat and 22 fixed sites.

Fixed Site Locations

Determine if lamprey spawn in the mainstem Willamette River.

Quantify the amount and quality of juvenile rearing habitat.

Monitor and quantify lamprey response to floodplain restoration work.

Identify and incorporate habitat needs for pacific lamprey into floodplain restoration design.

Lamprey Critical Uncertainties• Biology (basic; stress, disease; pop’n dynamics)

• Population structure (genetics)

• Habitat (use vs. avail; toxics; thresholds; climate change)

• Ecology (abundance, dist., prey, predators; keystone sp?)

• Monitoring (survey, collection, marking)

• Conservation (limiting factors; aquaculture)

• Management (passage, transloc., dredging, dewatering)

Tangible products needed….
