Theresa "Marty" Liedtke
Marty Liedtke is a Project Leader at the Columbia River Research Laboratory with 25+ years of experience focused on movement, behavior, and performance of fishes in both freshwater and marine systems.
My research is currently focused on Pacific Lamprey and other native lampreys in the Columbia River Basin and forage fishes in Puget Sound. My team evaluates juvenile and larval lamprey performance under controlled laboratory conditions to address management needs such as dewatering of lamprey habitat, interactions with screens at water diversions, and dredging impacts. A newly developed, prototype acoustic telemetry transmitter, designed for use in lamprey and eels allowed us to conduct one of the first acoustic telemetry studies of juvenile Pacific lamprey migration movements. Prior to the development of this transmitter such studies were not possible due to the small size of these fish. In Puget Sound we have focused on Pacific sand lance and surf smelt and have evaluated spawning site selection, responses to climate change, food habits, and rearing habitats. Most recently we are investigating linkages between forage fishes and legacy and current use contaminants in both field and laboratory settings.
Historically my team has conducted radio and acoustic telemetry studies to evaluate juvenile salmon passage and survival at hydroelectric dams in the Columbia River Basin. We have used telemetry to monitor the behavior and movements of many fishes, including adult salmonids using transmitters with sensors (temperature, motion). I have developed standard operating procedures for surgical implantation of transmitters and regularly train others to design tagging operations and conduct tagging for telemetry studies. I am interested in the performance of fish equipped with telemetry transmitters, specifically comparing the stress response, swimming performance, buoyancy compensation, and predator avoidance ability of tagged fish to untagged fish.

Emigration and transportation stress of juvenile Chinook salmon relative to their reintroduction upriver of Shasta Dam, California, 2017–18
The Bureau of Reclamation supports the Shasta Dam Fish Passage Evaluation (SDFPE; Yip, 2015) program, and in 2016 set out to determine the feasibility of reintroducing winter-run and spring-run Chinook salmon (Oncorhynchus tshawytscha) and steelhead (O. mykiss) to tributaries upstream of Shasta Dam. Ideally, reintroduction strategy includes trapping naturally produced downstream-migrating juvenileAuthorsNoah S. Adams, Theresa L. Liedtke, John M. Plumb, Lisa K. Weiland, Amy C. Hansen, Scott D. EvansResponses of hatchery‐ and natural‐origin adult spring Chinook Salmon to a trap‐and‐haul reintroduction program
The construction of impassable dams severely affected many Pacific salmon Oncorhynchus spp. populations, resulting in reintroduction efforts that are now focused on returning anadromous fish to areas located upstream of these dams. A primary strategy for moving adult salmon and steelhead O. mykiss around a dam or multiple dams involves trapping fish downstream and transporting them to upstream areAuthorsTobias J.

A multi-year evaluation was conducted during 2010–16 to evaluate passage survival of juvenile steelhead (Oncorhynchus mykiss), Chinook salmon (O. tshawytscha), and coho salmon (O. kisutch) in Lake Scanewa, and at Cowlitz Falls Dam in the upper Cowlitz River Basin, Washington. Reservoir passage survival was evaluated in 2010, 2011, and 2016, and included the tagging and release of 1,127 juvenile saAuthorsTheresa L. Liedtke, Tobias J. Kock, William HurstEffectiveness of common fish screen materials for protecting lamprey ammocoetes—Influence of sweeping velocities and decreasing flows
In previous tests of the effectiveness of four common fish screen materials for excluding lamprey ammocoetes, we determined that woven wire (WW) allowed substantially more entrainment than perforated plate (PP), profile bar (PB), or Intralox (IL) material. These tests were simplistic because they used small vertically-oriented screens positioned perpendicular to the flow without a bypass or a sweeAuthorsMatthew G. Mesa, Theresa L. Liedtke, Lisa K.

The Yolo Bypass is a flood control bypass in Sacramento Valley, California. Flood plain habitats may be used for juvenile salmon rearing, however, the potential value of such habitats can be difficult to evaluate because of the intermittent nature of inundation events. The Yolo Bypass Juvenile Salmon Utilization Study (YBUS) used acoustic telemetry to evaluate the movements and survival of juvenilAuthorsTheresa L. Liedtke, William R.

Recent interest in flood control and restoration strategies in the Chehalis River Basin has increased the need to understand the current status and ecology of spring Chinook salmon (Oncorhynchus tshawytscha). Spring Chinook salmon have the longest exposure of all adult Chinook salmon life histories to the low-flow and high water temperature conditions that typically occur during summer.

Recent interest in flood control and restoration strategies in the Chehalis River Basin has increased the need to understand the current status and ecology of spring Chinook salmon.

A multiyear radiotelemetry evaluation was conducted to monitor adult steelhead (Oncorhynchus mykiss), Chinook salmon (O. tshawytscha), and coho salmon (O. kisutch) behavior and movement patterns in the upper Cowlitz River Basin. Volitional passage to this area was eliminated by dam construction in the mid-1960s, and a reintroduction program began in the mid-1990s. Fish are transported around the dAuthorsTobias J.

Survival of out-migrating juvenile Chinook salmon (Oncorhynchus tshawytscha) in the Sacramento–San Joaquin River delta, California, USA, varies by migration route. Survival of salmonids that enter the interior and southern Delta can be as low as half that of salmonids that remain in the main-stem Sacramento River.

Hatchery ‘recycling’ programs have been used to increase angling opportunities by re-releasing fish into a river after they returned to a hatchery or fish trap. Recycling is intended to increase opportunities for fishermen, but this strategy could affect wild fish populations if some recycled fish remain in the river and interact with wild fish populations. To quantify hatchery return and angler hAuthorsTobias J. Kock, Russell W. Perry, Chris Gleizes, Wolf Dammers, Theresa L.

Collection of juvenile salmon at Cowlitz Falls Dam is a critical part of the effort to restore salmon in the upper Cowlitz River, Washington. Many of the fish that are not collected pass downstream and enter Riffe Lake, become landlocked, and are lost to the anadromous population. In addition to this loss, the juvenile fish collection system at Cowlitz Falls Dam, which originally consisted of fourAuthorsTobias J. Kock, Theresa L. Liedtke, Brian K.
