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.

Fish assemblages in eelgrass beds of Bellingham Bay, Washington, Northern Puget Sound, 2019
Puget Sound is a critical part of the Pacific Northwest, both culturally and economically. Eelgrass beds are an important feature of Puget Sound and are known to influence fish assemblages. As part of a larger site-characterization effort, and to gain a better understanding of the fish assemblages in Bellingham Bay, Washington, four eelgrass beds (Zostera marina) along the shoreline were surveyed.

Maternal transfer of polychlorinated biphenyls in Pacific sand lance (Ammodytes personatus), Puget Sound, Washington
We measured polychlorinated biphenyls (PCBs) in multiple age and size classes of Pacific sand lance (Ammodytes personatus), including eggs, young-of-the year, and adults to evaluate maternal transfer as a pathway for contaminant uptake and to add to the limited information on the occurrence of PCBs in sand lance in Puget Sound. Sampling was replicated at an urban embayment (Eagle Harbor) and a sta

Effects of dewatering on behavior, distribution, and abundance of larval lampreys
Anthropogenic dewatering of aquatic habitats can cause stranding and mortality of burrowed larval lampreys; however, the effects of dewatering have not been quantified. We assessed: (a) changes in spatial distribution, abundance, and emergence of larvae dewatered at Leaburg Reservoir (OR); (b) emergence and mortality of larvae dewatered in a laboratory; and (c) bias, precision, and interpretation

A standard operating procedure for the preparation of purposely killed juvenile salmon used to test survival model assumptions
This document describes a standard operating procedure (SOP) for the preparation of purposely killed juvenile salmon, implanted with telemetry transmitters, to be released into rivers, lakes, or streams to test one of the survival model assumptions. Procedures for releases of purposely killed fish (hereinafter dead fish releases) were developed by staff from the U.S. Geological Survey’s Columbia R

Legacy and current-use toxic contaminants in Pacific sand lance (Ammodytes personatus) from Puget Sound, Washington
Forage fish are primary prey for seabirds, fish and marine mammals. Elevated levels of pollutants in Puget Sound, Washington salmon and killer whale tissues potentially could be sufficiently high to elicit adverse effects and hamper population recovery efforts. Contaminant transfer and biomagnification of the toxic compounds measured in this study likely contribute to those elevated concentrations

Evidence for rapid gut clearance of microplastic polyester fibers fed to Chinook Salmon: A tank study
Marine and freshwater plastic pollution is a challenging issue receiving large amounts of research and media attention. Yet, few studies have documented the impact of microplastic ingestion to aquatic organisms. In the Pacific Northwest, Chinook salmon are a culturally and commercially significant fish species. The presence of marine and freshwater microplastic pollution is well documented in Chin

Behavior and movement of adult winter steelhead (Oncorhynchus mykiss) in the upper Cowlitz River Basin, Washington, 2017–18
Executive SummaryA 2-year radiotelemetry study was completed to monitor the movements of adult winter steelhead (Oncorhynchus mykiss) in the upper Cowlitz River Basin. A reintroduction program was established to restore healthy and harvestable populations of steelhead because volitional access to the area was blocked in the 1960s after construction of dams in the lower river.

Evaluating dewatering approaches to protect larval Pacific lamprey
Executive SummaryLarval Pacific lamprey live for several years burrowed in nearshore sediments where they filter feed on detritus and organic matter. Dewatering of larval habitat can occur as a result of flow-management practices, construction projects, or seasonal closures of irrigation diversions. Effective management of dewatering events requires guidance on approaches to protect lamprey, such

Distribution of adult Chinook salmon (Oncorhynchus tshawytscha) in relation to water temperatures, Lake Scanewa, Cowlitz River, Washington, 2012
A trap-and-haul program is operated to move anadromous Pacific salmon (Oncorhynchus spp.) around dams and reservoirs in the Cowlitz River basin, Washington. The primary release site for adult fish is in Lake Scanewa, a small reservoir created by Cowlitz Falls Dam, the uppermost dam in the basin. Releases in the reservoir are terminated when reservoir water temperature is 16 degrees Celsius (°C) or

Movements of juvenile Pacific Lamprey (Entosphenus tridentatus) in the Yakima and Columbia Rivers, Washington, 2018—A pilot study using acoustic telemetry
Telemetry has been an invaluable tool to improve our understanding of adult Pacific Lamprey (Entosphenus tridentatus) movements and to guide management approaches to protect and restore this species of concern. Juvenile and larval lamprey, however, are much smaller than adults, and have not been monitored with telemetry because available transmitters have traditionally been too large. With funding
