Evaluating injury and mortality to larval lamprey collected out of sediment using a portable suction dredge Evaluating injury and mortality to larval lamprey collected out of sediment using a portable suction dredge
Dataset describes the findings of a combination of field and laboratory tests to see if larval lamprey were injured or killed after they were collected from their burrows in sediment using a portable suction dredge.
Counts, Fish Weights, and Spectral Data from a Juvenile Chinook Salmon Polyester Microplastic Fiber Exposure Study Counts, Fish Weights, and Spectral Data from a Juvenile Chinook Salmon Polyester Microplastic Fiber Exposure Study
This release includes all data collected in support of a juvenile Chinook salmon exposure study designed to understand the retention of microplastic clothing fibers (hereon referred to as "microfibers") after feeding. To understand the potential impacts of microfiber ingestion to fish, we ran a feeding experiment with juvenile Chinook salmon to determine if ingested fibers are retained...

Performance comparisons for artificially propagated and wild Pacific lamprey juveniles and larvae Performance comparisons for artificially propagated and wild Pacific lamprey juveniles and larvae
Artificially propagated Pacific lamprey (Entosphenus tridentatus) are produced for restoration and for use in dam passage studies to reduce the demand for wild fish. Such uses require that animals are representative of their wild counterparts. Previous work indicated that this is true for Pacific lamprey larvae and juveniles reared in the hatchery with respect to the length of sustained...

Defining sediment handling practices to limit negative impacts to larval lampreys Defining sediment handling practices to limit negative impacts to larval lampreys
Sediment manipulation activities such as dredging and restoration efforts (e.g., culvert install/repair) may disturb habitats where larval lampreys live burrowed in stream sediments. Sediment added on top of larval lamprey burrowing areas results in ‘overburden’, which poses risks of mortality from respiratory distress, reduced movement, and crushing injuries or may have sublethal...

Pacific Lamprey responses to stressors: Dewatering and electrofishing Pacific Lamprey responses to stressors: Dewatering and electrofishing
The Pacific Lamprey Conservation Initiative (PLCI) is a collaboration of Tribes, Federal, and State agencies working together to protect and restore Pacific Lamprey (Entosphenus tridentatus) and other native lampreys (i.e., Lampetra spp.) in Alaska, Washington, Oregon, California, and Idaho. The U.S. Fish and Wildlife Service hosts and facilitates the PLCI, and the Columbia River Tribes...

First investigations on lamprey responses to elevated total dissolved gas exposure and risk of gas bubble trauma First investigations on lamprey responses to elevated total dissolved gas exposure and risk of gas bubble trauma
A flexible spill program in the federal Columbia River power system increased the total dissolved gas (TDG) water quality standards (i.e., the gas cap) from 120% to 125%. Spill is used to pass juvenile salmon (Oncorhynchus spp.) over dams, but it can generate elevated TDG, and exposed fish can develop gas bubble trauma (GBT) or experience mortality. Juvenile salmon are monitored for GBT...

Influence of lamprey rearing type on measures of performance Influence of lamprey rearing type on measures of performance
Declines in populations of Pacific Lamprey (Entosphenus tridentatus) have raised concerns by the Columbia River tribes, who then initiated efforts to protect and restore them throughout their historical range. The Columbia River Inter-Tribal Fish Commission (CRITFC) devised a restoration plan for lamprey in the Columbia River Basin which highlights the significance of lamprey to the...

Salvage using electrofishing methods caused minimal mortality of burrowed and emerged larval lampreys in dewatered habitats Salvage using electrofishing methods caused minimal mortality of burrowed and emerged larval lampreys in dewatered habitats
Objective Human-induced dewatering of freshwater habitats causes mortality of larval lampreys (family Petromyzontidae). Salvage by electrofishing at dewatering events is assumed to reduce this mortality, but to our knowledge this assumption remains unassessed.Methods We estimated mortality of salvaged larval lampreys (Lampetra spp. and Pacific Lamprey Entosphenus tridentatus) within 24 h...
