Populations of Pacific lamprey Lampetra tridentata have declined in the Columbia River basin. One factor that may contributed to this reduction population size is an excessive use energy by adult lampreys as they negotiate fishways at dams during spawning migrations. To gain understanding performance capacity lampreys, we estimated critical swimming speed (Ucrit) and documented physiological responses radio-tagged untagged exercised exhaustion. The mean (±SD) Ucrit was 86.2 ± 7.5 cm/s 15°C,...
Abstract We examined the effects of temperature (10, 14, 18, and 22°C) on survival development Pacific lampreys Lampetra tridentata western brook L. richardsoni during embryological early larval stages. The for zero was estimated each species, response to measured as proportion individuals surviving hatch, stage, exhibiting abnormalities at stage (i.e., malformations body). 4.85°C 4.97°C lampreys. Survival greatest 18°C, followed by 10, 22°C, significant differences being observed between...
Abstract Pacific lampreys Lampetra tridentata are in decline throughout much of their historical range the Columbia River basin. In support restoration efforts, we tested whether larval and adult lamprey bile acids serve as migratory spawning pheromones lampreys, they do sea Petromyzon marinus . The olfactory sensitivity to was measured by electro‐olfactogram recording from time capture spring until June following year. As controls, L‐arginine a non‐lamprey acid, taurolithocholic acid...
Understanding trends in the diverse resources provided by large rivers will help balance tradeoffs among stakeholders and inform strategies to mitigate effects of landscape scale stressors such as climate change invasive species. Absent a cohesive coordinated effort assess important river resources, logical starting point is our ability draw inferences from existing efforts. In this paper, we use common analytical framework analyze data five disparate fish monitoring programs better...
Abstract The general morphology and precision associated with age determination of statoliths from larval Pacific lampreys Lampetra tridentata western brook L. richardsoni found within the Columbia River basin were examined. Significant positive correlations observed between size left right individuals. Principal components analysis indicated an allometric relationship lamprey length statolith as well a potential species grouping based on these measurements. Discriminant was able to...
Abstract In business, benchmarking is a widely used practice of comparing your own business processes to those other comparable companies and incorporating identified best practices improve performance. Biologists resource managers designing conducting monitoring programs for fish in large river systems tend focus on single basins or segments rivers, missing opportunities learn from rivers. We briefly examine five long-term rivers the United States (Colorado, Columbia, Mississippi, Illinois,...
The northern pikeminnow Ptychocheilus oregonensis is a large, native cyprinid in the Columbia River basin that has persisted spite of substantial habitat alterations. During months June to September 1993–1996, we investigated temporal and spatial patterns spawning, along with describing larval drift characterizing early juvenile rearing habitats lower (the John Day Dalles reservoirs free-flowing section downstream Bonneville Dam) as well sections two major tributaries Deschutes rivers)....
Abstract We examined the survival, tag retention, and growth of Pacific lamprey Lampetra tridentata larvae macrophthalmia marked with standard‐length decimal coded wire tags exposed to two levels handling stress. The survival individuals did not differ from that unmarked at either life stage for duration experiment (56 d). Tag retention was 100% all treatment combinations except were handled frequently (93 ± 3%). majority loss occurred within 28 d marking, no observed between 42 56 after...
Abstract The effectiveness of morphometric and meristic characteristics for taxonomic discrimination Lampetra tridentata L. richardsoni (Petromyzonidae) during embryological, prolarval, early larval stages (i.e., age class 1) were examined. Mean chorion diameter increased with time from fertilization to hatch was significantly greater than at 1, 8, 15 days postfertilization. larvae had more trunk myomeres ; however, myomere numbers highly variable within species deviated previously published...
Despite substantial research and conservation efforts, many salmon populations are in decline. Globally, is not delivering effective decision support products to help managers apply insights as informed management actions. Data Mobilization (DM) a key step towards building the wider evidence base required deliver accountable, reliable, usable scientific advice managers. Best practices for DM being adopted throughout community but have permeated deeply into culture of conservation. To address...
