Passage efficiency of adult Pacific lampreys at hydropower dams on the lower Columbia River, USA
Abstract Hydropower dams in the lower Columbia River may contribute to declines in the populations of anadromous Pacific lamprey Lampetra tridentata by limiting access to historical spawningExpand
Use of an extensive radio receiver network to document Pacific lamprey (Lampetra tridentata) entrance efficiency at fishways in the Lower Columbia River, USA
We used an extensive network of more than 170 radio receiving stations to document fine-scale passage efficiency of adult anadromous Pacific lamprey at Bonneville and The Dalles Dams in the lowerExpand
Population Status of North American Green Sturgeon, Acipenser medirostris
North American green sturgeon, Acipenser medirostris, was petitioned for listing under the Endangered Species Act (ESA). The two questions that need to be answered when considering an ESA listingExpand
Effects of Body Size and River Environment on the Upstream Migration of Adult Pacific Lampreys
A half-duplex passive integrated transponder (PIT) tag monitoring array at five Columbia and Snake River dams was developed to evaluate adult lamprey migrations and indicated high attrition as lampreys progressed upstream. Expand
Primary factors affecting sturgeon populations in the Southeastern United States : Fishing mortality and degradation of essential habitats
Proposed management strategies aimed at conservation and restoration of sturgeon populations focus on protection of essential habitats and establishment of reserves to provide protection from fishing gears that generate substantial sturgeons by-catch. Expand
A Protocol for Use of Shortnose and Atlantic Sturgeons
This document reviews the most acceptable methods for short-term holding, identification and measurement, tagging, tissue sampling, gastric lavage, and collection using a variety of gear types and establishes a protocol for sampling to establish whether shortnose sturgeon are present in systems where their status is unknown.

Infection of American Eels, Anguilla rostrata, by an Introduced Nematode Parasite, Anguillicola crassus, in North Carolina
The infection rate of North Carolina eels was substantially higher than that reported in Chesapeake (10–29%) and Hudson River (0–12%) collections, and the fact that this exotic may have been introduced earlier in southern rivers than in northern ones may be related to increased warm water periods in northern rivers.

Improving Passage Efficiency of Adult American Shad at Low-Elevation Dams with Navigation Locks
Abstract Use of navigation locks represents a low-cost alternative to the construction of fishways or lifts at low-elevation (<5 m) dams. We used sonic tracking to assess the passage efficiency ofExpand
Similarities, Differences, and Unknowns in Biology and Management of Three Parasitic Lampreys of North America
This work identifies areas in which key information is missing for the juvenile (parasitic feeding) phase and adult freshwater spawning migrations, and compares and contrast information for anadromous sea and Pacific lampreys. Expand
