River herring—a collective name for the Alewife Alosa pseudoharengus and Blueback
Herring A. aestivalis—play a crucial role in freshwater and marine ecosystems along the …

Background The use of internal telemetry has greatly advanced fisheries research in the
past two decades, permitting researchers to observe movements and distributions of …

Abstract The Atlantic salmon, Salmo salar Linnaeus 1758, is a charismatic, anadromous
species that has faced dramatic declines throughout its range. There is currently a lack of …

Acoustic telemetry is one of the primary technologies for studying the behavior and survival
of fishes throughout the world. The size and performance of the transmitter are key limiting …

Threatened or endangered salmon and steelhead originating in the Snake River basin must
pass through a series of eight major hydroelectric dams during their seaward migration …

Salmonid fish often experience size-selective mortality when descending the river (ie,
seaward migration). However, it is unknown whether size-selective mortality is specific to …

The miniaturization of acoustic transmitters enables researchers to tag smaller fish for
telemetry studies, thus representing a greater proportion of the population of interest. Fish …

Juvenile Pacific Lamprey and American eels were used for laboratory evaluations to
determine potential effects from tag implantation. Telemetry technology has been identified …

The miniaturization of acoustic transmitters may allow greater flexibility in terms of the size
and species of fish available to tag. New downsized injectable acoustic tags similar in shape …

The purpose of this study was to assess the effects of an acoustic micro transmitter (tag) on
survival and swimming ability of juvenile American eels (Anguilla rostrata). The transmitter …
