Early approaches to surgical implantation of electronic tags in fish were often through trial
and error, however, in recent years there has been an interest in using scientific research to …

Energetic tidal-stream environments are characterized by frequent, variable, yet broadly
predictable currents containing ephemeral flow structures that change across multiple spatio …

The risk of effects to fishes and other aquatic life from impulsive sound produced by activities
such as pile driving and seismic exploration is increasing throughout the world, particularly …

Freshwater fishes are one of the most imperiled groups of vertebrates, and population
declines are alarming in terms of biodiversity and to communities that rely on fisheries for …

Environmentally enhanced hydroelectric turbines have been developed to reduce injury and
mortality of downstream-migrating fishes and to improve downstream water quality …

A proportion of juvenile Chinook salmon Oncorhynchus tshawytscha and other salmonids
travel through one or more turbines during their seaward migration in the Columbia and …

Fish can be injured or killed during turbine passage. This paper reports the first in-situ
evaluation of hydraulic conditions that fish experienced during passage through Francis …

Barotrauma-injuries sustained following rapid decompression occur in many different
fisheries applications. Previous attempts to quantify barotrauma in fish have been limited by …

On their seaward migration, juvenile salmonids commonly pass hydroelectric dams. Fish
passing by the turbine blade may experience rapid decompression, the severity of which …

Stock assessment methods for Pacific salmon (Oncorhynchus spp.) require estimates of total
mortality to obtain accurate exploitation rate and stock size estimates. Total mortality …
