White sturgeon (Acipenser transmontanus) passage at the Dalles Dam, Columbia River, USA White sturgeon (Acipenser transmontanus) passage at the Dalles Dam, Columbia River, USA
White sturgeon (Acipenser transmontanus) ???95 cm TL were monitored using acoustic and radio telemetry at a large hydroelectric dam (the Dalles Dam) on the Columbia River, during March 2004 through November 2005 to determine timing and routes of passage and to characterize general movements. Transmitters were surgically implanted into 148 fish during the study; 90 were released into the...

Bypass system modification at Bonneville Dam on the Columbia River improved the survival of juvenile salmon Bypass system modification at Bonneville Dam on the Columbia River improved the survival of juvenile salmon
From 1987 to 1992, we evaluated a fish bypass system at Bonneville Dam Powerhouse 2 on the Columbia River. The survival of subyearling Chinook salmon Oncorhynchus tshawytscha released into the system ranged from 0.774 to 0.911 and was significantly lower than the survival of test fish released into turbines and the area immediately below the powerhouse where bypass system flow reentered...

Genotyping of Korean isolates of infectious hematopoietic necrosis virus (IHNV) based on the glycoprotein gene Genotyping of Korean isolates of infectious hematopoietic necrosis virus (IHNV) based on the glycoprotein gene
Glycoprotein (G) gene nucleotide sequences of four Korean isolates of infectious hematopoietic necrosis virus (IHNV) were analyzed to evaluate their genetic relatedness to worldwide isolates. All Korean isolates were closely related to Japanese isolates of genogroup JRt rather than to those of North American and European genogroups. It is believed that Korean IHNV has been most likely...

Genotypes and phylogeographical relationships of infectious hematopoietic necrosis virus in California, USA Genotypes and phylogeographical relationships of infectious hematopoietic necrosis virus in California, USA
Infectious hematopoietic necrosis virus (IHNV) contains 3 major genogroups in North America with discreet geographic ranges designated as upper (U), middle (M), and lower (L). A comprehensive genotyping of 237 IHNV isolates from hatchery and wild salmonids in California revealed 25 different sequence types (a to y) all in the L genogroup; specifically, the genogroup contained 14 sequence...

Effects of antenna length and material on output power and detection of miniature radio transmitters Effects of antenna length and material on output power and detection of miniature radio transmitters
The optimal antenna of transmitters used in small aquatic animals is often a compromise between efficient radio wave propagation and effects on animal behavior. Radio transmission efficiency generally increases with diameter and length of the conductor, but increased antenna length or weight can adversely affect animal behavior. We evaluated the effects of changing antenna length and...

WFRC patrners: our extended family WFRC patrners: our extended family
For more than five decades the Western Fisheries Research Center (WFRC) has worked with partners to provide research findings to managers of aquatic resources. Those partners form an extended family, a network of clients, colleagues, co-investigators, and customers. Our partners include numerous clients in other Department of Interior bureaus such as the U.S. Fish and Wildlife Service...

Pre-Restoration Habitat Use by Chinook Salmon in the Nisqually Estuary Using Otolith Analysis Pre-Restoration Habitat Use by Chinook Salmon in the Nisqually Estuary Using Otolith Analysis
INTRODUCTION The Nisqually Fall Chinook population is one of 27 stocks in the Puget Sound evolutionarily significant unit listed as threatened under the federal Endangered Species Act. The preservation of the Nisqually delta ecosystem coupled with extensive restoration of approximately 1,000 acres of diked estuarine habitat is identified as the highest priority action for the recovery of
