Passage behavior of radio-tagged yearling Chinook salmon and steelhead at Bonneville Dam, 2004: Revised for corrected spill annual report Passage behavior of radio-tagged yearling Chinook salmon and steelhead at Bonneville Dam, 2004: Revised for corrected spill annual report
Flow augmentation, spill, surface collection, and improved turbine guidance systems have been identified as potential management actions to improve passage efficiency and survival of outmigrating juvenile salmonids. The U.S. Army Corps of Engineers (USACE), along with regional, state, and federal resource agencies, has designed and implemented studies to determine which management...

Fish can get diseases too Fish can get diseases too
Infectious diseases are increasingly recognized as an important component of the ecology of fish in the wild. Many of the viral, bacterial, protozoan and fungal pathogens of fish that were initially discovered in captive fish have their origin among wild populations; however, the impact of disease among these free-ranging stocks has been difficult to study. At the WFRC, combinations of...

Effects of turbidity, light level, and cover on predation of white sturgeon larvae by prickly sculpins Effects of turbidity, light level, and cover on predation of white sturgeon larvae by prickly sculpins
White sturgeon Acipenser transmontanus occur in rivers of the western United States and southwestern Canada, but some populations are in decline because of recruitment failure. Many river systems in this area have been altered as a result of development that has caused major environmental changes. Our goal was to examine how three changes - lower turbidity levels, higher light levels...

Effects of temperature on survival and development of early life stage Pacific and western brook lampreys Effects of temperature on survival and development of early life stage Pacific and western brook lampreys
We examined the effects of temperature (10, 14, 18, and 22??C) on survival and development of Pacific lampreys Lampetra tridentata and western brook lampreys L. richardsoni during embryological and early larval stages. The temperature for zero development was estimated for each species, and the response to temperature was measured as the proportion of individuals surviving to hatch...

Blue tilapia (Oreochromis aureus) predation on fishes in the Muddy River system, Clark County, Nevada Blue tilapia (Oreochromis aureus) predation on fishes in the Muddy River system, Clark County, Nevada
Blue tilapia (Oreochromis aureus), native to North Africa and the Middle East (Courtenay and Robins 1973, Fuller et al. 1999), has been introduced around the world as a human food source, for vegetation control, and as a game fish (Costa-Pierce and Riedel 2000). Blue tilapia has been particularly successful in establishing and spreading in North American waters where it has been reported...

Upstream migration of Pacific lampreys in the John Day River, Oregon: Behavior, timing, and habitat use Upstream migration of Pacific lampreys in the John Day River, Oregon: Behavior, timing, and habitat use
Adult Pacific lamprey migration and habitat preferences for over-winter holding and spawning, and larval rearing in tributaries to the Columbia River are not well understood. The John Day River is one such tributary where larval and adult stages of this species have been documented, and its free-flowing character provided the opportunity to study migration of Pacific lampreys unimpeded...

Total mercury concentrations in fillets of bluegill, redear sunfish, largemouth bass, and other fishes from Lake Natoma, Sacramento County, California Total mercury concentrations in fillets of bluegill, redear sunfish, largemouth bass, and other fishes from Lake Natoma, Sacramento County, California
This study was conducted during September-October 2002 to verify preliminary findings of elevated total mercury concentrations in skinless fillets of sportfishes inhabiting Lake Natoma. Although we measured total mercury concentrations, most mercury in fish flesh occurs in the methylated form. In August 2000, other investigators collected a small number of fish containing mercury...
