Toxicity of silver to steelhead and rainbow trout, fathead minnows and Daphnia Magna
Rainbow (Salmo gairdneri) and steelhead (Salmogairdneri) trout and fathead minnows (Pimephales promelas) were exposed to silver for 96 h in replicated flow-through tests. Rainbow trout, fatheadExpand

The life cycle of Ceratomyxa shasta, a myxosporean parasite of salmonids, requires a freshwater polychaete as an alternate host.
The actinosporean life stage of Ceratomyxa shasta, a myxozoan parasite of salmonids, and the annelid worm that serves as its alternate host were identified in laboratory transmission experiments andExpand

Effects of low dissolved oxygen on survival, growth and reproduction of Daphnia, Hyalella and Gammarus
Daphnia magna, Daphnia pulex, Hyalella azteca, and Gammarus lacustris were exposed to low dissolved oxygen concentrations in the laboratory. Acute and chronic exposures were conducted to develop dataExpand

Effect of low dissolved oxygen on aquatic life stages of the caddisfly Clistoronia magnifica (Limnephilidae)
Embryos, larval stages (instars I–V), pupal stages, and pharate adults of the caddisfly Clistoronia magnifica (Limnephilidae) were exposed to a range of dissolved oxygen (DO) concentrations (0.9–8.3Expand

Relationships between Temperature Units and Sensitivity to Handling for Coho Salmon and Rainbow Trout Embryos
Abstract The relationship between embryo development, expressed as cumulative temperature units (TU; the number of TU is the difference between the daily mean temperature and 0°C), and the timing ofExpand
