Wildlife and electric power transmission
Hundreds of thousands of miles of transmission lines have been introduced into our natural environment. These lines and their corridors can be damaging or beneficial to wildlife communities depending on how they are designed, where they are placed, and when they are constructed and maintained. With the current trend toward UHV systems, new problems (associated with additional increments in audib

Status of the peregrine falcon in the Rocky Mountains and the southwestern United States, Baja California, and Mexico (south of Texas)
About 31 pairs of peregrines still nest north of Mexico, from Idaho and Montana south through West Texas, New Mexico and Arizona. At least thirty-six additional pairs nest in Mexico. Although the nesting sites are occupied, the tissues of the peregrine?s prey species still contain high concentrations of pesticides. The eggs in some Rocky Mountain eyries have shells which are precariously thin and

Spray vaccination: A method for the immunization of fish
An economical, efficacious vaccine delivery system for immunizing fish has been developed which employs a liquid spray apparatus operated at pressures up to 7.0 kg/cm2 (0 to 100 lb/in2). A bacterin consisting of formalin-killed Vibrio anguillarum culture was both antigenic and immunogenic when sprayed on coho salmon(Oncorhynchus kisutch)and rainbow trout(Salmo gairdneri). The technique, referred t

Heritability of tolerance for infectious hematopoietic necrosis in sockeye salmon (Oncorhynchus nerka)
A hierarchical breeding design was used to demonstrate the heritability of tolerance for infectious hematopoietic necrosis (IHN) in sockeye salmon. Oncorhynchus nerka. Heritability was about 30%, indicating that artificial selection may increase the number of fish that can tolerate the disease.

Survival of the salmonid viruses infectious hematopoietic necrosis (IHNV) and infectious pancreatic necrosis (IPNV) in ozonated, chlorinated, and Untreated waters
Ozone and chlorine inactivation curves were determined in three water types at 10 °C for the fish pathogenic viruses infectious hematopoietic necrosis (IHNV) and infectious pancreatic necrosis (IPNV). In phosphate-buffered, distilled water (PBDW) an ozone dose of 0.01 mg/L for 30 or 60 s inactivated IHNV or IPNV, respectively, suspended at a tissue culture 50% infective dose (TCID50) of 104–105/mL

Prevention and treatment of Nitrite toxicity in juvenile steelhead trout (Salmo gairdneri)
The efficacy of mineral salts, pH, and tetramethylthianine (methylene blue) treatment in reducing the acute toxicity of nitrite to fingerling steelhead trout (Salmo gairdneri) was determined using a static bioassay system at 10 °C. The acute toxicity (96-h LC50) was reduced by a factor of about 24 for 5-g steelhead and 13 for 10-g fish when the total water hardness was increased from 25 to 300 mg/
