Monitoring regional effects of high pressure injection of wastewater in a limestone aquifer
More than 10 billion gallons (38 × 106 m3) of acid industrial liquid waste has been injected in about 11 years under high pressure into a saline-water-filled part of a limestone aquifer of low transmissivity between 1,400 and 1,700 feet (430 and 520 m) below land surface near Pensacola, Florida. A similar waste disposal system is planned for the same zone at a site about 8.5 miles (13.7 km) to the

Detection and transmission of infectious hematopoietic necrosis virus in rainbow trout
Detection and transmission of Infectious Hematopoietic Necrosis Virus in rainbow trout (Salmo gairdneri) was studied at a commercial trout hatchery. Transmission of virus was demonstrated via water, feed and contaminated eggs. If eggs from carrier females were incubated several weeks in virus-free water, the resulting fry did not become infected. However, if fry subsequently became infected they w

Changes in the lake trout population of southern Lake Superior in relation to the fishery, the sea lamprey, and stocking, 1950-70
Commercial catch and effort statistics for 1929-70, samples of commercial catches in 1959-62, and records of examinations of all lake trout (Salvelinus namaycush) taken commercially in inshore waters of Michigan and Wisconsin in 1962-70 were the basis for descriptions of changes in the population in 1929-70.
Abundance fluctuated cyclically and gradually downward in 1929-49, whereas fishing intensi
