A natural epizootic of infectious haematopoietic necrosis in imported Atlantic salmon, Salmo salar L., reared in the enzootic region A natural epizootic of infectious haematopoietic necrosis in imported Atlantic salmon, Salmo salar L., reared in the enzootic region
In June 1984, fry of Atlantic salmon, Salmo salar L., (0-3 g mean weight), being reared in a hatehery operated by the University of Washington, began to die and infectious haematopoietic necrosis (IHN) was diagnosed. A total of 40 000 fry were being held in 11 tanks. Mortality due to IHN was noticeable in three tanks, losses being heavy in one and moderate in two. Gross examination of...

Comparison of species composition and richness of fish assemblages in altered and unaltered littoral habitats Comparison of species composition and richness of fish assemblages in altered and unaltered littoral habitats
Species composition and richness of fish assemblages in altered and unaltered littoral habitats in Lake St. Clair, Michigan, differed between areas. A percid-cyprinid-cyprinodontid assemblage dominated in the unaltered area, Muscamoot Bay, which has a natural shoreline (with almost no alteration due to dredging or bulkheading), high water quality, and high species richness of aquatic...

Susceptibility of progeny from crosses among three stocks of coho salmon to infection by Ceratomyxa shasta Susceptibility of progeny from crosses among three stocks of coho salmon to infection by Ceratomyxa shasta
Crossbred coho salmon Oncorhynchus kisutch were produced from all possible crosses among three stocks. The relative susceptibility of the progeny to infection by the myxosporean parasite Ceratomyxa shasta was determined by exposure of juvenile fish to Willamette River water that contained the infective stage of the parasite. Susceptibility of coho salmon native to the Columbia River...

Family size and effective population size in a hatchery stock of coho salmon (Oncorhynchus kisutch) Family size and effective population size in a hatchery stock of coho salmon (Oncorhynchus kisutch)
Means and variances of family size measured in five year-classes of wire-tagged coho salmon (Oncorhynchus kisutch) were linearly related. Population effective size was calculated by using estimated means and variances of family size in a 25-yr data set. Although numbers of age 3 adults returning to the hatchery appeared to be large enough to avoid inbreeding problems (the 25-yr mean...

Parasite burdens in experimental families of coho salmon. Parasite burdens in experimental families of coho salmon.
We examined the possibility that parasites affect survival rates of anadromous hatchery coho salmon Oncorhynchus kisutch during their period in the wild. Survival was estimated from the rates at which adults returned to the hatchery. The frequency of infection of heart tissue by metacercariae of Nanophyetus sp. was higher in individuals from families with relatively high survival...
