Effects of kelp forest removal on associated fish assemblages in central California
James L. Bodkin
1988, Journal of Experimental Marine Biology and Ecology (117) 227-238
Visual surveys along subtidal belt transects were used to compare fish assemblages on an experimental and a control site before and after the removal of a canopy-forming kelp forest. The giant kelp Macrocystis pyrifera (L.) C.A. Agardh was removed at the holdfast from ≈ 1 ha of high relief structurally complex rock...
Interrelations of oxygen concentrations, fish density, and performance of Atlantic salmon in an ozonated water reuse system
H. A. Poston, R.C. Williams
1988, Progressive Fish-Culturist (50) 69-76
In a 16‐week study, we stocked duplicate groups of 3.3‐g Atlantic salmon (Salmo salar) in 25‐fish increments (25 to 100 fish/6.5‐L jar) and in 250‐fish increments (250 to 1,000 fish/144‐L trough), in an ozonated, 100% closed water reuse system, to examine changes in fish performance in response to rearing at...
Selection for virulence in the fish pathogen Aeromonas salmonicida, using coomassie brilliant blue agar
R. C. Cipriano, J.M. Bertolini
1988, Journal of Wildlife Diseases (24) 672-678
Coomassie Brilliant Blue Agar was used to quantify the frequency of the A-layer phenotype in different isolates of Aeromonas salmonicida. Hydrophilic, non-clumping isolates of A. salmonicida consisted predominantly of the A-layer minus phenotype. These bacteria were avirulent by intraperitoneal injection into susceptible brook trout (Salvelinus fontinalis)...
A reevaluation of the timing and causes of high lake phases in the Lake Michigan basin
A.K. Hansel, D.M. Mickelson
1988, Quaternary Research (29) 113-128
Radiocarbon age control on the type Glenwood, Calumet, and Toleston shoreline features and on the abandoned Chicago outlet at the south end of the Lake Michigan basin provides a basis for reevaluating the timing and causes of high lake phases in the basin. Radiocarbon dates suggest that Glenwood-level (195 m)...
Uranium-series age estimates and paleoclimatic significance of Pleistocene tufas from the Lahontan basin, California and Nevada
Y. Lao, L. Benson
1988, Quaternary Research (30) 165-176
An extended chronology of Lahontan basin lake levels based on uranium-series age estimates correlates with the global ice-volume record. Lake highstands occur at or shortly after times of maximum ice-sheet size. Moderate size lakes occur when the global ice volume is about 80% of its maximum. The data indicate that...

Toxic substances and survival of Lake Michigan salmonids: field and laboratory approaches
Michael J. Mac
Marlene S. Evans, editor(s)
1988, Book chapter, Toxic contaminants and ecosystem health: a Great Lakes focus
An examination is made of the effects of chemical contaminants on the reproduction of fish from the Great Lakes. Routes of contaminant exposure are outlined; andlake trout and chinook salmon mortality are discussed with respect to evidence showing contaminant involvement....
