Windrow composting as an effective method to dispose of large numbers of fish Windrow composting as an effective method to dispose of large numbers of fish
During July 1998, at the USGS Leetown Science Center, Kearneysville, West Virginia, an epizootic occurred in 16-month-old Atlantic salmon (Salmo salar). The cause ofmortality was diagnosed as furunculosis, a serious disease in salmonid fishes caused by the bacterium Aeromonas salmonicida. The fish were being maintained as part ofongoing research and were held in uncovered 30-m-Iong...

New seismic images of the cascadia subduction zone from cruise SO 108-ORWELL New seismic images of the cascadia subduction zone from cruise SO 108-ORWELL
In April and May 1996, a geophysical study of the Cascadia continental margin off Oregon and Washington was conducted aboard the German R/V Sonne. This cooperative experiment by GEOMAR and the USGS acquired wide-angle reflection and refraction seismic data, using ocean-bottom seismometers (OBS) and hydrophones (OBH), and multichannel seismic reflection (MCS) data. The main goal of this...

Analysis of coastal change in Marie Byrd Land and Ellsworth Land, West Antarctica, using Landsat imagery Analysis of coastal change in Marie Byrd Land and Ellsworth Land, West Antarctica, using Landsat imagery
The U.S. Geological Survey is using Landsat imagery from the early 1970s and mid- to late 1980s/early 1990s to analyze glaciological features, compile a glacier inventory, measure surface velocities of outlet glaciers, ice streams and ice shelves, determine coastline change and calculate the area and volume of iceberg calving in Antarctica. Ice-surface velocities in Marie Byrd and...

A comparison of triploid induction validation techniques A comparison of triploid induction validation techniques
Triploidy induction is a technique that allows genetic manipulation of chromosome number to control reproduction and potentially create faster‐growing animals; however, most methods for inducing polyploidy are not 100% effective. Using sunshine bass (white bass Morone chrysops ♀ × striped bass M. saxatilis ♂) as a model, we cross‐validated the most common verification techniques: DNA...

Biochemical and conjugation studies of romet-resistant strains of Aeromonas salmonicida from salmonid rearing facilities in the eastern United States Biochemical and conjugation studies of romet-resistant strains of Aeromonas salmonicida from salmonid rearing facilities in the eastern United States
Strains of Aeromonas salmonicida (n = 585) were collected from covertly infected and diseased salmonid hosts from 12 hatcheries in the eastern United States. Strains and sites were selected because of their potential for harboring antimicrobial resistance, in particular, to Romet™. Resistance to Romet was displayed by 315 strains (53.8%), which were isolated from all six host species...

Control of furunculosis and enteric redmouth disease in sea-run Atlantic salmon broodstock in the Connecticut and Merrimack Rivers Control of furunculosis and enteric redmouth disease in sea-run Atlantic salmon broodstock in the Connecticut and Merrimack Rivers
Adult sea‐run Atlantic salmon Salmo salar captured and transported to Richard Cronin National Salmon Station (Sunderland, Massachusetts), Nashua National Fish Hatchery (Nashua, New Hampshire), and Whittemore State Fish Hatchery (Waterford, Connecticut) during 1986–1992 were treated with oxolinic acid and a bacterin. The bacterin was developed against furunculosis and enteric redmouth...

Evidence for growth hormone/insulin-like growth factor I axis regulation of seawater acclimation in the euryhaline teleost Fundulus heteroclitus Evidence for growth hormone/insulin-like growth factor I axis regulation of seawater acclimation in the euryhaline teleost Fundulus heteroclitus
The ability of ovine growth hormone (oGH), recombinant bovine insulin-like growth factor I (rbIGF-I), recombinant human insulin-like growth factor II (rhIGF-II), and bovine insulin to increase hypoosmoregulatory capacity in the euryhaline teleostFundulus heteroclituswas examined. Fish acclimated to brackish water (BW, 10 ppt salinity, 320 mOsm/kg H2O) were injected with a single dose of...

Identification of Flavobacterinium and Flexibacterin species by species-specific polymerase chain reaction primers to the 16S ribosomal RNA gene Identification of Flavobacterinium and Flexibacterin species by species-specific polymerase chain reaction primers to the 16S ribosomal RNA gene
Species-specific polymerase chain reaction (PCR) primers have been developed for the identification of the causative agents of warmwater and marine finrot in fish: Flavobacterium columnare (Flexibacter columnaris) and Flexibacter maritimus. Differences in gene sequence in the bacterial small-subunit (16S) ribosomal RNA (rRNA) were used to design the species-specific PCR primers. The...
