Effect of vitamin E on the immune response of channel catfish to Edwardsiella ictaluri Effect of vitamin E on the immune response of channel catfish to Edwardsiella ictaluri

Three-month-old fingerling channel catfish Ictalurus punctatus were fed purified diets supplemented with ∝-tocopherol acetate to provide 0, 60, and 2,500 mg vitamin E/kg for 180 d. A 30-s immersion bath and an oral booster were used to deliver a bacterin of formalin-killed Edwardsiella ictaluri to half of the fish from each dietary treatment. Resistance of red blood cells to peroxidation...

Calibration of the BASS acoustic current meter with carrageenan agar Calibration of the BASS acoustic current meter with carrageenan agar

The BASS current meter can measure currents down to the millimeter per second range. Due to the dependence of zero offset on pressure, determining a sensor referenced velocity requires accurate in situ zeroing of the meter. Previously, flow was restricted during calibration by placing plastic bags around the acoustic volume. In this paper, bacterial grade and carrageenan agars are used...

Observations of currents and density structure across a buoyant plume front Observations of currents and density structure across a buoyant plume front

Observations of the Mobile Bay, Alabama, plume during a flood event in April 1991 reveal significant differences in the current field on either side of a front associated with the buoyant plume. During a strong southeasterly wind, turbid, low salinity water from Mobile Bay was pushed through an opening in the west side of the ebb-tidal delta and moved parallel to the coast. A stable...

Mesozoic stratigraphy and paleoenvironments of the Georges Bank Basin: A correlation of exploratory and cost wells Mesozoic stratigraphy and paleoenvironments of the Georges Bank Basin: A correlation of exploratory and cost wells

The Exxon 975-1, Conoco 145-1, and Mobil 312-1 hydrocarbon exploratory wells and the Continental Offshore Stratigraphic Test (COST) G-1 and G-2 wells were drilled in the southeastern part of the Georges Bank Basin. We used drill cuttings and logs from these wells to describe and correlate the dominant lithostratigraphic units and to document lateral changes in the depositional...

Processes affecting coastal wetland loss in the Louisiana deltaic plain Processes affecting coastal wetland loss in the Louisiana deltaic plain

Nowhere are the problems of coastal wetland loss more serious and dramatic than in the Mississippi River deltaic plain region of south-central Louisiana. In that area, rates of shoreline erosion of 20 m.yr and loss of land area of up to 75 km/yr result from a complex combination of natural (delta switching, subsidence, sea-level rise, storms) and human (flood control, navigation, oil and...
