North Atlantic Vibrio Vulnificus Surveillance From Postharvest Oysters At A Us Shellfish Processing Facility, Kenneth Lavalley, Joseph Dealteris, Michael Rice, Marta Gomez-Chiarri
Marta Gomez-Chiarri
Postharvest surveillance for Vibrio vulnificus by a commercial processing facility was conducted from May 2001 to September 2003. Harvest areas included the Delaware Bay, Long Island Sound and Prince Edward Island. Occurrence followed a seasonal distribution. Low densities were observed in June, increased through August, and became rare by September. Given the ubiquitous nature of marine Vibrios, it was not surprising to find V. vulnificus everywhere, which was investigated. Observations confirmed the importance of strict time/temperature and product handling practices by shellfish harvesters, dealers and processors. Mishandling led to a potentially dangerous and uncharacteristically high V. vulnificus observation.

The yellowfin croaker, Umbrina roncador Jordan & Gilbert, 1882, is a common nearshore and surf-zone species in the southern California bight. Age was determined for individuals (n = 1,209) using annual increments in otoliths, and size at age was modeled using the von Bertalanffy growth curve (L∞ = 307.754 mm, k = 0.278 yr−1, t0 = −0.995 yr; maximum age = 15 yr). Females (L∞= 313.173 mm, k = 0.307 yr−1, t0 = −0.771 yr) grew significantly faster and larger than males (L∞= 298.886, k = 0.269 yr−1, t0 = −1.072 yr). Age and growth modeling based upon otolith length …

Life On The Edge: Morphological And Behavioral Adaptations For Survival On Wave-Swept Shores, Luke P. Miller
Life On The Edge: Morphological And Behavioral Adaptations For Survival On Wave-Swept Shores, Luke P. Miller
Luke P. Miller
Wave-swept rocky shores serve as a home to a great diversity of organisms and are some of the most biologically productive habitats on earth. This burgeoning community exists in spite of the fact that the zone between the high and low tide marks can be one of the most physically harsh environments on earth. Large forces imposed by breaking waves and wide swings in temperature require the organisms living on rocky shores to adapt to a constantly changing environment or risk extirpation by physical forces. I have explored a number of hypothesized adaptations for survival on rocky shores and discuss …

Wind, Waves, And Wing Loading: Their Relative Importance To The At-Sea Distribution And Movements Of North And Central Pacific Albatrosses, R M. Suryan, D J. Anderson, Scott A. Shaffer, D D. Roby, Y Tremblay, D P. Costa, F Sato, K Ozaki, G Balogh
Wind, Waves, And Wing Loading: Their Relative Importance To The At-Sea Distribution And Movements Of North And Central Pacific Albatrosses, R M. Suryan, D J. Anderson, Scott A. Shaffer, D D. Roby, Y Tremblay, D P. Costa, F Sato, K Ozaki, G Balogh

Among the varied adaptations for avian flight, the morphological traits allowing large-bodied albatrosses to capitalize on wind and wave energy for efficient long-distance flight are unparalleled. Consequently, the biogeographic distribution of most albatrosses is limited to the windiest oceanic regions on earth; however, exceptions exist. Species breeding in the North and Central Pacific Ocean (Phoebastria spp.) inhabit regions of lower wind speed and wave height than southern hemisphere genera, and have large intrageneric variation in body size and aerodynamic performance. Here, we test the hypothesis that regional wind and wave regimes explain observed differences in Phoebastria albatross morphology and we …

The Decline And Recovery Of Four Predatory Fishes From The Southern California Bight, Daniel J. Pondella Ii, Larry G. Allen
Daniel Pondella
What to do about fisheries collapse and the decline of large fishes in marine ecosystems is a critical debate on a global scale. To address one aspect of this debate, a major fisheries management action, the removal of gill nets in 1994 from the nearshore arena in the Southern California Bight (34°26′30″N, 120°27′09″W to 33°32′03″N, 117°07′28″W) was analyzed. First, the impetus for the gill net ban was the crash of the commercial fishery for white seabass (Atractoscion nobilis; Sciaenidae) in the early 1980s. From 1982 to 1997 catch remained at a historically low level (47.8 ± 3.0 mt) when compared …
