The purpose of this study was to quantify the gene expression of lysozyme, an important antibacterial protein produced by shrimp hemocytes, within tissues of Litopenaeus vannamei Boone in response to a pathogen challenge. We quantified lysozyme transcripts with a real-time PCR method and used these data, along with total hemocyte counts, to infer patterns(More)
The striped bass (Morone saxatilis) is an economically and ecologically important finfish species along the Atlantic seaboard of the United States. Recent stock assessments in Chesapeake Bay (U.S.A.) indicate that non-fishing mortality in striped bass has increased since 1999, concomitant with very high (>50%) prevalence of visceral and dermal disease(More)
groupers and their associated reef fish assemblage near cape fear, north carolina, were observed using scuba and underwater stationary videography during a 7-mo period. fifty-seven sites were visited with stationary video and diver point counts of groupers were taken at each site. primary observations by both techniques were made on gag, Mycteroperca(More)
White spot syndrome virus (WSSV) is a prevalent and virulent pathogen affecting both wild and cultured penaeid shrimp worldwide. Molecular diagnostic tools have made detection of the virus increasingly accurate. However, these techniques are often not readily available for rapid diagnosis in the field or in shrimp production facilities. Shrimple®, an(More)
Peroxinectin (Pox), which promotes cell adhesion and encapsulation of bacteria in crustaceans, is synthesized in granular and semigranular hemocytes. In this study, real-time PCR was used to quantify Pox transcripts in individual tissues of the Pacific white shrimp, Litopenaeus vannamei, over 48 h following injection of a sublethal dose of the shrimp(More)
Heavy metals, such as copper, zinc and cadmium, represent some of the most common and serious pollutants in coastal estuaries. In the present study, we used a combination of linear and artificial neural network (ANN) modelling to detect and explore interactions among low-dose mixtures of these heavy metals and their impacts on fundamental physiological(More)
White spot syndrome virus (WSSV) is a virulent pathogen of cultured shrimp and was first detected in farms in South Carolina (USA) in 1997 and subsequently in wild shrimp in 1999. We screened groups of 1808 wild Atlantic white shrimp Litopenaeus setiferus and 300 blue crabs Callinectes sapidus collected from South Carolina, Georgia, and Florida for the(More)
The rhizocephalan barnacle Loxothylacus panopaei is a parasitic castrator of xanthid crabs that has invaded the U.S. Atlantic coast. It was transported to the Chesapeake Bay in the mid-1960s with mud crabs associated with Gulf coast oysters and has since spread north to Long Island Sound, New York, and south to Cape Canaveral, Florida. Here we report(More)
The urchin Diadema antillarum Philippi (Echinodermata: Echinoidea) was extremely rare to absent from reefs throughout Jamaica during much of the 1980s and part of the 1990s following a Caribbean wide mortality event. This survey was conducted in 2007 to assess their distribution on the western forereef of Discovery Bay, Jamaica. Mean urchin densities of(More)
