Parasitology meets ecology on its own terms: Margolis et al. revisited.
TLDR
Suggestions for various terms used by parasitologists when describing the ecology of parasites are provided in an attempt to foster consistent use and to make terms used in parasite ecology easier to interpret for those who study free-living organisms. Expand
Selective breeding of Pacific white shrimp (Litopenaeus vannamei) for growth and resistance to Taura Syndrome Virus
TLDR
From 1995 to 1998, the Oceanic Institute operated a breeding program for Pacific white shrimp based on a selection index weighted equally for growth and resistance to Taura Syndrome Virus, which resulted in select shrimp from the Growth line being 21% larger than unselected control shrimp. Expand
Disease will limit future food supply from the global crustacean fishery and aquaculture sectors.
TLDR
The linking together of global experts in the culture, capture and trading of crustaceans with pathologists, epidemiologists, ecologists, therapeutics specialists and policy makers in the field of food security will allow these issues to be better identified and addressed. Expand
Reproductive Biology of Cobia, Rachycentron canadum, from Coastal Waters of the Southern United States
Abstract— Reproductive biology of the cobia, Rachycentron canadum , is de-scribed from four coastal areas in the southern United States. Samples were obtained from recreational fi shermen betweenExpand
Water quality dynamics and shrimp (Litopenaeus vannamei) production in intensive, mesohaline culture systems with two levels of biofloc management
TLDR
The results of this study demonstrate engineering and management decisions that can have important implications for both water quality and shrimp production in intensive, minimal-exchange culture systems. Expand
The role of positive and negative interspecific associations in the organization of communities of intestinal helminths of bats.
TLDR
Positive interactions are more common than negative interactions in determining the species richness of helminth infracommunities of bats, and positive associations become even more important as the community becomes more complex. Expand

The greatest threat to the future of world shrimp aquaculture is disease, in particular the virulent untreatable viruses, infectious hypodermal and haematopoietic necrosis virus (IHHNV), tauraExpand
Epidemiological parameters of White Spot Syndrome Virus infections in Litopenaeus vannamei and L. setiferus.

  • 1 July 2001
TLDR
An experimental protocol based on a mathematical epidemiology model was developed to study the transmission, virulence, and recovery rates of White Spot Syndrome Virus (WSSV) in Litopenaeus vannamei, finding the epidemic threshold density may be lower for ingestion transmission than cohabitation transmission and lower for L. setiferus. Expand
Time course of necrotizing hepatopancreatitis (NHP) in experimentally infected Litopenaeus vannamei and quantification of NHP-bacterium using real-time PCR.
TLDR
The percent of hepatopancreatic tubules containing NHPB in epithelial cells increased over time, representing bacteria multiplication and spread in NHP, a severe bacterial disease affecting penaeid shrimp aquaculture. Expand
Gonadal Maturation in the Cobia, Rachycentron canadum, from the Northcentral Gulf of Mexico
TLDR
Gonadal maturation of cobia, Rachycentron canadum, was evaluated by examining 508 specimens from its recreational fishery and it was determined that females were ripe from May through September, with atretic oocytes occurring in some fish from July through October. Expand
