Effects of Pesticides on DNA and Protein of Shrimp Larvae Litopenaeus stylirostris of the California Gulf

Ecotoxicology and Environmental Safety, 2002
Recently, diverse pathologies and massive mortalities have been presented in shrimp hatcheries located along the California Gulf; therefore, toxic responses of shrimp larvae were used as biomarkers of pesticide pollution, because in this region intensive agriculture is practiced. Shrimp larvae were exposed to DDT, azinphosmethyl, permethrine, parathion,

“Summer Syndrome” in Litopenaeus stylirostris in New Caledonia: Pathology and epidemiology of the etiological agent, Vibrio nigripulchritudo [PDF]

Aquaculture, 2006
The Summer Syndrome is a new shrimp disease that has been affecting a shrimp growout farm in New Caledonia since end of 1997. It was recognized to be caused by a systemic vibriosis due to Vibrio nigripulchritudo. This new disease turned out almost immediately enzootic in the shrimp farm involved and has affected all its crops ever since. Since the year

Molecular epidemiology of Vibrio nigripulchritudo, a pathogen of cultured penaeid shrimp (Litopenaeus stylirostris) in New Caledonia [PDF]

Systematic and Applied Microbiology, 2006
A collection of 57 isolates of Vibrio nigripulchritudo from either diseased or healthy shrimp and from shrimp farms environment was studied in order to gain a better understanding of the epidemiology of this pathogen, notably isolated from two distinct shrimp disease complexes. Molecular typing using two different techniques, arbitrarily primed PCR (AP-

“Summer syndrome” in Litopenaeus stylirostris grow out ponds in New Caledonia: Zootechnical and environmental factors [PDF]

Aquaculture, 2006
The "Summer Syndrome", a septicemic vibriosis caused by Vibrio nigripulchritudo, is responsible for one of the two main seasonal mortalities which affect shrimp aquaculture in New Caledonia. It was identified for the first time in December 1997 in an intensive shrimp farm (called farm DF) and has been enzootic ever since.

Selection and characterization of potential probiotic bacteria for Litopenaeus stylirostris shrimp hatcheries in New Caledonia [PDF]

Aquaculture, 2014
Abstract In New Caledonia, shrimp hatcheries are confronted with mass mortality in the larval stages, a phenomenon poorly understood as no specific causative agent has been identified. This has resulted in an excessive use of prophylactic antibiotics, although their adverse effects in aquaculture are notorious.

Oxygen consumption, ammonium excretion and osmoregulatory capacity of Litopenaeus stylirostris (Stimpson) exposed to different combinations of temperature and salinity

Ciencias Marinas, 2004
The physiological responses of the blue shrimp were determined by exposing the organisms to temperatures of 23ºC, 28ºC and 33ºC, and salinities of 10, 15, 20, 25, 30, 35 and 40‰.

Induction of ovarian maturation and spawning by combined treatment of serotonin and a dopamine antagonist, spiperone in Litopenaeus stylirostris and Litopenaeus vannamei

Aquaculture, 2004
Abstract The study was designed to develop a reliable technique for inducing ovarian maturation and spawning in Litopenaeus stylirostris and Litopenaeus vannamei , as an alternative to the traditional and destructive eyestalk ablation. Two combinations of molecules were evaluated: (a) serotonin (5-HT) at 50 μg g −1 body weight (b.w.)+juvenile ...

Does damming of the Colorado River affect the nursery area of blue shrimp Litopenaeus stylirostris (Decapoda: Penaeidae) in the Upper Gulf of California?

Revista de Biología Tropical, 2000
After damming the Colorado River the freshwater flow was reduced to 1 % of its virgin flow to the Upper Gulf of California (UGC). The ecological effects need to be properly documented.

Postlarval ecology of the blue shrimp (Litopenaeus stylirostris) and brown shrimp (Farfantepenaeus californiensis) in the Colorado River Estuary.

Ciencias Marinas, 2006
The study describes habitat use by penaeid shrimp larvae that enter the Colorado River Delta. A location was chosen in the Santa Clara Channel in the core zone of the Upper Gulf of California and Colorado River Delta Biosphere Reserve, where collections

Effect of sediment on growth and survival of post-larval Litopenaeus stylirostris (Boone, 1931)

Aquaculture Research, 2004
The sediments from four areas that are used or will be used for shrimp culture were evaluated for their effect on post-larvae growth of Litopenaeus stylirostris. Texture, organic matter, total, and bio-available fraction of phosphorus, manganese, iron, zinc, copper, and cadmium of the sediments were measured.
