Taura syndrome virus (TSV) has caused major economic losses to shrimp aquaculture throughout the world. TSV has been reported to infect a number of penaeid species as hosts. In this study, we reported the natural infection of TSV in farm-reared Penaeus monodon from eastern provinces of Thailand between June to September 2004. There were different degrees of disease outbreak severity. In some ca...

White shrimp Litopenaeus vannamei held in 25x seawater at 27 8C or 28 8C were injected with TSB-grown Vibrio alginolyticus at 1 10 colony-forming units (cfu) shrimp 1 or 1 10 cfu shrimp , and then cultivated onward at water temperatures varying from 20 to 34 8C. Over 24–144 h, mortality of V. alginolyticus-injected shrimp held at 34 8C or 32 8C was significantly higher than that of shrimp held ...

Title of Document: INDIVIDUAL AND POPULATION-LEVEL EFFECTS OF SOLID COAL COMBUSTION RESIDUE ON THE ESTUARINE GRASS SHRIMP (PALAEMONETES PUGIO) Danika M. Kuzmick, Master of Science, 2006 Directed By: Dr. Christopher Rowe, Department of Marine Estuarine and Environmental Science Burning coal for electricity produces solid coal combustion residue (CCR), which is rich in potentially toxic trace ele...

Eyestalk ablation is the most common procedure to induce gonadic maturation in commercial hatcheries of penaeid shrimp. In addition to reproduction, other physiological and metabolic processes are affected by removal of the X-organ sinus gland complex located in the eyestalk. In this study, the effect of unilateral and bilateral eyestalk ablation on the concentration of several hemolymph metabo...

There is currently concern and controversy in the shrimp industries of the Americas about the risk posed by the importation and reprocessing of shrimp infected with white spot syndrome virus (WSSV) and yellow head virus (YHV). To further understand the risk, more knowledge concerning the quantitative virus load of infected shrimp is needed. The present study was carried out to better define, us...

The black tiger shrimp (Penaeus monodon) is a marine crustacean of economic importance in the world market. To ensure sustainability of the shrimp industry, production capacity and disease outbreak prevention must be improved. Understanding healthy microbial balance inside the shrimp intestine can provide an initial step toward better farming practice and probiotic applications. In this study, ...

non-commercial fish species of shrimp trawls were studied monthly from october 2005 to september 2006 in mahshahr creeks (darvish, doragh, bihad, ghazaleh, ghanam, zangi and patil). the trawl nets had a cod-end mesh size of 24mm. total catch was 6431 individuals weighing 55.5kg, and included 14 species of non-commercial fish species belonging to 14 families. the caught shrimp species were from ...
