Se presenta el caso de una mujer no atópica de 42 años de edad que había presentado varios episodios de urticaria generalizada y disnea tras comer marisco, langostinos y percebes, concretamente. La misma paciente había tolerado la ingesta de estos mismos alimentos en múltiples ocasiones entre los distintos episodios de anafi laxia. El estudio alergológico incluyó la realización de pruebas cután...

Addition of nitrite-N at 1.5 mg l(-1) in tryptic soy broth (TSB) significantly (p < 0.05) decreased the growth rate of the bacterial pathogen Lactococcus garvieae and significantly (p < 0.05) reduced mortality compared to zero nitrite controls when injected into giant freshwater prawns Macrobrachium rosenbergii at 5 x 10(5) colony-forming units (CFU) per prawn. In other experiments, whereby pra...

We provide evidence for a trophic cascade involving apex predators and mesopredators of marine temperate reefs, lingcod and rockfish, respectively. We measured spatio-temporal variation in the relative abundance of lingcod, subadult rockfish and two shrimp groups eaten by rockfish (Pandalus sp. and three smaller-bodied genera aggregated). Lingcod had an indirect positive effect on shrimps, as m...

To assess potential indices of nutritional condition, we examined changes in lipid content and the blood refractive index (BRI) of postlarval, juvenile and adult prawns (Penaeus spp.) that had been starved or fed to different levels of satiation. The whole-body lipid content (WBL) of small juvenile P. esculentus (20–120 mg wet weight) decreased significantly after 12 h of starvation. The WBL of...

This study was performed to assess the growth promoting potential of dietary Fe2O3 NPs in Macrobrachium rosenbergii PL. Fe2O3 NPs was supplemented at 0, 10, 20, 30, 40 and 50 mg kg-1 with the basal diet (containing 5.45 mg Iron kg-1). The concentration of Fe in Fe2O3 NPs supplemented diet was increased correspondingly. Fe2O3 NPs supplemented diets were fed to M. rosenbergii PL (initial weight, ...

Effluent water from intensive prawn culture ponds typically has high concentrations of dissolved nutrients such as nitrogen. An experiment was conducted for 28 days to investigate the nitrogen flow where seaweed (Sargassum sp.) was integrated into western king prawn (Penaeus latisulcatus) culture. Three treatments were used, each consisting of four, 0.1m plastic tanks. Treatment 1 and 2 were th...

We will deonstrate the use of (more or less!) Bayesian methods for inferring interaction rules between individuals in a system of collective animal motion. We examine a group of prawns moving in an effectively one-dimensional environment, which we reduce to a binary classification problem, aiming to infer the factors that predict whether an individual will change its direction of motion. Our re...

Semicarbazide (SEM) is the metabolite of the illegal veterinary nitrofurazone (NFZ) in aquatic animal. However there are increasing occurrences that SEM has been found in Macrobrachium Nipponese (M. Nipponese) prawns during the routine quality controls testing for aquatic food in China since 2008. To ascertain the presence and source of SEM, prawn samples were collected from different resources...

the concentrations of cadmium, nickel, lead, and zinc in the four commercial species; silver pomfret(pampus argenteus), king mackerel. (sc0l1l,beromorous commerson), (pomaclasys kaakan), and green tiger prawns (penaeus semisulcatus) were determined in the persian gulf all were collected from the bushir coast. the samples were digested by ultrapure .nitric acid, and then analyzed using the atomi...

This study compares the antioxidant and antimicrobial transcriptional expression of blue shrimps reared according to two different systems, BioFloc Technology (BFT) and Clear sea Water (CW) and their differential responses when facing an experimental sublethal hydrogen peroxide stress. After 30 days of rearing, juvenile shrimps were exposed to H2O2 stress at a concentration of 30 ppm during 6 h...
