Megalocytivirus is causing economically serious mass mortality by infecting fish in and around the Pacific region of Asia. The recent emergence of many new iridoviruses has drawn attention to the marked taxonomic variation within this virus family. Most studies of these viruses have not included extensive study of these emergent species. We explored the emergence of red sea bream iridovirus (RS...

in this paper, a photonic crystal waveguide with point defects and lattice constant perturbations of +5%, -5% are being investigated. firstly waveguide structures with constant and specific parameters are being studied and photonic band gap diagrams for te/tm modes are depicted; then pulse propagation in the frequencies available in the band gap are shown. after that, effects of parameters like...

Blind tests were conducted to evaluate the taste and sensory properties of orange-cultured red sea bream (OCRSB). OCRSB belly was rated statistically higher than regular back for three items: total, color, smell. An analysis by sex showed that color smell significantly males females. country origin several items related or Chinese Japanese OCRSB.

the japanese threadfin bream, nemipterus japonicus, the most abundant and crucially economic nemipterus species is widespread throughout the indo-west pacific. the species has been studied widely for various aspects but genetic studies are scanty. this preliminary study contributes to the species phylogeography through the study of the genetic diversity and historical demography of n. japonicus...

the present study tried to investigate the effects of probiotic, pediococcus acidilactici in concentrations of 1× 109, 2× 109 and 3×109cfu kg-1 diet on growth and survival rate of oriental bream fry (abramis brama orientalis, berg 1949) in comparison to control diet (devoid of probiotic) for 60 days. in so doing, 180 specimens of oriental bream with initial weight of 2.69± 0.22 g were divided r...

Abstract Due to the complexity of deterioration process seafood products, relying on one indicator is not adequate determine quality such products. Usually, shelf-life was estimated based various indicators complicating decision-making process. Decision Support Systems are considered as a good solution. The current study aims establish simple and novel fuzzy model combination knowledge- data-dr...

On-growing juveniles of gilthead sea bream were acclimated for 45 days to mild-hypoxia (M-HYP, 40–60% O2 saturation), whereas normoxic fish (85–90% saturation) constituted two different groups, depending on if they fed visual satiety (control fish) or pair-fed M-HYP fish. Following the hypoxia conditioning period, all maintained in normoxia and continued be until satiation 3 weeks. The time cou...

To gain a better understanding of which pharmaceuticals could pose risk to fish, 94 representing 23 classes were analyzed in blood plasma from wild bream, chub, and roach captured at 18 sites Germany, the Czech Republic UK, respectively. Based on read across humans, we evaluated risks pharmacological effects occurring fish for each measured pharmaceutical. Twenty-three compounds found plasma, w...
