Concentrations of 160 polychlorinated biphenyl (PCB) congeners or congener groups were determined in approximately 600 farmed Atlantic salmon from around the world and wild (ocean-caught) Pacific salmon from the Northeast Pacific. Concentrations and PCB congener profiles were analyzed to provide insight into the sources and uptake of PCBs in salmon as well as regional differences. Although tota...

edwardsiella tarda is a versatile pathogen that could survive in different environmental conditions and infect economically important fish species. the whole cell antigenic proteins were extracted from e. tarda and assessed via western blot using anti e. trada rohu and anti e. trada rabbit serum. two strong reacted proteins with antibodies were recovered viz 61 kda and 47 kda from sds page gels...

Background: Sea foods contain high level of unsaturated fatty acids. The aim of this study is comparison of ώ3 and ώ6 levels in wild and farmed green tiger shrimp (P.semisulcatus). Materials and Methods: in this study 120 shrimps (wild=60 and farmed=60) selected. Analysis of Fatty acids was performed by Gas Chromatography. Two-factor variance difference analysis used for demonstration the effec...

The conditions encountered by Atlantic salmon, Salmo salar L., in aquaculture are markedly different from the natural environment. Typically, farmed salmon experience much higher densities than wild individuals, and may therefore have adapted to living in high densities. Previous studies have demonstrated that farmed salmon typically outgrow wild salmon by large ratios in the hatchery, but thes...

1 Former human practices can persistently influence forest ecosystems, particularly by altering the distribution and abundance of vegetation. Previous research has focused on the role of colonization success in governing plant community patterns in abandoned forests, but few studies have explored how changes in the performance of adult plants may contribute to changes in plant populations. 2 We...

The eating quality characteristics of farmed and wild Atlantic salmon, from locations in and around Northern Ireland, were compared by sensory analysis of frozen salmon. Quantitative descriptive analysis, using a trained panel, was used to compare specific attributes, while an untrained panel used hedonic scaling methods to assess acceptability. Freezing affected texture and appearance but had ...

Fisheries catches worldwide have shown no increase over the last two decades, while aquaculture has been booming. To cover the demand for fish in the growing human population, continued high growth rates in aquaculture are needed. A potential constraint to such growth is infectious diseases, as disease transmission rates are expected to increase with increasing densities of farmed fish. Using a...

The present work was conducted to compare the occurrence of Escherichia coli possessing virulence and ESBL genes in backyard and farmed poultry. Three hundred and sixty samples from the poultry kept in backyard system and 120 samples from the farmed birds were collected from West Bengal, India. Among the E. coli isolates of backyard poultry (O2, O10, O25, O55, O60, O106, UT), none of them posse...
