Isolates of the most commonly observed salmonella serovars in Norwegian fish feed factories from 1998 to 2000 (Salmonella enterica serovar Agona, S. enterica serovar Montevideo, S. enterica serovar Senftenberg, and S. enterica serovar Kentucky) were studied by pulsed-field gel electrophoresis (PFGE) and plasmid profile analysis and compared to isolates of the same serovars from fish feed ingred...

on the basis of the some studies recently published on the concentration of potentially dangerous levels of mercury, a global pollutant and highly toxic element in sea fish and specially tuna fish, this work has been carried out to determine the concentration of mercury in canned tuna fish, that compose a large majority of the fish most people eat. for this reason, 30 cans, produced by differen...

The position of genes in the interphase nucleus and their association with functional landmarks correlate with active and/or silent states of expression. Gene activation can induce chromatin looping from chromosome territories (CTs) and is thought to require de novo association with transcription factories. We identify two types of factory: "poised transcription factories," containing RNA polym...

Fish-meal factories generate waste waters with high chemical oxygen demand (COD), suspended solids (SS), fats and protein concentrations. After their treatment by anaerobic digestion, effluents with high ammoniaand organic-nitrogen contents and a fraction of residual COD are produced. A biological nitrification/denitrification process is proposed to reduce both the residual carbon and the nitro...

Anchovy (Engraulis encrasicolus L., 1758) is the main source of fishmeal in Turkey. The research was carried out 3 factories where anchovy processed Black Sea during 2007-2008 fishing season. Factories A and B have an evaporator system, while factory C does not system. In study, it aimed to reveal effect system on mineral substance quality produced oil factories. As a result this elements are l...

Piscine orthoreovirus (PRV) is associated with heart- and skeletal muscle inflammation in farmed Atlantic salmon. The virus is ubiquitous and found in both farmed and wild salmonid fish. It belongs to the family Reoviridae, closely related to the genus Orthoreovirus. The PRV genome comprises ten double-stranded RNA segments encoding at least eight structural and two non-structural proteins. Ery...
