By sampling individual rainbow trout, Oncorhynchus mykiss, at a fish farm we showed that Argulus coregoni were aggregated within their host population. The relative significance of susceptibility and exposure generating the observed pattern was tested using experimental infections. We examined, whether rainbow trout developed protective resistance mechanisms against the louse following a challe...

Excessive accumulation of carcass fat in farm animals, including fish, has a significant impact on meat quality and on the cost of feeding. Similar to farmed animals and humans, the liver can be considered one of the most important organs involved in lipid metabolism in rainbow trout (Oncorhynchus mykiss). RNA-seq based whole transcriptome sequencing was performed to liver tissue of rainbow tro...

BACKGROUND There have been an increasing number of infections in fish associated with different species of Chryseobacterium, being considered potentially emerging pathogens. Nevertheless the knowledge of the diversity of species associated with fish disease is partial due to the problems for a correct identification at the species level based exclusively on phenotypic laboratory methods. RESU...

Studies were conducted to determine the pathogenicity for European eels Anguilla anguffla and rainbow trout Oncorhynchus mykiss of several stra~ns of the species Aeromonas hydrophila, A. jandaei, A. sobria, A. caviae. Plesiomonas shigelloides. Vibrio anguillarum, Pseudomonas fluorescens and Shewanella putrefaciens isolated from an eel farm. Virulence of 20 isolates obtained during epizootics fr...

Excessive nutrients in aquaculture effluent have become an alarming environmental issue. However, current treatment methods for recovering are ineffective since the contains trace amounts of nutrients. Pressure-driven nanofiltration (NF) is a potential solution to problem low concentration gradient. In this work, NF was applied concentrate and recover (ammonium (NH4+), phosphate, (PO43-), nitra...
