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 du…
Farmed salmon smolts become more robust and more likely to survive if they undergo optimal aerobic exercise training prior to sea transfer. This was the main message from Chilean Vicente Castro in his doctoral defense in Norway recently.
