Research by Egil Karlsbakk, et al, Institute of Marine Research, Norway, has found that ballan wrasse may host P. perurans infections. Wrasse may therefore also play a possible role in the epizootiology of Amoebic Gill Disease (AGD) in salmonids.
Global fisheries are overexploited worldwide, yet crucial catch statistics reported to the Food and Agriculture Organisation (FAO) by member countries remain unreliable. Recent advances in remote-sensing technology allow fishing practices to be viewed from spa…
Non-tuberculous mycobacteria responsible for piscine mycobacteriosis usually produce visceral granulomas in both freshwater and marine species. In this study by Elisabetta Antuofermo et al, University of Sassar, Italy, the first occurrence of Mycobacterium che…
Kelp ecosystems form widespread underwater forests playing a major role in structuring the biodiversity at a regional scale. Some seaweeds such as Laminaria digitata are also economically important, being exploited for their alginate and iodine content. Virgin…
