New approach could improve understanding of farmed seabream welfare
Analyzing proteins from the skin mucus of gilthead seabream (Sparus aurata) could offer a promising, welfare-friendly route to monitor stress levels of the fish during production cycles.
Warming climate could mean more-virulent fish viruses, study suggests
Rising temperatures may increase the risk that viral pathogens pose to farmed seafood species, according to French research.
Novel sampling reveals microbial changes during gill disease on Irish salmon farm
A non-lethal sampling method combined with cutting-edge molecular analysis has shed new light on microbial interactions in Atlantic salmon gills during a gill disease outbreak.
Environmental DNA testing could provide early warning of barramundi disease
Sampling DNA from the aquaculture environment could aid early diagnosis of scale drop disease, an emerging and potentially severe viral condition affecting farmed barramundi in Asia.
Stomach-resistant oral vaccines could offer fish farmers easier vaccine administration
Oral vaccines hold a great deal of promise for fish farmers. Easier and quicker to administer than injected vaccines, they are also potentially suitable for fish that are too small for injection vaccination, including larval stages.
Molecular testing sheds new light on troublesome microorganism which threatens fish
A new molecular approach has revealed the ubiquitous and opportunistic nature of Saprolegnia parasitica, a fungal-like microorganism that can cause significant disease and economic loss.
The future of sea louse control on salmon farms: do genetic technologies hold the key?
Genetic technologies could give salmon farmers the crucial tools they need to prevent sea louse infestations, according to researchers.
Revealing farmed sea bream’s diverse microbiome could aid health improvements
The microbiome of gilthead seabream farmed in the Mediterranean appears to be very distinct from that of their surrounding environment — offering new insight which may help in managing health issues associated with the species.
How to balance fish welfare and environmental protection in aquaculture
Fish farmers’ efforts to protect the environment often come at a cost to fish welfare, say scientists at the University of Melbourne, in a new opinion paper.
Columnaris disease affects Nile tilapia eggs and larvae, study suggests
Columnaris disease, a potentially devastating condition affecting freshwater finfish, has been found infecting Nile tilapia eggs and larvae for the first time.
