Reducing the need for live fish in vaccine research and development
Initiatives to avoid the use of live animals in research are happening across academia and industry worldwide, based on the “3 Rs” principles — replacement, reduction and refinement.
Read MoreResearch highlights ways to improve the lives of cleaner-fish species
The welfare of lumpfish used in biological control of sea lice significantly worsens after they are moved to cages at sea, while for wrasse, challenges in nurseries are causing problems before sea transfer.

Lower stocking densities could reduce the frequency of skeletal deformities in young gilthead sea bream, increasing fish welfare and productivity.
Read MoreNew tools can transform understanding of aquaculture’s microbiology
The microbiome of aquaculture systems has long been known to have a significant role in fish health and welfare issues, yet a full understanding of these interactions has often eluded experts.
Read MoreHow 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.
Read MoreUser-friendly tools put cleaner fish welfare in the spotlight
A package of tools designed by scientists at Swansea University has been made available to help producers monitor the welfare of lumpfish, commonly used as biological control for sea lice on salmon farms.
Read MoreTaking farmed fish welfare beyond the ‘five freedoms’
Over the last decade, a considerable body of research has demonstrated the capacity of fish to suffer – yet there remain unknowns around what causes the most serious negative impacts on their quality of life.
Read MoreSubmerged cages with air domes improve sea lice infestation but reduce welfare
Submerging Atlantic salmon sea cages with air domes can greatly reduce sea lice infestation levels, but this appears to come at a high cost.
Read MoreRAS water exchange rates could affect Nile tilapia welfare
Recirculating aquaculture systems (RAS) are often viewed as viable options for culture of certain fish species in the face of growing environmental regulations for sustainable aquaculture practices. New work from researchers at the Kwame Nkrumah University of Science & Technology in Ghana suggests that moderately high levels of water exchange in RAS provide the best…
