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.

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.

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.

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.

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.

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.

Submerging Atlantic salmon sea cages with air domes can greatly reduce sea lice infestation levels, but this appears to come at a high cost.

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…
