Visual observation is inadequate to assess whether anesthetics have rendered fish unconscious, leading to potential welfare risks, according to research in Sweden.
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.
Sea lice, gill health and environmental challenges are the major considerations for Scottish salmon producers looking to improve the welfare of their fish, according to an Institute of Aquaculture survey.

Lower stocking densities could reduce the frequency of skeletal deformities in young gilthead sea bream, increasing fish welfare and productivity.
Gene editing could aid fish resistance to disease, as well as provide other advantages to producers, but there are still barriers to overcome before it becomes widely used in global aquaculture, according to an industry expert.
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.
