Monitoring fish using sound is on the rise in aquaculture, meeting a need to accurately assess the health and welfare of farmed-fish populations in changing environments.
The Norwegian Veterinary Institute’s latest Fish Health Report1 has highlighted record numbers of sea lice treatments and bacterial diseases causing complications for fish producers in Norway — but in order for its authors to keep up with changes in the industry, new, more specific data needs to be collected and made available in coming years.
A Europe-wide project is helping establish new approaches to tackle economically important parasites and pathogens, both in the Mediterranean and Norway.
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.

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.
