How to reduce antibiotic use in Chile, the Americas’ salmon-production giant

Cutting antibiotic use is one of the major sustainability priorities in global food production, and while aquaculture has taken steps along this road, there’s still a long way to go.

Ensuring elite disease management during challenging time for Canada’s salmon farms

Salmon farming in Canada is facing some unprecedented challenges, but there is no sign of the industry letting its guard down when it comes to disease prevention.

One pathogen strain seems the main culprit in damaging salmonid disease

A distinct strain of the main fungus-like pathogen which causes saprolegniosis — thought to be responsible for around 10% of economic losses in the salmonid industry — looks likely to be responsible for the majority of outbreaks of the disease on Atlantic salmon fish farms.

Research highlights risks of thermal delousing treatments for unhealthy salmon

Thermal sea lice treatments do not appear to cause increases in pathogens which threaten farmed salmon, but the risk of stress-related mortalities means that fish already suffering from disease should not undergo thermal sea lice treatments, according to Institute of Aquaculture researchers.

How acoustic technologies are aiding fish health and welfare

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.

Norwegian salmon industry’s annual ‘health check’ underlines areas for improvement

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.

Understanding plankton threats to salmon requires a mix of old and new technologies

Using both “traditional” microscopy and environmental DNA (eDNA) analysis can help paint a complete picture of plankton threats to salmon aquaculture, according to University of Glasgow research.

Managing health risks in Mediterranean aquaculture’s least-controllable environment

The consolidation of Mediterranean aquaculture is standardizing production practices in the region and leading to better biosecurity management, but growing out fish in the unforgiving environment at sea poses the sort of challenge that demands realistic, practical solutions.

Simulation offers insight into emerging-disease spread on salmonid farms

A new computer simulation approach may help better understand how emerging diseases could spread across salmonid farms in England and Wales and the best measures to limit their impact.
