Better net-cleaning tech needed to contain harmful particles on fish farms — study
Cleaning the nets of pens on fish farms at sea releases millions of harmful biofouling particles that not only spread between pens but into other farms up to 5 kilometers away too, a study in Norway has revealed. But despite the concerning results, help is at hand for producers.

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.
Read MoreResearch 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.
Read MoreNorwegian 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.
Read MoreUnderstanding 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.
Read MoreManaging 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.
Read MoreSimulation offers insight into emerging-disease spread on salmonid farms
![Salmonid x[]](https://fishfarmforum.com/wp-content/uploads/2023/08/Salmonid-675x42038-1.jpg)
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.
Read MoreVaccine study offers new insight on Norway’s winter ulcer problem
In recent years, the Norwegian aquaculture industry has struggled against the rise of “variant” forms of Moritella viscosa, a bacterium which causes the disease winter ulcer in Atlantic salmon. This has led to concerns about the efficacy of existing vaccines against the pathogen.
