Scientists closing in on ways to boost immune mechanisms of mollusks
Farmed mollusks are threatened with a number of diseases, but given that — unlike vertebrates — animals like mussels and clams don’t have antibodies or T or B cells to fight infection, coming up with health interventions has often proved elusive.

Mollusk farms must prepare for more disease under climate change
Warmer seawater is creating perfect conditions for many mollusk pathogens to thrive, scientists have warned.
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.
Yeast could aid shift away from fish-based diets in rainbow trout aquaculture
Torula yeast could be a promising option for inclusion in non-fishmeal feeds, with scientists finding links to production and immune improvements in a study using rainbow trout.
Advanced genomics data could spark breeding revolution in European aquaculture
New genomics data on six commercially important fish species in Europe could have major implications for breeding programs, but there is work still to be done to realize the benefits.
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.
Reanalysis shows true identity of bacteria involved in lactococcosis cases
The bacterium Lactococcus petauri has played a more significant role in historical cases of the disease lactococcosis than was previously thought, new research suggests.
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.
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.
