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.

Submerged cages with air domes improve sea lice infestation but reduce welfare
Submerging Atlantic salmon sea cages with air domes can greatly reduce sea lice infestation levels, but this appears to come at a high cost.
Sea bass immunity to parasitic disease could lead to new treatments
No effective licensed therapies exist against amyloodiniosis, a disease of fish species caused by Amyloodinium ocellatum (AO) ectoparasites. However, new research has shown that European sea bass (ESB) can develop specific immunity to the disease, which could in turn lead to the development of vaccines.
RAS water exchange rates could affect Nile tilapia welfare
Recirculating aquaculture systems (RAS) are often viewed as viable options…
Levels of antimicrobial resistance in Asian aquaculture ‘concerning,’ say scientists
Twenty years’ worth of data “raise urgent concerns” about antimicrobial resistance in Asian aquaculture, say the authors of a new review.
New research on deltamethrin resistance could pave way for optimized sea lice treatment
New research on deltamethrin resistance in sea lice could help improve the effectiveness and reduce the costs of treating the global salmon industry’s “billion-dollar problem.”
Just add stones? Simple alterations to aquaculture environment can aid disease fight
Simple environmental enrichments in aquaculture can reduce the impact of pathogens on salmonids, a new study from Finland found.
Eastern Mediterranean sea bass more resistant to highly pathogenic virus strain
Eastern Mediterranean populations of sea bass showed three times the survival rate of Atlantic Ocean and Western Mediterranean stocks against a pathogenic strain of nervous necrosis virus (NNV) in a new challenge study.
Vaccine progress critical to sustainable freshwater aquaculture in Southeast Asia
A lack of vaccines and susceptibility to bacterial pathogens is putting Southeast Asia’s booming freshwater farming industry at risk, according to scientists.
