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.
Biosecurity’s crucial role in ensuring sustainable future for global aquaculture
An interview with Vera Agostini, deputy director, Fisheries and Aquaculture Division, the Food and Agriculture Organization (FAO) of the United Nations.
The road to sea-lice-resistant Atlantic salmon
An interview with Diego Robledo, PhD, scientist in aquaculture genetics and genomics at the Roslin Institute in Edinburgh.
Non-medicinal delousing approaches cause damage to salmon gill tissue
New research shows that thermal and mechanical delousing techniques used in Atlantic salmon aquaculture can cause damage to gill tissue, though the health impacts of this on farmed fish remain unknown.
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.
Managing high-tech vaccination on Canada’s salmon farms
Demand for vaccination is ever-growing in the Canadian salmon industry, and the country’s producers have made a big shift toward mechanized approaches in getting the job done.
Advanced diagnostic approaches for fish disease are welcome, but sometimes simpler is better
With technologies for molecular diagnosis of fish disease increasingly available, sometimes simpler approaches that have great diagnostic power are being ignored.
Prioritizing biosecurity can help tame tilapia lake virus
Tilapia lake virus (TiLV) is an emerging threat to tilapia aquaculture, with mortalities in some cases up to 90%. But with a focus on biosecurity, the impact can be considerably lessened.
