Salmonids
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.
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.
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.”
Genetic technologies helping breed disease-resistance traits in tilapia
Tilapia farming is catching up to the salmon industry in its application of selective breeding to improve resistance against key pathogens, according to a leading geneticist.
Seeking a better understanding of complex gill disease in salmon
Researchers from Canada’s University of Prince Edward Island have received a CAD $4.7 million grant to develop an early warning system for complex gill disease on salmon farms, based on cutting-edge genetic sequencing techniques.
Scottish Sea Farms: How to reach zero antibiotics in commercial salmon farming
Aquaculture has generally seen more success in antibiotic reduction than other livestock sectors. Scottish Sea Farms have gone further, reaching zero antibiotics in 2020. How did they manage it?
Making sure salmon smolt raised in RAS are equipped for sea transfer
Recirculating aquaculture systems (RAS) are on the rise worldwide, and one of their most common applications is in rearing Atlantic salmon smolts before transfer to sea.
