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.
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.
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?
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.
Among the most economically important farmed fish, production methods, levels of technological development and the types of fish health and well-being issues faced can vary widely — and those in the industry that make a move between species face a learning curve.
While there are efficacious commercial vaccines available against a number of important diseases that affect Atlantic salmon, there are still pathogens for which there are currently no such options available.
A novel gill-tissue diagnostic technology — supported by rapid laboratory analysis — has enabled salmon-farming giant Mowi to much more precisely gauge when to transfer its smolts to sea cages within its Pacific West Coast operations.
