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.
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.
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.”
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.
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.
Why common bacterium from freshwater fish poses a health threat — and what can be done
Some subtypes of the bacterium Streptococcus agalacitiae, which is commonly found in fish and humans but can turn virulent, are proving a bigger threat to health than others.
Optimizing recirculating aquaculture systems: Fish farming’s hot topic
It’s a boom time for recirculating aquaculture systems (RAS) — but unanswered questions remain in ensuring this ever-more-prevalent approach to large-scale fish production reaches its considerable potential.
Could farming seaweed hold the key to curbing cattle methane emissions?
Aquaculture can spin off new sustainability ideas, but few are more ambitious than Greener Grazing — an effort to commercialize a seaweed that could cut methane production from grazing animals.
Safety and welfare concerns drive shift to licensed anesthetic in Mediterranean aquaculture
Improving standards on Mediterranean fish farms is driving interest in Tricaine PHARMAQ — the only authorized fish anesthetic product.
Vaccines boost Greece’s seabass and seabream aquaculture — but challenges remain
Aquaculture in Greece has endured some ups and downs since its establishment in the 1980s, from the Greek financial crisis to the Covid-19 pandemic.
