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.
Read MoreAdvanced 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.
Read MorePrioritizing 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.
Read MoreGenetic 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.
Read MoreWhy 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.
Read MoreOptimizing 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.
Read MoreCould 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.
