An interview with Diego Robledo, PhD, scientist in aquaculture genetics and genomics at the Roslin Institute in Edinburgh.

Delousing salmon and gill health

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.

Antimicrobial resistance in Asia

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.

Diagnostic approaches for fish disease

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.”

Biosecurity can help tame tilapia lake virus

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 resistance in tilapia

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.

freshwater fish S. agalacitiae

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.
