Low-light conditions affect tilapia survival and disease resistance

Light can affect the survival, growth and immune response of fish. New research shows that persistent exposure to low-intensity light decreases the survival rate of Nile tilapia but stimulates their disease resistance.

Tilapia

Tilapia strain resistant to damaging virus could help reduce losses

The discovery of a strain of Nile tilapia resistant to tilapia lake virus (TiLV) may prove useful in the fight to reduce the impact of the pathogen, which has emerged in the last decade and can cause extremely high mortalities among farmed fish.

Bacterial threats to Asian tilapia aquaculture

New knowledge sheds light on bacterial threats to Asian tilapia aquaculture

A growing understanding of bacterial pathogens is highlighting the challenge Asian tilapia producers face, but good health-management practices on fish farms and new diagnostic technologies can help, says an academic expert.

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.

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.
