Columnaris disease affects Nile tilapia eggs and larvae, study suggests
Columnaris disease, a potentially devastating condition affecting freshwater finfish, has been found infecting Nile tilapia eggs and larvae for the first time.
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 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.
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.
RAS water exchange rates could affect Nile tilapia welfare
Recirculating aquaculture systems (RAS) are often viewed as viable options…
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.
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.
