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.
Understanding, but not application, of sustainable health measures in Vietnam’s pangasius industry
Pangasius farmers in Vietnam generally view vaccination in a positive light and are concerned about antibiotic use, although further work is required to ensure sustainable practices are widely implemented, new research led by University of Stirling suggests.
Lack of coordination threatens biosecurity in Spanish marine-fish farming
Spain’s marine aquaculture industry needs to make changes in order to meet biosecurity threats, according to a new EU-backed report.
Urgent action needed to address climate impact on aquaculture, study says
Urgent action is needed to understand and counter the effects of anthropogenic climate change on farmed fish, according to a new review of knowledge to date.
Diversity of sea bass pathogen strains highlights challenge in Mediterranean aquaculture
A new study analyzing three strains of the bacterium Vibrio harveyi found among farmed sea bass in the Mediterranean has underlined the diversity of the pathogen, which poses a severe threat to the region’s aquaculture.
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.
Submerged cages with air domes improve sea lice infestation but reduce welfare
Submerging Atlantic salmon sea cages with air domes can greatly reduce sea lice infestation levels, but this appears to come at a high cost.
Sea bass immunity to parasitic disease could lead to new treatments
No effective licensed therapies exist against amyloodiniosis, a disease of fish species caused by Amyloodinium ocellatum (AO) ectoparasites. However, new research has shown that European sea bass (ESB) can develop specific immunity to the disease, which could in turn lead to the development of vaccines.
RAS water exchange rates could affect Nile tilapia welfare
Recirculating aquaculture systems (RAS) are often viewed as viable options…
