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.
Read MoreNew system to assess gill disease could help salmon producers
Gill disease in Atlantic salmon is caused by a number of pathogens and has different clinical and pathological signs. This means that to date, there has been no standardized methodology developed for field diagnosis, despite the fact that gill health issues are a growing concern for salmon producers in all the major salmon-producing nations.
Read MoreTaking farmed fish welfare beyond the ‘five freedoms’
Over the last decade, a considerable body of research has demonstrated the capacity of fish to suffer – yet there remain unknowns around what causes the most serious negative impacts on their quality of life.
Read MoreTilapia 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.

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 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.
