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.
