There is growing evidence that microplastic pollution in seawater could serve as reservoirs for pathogens in aquaculture, according to a University of Exeter review of current evidence in this emerging field.
Taming tilapia lake virus requires improved expert collaboration
Tilapia lake virus (TiLV) is an emerging threat to aquaculture, having been discovered in 2014 and now reported in 16 countries.
China making up for lost time in aquatic vaccine development
China is now responsible for over 70% of global farmed-fish production. Finding appropriate responses to fish disease has not been as rapid, researchers from Huazhong Agricultural University acknowledged — but new options in development suggest that the nation is fast catching up.
Why prophylactic use of antibiotics poses a problem for aquaculture
