Why fish vaccines are increasingly coming in smaller doses
An interview with Dr Bjørn Brudeseth, PhD, PHARMAQ
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.
Cleaner-fish health risks highlighted as use in aquaculture rises
Cleaner fish have proved an effective alternative method of sea louse control — but their widespread introduction brings with it a new threat of pathogens and parasites, and available treatments are falling short of requirements.
