New research suggests that balancing levels of phytoplankton in shrimp ponds can prevent the growth of Vibrios, including Vibrio parahaemolyticus – the causative agent of EMS/AHPND.
Researchers in China caution that some commercial probiotics for the aquaculture industry may be mislabelled, and also contain cytotoxins and antibiotic resistance genes that can be passed to other organisms.
Adding microalgae T pseudonana (Thalassiosira pseudonana) to culture water can improve overall water quality, suppress vibrio levels and boost growth rates for intensively farmed whiteleg shrimp.
Some salmon producers may keep their cages fully submerged to keep sea lice at bay, but results from a recent trial suggest that while this reduces lice infestations, it is detrimental to salmon welfare and production goals.
A recent feed trial has found that supplementing Nile tilapia diets with bakers’ yeast (Saccharomyces cerevisiae) can change the fishes’ intestinal morphology, leading to improved nutrient uptake, immune responses and growth performance.
In collaboration with local villagers and scientists, an international team of researchers are breeding and releasing freshwater prawns into the Senegal River in an attempt to combat a spiralling outbreak of schistosomiasis – a disease that has infected millio…
Despite being susceptible to multiple viral and bacterial diseases, less than 5 percent of farmed tilapia are vaccinated. How can stakeholders work together to improve the industry’s vaccine uptake?

Organised by The Fish Site and Calysta, the event has been inspired by trials …
Shrimp fed diets containing FeedKind, a novel microbial protein produced by Calysta, have been shown to be more resistant to Vibrio parahaemolyticus – the source of early mortality syndrome (EMS).
Catfishes have surpassed tilapia in global aquaculture production and – helped in part by the sheer number of their species and their extensive geographical range – they are set to remain at the top table.
As shrimp producers across the globe face more extreme weather events due to climate change, the Alune* farming experts give their advice on how farmers can prepare for the rainy season and keep their ponds healthy.
