Results of a new study by researchers at Nofima suggest that peracetic acid can safely be used as a water disinfectant in recirculating aquaculture systems (RAS) that contain salmon parr.

Perhaps one of the least aquatic forms of aquaculture involves the farming of crocodiles, alligators and caimans. These animals are referred to as semi-aquatic, and their husbandry is in some ways more similar to livestock production than to fish or shellfish …

As an aquaculture veterinarian based in Tasmania, Australia, Christine travels the continent to assist fish farms to improve biological productivity and solve fish health issues.

Anyone doubting the positive impact that academia can have on the development of the aquaculture industry should look at the example of Can Tho University in Vietnam – an institution that has been central to the meteoric rise of the country’s aquaculture secto…

My objective in this article is to challenge pathologists, immunologists and farmers by asking for a critical analysis on the application of a simple temperature manipulation, hyperthermia, to boost the innate immune system of fish.

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?
