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 …
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.
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.
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.
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?
As the aquaculture industry expands, it needs every feed option – both conventional and alternative – at its disposal. But what steps can the sector take to bring sustainable feed ingredients online?
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.
Devices that produce nanobubbles are becoming increasingly popular in a range of aquaculture operations, with a growing number of studies supporting their value – both in improving production and in reducing the environmental impact of the industry.
