Alltech highlights latest trout research at World Aquaculture 2015
"The gut microbiome of farmed trout is far more complex than previous research has documented," said Philip Lyons, at World Aquaculture 2015.
More than 2,000 attendees came together to see nearly 400 scientific posters and hear some of the 600 presentations included in the programme. Philip Lyons represented Alltech, the global leader in animal health and nutrition, with his talk, "Exploring the rainbow trout microbiome."
Lyons is completing his Ph.D. project at Bridge of Allan, Stirling, United Kingdom, aiming to characterise the gut microbiome of farmed salmonids (rainbow trout), and analyse the effect of diet on its composition. The project is employing next generation sequencing technology to enhance understanding of the importance of the gut microflora in the health of farmed fish.
He shared some of his key findings, including how the intestinal lumen and mucosal communities are different in terms of community structure. Next generation sequencing can detect shifts in rare microbial communities according to diet.
Lyons spoke about the impact of diet on the structure of the intestinal microbiome of farmed trout. In trials, trout fed All-G Rich™, microalgae from Alltech, had higher performance and condition factor as well as an increase in microbial diversity.
