A new study on aquaculture microbiota!2025-01-09
Resisting heat stress!
In the warm summer of 2022, water temperatures soared to a historic 30.49ºC on the Spain’s Mediterranean coast, testing the limits of the farmed gilthead sea bream (Sparus aurata). The result? A dramatic shift in gut microbiota, with a powerful increase in Brevinema, a genus now under the spotlight as a potential heat-stress marker. This is the main result of our latest publication, performed in the framework of the AQUAEXCEL3.0 European project, and the GVA-ThinkInAzul Next Generation EU project, in collaboration with the NUKAMEL NV company.
We observed that the increase of Brevinema in response to heat stress was due to a breakdown in intestinal homeostasis rather that changes in the microbial community in the surrounding water. Moreover, dietary interventions with emulsifiers and low-fat diets partially reversed this microbial imbalance, also restoring the circulating levels of cortisol and glucose.
Using Brevinema as a thermal stress marker, we can contribute to promote effective feeding strategies for mitigating the effects of global warming on aquaculture, ensuring the sector resilience.
