- Gut Microbiota Response in Meagre () Subjected to a Plant-Based Nutritional Challenge. Oliveira, Joana Barata, Marisa Santos, Rafaela Serra, Cláudia Soares, Florbela Pousão-Ferreira, Pedro Oliva-Teles, Aires Couto, Ana The gut plays a central role in fish nutrition, immunity, and overall health, making it key in aquaculture research. The microbiota, crucial to gut function, is increasingly studied as an indicator of health and nutritional status. This study characterized the gut microbiota of juvenile meagre () (initial weight 4.6 ± 0.4 g) fed for seven weeks on diets in which fishmeal (FM) and fish oil (FO) were replaced by increased proportions of plant-based ingredients, with the aim of identifying microbial profiles associated with nutritional challenge. Fish were fed a FM/FO control diet (CTRL; 55.1% FM, 11.3% FO), a low FM/FO diet (CD; 15% FM, 7% FO), or a very low FM/FO diet (ED; 5% FM, 5% FO). Next-generation sequencing analysis of gut mucosa and digesta revealed no significant differences in alpha or beta diversity among different dietary groups. dominated all samples, particularly , , , and . Significant differences were only observed in low-abundance taxa (
