Special Issue Information

Dear Colleagues,

Aquaculture, which continues to be the fastest-growing agri-food industry globally and employs millions along its supply chain, is not possible without regulating the health of aquatic animals. Aquatic animals' growth, behavior, digestion, immune systems, disease resistance, overall health, and output of aquaculture are all significantly influenced by their intestinal microbiomes. Therefore, normobiosis of the gut microbiota of farmed aquatic animals is crucial to sustain fast development in aquaculture. Using culture-dependent and -independent techniques, the gut microbiota of several aquatic animals have been isolated and classified at various taxonomic levels. Research indicates that numerous exogenous and/or native factors, such as development stage, diet, health state, trophic level, and habitat, have an impact on the gut microbiota profiles of aquatic species. To maintain fish health, improve aquaculture techniques, and create microbial-based medicines for cultured animals, it is crucial to understand the gut microbiota of aquatic species and their roles. Therefore, the aim of this Special Issue on “Exploration of the Gut Microbiota for Sustainable Aquaculture” is to collect research works that investigate how the gut microbiota are important for sustainable and green aquaculture.

Microalgae are promising as prebiotics in aquaculture. Arthrospira maxima has potential nutritional value but is poorly studied. We assessed A. maxima feed supplementation in tilapia fry and evaluated its effect on growth performance and gut microbiota. Fish were cultivated in ponds under 0%, 5%, 10%, and 15% A. maxima inclusion treatments. Growth parameters and biomass proximate analysis were assessed. A meta-amplicon analysis was performed on the gut microbiota using DADA2 and PICRUST2 for functional prediction. Among treatments, the 5% supplementation group seemed to present no negative effect on growth parameters and did not compromise the nutritional quality of tilapia fry biomass. Microbial composition was characterized by Cetobacterium, Pseudomonas and Aeromonas genera, and a predominance of beneficial metabolic pathways. Microbiota of tilapia fry fed with A. maxima showed unique genera with reported beneficial functions in tilapia. The abundance of potential pathogenic taxa was significantly decreased in supplementation treatments, possibly related to valuable compounds of A. maxima. The inclusion of the microalgae supported the stability of the microbiota, favoring the growth of commensal species. This seems to have an effect on decreasing the presence of pathogenic genera in the gastrointestinal tract. Overall, our work proposes 5% feed inclusion of A. maxima to be the most suitable for tilapia fry aquaculture to maintain production rates while improving general health. Full article
