Abstract
dc.description.abstract
Arapaima gigas is a large air-breathing fish found in Amazonian rivers, a characteristic that
gives this species an advantage in oxygen-deprived waters. It shows high potential for aquaculture
in the Amazon region due to its fast growth rate that approaches 10–15 kg/year. The aim of this
study was to explore the composition of the intestinal bacterial community of Arapaima gigas reared
in Ecuador using 16S rRNA gene high-throughput sequencing. The analysis revealed significant
differences in alpha diversity indices (p < 0.05) and differential distribution of minor components of
the intestinal microbiome between small and large fish. However, components with greater relative
abundance, such as Cetobacterium, are found in similar proportions.
