“…Bacteria belonging to the genus Ochrobactrum have previously been documented in fish (Nayak, 2010) and in the human gastric niche (Kulkarni et al, 2017), but until the present, O. thiophenivorans had been detected only in the hindgut of the forest cockchafer (Alonso-Pernás et al, 2017). Likewise, Bradyrhizobium and Rhizobium-related species have been found in the gut microbiota of sea bass (Carda-Dieguez et al, 2014; Gatesoupe et al, 2016) and Nile tilapia (Xia et al, 2018). Such bacterial groups are interesting because of their relative abundance in DI samples and because they are associated with the production of a variety of enzymes with cellulolytic and pectolytic activities.…”

The gut microbiota plays a key role in animal health, including immune and metabolic homeostasis. Despite the economic relevance of the sturgeon, studies addressing the gut microbiome of this species are scarce and have focused only on the hindgut. The objective of this work was to use Illumina metabarcoding technology to compare the bacterial microbiomes of two different intestinal locations, the proximal intestine (small intestine) and the distal intestine (hindgut containing the spiral valve), of healthy Siberian sturgeons (Acipenser baerii) reared on two different farms in Spain. Although a high degree of interindividual variability was observed, certain differences between the anatomical parts and between the geographical locations were clear. The results show that the sequences corresponding to the most abundant taxa were the basis for clustering according to anatomical region (proximal and distal intestine), whereas the less abundant taxa were the basis for clustering according to the geographical location of the fish farms. Finally, the results also indicate the existence of certain bacteria that are present in the intestinal tracts of all the fish analyzed in this study; this information may be useful in future studies aiming to establish differences based upon fish health or disease.

“…In FishBase (Froese & Pauly, 2022 ), there are 108 scientific names, but only 65 are valid species. Currently, new Rhinogobius species are being identified (Takahashi & Okazaki, 2017 ; Xia et al, 2018 ), and these new species descriptions may suggest the list is not yet complete.…”

Rhinogobius candidianus is a freshwater goby distributed in north, northwest, west, and south Taiwan, but this species has been introduced to east Taiwan and became dominant. To investigate its native population genetic diversity and structure and evaluate the sources and diversity of translocated populations, the mitochondrial DNA control region and cytochrome b gene (1981 bp) from 220 specimens were analyzed. These results indicated that (1) the east populations originated from two sources in west Taiwan; (2) translocated populations exist in east Taiwan and south Taiwan; (3) many populations have likely been moved secondarily by human intervention; (4) the effective size of the populations had declined greatly; (5) within the native populations, the ancestral populations colonized Taiwan during the land bridge phase in the Pleistocene through north Taiwan; (6) the landform changes in Taiwan shaped the population structure; and (7) the landforms of the coastline during glaciation also shaped the native range. The low‐level genetic diversity, high population differentiation, and population decline greatly suggest the need for resource management and conservation interventions. Four clades ( α – δ ) should be managed as four distinct evolutionarily significant units, while the translocated populations should be managed as separate management units. Moreover, the translocated populations in east Taiwan should be evaluated and monitored carefully.
