Effects of microbe- and mussel-based diets on the gut microbiota in Arctic charr ( Salvelinus alpinus )

Dietary live yeast and increased water temperature influence the gut microbiota of rainbow trout

“…) and Arctic charr (Nyman et al . ). The absence of this bacterium in previous studies may be due to the fragility and fastidiousness of Mycoplasma , as it lacks cell walls and only grows when specific nutrients are available (Freundt and Razin ).…”

“…The high proportion of gut bacteria represented by the Tenericutes phylum or Mycoplasmatales order (Figs 4 and 5), specifically those identified as Mycoplasmaceae and Mycoplasma (Figs 6 and 7), have been found in similar proportions in previous studies on rainbow trout (Lowrey et al 2015;Lyons et al 2017bLyons et al , 2017c and Atlantic salmon (Green et al 2013;Zarkasi et al 2014) using high-throughput sequencing. In contrast, many studies have not identified Mycoplasmatales or Mycoplasma in the gut of rainbow trout (Wong et al 2013;Ingerslev et al 2014;Lyons et al 2017a;Huyben et al 2017a;Michl et al 2017), Atlantic salmon (Gajardo et al 2016;Schmidt et al 2016;Dehler et al 2017) and Arctic charr (Nyman et al 2017). The absence of this bacterium in previous studies may be due to the fragility and fastidiousness of Mycoplasma, as it lacks cell walls and only grows when specific nutrients are available (Freundt and Razin 1958).…”

Intestinal microbiota lipid metabolism varies across rainbow trout (Oncorhynchus mykiss ) phylogeographic divide

“…; Nyman et al . ). Firmicutes were the most abundant group found in our experiment which has also been observed in many other salmonid studies (Mansfield et al .…”

Dietary effect of low fish meal aquafeed on gut microbiota in olive flounder (Paralichthys olivaceus) at different growth stages

“…The advent of next-generation sequencing (NGS) enabled more sophisticated analysis of complex gut microbiota by a culture-independent approach with unprecedented resolution and throughput (Jovel et al, 2016). The NGS technique has been used to explore the dietary effects on gut microbiota of different fish species, including rainbow trout (Oncorhynchus mykiss; Desai et al, 2012), sea bream (Sparus aurata;Estruch et al, 2015), Arctic charr (Salvelinus alpinus; Nyman, Huyben, Lundh, & Dicksved, 2017), field eel (Monopterus albus; Peng et al, 2019), yellowtail kingfish (Serio lalalandi; Soriano et al, 2018), and channel catfish (Ictalurus punctatus; Wang et al, 2019). Most of these studies investigated the dietary effects on fish gut microbiota for a short-term administration, but the long-term dietary effects at different growth stages have generally been overlooked.…”
