Progress in fish gastrointestinal microbiota research

Reviews in Aquaculture, Journal Year: 2017, Volume and Issue: 10(3), P. 626 - 640

Published: Feb. 2, 2017

Abstract The gastrointestinal (GI) microbiota of vertebrates plays critical roles in nutrition, development, immunity and resistance against invasive pathogens. In the past decade, research GI mammals has drastically increased our knowledge on their relationship with health disease. However, understanding fish intestinal is limited. This review provides an overview gut microbiota, including microbial composition, formation, factors that affect microbes characteristics compared human mice. Further, updated gnotobiotic zebrafish elaborated insights gained functions are discussed. Understanding will guide development probiotics, prebiotics hopefully probiotic effectors as novel additives to improve fish.

Gut Microbiota and Energy Homeostasis in Fish

Frontiers in Endocrinology, Journal Year: 2019, Volume and Issue: 10

Published: Jan. 23, 2019

The microorganisms within the intestinal tract (termed microbiota) have been shown to interact with gut-brain axis, a bidirectional communication system between gut and brain mediated by hormonal, immune neural signals. Through these interactions, microbiota might affect behaviors, including feeding behavior, digestive/absorptive processes (e.g. modulating motility barrier), metabolism, as well response, repercussions on energy homeostasis health of host. To date, research in this field has mostly focused mammals. Studies non-mammalian models such fish may provide novel insights into specific mechanisms involved microbiota-brain-gut axis. This review describes our current knowledge possible effects feeding, digestive processes, growth fish, emphasis influence hormones, environmental factors inter-specific differences.

Exploring fish microbial communities to mitigate emerging diseases in aquaculture

FEMS Microbiology Ecology, Journal Year: 2017, Volume and Issue: 94(1)

Published: Nov. 28, 2017

Aquaculture is the fastest growing animal food sector worldwide and expected to further increase feed human population. However, existing (re-)emerging diseases are hampering fish shellfish cultivation yield. For many diseases, vaccination protocols not in place excessive use of antibiotics other chemicals substantial concern. A more sustainable disease control strategy protect from could be achieved by introduction or augmentation beneficial microbes. To establish maintain a 'healthy' microbiome, fundamental understanding diversity temporal-spatial dynamics fish-associated microbial communities their impact on growth health aquatic hosts required. This review describes insights functions bacterial elucidated with next-generation sequencing discusses potential microbes mitigate aquaculture.

Abstract The mucosal surfaces of fish represent an important barrier that supports and regulates a diverse array microbial assemblages contributes to the overall health fitness host. For farmed species, knowledge how these host–microbial systems adapt respond various stressors is pivotal for managing health, nutrition optimizing productivity in aquaculture. While our understanding communities factors shape them now suggest balanced microbiota critical healthy functioning fish, mechanisms behind interactions are still poorly understood. Much existing research has focused on characterizing taxonomic diversity different across body (e.g. skin, gills gastrointestinal tract), response changing nutrition, environmental conditions. However, specific functional contributions (or members) remain elusive, especially or diseased fish. Here, we review current their interplay likely involvement with We also seek address identify gaps explore future prospects improving

Abstract The rearing of fish in intensive systems reduces their immunity leading to eruption diseases, consequently prompting the use antibiotics. Antibiotics are currently used cultured globally treat/prevent diseases. On one hand, antibiotics aquaculture help improve health by killing or inhibiting pathogenic bacteria proliferation. However, on other they cause multiple side effects. To date, information systemic effects is scattered and potential human risk remains elusive.
