Biological and Ecological Roles of External Fish Mucus: A Review

Fishes, Journal Year: 2018, Volume and Issue: 3(4), P. 41 - 41

Published: Oct. 9, 2018

Fish mucus layers are the main surface of exchange between fish and environment, they possess important biological ecological functions. research is increasing rapidly, along with development high-throughput techniques, which allow simultaneous study numerous genes molecules, enabling a deeper understanding composition its plays major role against infections, has mostly focused on bioactive molecules (e.g., antimicrobial peptides immune-related molecules) associated microbiota due to their potential in aquaculture human medicine. However, external surfaces also play roles social relationships conspecifics (fish shoaling, spawning synchronisation, suitable habitat finding, or alarm signals) interspecific interactions such as prey-predator relationships, parasite–host interactions, symbiosis. This article reviews (gills skin) mucus, discussing importance protection pathogens intra interactions. We discuss advances that “omics” sciences bringing into studying

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.

The Inner Workings of the Outer Surface: Skin and Gill Microbiota as Indicators of Changing Gut Health in Yellowtail Kingfish

Frontiers in Microbiology, Journal Year: 2018, Volume and Issue: 8

Published: Jan. 15, 2018

The mucosal surfaces and associated microbiota of fish are an important primary barrier provide the first line defense against potential pathogens. An understanding skin gill microbial assemblages factors which drive their composition may useful insights into broad dynamics host-microbial relationships, reveal underlying changes in health status. This is particularly pertinent to cultivated systems whereby various stressors led conditions (like enteritis) impinge on productivity. As economically species, we assessed whether outer-surface bacterial communities reflect a change gut status Yellowtail Kingfish (Seriola lalandi). Active were surveyed from RNA extracts swabs gills by constructing Illumina 16S rRNA gene amplicon libraries. Proteobacteria Bacteroidetes predominant both gills, with enrichment key β-proteobacteria (Nitrosomonadales Ferrovales). Fish exhibiting early stage chronic lymphocytic enteritis comprised markedly different global compared those deemed healthy late stages disease. corresponded overall loss diversity Actinobacteria, gills. In contrast, generally similar individuals, though some distinct taxa. conclusion, factor defines likely reflects immune states during onset like enteritis. study represents investigate outer response enteritis, revealing biomarkers for assessing commercial aquaculture systems.

Skin microbiome of coral reef fish is highly variable and driven by host phylogeny and diet

Microbiome, Journal Year: 2018, Volume and Issue: 6(1)

Published: Aug. 24, 2018

The surface of marine animals is covered by abundant and diversified microbial communities, which have major roles for the health their host. While such microbiomes been deeply examined in invertebrates as corals sponges, living on vertebrates received less attention. Specifically, diversity these microbiomes, variability among species, drivers are still mostly unknown, especially fish species coral reefs that contribute to key ecosystem services while they increasingly affected human activities. Here, we investigated knowledge gaps analyzing skin microbiome 138 individuals belonging 44 reef same area. Prokaryotic communities fishes highly diverse, with average more than 600 OTUs per fish, differ from planktonic microbes. Skin varied between individual interspecific differences were slightly coupled phylogenetic affiliation host its ecological traits. These results highlight biodiversity greater previously appreciated, since high macro-organisms supports a community. This suggest beyond loss reefs-associated macroscopic anthropic activities could also lead unexplored host-associated diversity, urgently needs be assessed.

Fish skin mucus serves as a first line of defense against pathogens and external stressors. In this study the proteomic profile lumpsucker was characterized using 2D gels coupled with tandem mass spectrometry. Mucosal proteins were identified by homology searches across databases SwissProt, NCBInr vertebrate EST. The clustered into ten groups based on their gene ontology biological process in PANTHER (www.patherdb.org). Calmodulin, cystatin-B, histone H2B, peroxiredoxin1, apolipoprotein A1, natterin-2, 14-3-3 protein, alfa enolase, pentraxin, warm temperature acclimation 65 kDa (WAP65kDa) heat shock identified. Several are known to be involved immune and/or stress responses. Proteomic established could benchmark for differential proteomics studies.
