“…Studies have shown that the genus Streptomyces increased growth, survival and resistance to disease in the giant tiger prawn Penaeus monodon 60 and Litopenaus vannamei 135 . In another study, different strains of Streptomyces were found to have significantly increased the weight and SOD activity of the two juvenile oysters of commercial and aquaculture interest 50 . The enhancement of selected immune parameters in L. vannamei and grass carp using Arthrobacter bussei and Streptomyces termitum N‐15, respectively, have been reported recently 56,70 …”

Aquaculture is one of the most important economic activities in the world. However, the intensification of culture practices resulted in the emergence of various diseases caused by microorganisms and non-infectious diseases caused mainly by the deterioration of water quality. Several prophylactic and treatment options have been exploited over the years to tackle the disease problem in aquaculture. Previously, antibiotics have been used indiscriminately for treating many fish diseases which resulted in the emergence of antimicrobial resistance. To overcome the failure of existing management strategies, innovative antimicrobial drug research is crucial and actinomycetes have proven to be trustworthy sources of new antimicrobial chemicals and are one of the most economically and biotechnologically important bacteria with multitude of functions. This review updates and highlights the role of actinomycetes in encouraging sustainable aquaculture practices and identifies opportunities for additional research and development. Many genera of actinomycetes were found to enhance the growth and survival of cultured species by producing many nutritional factors. They also improve the water quality of culture systems by the production of hydrolytic enzymes. Actinomycetes were found to improve the immunity of aquatic organisms by augmenting many immune parameters and making them more resistant to infection. Many actinomycetes have been discovered to produce antagonistic substances and exhibited antibacterial, antiviral, antibiofilm and anti-quorum sensing activities. Probiotic potential of many actinomycetes has been widely explored. Even though actinomycetes have been widely used in aquaculture for multi purposes, the exact mechanism of action of these bacterial groups is poorly understood and novel biotechnological tools can be used for unravelling this.

The Pacific oyster Crassostrea gigas lives in microbe-rich marine coastal systems subjected to rapid environmental changes. It harbours a diversified and fluctuating microbiota that cohabits with immune cells expressing a diversified immune gene repertoire. In the early stages of oyster development, just after fertilization, the microbiota plays a key role in educating the immune system. Exposure to a rich microbial environment at the larval stage leads to an increase in immune competence throughout the life of the oyster, conferring a better protection against pathogenic infections at later juvenile/adult stages. This beneficial effect, which is intergenerational, is associated with epigenetic remodelling. At juvenile stages, the educated immune system participates in the control of the homeostasis. In particular, the microbiota is fine-tuned by oyster antimicrobial peptides acting through specific and synergistic effects. However, this balance is fragile, as illustrated by the Pacific Oyster Mortality Syndrome, a disease causing mass mortalities in oysters worldwide. In this disease, the weakening of oyster immune defences by OsHV-1 µVar virus induces a dysbiosis leading to fatal sepsis. This review illustrates the continuous interaction between the highly diversified oyster immune system and its dynamic microbiota throughout its life, and the importance of this cross-talk for oyster health. This article is part of the theme issue ‘Sculpting the microbiome: how host factors determine and respond to microbial colonization’.
