“…was used as a singlecell protein as feed for the zebrafish Brachydanio rerio by Gajalakshmi and Raja. The results showed that the feed conversion ratio of fish fed with Streptomycetes single-cell protein was reduced by 3.74% compared to the control treatment [42]. In another study, Suguna and Rajendran investigated the effect of a diet containing freshwater Streptomyces strains on the feed conversion ratio and growth of the green swordtail (Xiphorous hellerii).…”

Discus fish (Symphysodon sp.) brings the largest export turnover to the ornamental fish industry in Vietnam. The intensive farming of discus fish to meet export market demand leads to a higher risk of bacterial disease, with Aeromonas being the main infectious agent. Continuous antibiotic use exerts selective pressure, fostering the emergence of antibiotic-resistant bacterial strains capable of causing diseases in fish. Streptomyces sp. considered as probiotics with the role of replacing antibiotics in applications such as promoting growth, improving survival rates, and controlling pathogenic bacteria in aquaculture. The primary objective of this study was to assess the influence of Streptomyces sp. on the growth performance, and Aeromonas density in intestine of discus fish and in culture water. Discus fish fed diets containing Streptomyces sp. TM1, TM7, and TM22 showed significantly higher growth parameters (45.24 - 58.72% of final body weight - FBW, 14.8 - 16.66% of final body length -FBL, 16.03 – 20.87 % of specific growth rate of weight – SGRW, 10.79 - 12.05 % of specific growth rate of length – SGRL, and 41.48 – 46.54 % of feed conversion ratio – FCR) compared to the control. Additionally, total Aeromonas densities of the fish treated with TM1, TM7, and TM22 showed a notable decrease compared to the control treatment in the rearing water with log CFU/ml values of 4.517 (Control), 2.554 (TM1), 2.571 (TM7), 2.222 (TM22) and in the intestines of fish with log CFU/g values of 5.597 (Control), 3.828 (TM1), 3.806 (TM7), 3.648 (TM22). Streptomyces sp. TM1, TM7, and TM22 could decreased total Aeromonas count in the gut of discus fish and in the rearing water, and boost the growth performance of discus fish (Symphysodon sp.).

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.
