“…Although Clostridium was not observed in high proportions, other genera from the order Clostridiales contributed considerably to the milkfish gut microbiome with possibly similar biological functions, specifically Epulopiscium and Romboutsia . These taxa have been identified as prominent members of the gut microbiome in herbivorous and detritivorous fish exhibiting a symbiotic relationship with their host [ 70 , 71 ].…”

Milkfish, an important aquaculture species in Asian countries, are traditionally cultured in outdoor-based systems. There, they experience potentially stressful fluctuations in environmental conditions, such as temperature, eliciting changes in fish physiology. While the importance of the gut microbiome for the welfare and performance of fish has been recognized, little is known about the effects of thermal stress on the gut microbiome of milkfish and its interactions with the host’s metabolism. We investigated the gut microbiome of juvenile milkfish in a thermal stress experiment, comparing control (26 °C) and elevated temperature (33 °C) treatments over three weeks, analyzing physiological biomarkers, gut microbiome composition, and tank water microbial communities using 16S amplicon sequencing. The gut microbiome was distinct from the tank water and dominated by Cetobacterium, Enterovibrio, and Vibrio. We observed a parallel succession in both temperature treatments, with microbial communities at 33 °C differing more strongly from the control after the initial temperature increase and becoming more similar towards the end of the experiment. As proxy for the fish’s energy status, HSI (hepatosomatic index) was correlated with gut microbiome composition. Our study showed that thermal stress induced changes in the milkfish gut microbiome, which may contribute to the host’s habituation to elevated temperatures over time.

“…Bifidobacterium are commonly reported in the GI tract of endothermic animals, but they are only been isolated in few studies from the digestive tract of finfish (Merrifield et al, 2014 ). Recently, Boonanuntanasarn et al ( 2017 ) revealed increased population level of Bifidobacterium spp. by feeding Nile tilapia ( Oreochromis niloticus ) fingerlings fed inulin and Jerusalem artichoke ( Helianthus tuberosus ).…”

Lactic Acid Bacteria in Finfish—An Update

A complex and dynamic community of microorganisms, play important roles within the fish gastrointestinal (GI) tract. Of the bacteria colonizing the GI tract, are lactic acid bacteria (LAB) generally considered as favorable microorganism due to their abilities to stimulating host GI development, digestive function, mucosal tolerance, stimulating immune response, and improved disease resistance. In early finfish studies, were culture-dependent methods used to enumerate bacterial population levels within the GI tract. However, due to limitations by using culture methods, culture-independent techniques have been used during the last decade. These investigations have revealed the presence of Lactobacillus, Lactococcus, Leuconostoc, Enterococcus, Streptococcus, Carnobacterium, Weissella, and Pediococcus as indigenous species. Numerous strains of LAB isolated from finfish are able to produce antibacterial substances toward different potential fish pathogenic bacteria as well as human pathogens. LAB are revealed be the most promising bacterial genera as probiotic in aquaculture. During the decade numerous investigations are performed on evaluation of probiotic properties of different genus and species of LAB. Except limited contradictory reports, most of administered strains displayed beneficial effects on both, growth—and reproductive performance, immune responses and disease resistance of finfish. This eventually led to industrial scale up and introduction LAB-based commercial probiotics. Pathogenic LAB belonging to the genera Streptococcus, Enterococcus, Lactobacillus, Carnobacterium, and Lactococcus have been detected from ascites, kidney, liver, heart, and spleen of several finfish species. These pathogenic bacteria will be addressed in present review which includes their impacts on finfish aquaculture, possible routes for treatment. Finfish share many common structures and functions of the immune system with warm-blooded animals, although apparent differences exist. This similarity in the immune system may result in many shared LAB effects between finfish and land animals. LAB-fed fish show an increase in innate immune activities leading to disease resistances: neutrophil activity, lysozyme secretion, phagocytosis, and production of pro-inflammatory cytokines (IL-1β, IL-6, IL-8, and TNF-α). However, some LAB strains preferentially induces IL-10 instead, a potent anti-inflammatory cytokine. These results indicate that LAB may vary in their immunological effects depending on the species and hosts. So far, the immunological studies using LAB have been focused on their effects on innate immunity. However, these studies need to be further extended by investigating their involvement in the modulation of adaptive immunity. The present review paper focuses on recent findings in the field of isolation and detection of LAB, their administration as probiotic in aquaculture and their interaction with fish immune responses. Furthermore, the mode of action of probiotics on finfish are discussed.

“…Moreover diet supplementation with TPB alone significantly increased the regeneration process in the intestine of pigs. Boonanuntanasarn et al [46] investigated the effects of dietary supplementation with inulin and TPB on intestinal microbiota of Nile tilapia fingerlings. Nile tilapia larvae were fed for 12 weeks on experimental diets supplemented with inulin at as dose of 2.5 and 5.0 g/kg, and TPB at 5.0 and 10.0 g/kg from the first feeding.…”

Jerusalem artichoke (Helianthus tuberosus Linne) is a tuberous perennial plant of the Asteraceae family, which originates from North America, and is also known as wild sunflower or topinambur (TPB). It is characterized by good tolerance to frost, drought and poor soil, strong resistance to pests and plant diseases. For ages it was cultivated due to being both an edible tuber and having healing properties. In folk medicine, TPB leaves are used for the treatment of bone fractures and pain. TPB tubers are rich in sugar and have therefore been used for the production of functional food ingredients, such as inulin. Moreover, TPB is one of the potential crops for bioenergy production, such as bioethanol, biobuthanol and biodiesel, and chemicals (lactic acid, butyric acid). A number of bioactive compounds from the above ground parts of this plant have been isolated which have demonstrating antifungal, antioxidant and anticancer activities. In recent years, a number of animal experiments have been carried out to assess the health properties of TPB. Obtained results show that TPB possess a wide spectrum of medical applications, e.g. reduction in the levels of plasma glucose, total cholesterol and triglyceride. Interestingly, TPB has been shown to be a valuable alternative source of prebiotic compounds. This review article presents recent scientific reports on the chemical and biological properties of TPB and its potential use as a prebiotic diet supplement.
