“…Besides, stress factors can significantly affect the GI microbiota (Lesel & Sechet 1982). When different types of chemicals, antibiotics, pollutants like pesticides, herbicides and insecticides enter into the digestive tract of an aquatic animal, they can drastically affect the composition of dominant GI microbiota and may lead to the elimination of individual species from the whole microbial community (Austin & Al‐Zahrani 1988; Sugita, Fukumoto, Koyama & Deguchi 1988; Sugita et al 1989; Syvokiene & Mickeniene 2002; Bakke‐McKellep, Koppang, Gunnes, Sanden, Hemre, Landsverk & Krogdahl 2007; Mickeniene & Syvokiene 2008; Navarrete, Mardones, Opazo, Espejo & Romero 2008).…”

The gastrointestinal (GI) tract of an animal consists of a very complex and dynamic microbial ecosystem that is very important from a nutritional, physiological and pathological point of view. A wide range of microbes derived from the surrounding aquatic environment, soil/sediment and feed are found to colonize in the GI tract of fish. Among the microbial groups, bacteria (aerobic, facultative anaerobic and obligate aneraobic forms) are the principal colonizers in the GI tract of fish, and in some fish, yeasts are also reported. The common bacterial colonizers in the GI tract of freshwater and marine fish include Vibrio, Aeromonas, Flavobacterium, Plesiomonas, Pseudomonas, Enterobacteriaceae, Micrococcus, Acinetobacter, Clostridium, Fusarium and Bacteroides, which may vary from species to species as well as environmental conditions. Besides, several unknown bacteria belonging to Mycoplasma, Arthrobacter, Brochothrix, Jeotgailbacillus, Ochrobactrum, Psychrobacter and Sejongia species in the GI tract of different fish species have now been identified successfully using culture‐independent techniques. Gnotobiotic and conventional studies indicate the involvement of GI microbiota in fish nutrition, epithelial development, immunity as well as disease outbreak. This review also highlights the need for manipulating the gut microbiota with useful beneficial microbes through probiotic, prebiotic and synbiotic concepts for better fish health management.

Abstracts:Aquatic animals are continuously exposed to chemical pollutants but the effects evoked in mucins and the carbohydrate nature of the glycoproteins in the unicellular glands in fish epidermis skin surfaces, which receive the most direct contact with them, has not been fully studied and characterized. Moreover, microorganisms use lectins to recognize and bind to host terminal carbohydrates to facilitate the infection whilst host lectins bind to pathogen carbohydrates to exert protective effector functions, such as agglutination, immobilization, and complement-mediated opsonization and killing of potential pathogens. Thus, terminal carbohydrate composition and the presence of a fucose binding lectin (FBL) were determined by lectin ELISA and western blot, respectively, in skin mucus of gilthead seabream (Sparus aurata L.) specimens exposed to waterborne sublethal dosages of heavy metals [arsenic (As2O3), cadmium (CdCl2) and mercury (CH3HgCl) at 5, 5 and 0.04 μM, respectively] after 2, 10 and 30 days. Results showed little effects of heavy metals in the presence of several terminal carbohydrates with few increments or decrements depending on the sugars, exposure time and heavy metal studied. Moreover, the FBL was undetected in any of the control fish skin mucus but was evident in all the heavy metal exposed fish. Further studies are needed to understand the relation of terminal carbohydrates and lectins in skin mucus fish defense and the implications during contamination exposure.Acknowledgements.
