“…A comprehensive review of the immunomodulatory activity of probiotics and the factors that induce immune response in fish has been recently published (Nayak 2010a). Although it is important to use selected organisms of the normal dominant gut microbiota of the species under concern as probiotics, it has been difficult to detect beneficial and specific microorganisms in the fish gut (Nakano 2007), and this complicates the selection of microbiota to be used as effective probiotics.…”

“…A wide range of microalgae, yeasts and bacteria have been evaluated as probiotics (Irianto & Austin 2002), although most probiotics used in aquaculture are bacteria (Verschuere, Rombaut, Sorgeloos & Verstraete 2000; Irianto & Austin 2002; Burr, Gatlin & Ricke 2005; Nakano 2007; Merrifield et al. 2010; Nayak 2010b).…”

“…Prebiotics are non‐digestible feed ingredients, including oligosaccharides and dietary fibre that promote growth of beneficial gut microbes and depress the proliferation of harmful microbes (Burr et al. 2005; Nakano 2007; Ringo, Olsen, Gifstad, Dalmo, Amlund, Hemre & Bakke 2010b), or enhance intestinal immunity (Delzenne 2003). While health benefits of probiotics are relatively well documented, that of prebiotics is more limited (Ringo et al.…”

“…The influence of probiotics and prebiotics on fish is still largely unknown, and this also applies to the action of mixtures of probiotics or prebiotics and possible interaction between these functional foods (Nakano 2007). Indeed, so far most studies on probiotics analysed single microorganisms, and this can be less effective than using probiotic mixtures (Verschuere et al.…”

Under intensive culture conditions, fish are subject to increased stress owing to environmental (water quality and hypoxia) and health conditions (parasites and infectious diseases). All these factors have negative impacts on fish well-being and overall performance, with consequent economic losses. Though good management practices contribute to reduce stressor effects, stress susceptibility is always high under crowded conditions. Adequate nutrition is essential to avoid deficiency signs, maintain adequate animal performance and sustain normal health. Further, it is becoming evident that diets overfortified with specific nutrients [amino acids, essential fatty acids (FAs), vitamins or minerals] at levels above requirement may improve health condition and disease resistance. Diet supplements are also being evaluated for their antioxidant potential, as fish are potentially at risk of peroxidative attack because of the large quantities of highly unsaturated FAs in both fish tissues and diets. Functional constituents other than essential nutrients (such as probiotics, prebiotics and immunostimulants) are also currently being considered in fish nutrition aiming to improve fish growth and/or feed efficiency, health status, stress tolerance and resistance to diseases. Such products are becoming more and more important for reducing antibiotic utilization in aquafarms, as these have environmental impacts, may accumulate in animal tissues and increase bacterial resistance. This study reviews knowledge of the effect of diet nutrients on health, welfare and improvement of disease resistance in fish.

“…However, this caused various problems such as the presence of antibiotic residues in animal tissues, the generation of bacterial resistance mechanisms, as well as an imbalance in the gastrointestinal microbiota of aquatic species, which affected their health [88]. In fact, the European Union has regulated the use of antibiotics in organisms for human consumption [89].…”

The growth of aquaculture as an industry has accelerated over the past decades; this has resulted in environmental damages and low productivity of various crops. The need for increased disease resistance, growth of aquatic organisms, and feed efficiency has brought about the use of probiotics in aquaculture practices. The first application of probiotics occurred in 1986, to test their ability to increase growth of hydrobionts (organisms that live in water). Later, probiotics were used to improve water quality and control of bacterial infections. Nowadays, there is documented evidence that probiotics can improve the digestibility of nutrients, increase tolerance to stress, and encourage reproduction. Currently, there are commercial probiotic products prepared from various bacterial species such as Bacillus sp., Lactobacillus sp., Enterococcus sp., Carnobacterium sp., and the yeast Saccharomyces cerevisiae among others, and their use is regulated by careful management recommendations. The present paper shows the current knowledge of the use of probiotics in aquaculture, its antecedents, and safety measures to be carried out and discusses the prospects for study in this field.
