“…Probiotics can alter the intestinal immunology and morphology towards a more tolerant and less inflammatory mucosa (Ringø et al, 2007;Lazado and Caipang, 2014), ameliorating the epithelial barrier function (Madsen et al, 2001). Probiotics can also provide nutrients, digestive enzymes (Ray et al, 2012) and enhance the absorptive surface area through longer villi (Pirarat et al, 2011) and longer (Merrifield et al, 2010) and denser microvilli (Standen et al, 2015). Some experiments report the stimulation of systemic innate defences as plasma lysozyme, complement or respiratory burst by probiotic microorganisms (Balcazar et al, 2007) and their implication in the oxidative stress response (Castex et al, 2009;Ozório et al, 2016).…”

Probiotic administration can be a nutritional strategy to improve the immune response and growth performance of fish. The current study aimed to evaluate the effects of a probiotic blend (Bacillus sp., Pediococcus sp., Enterococcus sp., Lactobacillus sp.) as a dietary supplement on growth performance, feed utilization, innate immune and oxidative stress responses and intestinal morphology in juvenile Nile tilapia (Oreochromis niloticus). The probiotic was incorporated into a basal diet at three concentrations: 0 g/kg (A 0 : control), 3 g/kg (A 1 : 1.0 × 10 6 colony forming unit (CFU)/g) and 6 g/kg (A 2 : 2.3 × 10 6 CFU/g diet). After 8 weeks of probiotic feeding, weight and specific growth rate where significantly higher in fish-fed A 1 diet than in fish-fed A 0 . Alternative complement in plasma was significantly enhanced in fish-fed A 2 when compared with A 0 . The hepatic antioxidant indicators were not affected by probiotic supplementation. Villi height and goblet cell counts increased significantly in the intestine of fish-fed A 1 and A 2 diets compared with A 0 . The dietary probiotic supplementation was maintained until 20 weeks of feeding. Then the selected immune parameters, digestive enzymes and apparent digestibility of diets were studied. No effect of probiotic feeding was observed after that longer period supplementation. The dietary supplementation of mixed species probiotic may constitute a valuable nutritional approach towards a sustainable tilapia aquaculture. The improvement of the immune responses and intestinal morphology play an important role in increasing growth performance, nutrient absorption and disease resistance in fish, important outcomes in such a competitive and developing aquaculture sector.

“…The gastro intestinal tract (GIT) is a home to complex and dynamic microbial ecosystem, the composition of which differs between individual and gastrointestinal location and time. It provides pivotal stimuli for the development of the host immune system and physiology such as gastric development, differentiation and its integrity (Merrifield et al, 2010a). The main function of the microbiota (immense number of micro-organisms) includes degrading dietary compounds, influencing nutrient partitioning and lipid metabolism, providing essential nutrients generated as a result of microbial metabolism, protecting against invading pathogens and stimulating gut morphology (Mulder et al, 2009).…”

“…Gastric pathogen has to overcome or colonise the mucus layer in order to attach, interact with and infect the host epithelium (Merrifield et al, 2010a). Because the intestinal mucosal barrier including the epithelium cells, tight junctions controlling the paracellular pathways and a superficial mucous layer forms an effective physical barrier that separate the individual from the complex microbial populations which constitute the normal intestinal microflora (Ringo and Birkbeck, 1999).…”

“…Antagonism may arise because of competition for nutriaents that favour the growth of probiotics strain or the expression of their inhibitory effects in the gastro intestine (Gatesoupe, 1999). Mucus-associated populations of probiotics are likely to provide competition, release bacteriocins and other antimicrobial compounds in the mucus layer and exert a host immuno-stimulatory role (Merrifield et al, 2010a). An example is production of bacteriocins from lactic acid bacteria, which can inhibit the growth of fish pathogens such as Vibrio anguillarum and Aeromonas salmonicida (Gildberg, et al, 1997).…”

The use of probiotics in feed for fish and its inclusion in intensive aquaculture to promote healthy gut is growing. The need for alternative measures that will perform closely and effectively to the use of antibiotics after its annulment in European Union (EU) in 2006 is an issue which call for concern. Several definitions of probiotics mainly for aquaculture were also dig out from published papers. Among them is a definition considered appropriate for aquaculture which is described as" any microbial cell provided via the diet or rearing water that benefits the host fish, fish farmer or fish consumer, which is achieved, in part at least, by improving the microbial balance of the fish". In this context, they regard direct benefits to the host as immuno-stimulants, improved disease resistance, reduced stress response, improved gastro intestinal morphology and benefits to the fish farmer or consumer. The benefits to the fish farmer and consumers includes improved fish appetite, growth performance, feed utilization, improvement of carcass quality, flesh quality and reduced malformations. The mode of action with benefits of probiotics in aquaculture from published journals was also looked into. The use of probiotics is growing especially as new strains were being discovered that can withstand processing stress in feed manufacturing. But process optimization knowledge to effectively work with these additives is insufficient. Combination of strain isolated from the gastro-intestinal (GI) tracts of host animal had also being proving to be effective. Need to find proper parameters to work with probiotics will be of great importance to the feed industry in the near future and the stability of the strains of probiotics as a synbiotic relation with prebiotics. Examples and effects of known strains were also stated and the future perspective of probiotics for fish.

“…Gatesoupe [32] surmised persistency of probiotics supplemented either daily or continuously in various fish species and shellfish is greatly varied. To improve persistency of probiotics, and for safety reasons, it is widely accepted that host origin (autochthonous) strains, especially mucus inhabitants [33][34][35][36] with probiotic properties, offer improved safety, ability to colonise and multiply, and can remain predominant and persist in the same host [32,37,21,24,38] after changing to basal diets [1] compared to commercial probiotic supplemented diets [39].…”

The present study examined the health status of marron Cherax cainii after feeding with a customised probiotic B. Mycoides supplemented diets at various feeding period by measuring intestinal bacterial population, hepatosomatic indices (Hiw), total haemocyte count (THC), bacteraemia and survival rate. During a 6 week feeding trial, the marron were fed at a rate of 1.5 % of the total biomass per day with a commercial marron feed (basal diet) and B. mycoides (10 8 CFU/g of feed) supplemented diet. The first group of marron was solely fed on the basal diet while group two, three and four were fed with supplemented probiotic for one week, two weeks and four weeks, respectively before changing to the basal diet only.The results suggested that intestinal bacterial population was higher in the probiotic fed groups compared to the basal diet fed marron. Among the probiotic fed groups, the highest intestinal bacterial population was observed in marron fed probiotic for four weeks. In addition, Hiw of the marron fed probiotic for four weeks was also higher than other feeding groups, whereas Hiw of basal diet fed marron was significantly lower compared to probiotic fed groups. No mortality was observed in any feeding group.The longest probiotic feeding period (four weeks) resulted in a higher immune status as indicated by higher THC and lower bacteraemia. However, after shifting to a basal diet, a reduced intestinal bacterial population, Hiw and THC were observed in all groups, except bacteraemia. In conclusion, periodic or continues probiotic B. Mycoides feeding is required to maintain its high population levels and better health benefits in marron.
