“…The larger the two values, the greater the total number of species contained in the sample. Shannon index and Simpson index are used to calculate bacterial diversity, and the larger the two values, the higher the species diversity 60 . The results of this experiment showed no significant changes in Shannon index and Simpson index values, indicating that the species richness of the gut microbiota was altered but its diversity was unchanged.…”

In this study, Penaeus monodon were gave basic feed supplemented with three levels of Enterococcus faecium. Then, the expression of non-specific immunity-related genes, and the activities of total antioxidant capacity (T-AOC), superoxide dismutase (SOD), malondialdehyde (MDA), acid phosphatase (ACP), alkaline phosphatase (AKP), phenol oxidase (PO) were evaluated. Meanwhile, the disease resistance test and intestinal flora determination were conducted. The results showed that the MDA levels of 2% and 5% E. faecium groups were significantly lower than that of the control group (P < 0.05). While the SOD and T-AOC and ACP and AKP of experimental groups were significantly higher (P < 0.05), the PO of experimental groups were significantly lower than that of the control group (P < 0.05). In addition, the expressions of immunity-related genes (tlr22, dorsal, lysozyme, crustin, imd, and relish) in the 2% and 5% E. faecalis groups were significantly greater than those in the control group (P < 0.05). After P. monodon was challenged with Vibrio parahaemolyticus for 7 days, the average cumulative mortality of P. monodon in the 2% and 5% groups were significantly lower than that in the 0% group (P < 0.05). With the increase of feeding time, the number of effective OTUs in each group showed a downward trend. At the 14th d, Proteobacteria, Bacteroidetes and Firmicutes, the dominant flora in the intestinal tract of P. monodon. In summary, supplied with E. faecium could increase the expression of non-specific immunity-related genes, enhance the immune capacity of P. monodon.

“…Growth performance is an important parameter of vannamei shrimp culture due to the cost and time involved in growing shrimp from a small size to a consumption size [10][11][12]38]. Growth performance parameters include specific growth rate, final body weight, weight gain, feed efficiency, and feed conversion ratio (FCR) [41,42].…”

“…Table-1 also provides information regarding the increased survival rates found in vannamei shrimp with probiotic use. Probiotics help shrimp meet their nutritional needs[ 57 ], which helps to protect the organism from stress, malnutrition, and death [ 11 ]. The survival rate is an important indicator of successful shrimp cultivation since it directly affects the number of shrimps sold and the farmer’s profits.…”

The role of probiotics in vannamei shrimp aquaculture performance – A review

et al. 2023

View full text Add to dashboard Cite

Vannamei shrimp (Litopenaeus vannamei) is an important food commodity of economic benefit due to its high price, low susceptibility to disease, and popularity for consumption. These advantages have led many farmers to cultivate vannamei shrimp. Efforts are underway to improve the aquaculture performance of this species, including the use of probiotics, which are non-pathogenic bacteria that aid in digestion and help fight disease. Probiotics are usually obtained from the intestines of vannamei shrimp or the culture environment. They are low-cost, non-pathogenic, and largely non-toxic source of antibiotics and are able to synthesize various metabolites that have antibacterial functions and applications. Research on probiotic use has primarily been focused on increasing vannamei shrimp aquaculture production. Bacterial species, such as Lactobacillus or Nitrobacter, can be administered orally, by injection, or as a supplement in aquaculture water. Probiotics help to improve survival rate, water quality, immunity, and disease resistance through space competition with disease-causing bacteria, such as Vibrio spp. An increased number of probiotic bacteria suppresses the growth and presence of pathogenic bacteria, which lowers disease susceptibility. In addition, probiotic bacteria also aid digestion by breaking down complex compounds into simpler substances that the body can absorb more easily. This mechanism improves growth performance in terms of weight, length, and feed conversion ratio. This review aimed to provide information regarding contribution of probiotic to improve vannamei shrimp production in aquaculture. Keywords: application, bacteria, farm, microbiome, shrimp.

“…As a consequence, aquaculturists, in particular in Southeast Asia, are constantly trying to improve culturing conditions of this species, in attempts to raise production and thus to enhance yields (Manan & Ikhwanuddin, 2021). One aspect of such improvements could be found in influencing the gut microbiota of P. vannamei, which may lead to better health conditions of the shrimp and thus enhance survival (El-Saadony et al, 2022). In the present study, the use of moringa for improving the gut microbiota of these shrimps has been investigated.…”

This study evaluated the potential of the aqueous moringa (Moringa oleifera) leaf extract (ME) as a prebiotic and its effect on the growth performance of the whiteleg shrimp, Penaeus vannamei Boone, 1931. The growth trial of probiotics in the broth containing ME showed that Lactobacillus acidophilus growth rate was significantly higher () than that of Lactobacillus plantarum and Lactobacillus reuteri. Furthermore, L. acidophilus exhibited also better growth () than Vibrio alginolyticus, Vibrio parahaemolyticus and Vibrio harveyi in the broth containing ME. The minimum inhibitory concentration of ME (MIC) and minimum bactericidal concentration (MBC) were the same against V. alginolyticus, V. parahaemolyticus, and V. harveyi at concentrations of 10, 7.5, and 7.5 mg/ml, respectively. By contrast, ME’s MIC and MBC against L. acidophilus were 50 and >100 mg/ml, respectively. The prebiotic scores of L. acidophilus against V. parahaemolyticus and V. harveyi were significantly higher () than that against V. alginolyticus. The MIC, MBC, and prebiotic scores indicated that ME enhanced the growth of L. acidophilus more than that of Vibrio bacteria. Six diets were formulated for the feeding trial; 3 diets contained ME at 0 (ME0), 2.5 (ME2.5) and 5.0 g/kg (ME5.0), respectively, and the same 3 diets were also prepared with L. acidophilus (ME0 + P, ME2.5 + P, and ME5.0 + P, respectively). After the feeding trial, the number of lactic acid bacteria in the gut was higher () in the ME2.5 + P group than in the control and ME2.5 groups, but no differences were found in the vibrio-like bacterial count among the treatments. The ME2.5 + P group had a higher () final weight, weight gain, and specific growth rate than did the ME or L. acidophilus alone and the control groups. Therefore, ME exhibits a prebiotic function and exerts a symbiotic effect with L. acidophilus, thus increasing the growth performance of P. vannamei.
