Comparative study of host-associated and commercial probiotic effects on serum and mucosal immune parameters, intestinal microbiota, digestive enzymes activity and growth performance of roach (Rutilus rutilus caspicus) fingerlings

Host‐associated Bacillus siamensis and Lactococcus petauri improved growth performance, innate immunity, antioxidant activity and ammonia tolerance in juvenile Japanese seabass ( Lateolabrax japonicus )

“…In this study, above 93.33% SR was recorded in both control and treated groups, indicating that the five selected potential probiotics are safe for Japanese seabass (L. japonicus). The result is in accord with recent studies indicating that application of host-associated potential probiotics is generally harmless to the host health (De Moraes et al, 2018;Doan et al, 2018;Paixao et al, 2020;Tarkhani et al, 2020;Zhu et al, 2021). The growth improvement effect of probiotics has been reported in many fish species, such as grouper (Epinephelus coioides) (Liu et al, 2012;Sun et al, 2010), Nile tilapia (Oreochromis niloticus) (Doan et al, 2018;Kuebutornye et al, 2020;Tang et al, 2020), roach (Rutilus rutilus caspicus) (Tarkhani et al, 2020), rainbow trout (Oncorhynchus mykiss) (Mohammadian et al, 2019;Safari et al, 2016) Abbreviations: C3, complement 3; GOT, glutamic-oxalacetic transaminase; GPT, glutamic-pyruvic transaminase; IgM, immunoglobulin M. used probiotic genera in aquaculture.…”

“…As alternatives to antibiotics, antimicrobial peptide, herb extracts, pro-, pre-and syn-biotics have been applied as feed additives for the prevention or treatment of various stresses and diseases of aquatic animals, and among them, probiotics have attracted wide attention because of their satisfactory effects, low cost, and convenience in application (Hoseinifar et al, 2018). It is extensively reported that administration of probiotics can improve the growth performance, immune response, digestive enzyme activities, intestinal health and tolerance to ambient stress in fish (Beck et al, 2015;Dawood et al, 2016;De Moraes et al, 2018;Paixao et al, 2020;Tarkhani et al, 2020;Zhu et al, 2021). However, screening of probiotic strains is the primary step to their successful application because not all probiotics can gain positive effects in aquatic animals.…”

Protective Effects of Non-Encapsulated and Microencapsulated Lactobacillus Delbrueckii Subsp. Bulgaricus in Rainbow Trout (Oncorhynchus Mykiss) Exposed to Lead (Pb) Via Diet

“…It is well established that use of dietary probiotics can positively affect on the growth of fish through stimulation of appetite, elevation of digestive enzymes activity, regulation of the population of the gut microflora, modification of the intestinal morphology, promotion of feed utilization and provision of micronutrients (Salinas et al, 2008;Suzer et al, 2008;Pinpimai et al, 2015;Tarkhani et al, 2020). In this study, feeding of fingerling trout with diets containing non-encapsulated or microencapsulated L. delbrueckii subsp.…”

“…Likewise, administration of Lactobacillus spp. can positively alter the antioxidant defense system of fish through regulation of antioxidant-dependent signaling pathways (Hoseinifar et al, 2020;Kong et al, 2020). Prior to exposure to lead, the enhancement of activities of serum SOD was observed in fish fed with dietary non-encapsulated and microencapsulated L. delbrueckii subsp.…”

Probiotics in Fish Nutrition—Long-Standing Household Remedy or Native Nutraceuticals?

“…Probiotics also convert less degradable compounds into forms that can be easily digested by the host (Figure 2). Here, various microbial enzymes, such as lipases, phytases, amylases, cellulases, trypsin, and other proteases, can be involved [93][94][95][96][97]. In addition, microbes can stimulate the activity and secretion of host enzymes directly [98][99][100].…”
