| Abstract | ||
| The gnotobiotic approach utilizing autochthonous probiotics enhance the growth and immunity by fastening to persist in the fish’s gastrointestinal tract. The present work was conducted to examine the adherence and colonization of probiotics, Aneurinibacillus aneurinilyticus, and Stenotrophomonas sp. fed to Labeo calbasu. The juveniles were fed on Diet C (control), Diet 1 (A. aneurinilyticus), Diet 2 (Stenotrophomonas sp.), and Diet 3 (A. aneurinilyticus and Stenotrophomonas sp.) maintained in triplicate with ten individuals each for a duration of 90 days. The fingerlings depicting significant growth performance (p < /em><0.05) were subjected to intestinal enzymatic, haematological, and immunohistochemical assays. Diet 1 fed group revealed significantly (p < /em><0.05) high values of enzymes, blood corpuscles, and respiratory burst activity. The results showed the permanence of probiotic colonies in gastrointestinal tract lumen and on the microvilli edges. This clearly reveals that probiotic A. aneurinilyticus enhanced growth, digestibility, and immune response providing an appreciable approach towards sustainable aquaculture. | ||
