“…Similar work has been done with the walking catfish ( Clarias spp. ), where bacterial strains with activity against pathogens were isolated from the host species of interest (Paul et al., 2022; Prihanto et al., 2020). A challenge with Aeromonas veronii after a feeding trial indicated walking catfish fed the diet containing an autochthonous Bacillus strain had higher survival than fish fed the basal diet (Paul et al., 2022).…”

Enteric septicemia of catfish (ESC), caused by the gram‐negative enteric bacteria Edwardsiella ictaluri, is a significant threat to catfish aquaculture in the southeastern United States. Antibiotic intervention can reduce mortality; however, antibiotic use results in an imbalance, or dysbiosis, of the gut microbiota, which may increase susceptibility of otherwise healthy fish to enteric infections. Herein, recovery of the intestinal microbiota and survivability of channel catfish in response to ESC challenge was evaluated following a 10‐day course of florfenicol and subsequent probiotic or prebiotic supplementation. Following completion of florfenicol therapy, fish were transitioned to a basal diet or diets supplemented with a probiotic or prebiotic for the remainder of the study. Digesta was collected on Days 0, 4, 8 and 12, beginning on the first day after cessation of antibiotic treatment, and gut microbiota was characterized by Illumina sequencing of the 16S rRNA gene (V4 region). Remaining fish were challenged with E. ictaluri and monitored for 32 days post‐challenge. Florfenicol administration resulted in dysbiosis characterized by inflated microbial diversity, which began to recover in terms of diversity and composition 4 days after cessation of florfenicol administration. Fish fed the probiotic diet had higher survival in response to ESC challenge than the prebiotic (p = .019) and negative control (p = .029) groups.

“…Several studies have reported less LAB obtained from Channa sp., Puntioplites waandersi, and farmed Clarias sp. with only eight, five, and nine bacterial isolates respectively (Agustina et al 2022;Bayu et al 2023;Prihanto et al 2020). Physiological and environmental factors may play a vital role in the LAB diversity among fish species particularly water and feed quality.…”

Abstract. Lingga R, Adibrata S, Roanisca O, Sipriyadi, Wibowo RH, Arsyadi. 2023. Probiotics potential of lactic acid bacteria isolated from Slender Walking Catfish (Clarias nieuhofii). Biodiversitas 24: 4572-4580. Probiotics are living microorganisms or bioactive agents that positively impact animal digestion. They have successfully isolated from various sources. Recently, we isolated and characterized lactic acid bacteria (LAB) from slender walking fish (Clarias nieuhofii Valenciennes, 1840). The fish sample was obtained from Batu Rusa and Paya Benua Rivers in Bangka Island, Indonesia. LAB was isolated from the fish intestine using the pour plate method. The isolated LAB was then characterized based on their phenotypic traits, biochemical properties, and the 16S rRNA gene identification. The chosen isolates were tested to determine their ability to produce lactic acid, hemolytic and antibacterial activity, and antibiotic resistance. All isolates have the characteristic of rod-shaped and short rod-shaped cells with Gram-positive properties. Isolate KP1 showed the number of populations (2.89 x 107 CFU/mL) and lactic acid production with a concentration of 1.85%. All isolates exhibited no hemolysis activity and displayed sensitivity to antibiotics. The twelve lactic acid bacteria formed clear zones against Staphylococcus aureus and Escherichia coli. The results of the 16S rRNA gene identification indicated that isolates KB4, KB7, KB8, and KP1 belong to Lactobacillus vaginalis, Lactobacillus fermentum, Limosilactobacillus fermentum, and Levilactobacillus brevis, respectively. Lactic acid bacteria isolated from slender walking fish exhibited potential probiotic traits.
