Abstract

This paper presents a first report of the successful identify Dietary Synbiotic Assessment on The Quantitative Growth Effect of The Hybrid Catfish (Clarias microstomus ♂ x Clarias gariepinus ♀) from August 2022 to January 2023. The study was carried out at the Virology laboratory of Parasitology and laboratory Post-Mortem Department of Animal Sciences and Fisheries laboratory in the Faculty of Agricultural and Forestry Sciences UPMKB, Sarawak. Introduction: The successful hybridization between Clarias microstomus (Ng, 2001) ♂ x Clarias gariepinus (Burchell,1822) ♀ brooder to experiment. There were four experimental diets tested in this study: T1- (108 CFU/g L1M10 + inulin): T2- (108 CFU/g L4AM2+ inulin); i) T3- (108 CFU/g L4AM5+ inulin) and T4- negative control. The fish were weighed individually at the experiment's beginning and end. Then, three fish were randomly chosen from each tank to measure the weight at the beginning (twice every 14 days) at the end of the experiment. The bacteria were identified phenotypically (Gram staining, biochemical tests) and genotypically by (GTG)5 PCR fingerprinting. problem statement: Previously, various study has been conducted using other species, especially African catfish, but there needs to be more knowledge of the local catfish. Hence, this objective is to evaluate the effect of synbiotic dietary supplementation. There is no sufficient data regarding the breeding and dietary information for the new catfish (Clarias microstomus ♂ x Clarias gariepinus ♀). Due to high demand, synbiotic application in dietary feed can uplift fish productivity, immune system and gut health. Objectives: There needs to be more data on the breeding and dietary habits of the new catfish (Clarias microstomus x Clarias gariepinus). Using synbiotics in dietary feed can improve fish productivity, immune system, and gut health. To our knowledge, no breeding or synbiotic research has been conducted on this hybrid catfish (Clarias microstomus x Clarias gariepinus). Conclusion: Our study proposed the use of these LAB isolates from the gut of hybrid catfish as potential synbiotics agents to enhance the immunity and growth in the hybrid catfish.
