ABSTRACT The microbiota composition of healthy farmed fishes remains poorly characterized for many species. This study explores the influence external environment and innate factors that may shape gut Asian seabass, Lates calcarifer . α-diversity based on Shannon, Simpson, Chao1 indices was lower reared in sea cages tanks than experienced a transfer from to tanks. Longitudinal analyses segments revealed no significant differences alpha diversity between within same containment type, except index stomach pyloric cecum sea-caged fishes. β-diversity analysis using weighted UniFrac distance Bray-Curtis dissimilarity demonstrated fish type shared similar microbial communities. PERMANOVA tests confirmed farm, batch significantly influenced these distances. Containment accounted 10.4% observed diversity, farm 29.8%, 10.7%. Genera comprising potential pathogens such as Aeromonas , Flavobacterium Vibrio were differentially abundant along guts different types particularly increased Microbiota changes with host age segment, genera identified seabass grew. Comparing hindgut other species host-specific clustering indicated by PERMANOVA. Overall, findings underscore significance conditions broad implications aquaculture practices. IMPORTANCE Understanding is crucial optimizing highlights ( ). By demonstrating community are shaped location, batch, research provides valuable insights into how environmental interact health. findings, differential abundance various types, need tailored management strategies aquaculture. not only advances our knowledge but also has improving sustainability productivity

Effect of Moringa oleifera, Bacillus amyloliquefaciens, and Their Combination on Growth Performance, Digestive Enzymes, Immunity, and Microbiota in Nile Tilapia (Oreochromis niloticus)

Aquaculture Nutrition, Journal Year: 2024, Volume and Issue: 2024(1)

Published: Jan. 1, 2024

To exploit aquatic animals’ feed resources and functional ingredients additives, this experiment investigated the effects (a 2 × factorial trial) mechanism of woody plants probiotics on Nile tilapia. Each treatment group was randomly assigned triplicate nets 40 fish (initial body weight 35.04 ± 0.01 g) in 12 tanks for 56 days. Fish were fed four diets, including a CON–CON diet (with no supplementation) CON–Ba (basal + 1 10 7 CFU/g B. amyloliquefaciens ), MO‐CON 10% Moringa oleifera ) MO‐Ba until apparent satiation (2 meals/day). The results showed that MO had lower conversion ratio than non‐MO diets ( P < 0.05). gain Ba significantly higher those groups without Both improved morphological indices when applied individually supplementation activities digestive enzymes upregulated gene expression TNF-α , IL-6 IL-10 C3 spleen tilapia 0.05), while IL ‐6 microbiological analyses abundances beneficial bacteria increased, relative pathogenic decreased fish‐fed MO. In conclusion, dietary can effectively improve immunity tilapia, enhance enzymes. synergistic effect intestinal microbiota promotes growth, thus showing promising application prospects.

Impact of transport conditions and underlying disease on post‐stocking survival of juvenile Lates calcarifer

Journal of Fish Diseases, Journal Year: 2024, Volume and Issue: 47(8)

Published: May 24, 2024

Diseases caused by pathogens commonly occurring in the aquatic environment or those that are non-host specific prevalent and threaten rapid growth of tropical aquaculture. This study investigates causes mortality 12 batches newly stocked juvenile Lates calcarifer from three different hatcheries. Cytology based on Diff-Quik™-stained tissue blood smears provides diagnosis possible mortality, while histopathology haematology provide a better understanding how prolonged transport fish with existing chronic disease more likely to experience elevated post-stocking. Our findings showed accumulation ammonia during extensive damage epithelial barriers gastrointestinal tracts depressed immunity due marked hypoglycaemia, predisposing acute Streptococcosis. bacterial enteritis developed severe had low circulating total plasma protein, suffered high within 24 hours Hypoglycaemia proteins disrupt osmoregulation exacerbate dehydration, which is fatal sea water. Dying L. tested PCR positive for scale drop virus (SDDV) at 28 days post-stocking 10-fold elevation white cell counts, vasculitis, obstruction supply major organs. Destruction important immune organs such as spleen hallmark SDDV infection explains incidences opportunistic Vibrio harveyi infections 61% SDDV. Overall, this reiterates importance stocking disease-free reducing stress.
