“…Las mejoras en la salud animal bajo condiciones óptimas de nutrición promueven un desempeño favorable frente a condiciones adversas de cultivo y manejo en los organismos en general (Servin et al, 2021). Ante la tendencia del uso de proteína de origen vegetal en acuicultura (El-Naby et al, 2023), particularmente en las dietas de camarón, es de vital importancia evaluar Revista Bio Ciencias 11, e1640.…”

“…Bureau et al (1998) observaron que al agregar 1.5 y 3.0 g de Quillaja saponins por kg de alimento para salmón real (Oncorhynchus tshawytscha) y trucha arcoíris (Oncoryhynchus mykiss) el crecimiento disminuía y les causaba daño en tracto intestinal. A diferencia con camarón blanco P. vannamei donde a las saponinas se les atribuyeron beneficios en crecimiento, mejoras en sus procesos digestivos, microbiota intestinal, estimulación en sistema inmune y/o incremento en sobrevivencia, sin embargo, en la salud del tracto digestivo el beneficio fue limitado (Akbary et al, 2023;Servin et al, 2021). Huang et al (2022) evaluaron el efecto de los compuestos bioactivos en el agua de cultivo con los camarones, concluyendo que al agregarlos una vez por semana en un periodo de 70 días mejoró la tasa de crecimiento específico y crecimiento promedio diario, sin diferencias en sobrevivencia respecto al control.…”

La optimización de técnicas de producción e intensificación en la camaronicultura han diversificado las estrategias en nutrición y salud. La inclusión de aditivos para mejorar resultados es cada vez más común y es de gran importancia evaluarlos adecuadamente. Este estudio realizó un análisis integral sobre el efecto de saponina en juveniles de camarón blanco Penaeus vannamei. Se incluyeron 4 concentraciones de saponina (0%, 2%, 4% y 6%) en una dieta comercial y se alimentaron durante 28 días bajo condiciones controladas de cultivo. El alimento sin saponina (0%) mostró los mejores resultados, el crecimiento fue significativamente diferente (p <0.05) respecto a las demás concentraciones. La sobrevivencia mostró reducción conforme la inclusión de saponina se incrementó, al igual que el daño en tracto digestivo (0%>2%>4%>6%). Las concentraciones evaluadas en este estudio no produjeron mejoras en los camarones, por el contrario, provocaron problemas en su tracto digestivo y en el alimento con mayor proliferación de hongos a mayor inclusión de saponina.

Growth, Health, and Gut Microbiota of Female Pacific White Shrimp, Litopenaeus vannamei Broodstock Fed Different Phospholipid Sources

et al. 2022

Phospholipids have an important antioxidant effect on animals. The effects of different dietary phospholipid sources on the growth, antioxidant activity, immunity, and gut microbiota of female broodstock of Pacific white shrimp Litopenaeus vannamei were investigated. Four isoproteic and isolipid semi-purified diets containing 4% soybean lecithin (SL), egg yolk lecithin (EL), or krill oil (KO) and a control diet without phospholipid supplementation were fed to female broodstock of L. vannamei (34.7 ± 4.2 g) for 28 days. The growth performance, antioxidative capacity, and innate immunity of the female broodstock fed phospholipid supplemented diets were improved regardless of sources compared with the control shrimp. The effects on growth and antioxidant capacity in female shrimp fed the KO diet were highest. The innate immunity of female shrimp fed the EL and KO diets were significantly higher than shrimp fed the SL diet. Dietary phospholipid supplementation increased gut microbiota diversity and richness, and the Chao1 and ACE values in the KO group were significantly higher than in the control group. The richness of Proteobacteria, Photobacterium, and Vibrio decreased, whereas the richness of Firmicutes and Bacteroidetes increased in the shrimp fed the KO diet compared with the shrimp fed the SL and EL diets. The interactions of gut microbiota in shrimp fed the KO diet were the most complex, and the positive interaction was the largest among all the treatments. The functional genes of gut microbiota in shrimp fed the KO diet were significantly enriched in lipid metabolism and terpenoid/polyketide metabolism pathways. Spearman correlation analysis showed that Fusibacter had significantly positive correlations with antioxidant activity (total antioxidant capacity, superoxide dismutase, glutathione peroxidase), immune enzyme activity (phenoloxidase and lysozyme), and immune gene expression (C-type lectin 3, Caspase-1). All findings suggest that dietary phospholipids supplementation can improve the growth and health status of female L. vananmei broodstock. Krill oil is more beneficial in improving the antioxidant capacity and innate immunity than other dietary phospholipid sources. Furthermore, krill oil can help establish the intestinal immune barrier by increasing the richness of Fusibacter and promote the growth of female shrimp. Fusibacter may be involved in iron metabolism to improve the antioxidant capacity of female shrimp.

“…Signi cant correlations were reported between rearing-water bacterial communities and the intestinal microbiota of shrimps in a bio oc-based culture system (Cardona et al, 2016). There has been increasing evidence on the role of gut microbiota on important functions like immunity, health regulation, and nutrient absorption in shrimps (Li et al, 2018, Liu et al, 2019, Servin et al, 2021. Hence, understanding microbial communities present in the culture environment is important in case-control studies to derive causal relations on the manifestation of diseases.…”

Purpose: Stunted/slow growth syndrome is one of the yield-limiting diseases in Penaeus vannamei farming. Limited information is available on the aetiology of this condition, which needs to be studied to devise prophylactic measures to minimise the production losses. Amongst the factors that influence this condition, microbial communities in the growing environment play an important role. This study aimed at understanding major microbial associations of affected and healthy pond waters through shotgun metagenomics.Method: The water samples were filtered through vacuum filtration to extract suspended microbes. Subsequently, DNA was isolated from the filtrate using PowerSoil® DNA Isolation Kit. Libraries prepared from isolated DNA were sequenced using the shotgun metagenomic method on the Illumina HiSeq platform. The microbial profiling and their functional prediction of the shotgun metagenome sequences were carried out using stand-alone versions of Kaiju, OmicsBox respectively. Results: The taxonomic classification results revealed that species of Oceanospirillum, and vibrio were high in the disease sample, while Rhodobacteraceae bacterium and Neptunomonas were high in the healthy sample. The alpha diversity analysis showed slightly higher diversity in the healthy sample compared to the disease infected. The taxonomic biomarkers for healthy and infected states reported in previous studies were also observed in this study. The major functional associations of both the healthy and infected groups include amino acid transport and metabolism, cell wall/membrane/envelope biogenesis, and energy production and conversion. Conclusion: The study identified major taxonomical and functional associations of ponds affected and unaffected with stunted growth syndrome. These associations significantly varied between the samples, indicating dysbiosis of the microbial profiles in the pond waters. This dysbiosis could be a potential cause for the manifestation of stunted growth syndrome. Microbial associations along with other pond environmental factors need to be further explored for an in-depth understanding of stunted growth syndrome.
