OverviewAI-generated summary
Grace Ramena's research focuses on aquatic animal health, particularly the nutritional and physiological aspects impacting fish species. Her work has investigated the effects of dietary iron concentrations on channel catfish (Ictalurus punctatus), examining how different forms of iron influence anemia prevention while also identifying potential negative impacts on liver and intestinal health. This research explores the transferrin and ferritin systems, including gene expression, in response to varying iron levels.
Ramena has also contributed to reviews on nutritional enrichment strategies for aquatic species, with an emphasis on fatty acid profiles. Her recent publications include investigations into the pathobiology of bacterial septicemia in largemouth bass and the modulatory effects of probiotics and immunostimulants on the gut microbiome and immune responses in shrimp (Litopenaeus vannamei). She has co-authored multiple publications with researchers at the University of Arkansas at Pine Bluff, including Yathish Ramena and Rebecca Lochmann, and maintains an active lab website.
