Abstract

Global food security depends heavily on aquaculture, especially in developing countries where shrimp aquaculture is becoming a major source of both food and economic prosperity. However, disease outbreaks, including those brought on by Vibrio species, present serious obstacles to shrimp farming, leading to economic losses and the rise of diseases resistant to an bio cs. This study uses Artemia franciscana as a model organism to inves gate how bacterial priming may improve disease resistance. Significant results show how crucial it is to improve culture condi ons, such as using nutrient-rich feed and water loaded with microbiota, in order to enhance Artemia health, development, and reproduc on. According to experimental data, live bacterial priming using Vibrio campbellii superiors dead bacterial priming in terms of improving survival, growth, swimming ac vity, and reproduc ve success. When compared to non-homologous priming, homologous priming offered be er defense against ensuing pathogen challenges, underscoring the specificity of Artemia immune response. Addi onally, live priming maintained long-term immunological and physiological advantages and decreased stress signs like hypermelaniza on. The results highlight how crucial it is to combine live, homologous pathogen priming with improved culture techniques in order to create viable aquaculture systems. These methods might improve aquaculture systems' resilience and produc vity while reducing disease outbreaks. The molecular processes behind immune priming and its long-term impacts on Artemia and shrimp popula ons deserve to be the main topics of future studies. This study emphasizes how crea ve, sustainability disease control techniques may promote environmentally friendly aquaculture methods across the world.
