The 10th International Symposium on Sturgeon (ISS10)

Precision nutrition in sturgeon farming tailors feed to optimize metabolic pathways and gut microbiota, enhancing growth and caviar quality. By activating pathways like PPAR (master gene of fat metabolism), it improves energy efficiency, sparing protein for immune function and growth. Simultaneously, the mTOR pathway (master gene of protein metabolism) is targeted to maximize protein synthesis. The gut microbiome acts as a vital organ, producing bioactive metabolites that boost health. This strategy dynamically adjusts for environmental factors like temperature, aiming to maximize the fish's genetic potential for efficient, high-yield production. The physical and durability parameters of pellets are critical for feeding behavior and nutrient intake, as fish preferences are not defined by human perceptions of taste or smell. Precision nutrition optimizes fish feed by aligning nutrient delivery with the fish's genetics, fish acceptance, and environment, maximizing growth efficiency (FCR) while minimizing waste output. This approach tailors diets to unlock genetic potential under specific farming conditions.
