New slow-sinking probiotic wafers simplify application while improving gut health, survival, and operational efficiency in fish nursery systems.
At the World Aquaculture Society (WAS) Singapore 2026 tradeshow, INVE Aquaculture, a global biotechnology company specialized in innovative solutions for aquaculture, announced the launch of Sanolife™ PRO-TAB, a next-generation probiotic wafer designed to enhance fish health, resilience, and survival during the critical nursery and pre-growing stages.
The nursery stage represents one of the most sensitive phases in fish production. Mortality can increase during this period, and it has been scientifically proven through numerous trials that the use of probiotics in the water or better yet, mixed with feed can significantly reduce mortality. However, applying these probiotics in feed is not always easy, and hatchery and nursery operators often face challenges such as inconsistent probiotic intake, leaching of active ingredients in water, labour-intensive preparation methods. Sanolife™ PRO-TAB addresses these challenges through a novel delivery technology that ensures reliable probiotic intake while simplifying daily farm operations.
Sanolife™ PRO-TAB is formulated as slow-sinking wafers containing a high concentration of Bacillus probiotics, enabling targeted delivery directly to the fish gut. The wafers feature advanced coating technology that prevents nutrient leaching and preserves probiotic viability in water, ensuring consistent and effective probiotic intake.
“Fish farmers increasingly need solutions that combine biological performance with operational simplicity,” said Thomas Raynaud, Product Manager Formulated Diets at INVE Aquaculture. “Sanolife™ PRO-TAB represents a new generation of probiotic delivery technology that ensures consistent intake, supports gut health, and helps farmers manage the critical nursery stage with greater confidence and efficiency.”
To ensure this reliability, INVE’s R&D teams focused on optimizing both the probiotic formulation and the delivery system.
“Traditional probiotic applications in aquaculture often struggle with stability and consistent ingestion,” said Barbara Hostins, R&D Lead Health at INVE Aquaculture. “With Sanolife™ PRO-TAB, we designed a delivery system that protects probiotic spores, prevents nutrient leaching, and ensures the active ingredients effectively reach the fish gut. By combining targeted Bacillus strains with a stable wafer matrix, we support microbiota balance and fish resilience in a much more reliable way.”
The wafers also feature high attractancy, stimulating feeding behaviour and encouraging fish to detect, pursue, and ingest the wafers during the sinking phase. This ensures reliable probiotic consumption while supporting improved feeding efficiency and cleaner systems.
Designed for operational practicality, Sanolife™ PRO-TAB requires no top-coating preparation and can be applied either manually or through automatic feeders, significantly reducing labour requirements and minimizing the risk of human error compared with traditional probiotic powders or tablets.
“In the nursery phase, fish are particularly vulnerable to stress events such as grading, handling, and environmental fluctuations which will cause immune depression and therefore greater susceptibility to bacterial attacks,” said Valentina Carbone, Global Technical Expert Fish at INVE Aquaculture. “A solution like Sanolife™ PRO-TAB helps farmers bridge that sensitive period by ensuring fish consistently ingest probiotics while maintaining strong feeding behaviour and pathogenic bacteria resistance. In practice, this translates into healthier fish, improved survival, and more stable nursery performance.”
Sanolife™ PRO-TAB is available in two wafer sizes — 2 mm for early nursery fish and 5 mm for pre-growing fish — supporting fish from approximately 2 g to 80 g. With excellent water stability and consistent probiotic delivery, the product supports improved survival, growth, and resilience throughout nursery cycles.
By strengthening gut microbiota and supporting fish resilience under stress conditions, Sanolife™ PRO-TAB complements modern health management strategies in hatcheries and nurseries. At the same time, the product contributes to improved feed utilization, reduced waste, and more stable production outcomes.
