Finally, great news for marine fish hatcheries: Reduce live rotifer diets by at least 50% with Natura pRo and ExL

We proudly introduce Natura pRo and ExL: the revolutionary feedline and protocol, substituting rotifers seamlessly. Until now, hatcheries had to use rotifers, which resulted in high operational costs and efforts, variable quality, and insecure results. Natura pRo and ExL are addressing this important – and until yesterday – unsolved challenge. This rotifer substitution challenge has been the priority for INVE (Benchmark Advanced Nutrition) for many years. Steven Debono, Product Manager Fish Hatchery, explains: Natura pRo and ExL are the novel solution to rotifer substitute. They lead towards improved survival, larvae quality and operational flexibility for marine fish hatcheries.

“At INVE, we are focused on the most pressing issues in modern aquaculture, including advancing our knowledge and science on operation and technologies. This innovative feedline will allow hatcheries to produce high-quality marine fish juveniles while taking quality and production standards to the next level.”

Breaking new ground in marine fish aquaculture

INVE´s multidisciplinary market-led approach, combining science, technology and innovation has led to the development of a nutritionally balanced, palatable larvae feed. It is efficiently assimilated by developing larvae, resulting in increased survival and performance.

These innovative formulas result from a thorough ingredient selection, which targets optimal nutrient assimilation and palatability from mouth opening until post-weaning. Moreover, the ingredients and the innovative manufacturing processes result in exceptional water behavior and stable particles, ultimately preventing nutrient leaching. This consequently helps maintain optimal water quality, a critical factor in marine fish hatchery, as poor quality water affect larval development, health status, and growth. Further explained by Steven Debono:

“Natura pRo and ExL are applied by an innovative but simple protocol. This protocol unites proper ingredient selection and manufacturing and operational ease, mimicking live rotifers under commercial conditions. The Natura pRo and ExL protocol is a rare combination of quality and convenience”. “Our protocol’s positive aspects include simplicity of use and boosting fry quality survival and predictability”.


Giulia Franchi, R&D Officer says:

“The application protocol represents an important step forward in hatchery management since it’s easy to integrate in the day-to-day activities of marine fish larval rearing”. “This was only possible to achieve through working side-by-side with our customers and our dedicated R&D facility (IARC), addressing real-life, daily challenges and concerns during product development. Farmers from different hatcheries worked with us closely. Our products are therefore developed and tested generally under commercial conditions and distinct contexts”, she continues.

This ground-breaking product was launched during Aquaculture Europe 2021 in Madeira. The reactions from the scientific audience and clients were extremely positive. Giulia Franchi provided a scientific presentation illustrating an innovative protocol, targeting Mediterranean larval rearing with Natura pRo and ExL. during the hatchery technology session at the scientific conference of the EAS.

“It is amazing to see how well this revolutionary protocol works. I’m very proud to be part of the group that made this happen” states Giulia.
