NEWS 18 FEED & ADDITIVE MAGAZINE June 2024 Global shrimp farmers face challenges with soaring costs and rampaging diseases that diminish their profits. Finnish biotech startup Enifer published a new study conducted by independent study partner AquaBioTech Group, at its aquaculture R&D facility, Innovia, about the health benefits of using Enifer’s PEKILO®Aqua mycoprotein in shrimp feed. The company unveiled that the results were excellent, with shrimp living longer and healthier when fed with PEKILO®Aqua. Currently, shrimp get roughly 10% of their protein from a fishmeal diet. Fishmeal, derived from marine fish, has been a staple in shrimp diets due to its rich protein content. Additionally, fishmeal contributes to the overall palatability of the diet. However, almost 90 percent of global marine fish stocks are now fully exploited or overfished, and the shrimp feed industry is the largest single user of fishmeal. According to the statement of Enifer, the study found that the overall mortality rate was notably reduced in shrimp fed the PEKILO®Aqua diet. The survival rate increased from 74% to 85% among shrimp consuming the 30% PEKILO®Aqua diet. Additionally, following carcass analysis, it was observed that the crude protein content was significantly higher (2.5%) in the PEKILO®Aqua-fed group compared to those fed diets containing higher levels of fishmeal. Shrimp have an innate immune system but no adaptive immune system, meaning they cannot be vaccinated. To make shrimp more resistant to diseases, their immune systems must be stimulated periodically or constantly with separately added compounds. Enifer points out that PEKILO®Aqua already includes immune-enhancing compounds like beta-glucan and nucleotides, which makes it a great feed for disease-prone shrimp as they can build immune cells faster without damaging the shrimp’s energy reserves. The results also showed that PEKILO®Aqua contributes to improved shrimp growth without an increase in feed intake. Additionally, in addition to nucleotides, PEKILO®Aqua contains another shrimp growth-enhancing compound, spermine.

The submission leading to this authorization was initiated by Kemin Nutrisurance, the pet food and rendering technologies business unit of Kemin Industries, and the resulting regulation was published in the Official Journal of the European Union on April 15. The Commission Implementing Regulation (EU) 2024/1068 categorizes and approves of the additive as a "technological additive" within the "antioxidants" functional group, effective May 5. Before this approval, the European Union's pet food market primarily consisted of tocopherols for antioxidants, with limited options for antioxidant molecules of natural origin. This new addition of rosemary extracts not only expands the range of available antioxidants but also addresses critical supply chain challenges.
