A study using 1,350, split into nine tanks, was conducted over an 83-day period by an independent research provider, Otter Ferry Seafish, located in Scotland, UK. L. bergylta were fed one of three dietary groups in triplicate; Control, T1 (Orego-Stim Forte at 1kg/t), and T2 (Orego-Stim Forte at 3.5kg/t). This trial concluded that dietary Orego-Stim Forte supplementation, at both concentrations, improved the specific growth rate (SGR) and feed conversion ratio (FCR) of L. bergylta (figure 3). The greatest SGR and FCR improvements were seen in the diet containing 3.5kg/t of Orego-Stim Forte, which is 13.2% and 10.7%, respectively, more advantageous compared to the control. CONCLUDING REMARKS With the significant growth trajectory of the aquaculture sector coupled with the ballooning human population, it is essential, now more than ever, to provide aquaculture producers with highly effective and sustainable solutions. Phytogenic feed additives have demonstrated their potential for improving the health and growth performance of aquaculture species whilst supporting antibiotic free production in the fight against antimicrobial resistance. The antioxidant, anti-inflammatory, immunomodulatory, antimicrobial, and growth promoting natural properties of Anpario’s Orego-Stim range, makes them highly-effective, yet sustainable solutions.

About Gerred Fuchs Gerred Fuchs joined Anpario at the beginning of this year as the Aqua Technical Sales Manager. As part of his role, Fuchs supports product development and strengthens technical support across Brazil and Egypt, in response to Anpario’s deepening focus within the aquaculture sector. Prior to his current role at Anpario, Fuchs completed a Master of Research focussing on aquaculture feed additives at the University of Portsmouth, following a BSc in Aquaculture and Fishery Management from University Centre Sparholt. Fuchs's previous industrial experiences include Aquatic Sales, Aquatic Technician for salmonid trials, and researching novel feed ingredients and additives to improve the health, diet utilisation, growth performance, and production sustainability of various aquaculture species.
