NEWS 24 FEED & ADDITIVE MAGAZINE August 2025 Set on 1,300 hectares of historic fish farming land, the Končanica Project in Croatia marks a significant step forward in circular bioeconomy, combining aquaculture, renewable energy, and insect farming into one integrated, self-sufficient system. The initiative is expected to respond to growing climate and market pressures, including rising water temperatures, declining yields, and lack of value-added infrastructure, by introducing a multi-layered model that aims to revitalize the region while setting a blueprint for sustainable production in Europe. At the heart of the project is a collaboration between three specialized partners: Flybox®, FreezeM, and Ribnjačarstvo Končanica, Croatia’s oldest carp farming operation, According to the announcement, Flybox® contributes its modular insect farming technology and operational expertise, enabling decentralized waste conversion and protein production close to the source. FreezeM supplies high-performance Black Soldier Fly (BSF) neonates using its PauseM® live-suspension technology, allowing rearing operations to be decoupled from breeding and seamlessly integrated into the aquaculture value chain. Ribnjačarstvo Končanica brings deep local knowledge and infrastructure, serving as the foundation for integrating modern H-RAS systems, fish processing, and energy capture from biogas and photovoltaics. Together, the partners are developing a replicable, closed-loop model where organic by-products are converted into live insect feed and natural fertilizers, reducing waste, increasing resilience, and diversifying revenue streams.

In Europe, 83% of poultry farms are thought to be infested, at an estimated cost of 360 million euros to the industry. To help livestock farmers deal with this scourge, CCPA Group stated that Deltavit is innovating with the Acari® program, a comprehensive approach combining effectiveness, naturalness and profitability – now enhanced by a new digital management tool: The Acaritool mobile application. The Acari® program is based on a dual strategy, combining effective natural solutions with customized digital support. According to the announcement, the Acaritool mobile application, developed to monitor farms, enables each farmer to: • Monitor changes in the level of infestation, • Precisely adapt the use of products to the situation in their buildings, • Secure their zootechnical and economic performance. Two complementary products form the basis of the program: • Acariflash, a plant- and aromatic-based complementary feed or water additive that supports laying performance in the presence of poultry red mites. Acariflash® UAB is also available for organic farms. • Acaritec, a drying agent in a powder form that can be used during downtime or in the presence of animals to maintain hygiene in your buildings. Acaritec can also be used on organic farms. Read more>> Deltavit’s Acaritool app targets poultry red mites Photo: CCPA Group
