Trust and consistency for sustainable aquaculture
“We’re improving the efficiency of marine proteins and using less resources to grow more healthy fish and shrimp. We believe our products are part of the solution to decrease the global aquaculture footprint”

iana Aqua, worldwide leader in the manufacturer of natural and sustainable ingredients for aquaculture, hosted a series of seminars on March 12th in Bangkok, on the occasion of VIV Asia 2019. The event, entitled “PEPTI’DAY – Trust and Consistency for Sustainable Aquaculture”, gathered more than 100 people, including renowned scientists and aqua feed mill professionals from all over Southeast Asia. Diana Aqua has been developing, for more than 15 years, very advanced solutions based on peptides production and understanding. The event aimed to provide insights and share expertise on “The Peptides concept”, the DNA of Diana Aqua. During the first presentation ‘Adding Value to Aquafeed: A Success Story’, Dr Fabio Soller, Diana Aqua ASPAC Technical Director, talked about how challenges and adversities on a personal life story and a Diana Aqua collaboration story were overcome for successful and fruitful partnerships among managers/employees, and companies for a win-win solution. “Every person and company want to utilise their full potential and be the best they can be. But the road to reach this goal is full of hard work, self-evaluation, relationships assessment, and openness to new ideas. Collaborating with different people or companies typically is the best route to success”, Dr Fabio said. The second topic was about Protein hydrolysates, shown to be nutritious feed ingredients and aid in fish meal replacement in aquafeed with beneficial biological effects when fed as part of formulated diets, e.g. improved growth performance, feed utilisation and non-specific immune response. Diana Aqua protein hydrolysates generally have well-balanced

Dr Bundit Yuangsoi, Assistant Professor at Khon Kaen University, presented a study conducted in indoor and outdoor systems to investigate ‘The effects of different types of protein hydrolysates in different culture system on growth performance, feed utilisation and immune response of Snakehead fish (Channa striatus)’. The results of indoor phase and outdoor phase trials indicated that growth performance of fish revealed that gross weight was significantly increased with fish fed diet with Diana Aqua protein hydrolysate. Hematological parameters were similar among treatments, but serum lysozyme and myeloperoxidase levels increased significantly for fish fed protein hydrolysate. Overall, the study indicated that diet inclusion of the Diana Aqua protein hydrolysates could improve growth performance and enhance non-specific host defense mechanisms for Snakehead fish. Then, Dr Vincent Fournier, R&D Manager at Diana Aqua, shared his expertise on ‘Protein Hydrolysates Benefits and Mechanisms of Actions in Fish and Shrimp Feed’, demonstrating that, for many years, protein hydrolysates have confirmed their potential to improve fish, shrimp and feed performances. Diana Aqua has communicated (through peer-review publications, articles in specialised journal, conferences) on many results of trials conducted in fish and shrimp to make the proof of concept of protein hydrolysates. “It is today well established that the production of protein hydrolysate requires high expertise in hydrolysis processes and very specific analytical capabilities to guarantee high levels of standardisation as well as consistent hydrolysate peptide profiles and resulting performances in fish and shrimp”, said Dr Vincent Fournier during the conference. Understanding the mechanisms of actions of protein hydrolysates is also a very important question to address in order to better characterise the benefits of such functional ingredients. For the last five years, Diana Aqua has conducted a lot of research to understand how dietary protein hydrolysates modulate the animal metabolism.
