Historically, feed choices were made using datasheets, recommendations, or experience, but this may not provide enough information for specific farm needs. Even similar feed types can perform differently, making trials essential for informed decisions.
At BioMar, we conduct benchmark trials to compare our feeds, both among themselves and against our competitors´ - in controlled environments as well as on commercial farms.
Conducting trials under controlled conditions
Trials should begin with a uniform group of fish (same strain and grade). To ensure a trial is valid, fish should ideally double their weight by the end of the trial period. The rearing units (cages, ponds, etc.) must be identical in size, shape, and water quality. If land-based, water should come from the same source; if sea-based, units should be exposed to the same current conditions.
To avoid bias, trial units with the same code should not be placed sequentially. A minimum of three units per trial code is necessary for reliable results.
Reliable results require at least three units (cages, ponds, channels, or tanks) per trial code. Using three or more units per trial code ensures that variations in the results are accounted for, providing a more accurate reflection of the trial's reliability.
Examples of trial layout. Color codes represent different trial codes. To the left a simple trial layout for a flow through farm where two feed types are being tested. To the right an example of trial layout for a cage farm testing five types of feed.
Accuracy and Documentation
Accurate data collection is critical to any trial’s success. Every observation must be meticulously recorded, and BioMar can assist with setting up proper registration systems on farms.
It’s especially important to record the weight of fish at the start and end of the trial, monitor daily feed consumption, and document any fish mortality. If any deviations from the original plan occur, maintaining accuracy is still crucial. The trial should not be stopped due to unexpected events; instead, document the changes and consult with BioMar to determine the next steps.
Minor differences, such as fish behavior (e.g., appetite and agitation), water quality, sediment presence, and faeces texture, should also be recorded. While some mistakes can be adjusted during the data analysis phase, this is only possible if detailed records are kept.
Registration practices
Each trial unit should have separate records, and data from different feed types should not be combined. Daily documentation should include:
Feed consumption
Number and weight of dead fish
Water temperature
Observations on weather, fish behavior, disease, and faeces
Choosing the Right Feeding Strategy
A well-designed feeding strategy should align with specific production goals to maximize performance.
During benchmark trials, we work closely with farmers to understand their objectives, whether it's faster growth, improved feed conversion, or enhanced sustainability. Based on these insights, we recommend bespoke, optimized feeding strategies tailored to their needs. By continuously monitoring and refining these strategies, we ensure long-term success and increased profitability for our partners.
BioFarm – BioMar’s Expert Advisory Team
BioMar’s technical advisory team, BioFarm, offers support in trial design and data analysis. Sharing trial results helps improve feed performance across farms. BioMar provides forms to document essential data, ensuring that trials are thorough and reliable.
Establishing Long-Term Collaboration with Farmers
Running benchmark trials with our customers creates a win-win situation for both parties. As a feed supplier, these trials allow us to evaluate the real-world performance of our feeds, ensuring continuous improvement and innovation. For our customers, participating in these trials provides firsthand involvement in our product development process while maximizing the value they receive from BioMar products.
We are always seeking to establish strong collaborations with our partners and identify suitable locations for benchmark trial, to the benefit of both parties through shared insights and improved performance.

At the BioMar factory in Denmark, we assist salmon and trout farmers with tailored solutions, backed by our technical expert team, BioFarm. These advisors are dedicated to sharing knowledge on pigmentation strategies, helping our partners achieve top-quality fish fillets.
After a harsh winter with low water temperatures, the approach of spring may be accompanied by a rapid rise in temperature, especially in some areas such as northern Europe. This period can be challenging and risky for the fish, especially if the feeding strategy is not adapted to these circumstances.
Their aquaculture journey began with curiosity sparked by an unused pond on his father’s land. With no prior experience in fish farming but a strong background in finance and business, Lauris Apsis saw an opportunity to create something meaningful. Recognizing sustainability as the key to long-term success, Lauris and his Finnish partner, Salmela-Yhtiot Oy founded Blue Circle (Zivs uz Ledus), a Latvian farm dedicated to producing premium Arctic char using cutting-edge recirculating aquaculture systems (RAS).
