Choosing the right feed

Best Economic Performance


BioMar wants to be the best partner in terms of increasing the financial yield of our customers. By means of adapted feed composition, feed choice and feeding regime, we can offer a unique support system based on documentation beyond comparison; the Best Economic Performance model.

The customer defines the performance goals; BioMar adapts the product strategy to fit the customer’s demands. The prices of feed raw materials and also farmed fish fluctuate for many reasons, including global economy, climate, growth conditions, market development etc. When both costs and income fluctuate, it is crucial that the fish farmer can choose products that provide the best financial end result – tailored to meet the circumstances.

Feeding at all stages


BioMar's BioMar's feed range covers special needs throughout the life cycle from egg to harvest for both freshwater and saltwater fish species as well as shrimp.

In addition to LARVIVA feed for hatcheries and a number of specific types of fry feed, we offer a wide range of transfer feed and wax feed developed to meet the nutritional needs of specific species under different breeding conditions. Furthermore, we offer specially enriched breeding feed, which means that mother fish can deliver eggs of the highest quality and thereby ensure the best possible start to a new cycle.

Fish Health


We care about the health of fish, fish farmer’s finances and the healthy reputation that farmed fish deserve and on which the industry relies.

BioMar aims to offer a range of functional diets effective against the most serious production disorders, and covering the entire production cycle for a large number of farmed species.

Our research on one species is very often relevant for another. This is especially applicable in terms of fish health, where functional diets tend to have a broader spectrum of use with respect to species than grower feeds do.


Based on field experience, research data and supported by programs with calculation models, BioFarms provides the team of technical advisors with guidance on relevant nutrition and feeding strategies.

In the past, the profitability of aquaculture used to be limited by whether the growth potential of a given farmed species could be exploited via the feed. Today, our feed is optimised to potentially deliver a feed yield that can take full advantage of this potential.

Until a few years ago, it was not common that cleaner fish in cages were fed maintenance feeds. This practice has now changed however as research has identified that insufficient access to the correct nutrients makes for less healthy and less functional cleaner fish.

Wild-caught wrasse

There are six species of wrasse living in Norwegian waters. Goldsinny and corkwing are the most common. There are smaller numbers of ballan wrasse, rock cook wrasse, scale-rayed wrasse and cuckoo wrasse.

Why cleaner fish?

The salmon louse is the most common parasite on farmed salmon, and one of the biggest challenges for the aquaculture industry. Cleaner fish, which from nature's perspective are designed to feed on such parasites, are used in the cages to feed on lice from farmed fish.

What are salmon lice?

The greatest health challenge for the fish farming industry today is infection with the parasite Lepeophtheirus salmonis, better known as the salmon louse.

Endurance tests in “The Flume”

To test the influence of feed on cardiovascular capacity and simultaneously examine the role of phospholipids, four test diets were used. Two contained high levels of EPA and DHA, and two had low levels. One of the levels contained krill oil – a source of fatty acids – and the other fish oil. The feed was administered over a period of 8 weeks before samples were taken and measurement of cardiac performance was made in "The Flume".

Results from field trials undertaken during 2013 and 2014

The trial in 2013 was a commercial trial with a customer in Central Norway with v12G, where two sets of two cages were compared with respect to origin and disease history. The trial in 2014 was carried out on a group of fish in southern Norway without significant disease problems during the trial period.

HSMI infection experiments at VESO Vikan

Pre-smolt received trial diets for 8 weeks in freshwater before being transferred to the sea. The infection was introduced directly after their transfer to seawater. To simulate a natural transmission of infection, infectious “Trojans” were used.

Systematic assemblage of documentation

In the research department at BioMar, we wanted to investigate whether the positive health effects also yield measurable effects on the ability to combat disease in salmon and for this reason we have carried out a series of studies focusing on cardiac health.
