Covering your trout’s needs

A strong focus on feed performance and the total economic performance of fish farming has over the last 50 years made BioMar the preferred choice for trout farmers all over Europe. As the leading expert on trout nutrition, we use our knowledge of nutrition, retention, and digestibility of raw material components to produce our high quality feed. BioMar's complete trout feed programme provides feed with high nutritional value, good physical quality, and the right pellet sizes designed to meet the fish needs in all life stages and in different farming conditions.

Starter Feeds

The optimal start

BioMar's INICIO Plus and INICIO feed ranges cover all the nutritional needs of farmed fish during the first life stages. Our ranges are based on superior quality raw materials, contain high protein levels, balanced amino-acid, and fatty acid profiles, vitamins and micronutrients.

Due to its specially developed composition, INICIO Plus consistently out-performs in feed trials with excellent feed conversion, growth, and low mortality results. By improving the performance of the fish, BioMar's starter feed contributes to increased production profitability.

Furthermore, a unique production process ensures an optimal sinking speed, well adapted to the eating behaviour of the fry. The result is an optimal growth rate and good feed conversion.

Grower Feeds


BioMar grower feeds of different digestible energy levels are available to farmers to provide flexibility in production and financial objectives. Determining which digestible energy level is optimal for a given farmer will depend on the farming intensity as well as the production setup and scope.

Increasing digestible energy (DE) in the feed improves the feed conversion rate (FCR) under the condition that the feed includes the corresponding digestible protein (DP) and the optimal essential amino acid levels needed for growth.  Farmers using feeds with higher digestible energy and can potentially use less feed for a given biomass produced. To achieve this goal, a fine tuning of the feed management is also required.

Broodstock Feeds


BioMar’s broodstock feed is specially formulated to provide key nutrients that will be transferred from the mother’s diet to the egg reserves stored in the yolk. EFICO Genio feed supports production of nutrient-rich eggs which hatch into high performing fry. In addition, EFICO Genio contains Bactocell®* and other immune-modulating ingredients which promote good condition of the broodstock to increase success of future egg production.

* Bactocell® is the only probiotic approved by the European Food Safety Authorities for inclusion in fish feed. The approval is based on extensive documentation of reduced occurrence of deformities across fish species.
