INICIO Plus S: A Strong Start Makes All the Difference

When fry absorb the yolk sac, a brief but decisive stage begins: first feeding. It is the first time they ingest exogenous feed, at a point when their digestive and immune system are still developing. The nutritional conditions provided at this stage play an important role in supporting early development and contributing to consistent performance throughout the production cycle.

At BioMar, we believe that this starting point should take place under the best possible nutritional conditions. To achieve this, first-feeding diets must be carefully formulated to support normal development and growth from the very beginning. Balanced nutrition at this stage contributes to the provision of essential nutrients needed for skeletal development and overall robustness, while supporting normal physiological processes.

A balanced diet also plays an important role in supporting digestive function. Carefully selected raw materials and nutrient profiles contribute to efficient feed utilization during this sensitive early life stage.

To achieve this, our first-feeding diets are formulated using high-quality raw materials, selected for their palatability, digestibility, and nutritional value. In addition to nutritional composition, the physical quality of the pellets is an important factor in maintaining good rearing conditions. Well-designed pellets help reduce the build-up of uneaten feed and organic matter in the system, supporting good water quality, tank hygiene, and fish welfare.

Pellet characteristics such as surface tension and sinking speed also influence feeding behavior. These parameters are designed to encourage synchronous feeding activity and support uniform access to feed across the population, contributing to more consistent early growth.

Salmon hatchery

INICIO Plus S is BioMar’s premium extruded starter feed, developed to support early fry development from the very first feeding. Built on BioMar’s technical expertise and experience, and validated under commercial production conditions worldwide, it provides hatcheries—whether flow‑through or RAS—with a reliable nutritional solution from day one.

Formulated with carefully selected, highly digestible raw materials, a balanced vitamin and mineral profile and added nucleotides, INICIO Plus S provides essential nutrients that contribute to normal cellular function and early growth. It also contains Bactocell®, the only probiotic registered for use in aquaculture feeds in the European Union, which supports a balanced intestinal microbiota.

Although first feeding represents only a short phase in the salmon life cycle, it plays an important role in establishing a strong nutritional foundation for subsequent development and production stages.
