farm in the Atlantic Ocean.


Located in the Biomarine Center in Nazaré.

Replicates the ideal conditions found in nature where clams reproduce according to their biological inclination and grow until they reach the seed stage. It benefits from direct access to the high-quality waters of Nazaré, with continuous renewal even near the coast.


Research and Development (R&D)

We develop R&D projects in the fields of cultivation, genetics, and pathology. We apply a scientific program of selective breeding for the species Ruditapes decussatus. We work in collaboration with various universities, research centers, and other external partners in innovation.


Broodstock Room

The life cycle begins in this room where breeders from various sources, including from our own open sea farm, spawn in the water in large quantities.


Larvary room

This phase is critical and requires thorough control to assist in the transformation from larvae to seed. The metamorphosis includes the formation of the shell, siphons, and foot.


Seeds room

The clams grow in the hatchery under controlled and high-quality conditions. By cultivating them through a continuous process, we are able to send out seed throughout the year.



The clams are exclusively fed with phytoplankton. We cultivate various species in our facilities, thus improving the diets of our clams.


Located in the Atlantic Ocean, Algarve

Our open sea farm is the first in the world to cultivate clams. Located in the Atlantic Ocean, 3.5 nautical miles off the coast of Lagos in the Algarve and it covers 100 hectares, allowing for grow-out and harvesting throughout the year.


Clams from the open sea

The high-quality waters in our open sea farm have an official "Class A" rating by IPMA. It benefits from ideal conditions such as mild temperatures, abundant food supply, and constant water renewal, which contribute to the growth of high-quality open-sea clams.


Vertical farming with
suspended lanterns

We suspend lanterns along the longlines, creating a shelter for our clams to grow naturally submerged in the Atlantic Ocean.


Phytoplankton natural food

The clams feed exclusively on naturally abundant phytoplankton in the open sea, due to upwelling. In contrast to other sources of protein, in bivalve aquaculture, we do not use inputs such as feed or antibiotics.


Farming activities

The team carries out various activities on land and at sea, where "boats are our tractors." Grading and biofouling control activities are critical to enable the natural growth of clams.


Continuous farming

We can sow, cultivate, and harvest all year round. The clams continue to grow even after reaching the minimum commercial size.

Clam Life Cycle

From spawning to adulthood.

The life cycle begins in the hatchery in Nazaré.
The first step is the conditioning and spawning of the breeders.
The second step is larval cultivation until metamorphosis.
The third step is seed cultivation in the hatchery and in the nursery.

After a few months, the seed is transferred to the open sea farm on the coast of Algarve to continue its growth. The seed then spends most of its life growing in the open sea until it reaches the minimum commercial size, which depends on seasonality and environmental and cultivation conditions.
