Advancing sustainable clam production: new research strengthens bivalve aquaculture innovation

Oceano Fresco continues to actively contribute to the development of sustainable aquaculture in Portugal, participating in new scientific research focused on improving clam production under controlled conditions.

This study focuses on two economically important species — Ruditapes decussatus and Venerupis corrugata — and explores ways to optimize one of the most critical stages of their life cycle: larval metamorphosis.

In bivalve aquaculture, this stage represents a major bottleneck, often associated with high mortality and inconsistent development. Improving this process is key to increasing hatchery efficiency and ensuring a reliable and sustainable seed supply.

The research evaluates the effect of chemical cues such as epinephrine and GABA in inducing metamorphosis, demonstrating that small variations in concentration and exposure time can significantly impact both development success and survival.

The findings highlight the importance of species-specific approaches, as well as the need to consider not only immediate effects but also post-exposure outcomes, which are critical for ensuring juvenile viability.

These insights contribute to a more efficient and predictable production of clams, reinforcing the role of scientific innovation in advancing aquaculture and the blue economy.

At Oceano Fresco, we believe that combining science, technology, and sustainability is essential to address global food challenges and unlock the potential of marine resources.
