By attaining ASC certification, Gloria Maris Côte d’Opale joins a global community of producers dedicated to driving positive change in seafood farming. The achievement also increases the availability of farmed seafood in France that meets ASC’s environmental and social requirements.

As a pioneer, Gloria Maris Côte d’Opale is leading the way and demonstrating that a transparent, and responsible French aquaculture sector can meet the highest environmental and social standards.”

Bastien Riera, Deputy Chief Executive Officer of the Gloria Maris Group, said, “Achieving ASC certification is an important recognition of the work carried out by our teams over many years. This certification reflects our commitment to contributing to the development of a responsible, transparent, and demanding French aquaculture sector.”

A longstanding commitment to environmental preservation and social responsibility

Located along the beaches of the Hauts-de-France region, Gloria Maris Côte d’Opale has been farming sea bass and seabream for more than 40 years. This certification recognises the site’s long-standing commitment to responsible aquaculture, combining product quality, environmental preservation, and social responsibility.

Due to its location, the farm benefits from favorable conditions to farming of seabass and seabream. The site builds on expertise developed by Gloria Maris Côte d’Opale’s teams since 1982, with a strong focus on farming management and the continuous improvement of practices.

Fish produced at the site are supplied to foodservice professionals, fishmongers, and premium retail markets, with particular attention paid to product quality and traceability.
