Understanding aquaculture
- What is aquaculture?
Aquaculture is the farming of fish, shellfish and other aquatic organisms in a controlled environment. It can take place at sea, in lagoons or in tanks, and involves supporting the growth of species from birth through to sale.
Unlike wild fishing, which depends on available natural resources, aquaculture allows production to be controlled and ensures a steady supply of seafood.
Today, it accounts for a significant share of the world’s food supply and plays a key role in the future of marine resources.
2. What is the difference between farmed and wild-caught fish?
Wild-caught fish depend on the unpredictability of fishing and the resources available in the sea. Farmed fish, when produced under good conditions, offer:
- consistent quality
- full traceability
- a steady supply
- a carefully managed impact on natural resources
At Gloria Maris, our products are often indistinguishable from wild-caught fish during
blind tastings by chefs.
3. Can farmed fish be premium quality?
Yes, absolutely, provided it meets strict criteria.
At Gloria Maris, our premium positioning is built on:
- low stocking density
- controlled feedingpreserved natural environmentsstringent certifications
This level of excellence is what brings our fish to fine-dining tables and events such as the Bocuse d’Or.
4. How do you ensure farmed fish tastes great?
Taste quality depends on several factors:
- water quality
- space available to the fish
- feed
- stress (or lack thereof)
At Gloria Maris, these parameters are carefully controlled at every stage of the value chain, from the hatchery to delivery.
Labels & Certifications
5. What is the Label Rouge certification in aquaculture?
The Label Rouge is an official French quality mark guaranteeing superior quality.
It requires:
low stocking density
certified feed
taste quality approved by expert panels
At Gloria Maris, several species, including meagre and sea bream, carry this demanding quality mark.
6. What’s the difference between Label Rouge and organic?
These labels serve different purposes:
- Label Rouge: superior eating quality
- Organic: strict environmental standards and no antibiotics
We combine these approaches across our sites to ensure quality, sustainability and traceability.
7. What does “Origine France Garantie” mean for fish?
This certification guarantees that the fish is raised and processed entirely in France. This is a key criterion for:
- transparency
- food sovereignty
- reduced transportation
It is particularly applied to products from the Opal Coast.
8. Can your fish be traced?
Yes, every fish can be traced from the hatchery to the end customer. This traceability ensures:
- food security
- transparency
- consistent quality
Sustainability & Environment
9. Is aquaculture sustainable?
When done well, yes. Aquaculture helps:
- limiting overfishing
- secure the food supply
- reduce pressure on wild ecosystems
At Gloria Maris, we put practical measures in place: sites in Natura 2000 areas, energy efficiency improvements, and antibiotic-free organic farming.
10. How does Gloria Maris reduce its environmental impact?
We work on several levels:
- carefully selected, pristine sites
- optimised resource management
- innovation (e.g. industrial heat recovery)
- alternative feed (algae, insects, in R&D)
Our goal is to produce better, with less impact.
11. Do you use antibiotics?
In European aquaculture, the preventive use of antibiotics is strictly prohibited: medication is only used in the event of a diagnosed illness, and always prescribed by a veterinarian following a diagnosis.
At our scale, we have chosen to be uncompromising: no treatments whatsoever.
Our priority is prevention: water quality, low stocking densities, a healthy diet and vaccinating fish when recommended, to prevent disease.
We do not administer any antibiotic or antiparasitic treatments to our fish, as these preventive care methods mean they are not needed. This is a real success, and we are held up as an example of best practice throughout the Mediterranean!
