The grouper, also known as Zackenbarsch in Germany, is a reef fish found worldwide in tropical and subtropical waters. It lives, for example, in the Great Barrier Reef or the Indian Ocean – or in our grouper farm in Kiel, operated by our sister company Oceanloop. This large fish is known for its firm, white flesh with a mild, slightly sweet taste and is considered a true premium fish, especially in Asian cuisines.

How is the GOOD GROUPER farmed? The innovative aquaculture

The GOOD GROUPER is bred by our sister company Oceanloop in a land-based aquaculture facility in Kiel. In 2020, Oceanloop partnered with the Alfred Wegener Institute to explore the fundamental requirements of grouper farming. By researching, for example, what feed or stocking density is ideal for the fish, the foundation was laid for innovative, successful grouper breeding.

"The topic of feed is something we are particularly proud of, because – unlike other farms – we determine the formula and composition of the feed ourselves. Here, we naturally try to mainly use local resources for it." Dr. Bert Wecker – CTO Oceanloop


There are many reasons for farming fish and seafood – a crucial aspect being sustainability. Aquaculture helps reduce pressure on wild fish populations and counter the problem of overfishing. However, not all forms of fish farming are equal. That's why we deliberately focus on land-based aquaculture with modern recirculating aquaculture systems (RAS).

The reason: In these closed systems, water quality, feeding, and stocking density can be precisely controlled. This minimizes stress and disease risks for the animals and creates optimal conditions for healthy growth. At the same time, water consumption is reduced, environmental pollution is minimized, and the risk of farmed fish entering natural ecosystems and affecting wild populations is eliminated.

Another advantage lies in the quality of the final product. Controlled feeding allows the nutritional profile to be precisely managed, which positively impacts the taste, texture, and tenderness of the fish. This results in products that are not only more sustainable, but also of particularly high quality.

Through intensive research and planning, as well as extensive expertise and attention to detail, the farm provides ideal conditions for the fish: As grouper is a tropical species, the water temperature is maintained at 30 °C year-round. The self-developed, high-quality feed and the absence of antibiotics and pharmaceuticals also positively influence the farming conditions and, ultimately, the quality of the fish.

From high-tech aquaculture to the plates of Michelin-starred chefs and home cooks

What begins in our farm under optimal conditions ends as a culinary highlight on the plates of discerning gourmets. The grouper is internationally recognised as a true premium fish and is a real treat for food lovers. But what makes our grouper so extraordinary?

Frequently asked questions about the grouper

For inspiration, explore our collection of grouper recipes in our world of pleasure.

Is the GOOD GROUPER sustainable?

Yes. Our grouper is raised by our sister company Oceanloop in a land-based aquaculture facility in Kiel. The recirculating aquaculture system (RAS) significantly reduces water consumption, shortens transport routes and helps reduce pressure on wild fish populations, making it a more sustainable choice for seafood lovers.

Can I eat the GOOD GROUPER raw?

Yes. Our grouper is sashimi-grade and suitable for raw preparations such as sashimi, ceviche and crudo.

How are the fish harvested after they are caught?

The grouper is harvested using the traditional Japanese Ikejime method. Widely regarded as one of the most humane and quality-focused methods of fish harvesting, Ikejime minimises stress and helps preserve the exceptional texture and flavour of the fish.
