Paradigm shift on the plate

The WWF (World Wide Fund for Nature) organization proposes an unusual but pragmatic solution to protect marine ecosystems in Greece: the consumption of invasive fish. WWF representatives point out that, especially in southern Greece and the Dodecanese archipelago, non-native species are becoming increasingly present on the market. Instead of being discarded, as was often the case until now, these species could become a valuable food resource. "There is a new reality on the market,” explain the specialists, emphasizing that the appearance of these species is no longer a marginal phenomenon, but one that is constantly growing.

• Why invasive species are a problem

Invasive species disrupt the natural balance of marine ecosystems, competing with local fauna for food and habitat. In some cases, they can drastically reduce native fish populations or affect biodiversity. To combat this phenomenon, WWF suggests a simple approach: integrating these species into current consumption. This reduces the pressure on the ecosystem and fishermen can make use of catches that would otherwise be wasted.

The new guide published by WWF includes over 100 species of fish and seafood available on the Greek market, of which 13 are newly added invasive species. These include: brown shrimp (Penaeus aztecus), native to the Atlantic; blue crab (Callinectes sapidus); lionfish (Pterois miles), known for its rapid spread in the Mediterranean Sea.

• An opportunity for fishermen and consumers

Until recently, many fishermen threw these catches back into the sea due to lack of demand. However, experts point out that most of these species are perfectly edible and even appreciated in other parts of the world. By changing consumer preferences, this "ecological problem” could become an economic opportunity, reducing waste and helping to protect marine biodiversity.

The WWF initiative reflects an increasingly visible trend: the adaptation of human behavior to new ecological realities. In a context in which climate change and globalization affect ecosystems, solutions can sometimes come from simple gestures - including the choices made at the table.
