Alosa fallax, also known as twait shad, is a shad species native to Europe. Adults live in the sea and migrate to estuaries only for reproduction. Found in the Eastern temperate Atlantic, they face challenges from dams, pollution, and coastal overfishing. Juveniles gather in estuaries and feed near the shore.

The European eel, A. anguilla, is a freshwater fish native to Europe. Abundant until the 1980s, it has been severely affected by overfishing. It is considered a critically endangered species in France and several neighboring countries.

Gobio gobio is the most common species of gudgeon in Europe. It is a benthic fish that prefers clear waters with sandy and gravelly bottoms. During the day, it continuously sifts through the substrate in search of small invertebrates (insect larvae, crustaceans, oligochaetes, mollusks).

This fish is well known in our ponds. The reproduction in this species occurs from May to June, the females lay up to 200,000 eggs on vegetation near the banks. This fish can hybridize with many other species that breed at the same time as it (Roach, Bremen, Bleak ...).

The reproduction of the catfish occurs from June to August. The female lays about 60 000 large eggs in the vegetation, the male protects them for 10 days. Native to Eastern Europe, it was introduced in all major European rivers. In the Meuse, its size can exceed two meters long.
