lac - Discover fishes living in these biotopes

This small fish detects alarm substances emitted by previous preys of a pike. This allows it to determine whether the predator is fasting or not. Breeding occurs from May to July. This species is frequently used as live bait to catch big fish (pike, perch).

Altolamprologus calvus is endemic to the southwestern part of Lake Tanganyika. It differs from A. compressiceps with its more pointed head and elongated body. This carnivorous species is specialized in hunting small crustaceans, which it captures by sneaking into crevices and fissures.

It easily accommodates to life in captivity, but it is aggressive toward smaller species. It breeds easily in aquarium: the male delineates a territory in which the female lays its eggs. After hatching, the pair will protect juveniles against potential predators.

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.
