Conger

The conger is also called a sea eel. Contrary to true eel, congers only live in sea water. They can reach up to three meters in length. Divers usually only see their head because they are often hiding between stones or in ship wrecks. It's not a good idea to pat a conger. They have very sharp teeth. There are stories of scuba divers that were swept for several meters by raging congers.

  • Maturity

    The larva stage for congers lasts one to two years. During this time, the transparent larvae live in all water layers except just above the sea floor. The sea currents can carry them over large distances. The larvae are then totally transparent; you can look right through them. They only get a color later on.

  • Fisheries

    Congers are not commercially interesting for fishermen. Nevertheless, one is sometimes caught and sold. They are much more popular among sport fishermen and divers with harpoons because they are large and can defend themselves bravely.

  • Distribution of conger
    Distribution of congers, Ecomare

    Congers live particularly along rocky coasts. Other places with lots of hiding places, such as wrecks, are also popular. They are found along the coasts of the northern Atlantic Ocean, the North Sea and the Baltic Sea. Every once in awhile, they are also found along the Dutch coast. Normally speaking, they don't live deeper than 500 meters. However, they spawn at depths between 3000 and 4000 meters.
