    Geographical Distribution

    Eastern North Atlantic northward to Norway, also Mediterranean and western Black Sea. Elsewhere, southward to Senegal, including the Canary Islands, Azores and Madeira.
    Habitat and Biology
    Benthic on the shelf on rocky or sandy bottoms at0-500 m.Many young, small fish can be caught in deep shore pools, particularly those with dense algal cover low down the shore. In soft-bottomed areas few congers are found, but they quickly colonize sunken wrecks, harbour walls, and loose stone groynes, and many can be caught in such man-made habitats.The conger's food consists of a wide range of mainly bottom-living fishes, large crustaceans, especially crabs, and octopuses.
    Sexual maturity at 5-15 years old; spawning in summer, 3-8 million eggs per individual.  Males generally mature at about 50-75 cm. Females at about 2 m.
    Size
    A maximum length of 3 m and a weight of 65 kg is attained; common from 60 to 150 cm. Males usually smaller than females.
    Interest to Fisheries
    Caught with bottom trawl, hooks and lines gear. The total catch reported for this species to FAO for 1999 was 16 170 t. The countries with the largest catches were France (4 412 t) and Spain (4 029 t).
    Marketed fresh and frozen. Eaten fried and baked.
