The nets used in this fishery are vertical, static monofilament or trifilament gear, anchored to the sea floor. Fish are caught around the gills by the gill net or get entangled.

Gilthead sea bream and sea bass fisheries operate in the coastal areas of Languedoc-Roussillon and PACA, both offshore and near shore. In both regions, the fleet is mainly made up of gillnetters.

Use of the different kinds of nets is dependent on the fisherman’s experience, the species aimed for, the season, physical factors and familiarity with the stock area.
