The common octopus Octopus vulgaris (Cuvier, 1797) is the most important cephalopod in fisheries along the Moroccan Mediterranean coast. The purpose of this study is the fishery management of this species. The monthly landings are analyzed from 2008 to 2015. Data of DML by fishing gear are used to examine the catch composition. The results showed an inter-annual variability in landing. The highest catch rates were obtained from October to December, while during the rest of the year they remained at low levels. Clay pots exploited large individuals than trawlers. We conclude that the spawning period lasts from Spring to Summer where a recovery period should be applied.
