Fishery Profile

Fishery Overview

Grand Isle 9 Offshore Reef offshore fishery

Grand Isle 9 is a named Louisiana offshore reef, a reefed former sulfur-mine complex rather than the Grand Isle barrier island or an active production platform. Red snapper, greater amberjack, and king mackerel hold on that structure. It is a different fishery from Venice and the Mississippi Canyon. Do not board platforms. Coast Guard safety zones around active structures still apply. The reef is not a no-take area.
