Fishery Profile
Fishery Overview
Grand Isle fishery
A Louisiana barrier-island shore and pass fishery pinned at Grand Isle, not Venice and not Pontchartrain. LDWF treats this coast as a red drum, spotted seatrout, sheepshead, southern flounder, Spanish mackerel, cobia, and tarpon destination. Cobia and tarpon remain seasonal targets without automatic cards.
Fishery type
Barrier island pass
Fishing modes
Shore
Inshore boat
Habitat and structure

Fishery Targets
Red drum, spotted seatrout, sheepshead, and southern flounder are documented Grand Isle targets. This profile does not encode month windows for those species because accepted evidence is occurrence-level. Spanish mackerel have an accepted approximate Spring — Fall card. Cobia and tarpon may be seasonal targets without accepted cards. Do not copy Texas flounder October–December windows.

Access, Safety and Regulations
Access
Public beach, jetty, and nearby pass access at Grand Isle. Confirm current LDWF, parish, and park postings. This pin is Grand Isle, not Venice and not Pontchartrain.
Primary hazards
Pass current, heat, and thunderstorms are the primary hazards. Do not treat Venice ferry or South Pass as this destination's access.
Fishery considerations
Tide and live water level are NOAA 8761724 Grand Isle NWLON, at-location. This profile does not score currents or change the coastal rating.
Island and pass wind can steepen the surface against tide. Waves are intentionally unsupported. This is not a Venice river-mouth forecast.
Regulations
Size limits, seasons, and possession rules change. Verify the current official regulations before fishing.
The map marker represents the cataloged waterbody or monitoring location and may not indicate legal parking or public access. Confirm access through the official information before visiting.
Coastal conditions can vary over short distances. Predictions and remote observations are planning information, not guarantees of access or safety.
Pin is Grand Isle, Jefferson Parish. Not Venice / South Pass and not Pontchartrain.
NOAA 8761724 Grand Isle is live NWLON at-location. Trip family reuses GULF_INLET_PASS; do not invent a barrier-island family.
Current Coastal Rating is a provisional public-Beta rating. The regional methodology is still calibrating and is not formally accepted. The verdict is capped at Consider while calibration and evidence remain limited. Coastal Estimated is unauthorized.
