112,997-acre Gulf St Vincent. Sector 14 Australian saltwater fishing map showing only directly measured AusBathyTopo 2026 cells, source-qualified fishing spots, official regional fish evidence, seasonal forage context, access guidance and current-rule links. Sector 14 trip-scale surveyed footprint within Gulf St Vincent. The Adelaide gulf from its northern flats through central channels to Kangaroo Island-facing entrances. The displayed footprint is not a legal boundary or a claim of complete named-water coverage. The water tops out around 111 ft. The depth chart comes from Geoscience Australia / AusSeabed bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 113,008 acres wrapped in 59.9 miles of bank. Its 1.3 shoreline index means few bank features; the contours below do the pattern work. Roughly 2% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 17.9 mi end to end and 13.3 mi across at its widest. If the bite dies, Spencer Gulf - Sector 84 is 8 mi to the north.
Regional occurrence does not mean equal abundance, child-specific catch rate, retention permission or a promised catch. Live state, territory, Commonwealth, protected-area and local rules always control. The roster may combine exact-water monitoring with habitat-filtered official regional evidence; it does not imply that every species is equally abundant throughout the mapped section.

Spring puts australian salmon in skinny water — 4 to 30 ft is the zone. Warm water sends them out to 14 to 80 ft; cold water stacks them in 4 to 30 ft. Sharp break is the standout, a drop-off at roughly 43 ft, rated prime for summer australian salmon. Plan around early morning and the evening in the warm months.

No facility from the cited South Australian boat ramps and marine facilities source was spatially attached within 3 km of this directly measured map footprint during the 2026-09-08 audit. This is an evidence gap, not a claim that public access is absent.

Private land and private launches need the owner's permission — please ask first.
Season dates, license requirements, and size and bag limits for South Australia waters are set by the PIRSA (current recreational species limits) — and special regulations can apply to Gulf St Vincent - Sector 14 specifically, so confirm the current rules before you fish. Check PIRSA's live species lookup, closures and SA Fishing app before every trip. Snapper remains absent from these page rosters because the current management closure prohibits targeting and catch-and-release in the affected South Australian waters through the stated closure period. Verify all size, boat and possession limits, protected areas, gear controls and local access directions. A contour, spot or access lead never grants fishing, retention, entry, parking or launching permission.
