31,161-acre Béziers and Agde Coast. South Central France saltwater fishing map with official SHOM 100 m bathymetry, source-qualified fishing spots, official regional fish evidence, seasonal forage guidance, public shore-use context and current-rule links. The coast around the Orb, Cap d’Agde and Hérault mouths, with volcanic rock, jetties, beaches and offshore breaks. This page covers the south central angler-scale survey window. The water tops out around 185 ft. The depth chart comes from Shom (Service hydrographique et océanographique de la Marine) bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here's the year, species by species, as the scoring engine sees it.
Béziers and Agde Coast - South Central maps at 31,130 acres behind 31 miles of shoreline. Nearly circular (index 1.3), so the story is the bottom, not the bank. Roughly 4% of the water is 15 ft or less, the band where the food chain lives. Tip to tip the water measures near 11.2 mi with a 6.5-mi widest point. Its nearest charted neighbour, Narbonne and Gruissan Coast - North East, is 6 mi to the west.

Regional occurrence supports a search target, not equal abundance, child-specific catch rate, retention permission or a promised catch. Current national, EU, regional, protected-area and species 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.

Early season european seabass use the shallows, holding in 3 to 25 ft. Expect a summer slide to 2 to 30 ft, then a winter hold in 10 to 55 ft. Put Shoreline point first on the milk run — a point near 10 ft that grades good for fall. In summer the feeding windows fall in early morning and the evening. Tie on a surface lure or a paddle-tail soft plastic and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Shoreline point (10 ft) | Paddle-tail soft plastic, Shallow minnow plug |
| Summer | 2 to 30 ft | dawn & dusk | Shoreline point (10 ft) | Surface lure, Paddle-tail soft plastic |
| Fall | 4 to 40 ft | dawn & dusk | Shoreline point (10 ft) | Slim metal lure, Minnow plug |
| Winter | 10 to 55 ft | midday | open water | Slow soft-plastic shad, Suspending minnow |
Start shallow in spring: common sole sit in 6 to 30 ft that time of year. They don't go far with the seasons — 3 to 30 ft covers summer, 20 to 70 ft covers winter. Top water on the chart: SHOM-grid flat, a feeding flat in the 19 ft range, prime in spring. Fish it in the evening and you'll meet the bite. Throw a light rolling-lead rig until the fish tell you otherwise.

Access data: European Environment Agency — 2025 Bathing Water Directive Sites (France). Confirm conditions and fees locally before you launch.
Season dates, license requirements, and size and bag limits for France waters are set by the Légifrance (current French recreational sea-fishing minimum sizes) — and special regulations can apply to Béziers and Agde Coast - South Central specifically, so confirm the current rules before you fish. French recreational sea-fishing rules combine current national and European species measures with façade, prefectural, marine-protected-area, harbour and local access controls. Check live minimum sizes, quotas, seasonal or method closures, marking requirements and any no-take zone before every trip. A SHOM contour, fishing-spot marker or designated bathing-water lead is planning context only and never permission to fish, retain a catch, park, launch or enter restricted shore or port property.
