11,483-acre Pertuis Breton. South East 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 northern Pertuis between the mainland and Île de Ré, with shallow banks, channels and estuary influence. This page covers the south east angler-scale survey window. The water tops out around 36 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. Every species below gets its seasonal read from the same numbers driving the chart.
Pertuis Breton - South East maps at 11,480 acres behind 34.2 miles of shoreline. With a shoreline index of 2.3, this water is all arms and coves — edge habitat well beyond its acreage. 66% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Tip to tip the water measures near 14.2 mi with a 4.5-mi widest point. Its nearest charted neighbour, Pertuis Breton - South Central, is 8 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.

Spring european seabass on Pertuis Breton - South East hold shallow, usually 3 to 25 ft. They move out to 2 to 30 ft in summer and finish the year down in 7 to 36 ft. Put SHOM-grid current seam first on the milk run — a current seam near 14 ft that grades prime for summer. The feeding windows run early morning and the evening. The summer box starts with a surface lure or a paddle-tail soft plastic.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | SHOM-grid current seam (14 ft) | Paddle-tail soft plastic, Shallow minnow plug |
| Summer | 2 to 30 ft | dawn & dusk | SHOM-grid current seam (14 ft) | Surface lure, Paddle-tail soft plastic |
| Fall | 4 to 36 ft | dawn & dusk | SHOM-grid current seam (14 ft) | Slim metal lure, Minnow plug |
| Winter | 7 to 36 ft | midday | Deepest basin (36 ft) | Slow soft-plastic shad, Suspending minnow |
The spring pattern is a shallow one: common sole in 6 to 30 ft. The depth story barely changes: 3 to 30 ft through summer, 10 to 36 ft in winter. Top water on the chart: SHOM-grid flat, a feeding flat in the 4 ft range, prime in summer. Time it for the evening. Summer baits: a light rolling-lead rig gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 6 to 30 ft | dusk | SHOM-grid channel edge (18 ft) | Tiny bottom jig |
| Summer | 3 to 30 ft | dusk | SHOM-grid flat (4 ft) | Light rolling-lead rig |
| Fall | 7 to 36 ft | dusk | SHOM-grid channel edge (18 ft) | Compact bottom jig |
| Winter | 10 to 36 ft | night | Deepest basin (36 ft) |
Spring puts european flounder in skinny water — 5 to 25 ft is the zone. Warm water sends them out to 6 to 35 ft; cold water stacks them in 11 to 36 ft. SHOM-grid flat is the standout, a feeding flat at roughly 4 ft, rated prime for spring european flounder. Plan around early morning and the evening in the warm months. A bottom jig with spinner blade covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dusk | SHOM-grid flat (4 ft) | Small bucktail dragged on bottom |
| Summer | 6 to 35 ft | dawn & dusk | SHOM-grid flat (4 ft) | Bottom jig with spinner blade |
| Fall | 7 to 36 ft | dusk | Sharp break (6 ft) | Compact bottom jig |
| Winter | 11 to 36 ft | midday | Deepest basin (36 ft) | Small bottom jig |
Come spring, look for european plaice tight to the bank in 8 to 35 ft. They move out to 5 to 36 ft in summer and finish the year down in 11 to 36 ft. If you only fish one area, make it SHOM-grid channel edge: a channel edge around 18 ft that scores prime in fall. Best bite is early morning and the evening. A light spooned bottom rig or a beaded trace is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 35 ft | dusk | SHOM-grid channel edge (18 ft) | Beaded flowing trace |
| Summer | 5 to 36 ft | dawn & dusk | SHOM-grid flat (4 ft) | Light spooned bottom rig, Beaded trace |
| Fall | 7 to 36 ft | dusk | SHOM-grid channel edge (18 ft) | Beaded bottom trace |
| Winter | 11 to 36 ft | midday | Deepest basin (36 ft) |
Come spring, look for whiting tight to the bank in 10 to 36 ft. Through summer count on 10 to 36 ft; the winter hold is 8 to 36 ft. If you only fish one area, make it SHOM-grid channel edge: a channel edge around 18 ft that scores prime in spring. Best bite is early morning. A small vertical jig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 36 ft | dawn & dusk | SHOM-grid channel edge (18 ft) | Small silver jig, Two-hook feather rig |
| Summer | 10 to 36 ft | dawn | Deepest basin (36 ft) | Small vertical jig |
| Fall | 6 to 36 ft | dusk | SHOM-grid channel edge (18 ft) | Small silver jig, Sparse feather rig |
| Winter | 8 to 36 ft | dusk | Deepest basin (36 ft) | Compact vertical jig |
Early season garfish use the shallows, holding in 1 to 15 ft. Expect a summer slide to 2 to 20 ft, then a winter hold in 11 to 36 ft. Put Shoreline point first on the milk run — a point near 3 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a slim casting spoon or a surface-skipping fly and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 15 ft | dawn & midday | Shoreline point (3 ft) | Slim silver spoon, Small inline spinner |
| Summer | 2 to 20 ft | dawn & dusk | Shoreline point (3 ft) | Slim casting spoon, Surface-skipping fly |
| Fall | 8 to 30 ft | dawn & dusk | SHOM-grid current seam (14 ft) | Weighted slim spoon, Small silver jig |
| Winter | 11 to 36 ft | midday | Deepest basin (36 ft) |

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 Pertuis Breton - South East 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.

Pertuis Breton - South East is about 36 ft (11 m) deep at its deepest point. 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.

The mixed roster combines exact-water records where available with habitat-filtered regional evidence; not every species is documented at this exact water, and it is not a promise of equal abundance or a catch on a particular trip.
