14,250-acre Pertuis Breton. North West 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 north west angler-scale survey window. The water tops out around 84 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. What the data behind the map says about each species, season by season:
The drawn water covers 14,244 acres wrapped in 22.3 miles of bank. Nearly circular (index 1.3), so the story is the bottom, not the bank. Roughly 12% of the water is 15 ft or less, the band where the food chain lives. Figure 8.4 mi of water from one end to the other, 5 mi at the beam. Its nearest charted neighbour, Pertuis Breton - North Central, is 6 mi to the east.

Les profondeurs et les points de structure proviennent de la grille bathymétrique officielle du Shom. Les données servent à préparer la pêche et ne doivent jamais être utilisées pour la navigation.
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.

When the water first warms, european seabass slide up into 3 to 25 ft. By summer they slide out to 2 to 30 ft, and by winter most fish are in 10 to 55 ft. If you only fish one area, make it SHOM-grid current seam: a current seam around 34 ft that scores prime in fall. In summer the feeding windows fall in early morning and the evening. Keep a surface lure or a paddle-tail soft plastic rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Shoreline point (6 ft) | Paddle-tail soft plastic, Shallow minnow plug |
| Summer | 2 to 30 ft | dawn & dusk | SHOM-grid current seam (34 ft) | Surface lure, Paddle-tail soft plastic |
| Fall | 4 to 40 ft | dawn & dusk | SHOM-grid current seam (34 ft) | Slim metal lure, Minnow plug |
| Winter | 10 to 55 ft | midday | SHOM-grid channel edge (42 ft) | Slow soft-plastic shad, Suspending minnow |
In spring, common sole run shallow here, mostly 6 to 30 ft. Summer keeps them at 3 to 30 ft, and they winter in 20 to 70 ft. Spring common sole concentrate at Feeding flat, a prime-rated feeding flat around 17 ft. Fish it in the evening and you'll meet the bite. You won't need more than a light rolling-lead rig most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 6 to 30 ft | dusk | Feeding flat (17 ft) | Tiny bottom jig |
| Summer | 3 to 30 ft | dusk | Feeding flat (17 ft) | Light rolling-lead rig |
| Fall | 8 to 40 ft | dusk | SHOM-grid channel edge (42 ft) | Compact bottom jig |
| Winter | 20 to 70 ft | night | SHOM-grid channel edge (42 ft) |
The spring pattern is a shallow one: european flounder in 5 to 25 ft. As the season builds they drop to 6 to 35 ft, wintering in 15 to 50 ft. Top water on the chart: Feeding flat, a feeding flat in the 17 ft range, prime in spring. Time it for early morning and the evening. Summer baits: a bottom jig with spinner blade gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dusk | Feeding flat (17 ft) | Small bucktail dragged on bottom |
| Summer | 6 to 35 ft | dawn & dusk | Feeding flat (17 ft) | Bottom jig with spinner blade |
| Fall | 8 to 40 ft | dusk | Sharp break (39 ft) | Compact bottom jig |
| Winter | 15 to 50 ft | midday | Sharp break (39 ft) | Small bottom jig |
Early season european plaice use the shallows, holding in 8 to 35 ft. Expect a summer slide to 6 to 40 ft, then a winter hold in 25 to 80 ft. Put Feeding flat first on the milk run — a feeding flat near 17 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a light spooned bottom rig or a beaded trace and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 35 ft | dusk | Feeding flat (17 ft) | Beaded flowing trace |
| Summer | 6 to 40 ft | dawn & dusk | Feeding flat (17 ft) | Light spooned bottom rig, Beaded trace |
| Fall | 10 to 50 ft | dusk | SHOM-grid channel edge (42 ft) | Beaded bottom trace |
| Winter | 25 to 80 ft | midday | Deepest basin (79 ft) |
Early season whiting use the shallows, holding in 15 to 55 ft. Expect a summer slide to 20 to 70 ft, then a winter hold in 15 to 70 ft. Put SHOM-grid channel edge first on the milk run — a channel edge near 42 ft that grades prime for spring. In summer the feeding windows fall in early morning. Tie on a small vertical jig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 55 ft | dawn & dusk | SHOM-grid channel edge (42 ft) | Small silver jig, Two-hook feather rig |
| Summer | 20 to 70 ft | dawn | SHOM-grid channel edge (42 ft) | Small vertical jig |
| Fall | 10 to 60 ft | dusk | SHOM-grid channel edge (42 ft) | Small silver jig, Sparse feather rig |
| Winter | 15 to 70 ft | dusk | SHOM-grid channel edge (42 ft) | Compact vertical jig |
When the water first warms, garfish slide up into 1 to 15 ft. Summer is a 2 to 20 ft game here, winter a 20 to 60 ft one. Start at Shoreline point. It's a point holding about 6 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a slim casting spoon or a surface-skipping fly rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 15 ft | dawn & midday | Shoreline point (6 ft) | Slim silver spoon, Small inline spinner |
| Summer | 2 to 20 ft | dawn & dusk | Shoreline point (6 ft) | Slim casting spoon, Surface-skipping fly |
| Fall | 8 to 30 ft | dawn & dusk | SHOM-grid current seam (34 ft) | Weighted slim spoon, Small silver jig |
| Winter | 20 to 60 ft | midday | SHOM-grid current seam (34 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 - North West 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 - North West is about 84 ft (26 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.
Official coastal monitoring from Ifremer EVHOE and PELGAS regional survey evidence informs the european seabass, common sole, european flounder, european plaice, whiting, garfish, atlantic mackerel, thick-lipped grey mullet, flathead grey mullet, brill, thornback ray, european eel, atlantic salmon roster for Pertuis Breton - North West. 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.
SHOM-grid current seam is the top-rated area: a current seam in about 34 ft of water that rates prime for european seabass in fall. Scroll up to the map for the complete spot list by species and season.
For european seabass, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
Fishing on Pertuis Breton - North West is regulated by the Légifrance (current French recreational sea-fishing minimum sizes). Check the official France regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
