35,966-acre Saint-Malo and Rance. North East France saltwater fishing map with official SHOM 20 m bathymetry, source-qualified fishing spots, official regional fish evidence, seasonal forage guidance, public shore-use context and current-rule links. Saint-Malo roadstead, the Rance mouth and nearby tidal islands, with constricted current and rock-to-sand breaks. This page covers the north east angler-scale survey window. The water tops out around 87 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. Species by species, here's what the data says the year looks like.
Saint-Malo and Rance - North East maps at 35,987 acres behind 56.9 miles of shoreline — 11 islands included. With a 2.1 development index there's bank structure worth casting at, in moderation. Roughly 16% of the water is 15 ft or less, the band where the food chain lives. Tip to tip the water measures near 12.5 mi with an 8.2-mi widest point. Golfe Normand-Breton - North West 3 sits 4 mi east — the closest neighbouring chart.

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. Summer is a 2 to 30 ft game here, winter a 10 to 55 ft one. The chart's best answer is SHOM-grid current seam — current seam, 30 ft, prime for summer. Best bite is 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 (4 ft) | Paddle-tail soft plastic, Shallow minnow plug |
| Summer | 2 to 30 ft | dawn & dusk | SHOM-grid current seam (30 ft) | Surface lure, Paddle-tail soft plastic |
| Fall | 4 to 40 ft | dawn & dusk | SHOM-grid current seam (30 ft) | Slim metal lure, Minnow plug |
| Winter | 10 to 55 ft | midday | SHOM-grid channel edge (38 ft) | 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. The spot to know is SHOM-grid channel edge, a channel edge in about 38 ft of water that rates prime for common sole in fall. Warm-month bites cluster around the evening. Throw a light rolling-lead rig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 6 to 30 ft | dusk | SHOM-grid current seam (30 ft) | Tiny bottom jig |
| Summer | 3 to 30 ft | dusk | SHOM-grid current seam (30 ft) | Light rolling-lead rig |
| Fall | 8 to 40 ft | dusk | SHOM-grid channel edge (38 ft) | Compact bottom jig |
| Winter | 20 to 70 ft | night | SHOM-grid channel edge (38 ft) |
In spring, european flounder run shallow here, mostly 5 to 25 ft. Midsummer fish sit out in 6 to 35 ft before dropping to 15 to 50 ft for winter. Fall european flounder concentrate at Sharp break, a prime-rated drop-off around 18 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a bottom jig with spinner blade most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dusk | Sharp break (18 ft) | Small bucktail dragged on bottom |
| Summer | 6 to 35 ft | dawn & dusk | Sharp break (18 ft) | Bottom jig with spinner blade |
| Fall | 8 to 40 ft | dusk | Sharp break (18 ft) | Compact bottom jig |
| Winter | 15 to 50 ft | midday | Sharp break (18 ft) | Small bottom jig |
When the water first warms, european plaice slide up into 8 to 35 ft. Summer is a 6 to 40 ft game here, winter a 25 to 80 ft one. Start at Feeding flat.

Keep a light spooned bottom rig or a beaded trace rigged through the warm months.

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 Saint-Malo and Rance - North 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.
