63,667-acre Côte de Granit Rose. North 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 north Brittany granite coast, with island passages, reefs, kelp edges and exposed Channel points. This page covers the north east angler-scale survey window. The water tops out around 222 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 follows comes from the same scoring engine that paints the spots above.
The drawn water covers 63,759 acres wrapped in 66.9 miles of bank — 2 islands included. With a 1.9 development index there's bank structure worth casting at, in moderation. Roughly 7% of the water is 15 ft or less, the band where the food chain lives. Call it 13.8 mi long by 13.7 mi wide at the broadest reach. Its nearest charted neighbour, Côte de Granit Rose - North Central, is 11 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 Côte de Granit Rose - North East hold shallow, usually 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. The chart's best answer is Shoreline point — point, 28 ft, good for fall. Prime time lands in 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 flat (22 ft) | Paddle-tail soft plastic, Shallow minnow plug |
| Summer | 2 to 30 ft | dawn & dusk | Shoreline point (28 ft) | Surface lure, Paddle-tail soft plastic |
| Fall | 4 to 40 ft | dawn & dusk | Shoreline point (28 ft) | Slim metal lure, Minnow plug |
| Winter | 10 to 55 ft | midday | open water | Slow soft-plastic shad, Suspending minnow |
Spring puts atlantic mackerel in skinny water — 5 to 45 ft is the zone. As the season builds they drop to 15 to 80 ft, wintering in 30 to 120 ft. Spring atlantic mackerel concentrate at Shoreline point, a good-rated point around 28 ft. Warm-month bites cluster around early morning and the evening. A feather rig or a small vertical jig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 45 ft | dawn & dusk | Shoreline point (28 ft) | Mackerel feather rig, Small silver jig |

| Fall | 10 to 65 ft | dawn & dusk | Shoreline point (28 ft) | Compact silver jig, Sparse feather rig |
| Winter | 30 to 120 ft | midday | Sharp break (129 ft) | Small deep jig |
Spring puts atlantic pollock in skinny water — 8 to 100 ft is the zone. Warm water sends them out to 12 to 150 ft; cold water stacks them in 35 to 220 ft. Rock reef is the standout, a rock pile at roughly 9 ft, rated prime for spring atlantic pollock. Plan around early morning and the evening in the warm months. A surface plug or a baitfish swimbait covers the summer program.

Spring saithe (coalfish) on Côte de Granit Rose - North East hold shallow, usually 15 to 160 ft. By summer they slide out to 21 to 222 ft, and by winter most fish are in 31 to 222 ft. The chart's best answer is SHOM-grid current seam — current seam, 89 ft, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a speed jig or a heavy paddletail.
| Season | Depth | Best window | Start at | Go-to baits |

No official 2025 EEA designated bathing-water point matched within 400 metres of this SHOM-grid shoreline. This is an access-evidence gap, not a statement that public fishing access does not exist. Verify local fishing rights, land ownership, posted restrictions, protected areas, tidal and surf safety, and municipal permission before entry.
Private land and private launches need the owner's permission — please ask first.
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 Côte de Granit Rose - 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.
