34,615-acre Côte de Granit Rose. South 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 north Brittany granite coast, with island passages, reefs, kelp edges and exposed Channel points. This page covers the south west angler-scale survey window. The water tops out around 192 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.
Côte de Granit Rose - South West maps at 34,624 acres behind 42.7 miles of shoreline — one island included. A middling shoreline index (1.6) gives it some bays to work without being a maze. Littoral water — the productive band under ~15 ft — makes up 13% of this chart. Figure 9.9 mi of water from one end to the other, 9.1 mi at the beam. Its nearest charted neighbour, Baie de Morlaix - North East, is 10 mi to the northwest.
Côte de Granit Rose — South West, France : carte SHOM officielle jusqu’à 59 m; spots pour bar commun, maquereau commun. Pour préparer la pêche, jamais pour naviguer. 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. Summer is a 2 to 30 ft game here, winter a 10 to 55 ft one. Start at Shoreline point. It's a point holding about 4 ft of water and rates good come fall. The feeding windows run 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 (4 ft) | Paddle-tail soft plastic, Shallow minnow plug |
| Summer | 2 to 30 ft | dawn & dusk | Shoreline point (4 ft) | Surface lure, Paddle-tail soft plastic |
| Fall | 4 to 40 ft | dawn & dusk | Shoreline point (4 ft) | Slim metal lure, Minnow plug |
| Winter | 10 to 55 ft | midday | open water | Slow soft-plastic shad, Suspending minnow |
The spring pattern is a shallow one: atlantic mackerel in 5 to 45 ft. Midsummer fish sit out in 15 to 80 ft before dropping to 30 to 120 ft for winter. The spot to know is SHOM-grid current seam, a current seam in about 77 ft of water that rates good for atlantic mackerel in summer. Plan around early morning and the evening in the warm months. Summer baits: a feather rig or a small vertical jig gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 45 ft | dawn & dusk | Shoreline point (4 ft) | Mackerel feather rig, Small silver jig |
| Summer | 15 to 80 ft | dawn & dusk | SHOM-grid current seam (77 ft) | Feather rig, Small vertical jig |
| Fall | 10 to 65 ft | dawn & dusk | SHOM-grid current seam (77 ft) | Compact silver jig, Sparse feather rig |
| Winter | 30 to 120 ft | midday | SHOM-grid channel edge (96 ft) | Small deep jig |
Start shallow in spring: atlantic pollock sit in 8 to 100 ft that time of year. Summer pushes them deeper, 12 to 150 ft, and winter fish settle into 31 to 192 ft. The spot to know is Sharp break, a drop-off in about 147 ft of water that rates prime for atlantic pollock in winter. Warm-month bites cluster around early morning and the evening. Throw a surface plug or a baitfish swimbait until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 100 ft | dawn & dusk | Rock reef (6 ft) | Sandeel-pattern lure, Soft-plastic shad |
| Summer | 12 to 150 ft | dawn & dusk | Shoreline point (4 ft) | Surface plug, Baitfish swimbait |
| Fall | 15 to 160 ft | dawn | Rock reef (6 ft) | Metal jig, Minnow plug |
| Winter | 31 to 192 ft | midday | Sharp break (147 ft) | Slow metal jig, Weighted soft plastic |
When the water first warms, saithe (coalfish) slide up into 15 to 160 ft. Summer is an 18 to 192 ft game here, winter a 27 to 192 ft one. Start at SHOM-grid current seam. It's a current seam holding about 77 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a speed jig or a heavy paddletail rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 160 ft | dawn & dusk | SHOM-grid current seam (77 ft) | Slim metal jig, Paddletail |

| Fall | 17 to 192 ft | dawn & dusk | SHOM-grid current seam (77 ft) | Metal jig, Baitfish swimbait |
| Winter | 27 to 192 ft | midday | Deepest basin (192 ft) | Heavy vertical jig |
Start shallow in spring: atlantic cod sit in 20 to 100 ft that time of year. Summer pushes them deeper, 45 to 180 ft, and winter fish settle into 44 to 192 ft. The spot to know is Deepest basin, a deep basin in about 192 ft of water that rates prime for atlantic cod in winter. Warm-month bites cluster around early morning. Throw a heavy metal jig or a large soft-plastic jig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 20 to 100 ft | dawn | Rock reef (6 ft) | Diamond jig, Heavy bucktail |

When the water first warms, ling slide up into 34 to 192 ft. There's no big seasonal slide here — summer means 32 to 192 ft, winter 36 to 192 ft. Start at Sharp break. It's a drop-off holding about 147 ft of water and rates prime come spring. The feeding windows run midday. Keep a heavy vertical jig 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 Côte de Granit Rose - South 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.
