70,639-acre Concarneau and Bénodet Coast. South West 1 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 south Finistère coast around Concarneau and Bénodet, with archipelagos, estuary mouths and rocky Atlantic structure. This page covers the south west 1 angler-scale survey window. The water tops out around 291 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.
Drawn out, this is 70,544 acres of water rimmed by 49.2 miles of bank, with 2 islands in the mix. The basin is a simple one (shoreline index 1.3) — close to a bowl, so the structure on the chart matters more than the bank. 5% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Tip to tip the water measures near 15.1 mi with a 14.7-mi widest point. The nearest mapped water is Concarneau and Bénodet Coast - North West 1, 8 mi to the north.
Concarneau and Bénodet Coast — South West 1, France : carte SHOM officielle jusqu’à 89 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.

In spring, european seabass run shallow here, mostly 3 to 25 ft. Summer pushes them deeper, 2 to 30 ft, and winter fish settle into 10 to 55 ft. Shoreline point is the standout, a point at roughly 8 ft, rated good for fall european seabass. Time it for early morning and the evening. You won't need more than a surface lure or a paddle-tail soft plastic most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Shoreline point (8 ft) | Paddle-tail soft plastic, Shallow minnow plug |
| Summer | 2 to 30 ft | dawn & dusk | Shoreline point (8 ft) | Surface lure, Paddle-tail soft plastic |
| Fall | 4 to 40 ft | dawn & dusk | Shoreline point (8 ft) | Slim metal lure, Minnow plug |
| Winter | 10 to 55 ft | midday | open water | Slow soft-plastic shad, Suspending minnow |
Early season atlantic mackerel use the shallows, holding in 5 to 45 ft. Expect a summer slide to 15 to 80 ft, then a winter hold in 30 to 120 ft. Put Sharp break first on the milk run — a drop-off near 99 ft that grades good for winter. In summer the feeding windows fall in early morning and the evening. Tie on a feather rig or a small vertical jig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 45 ft | dawn & dusk | Shoreline point (8 ft) | Mackerel feather rig, Small silver jig |
| Summer | 15 to 80 ft | dawn & dusk | Sharp break (99 ft) | Feather rig, Small vertical jig |
| Fall | 10 to 65 ft | dawn & dusk | Shoreline point (8 ft) | Compact silver jig, Sparse feather rig |
| Winter | 30 to 120 ft | midday | Sharp break (99 ft) | Small deep jig |
Come spring, look for atlantic pollock tight to the bank in 8 to 100 ft. Expect a summer slide to 12 to 150 ft, then a winter hold in 35 to 220 ft. Start at Sharp break. It's a drop-off holding about 99 ft of water and rates prime come winter. Prime time lands in early morning and the evening. A surface plug or a baitfish swimbait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 100 ft | dawn & dusk | Rock reef (7 ft) | Sandeel-pattern lure, Soft-plastic shad |
| Summer | 12 to 150 ft | dawn & dusk | Shoreline point (8 ft) | Surface plug, Baitfish swimbait |
| Fall | 15 to 160 ft | dawn | Rock reef (7 ft) | Metal jig, Minnow plug |
| Winter | 35 to 220 ft | midday | Sharp break (99 ft) | Slow metal jig, Weighted soft plastic |
In spring, saithe (coalfish) run shallow here, mostly 15 to 160 ft. Summer pushes them deeper, 25 to 260 ft, and winter fish settle into 41 to 291 ft. SHOM-grid current seam is the standout, a current seam at roughly 116 ft, rated prime for spring saithe (coalfish). Time it for early morning and the evening. You won't need more than a speed jig or a heavy paddletail most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 160 ft | dawn & dusk | SHOM-grid current seam (116 ft) | Slim metal jig, Paddletail |
| Summer | 25 to 260 ft | dawn & dusk | Sharp break (99 ft) | Speed jig, Heavy paddletail |
| Fall | 20 to 220 ft | dawn & dusk | SHOM-grid current seam (116 ft) | Metal jig, Baitfish swimbait |
| Winter | 41 to 291 ft | midday | Deepest basin (291 ft) | Heavy vertical jig |
Come spring, look for atlantic cod tight to the bank in 20 to 100 ft. Expect a summer slide to 45 to 180 ft, then a winter hold in 50 to 220 ft. Start at Rock reef. It's a rock pile holding about 7 ft of water and rates good come spring. Prime time lands in early morning. A heavy metal jig or a large soft-plastic jig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 20 to 100 ft | dawn | Rock reef (7 ft) | Diamond jig, Heavy bucktail |
| Summer | 45 to 180 ft | dawn | Sharp break (99 ft) | Heavy metal jig, Large soft-plastic jig |

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 Concarneau and Bénodet Coast - South West 1 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.
