7,356-acre Concarneau and Bénodet Coast. North West 2 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 north west 2 angler-scale survey window. The water tops out around 66 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. Below is the species-by-species picture, pulled from the same data the map uses.
The outline encloses 7,355 acres, worked by 17.8 miles of shoreline. A middling shoreline index (1.5) gives it some bays to work without being a maze. About 38% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. End to end it runs roughly 4.9 mi, about 4 mi across. Its nearest charted neighbour, Concarneau and Bénodet Coast - North West 1, is 6 mi to the west.

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 26 ft that scores prime in summer. 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 | SHOM-grid current seam (26 ft) | Paddle-tail soft plastic, Shallow minnow plug |
| Summer | 2 to 30 ft | dawn & dusk | SHOM-grid current seam (26 ft) | Surface lure, Paddle-tail soft plastic |
| Fall | 4 to 40 ft | dawn & dusk | SHOM-grid current seam (26 ft) | Slim metal lure, Minnow plug |
| Winter | 10 to 55 ft | midday | SHOM-grid channel edge (33 ft) | Slow soft-plastic shad, Suspending minnow |
The spring pattern is a shallow one: atlantic mackerel in 5 to 45 ft. As the season builds they drop to 12 to 66 ft, wintering in 17 to 66 ft. Top water on the chart: Deepest basin, a deep basin in the 65 ft range, prime in summer. Time it for early morning and the evening. 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 | SHOM-grid current seam (26 ft) | Mackerel feather rig, Small silver jig |
| Summer | 12 to 66 ft | dawn & dusk | Deepest basin (65 ft) | Feather rig, Small vertical jig |
| Fall | 10 to 65 ft | dawn & dusk | SHOM-grid current seam (26 ft) | Compact silver jig, Sparse feather rig |
| Winter | 17 to 66 ft | midday | Deepest basin (65 ft) | Small deep jig |
Start shallow in spring: atlantic pollock sit in 5 to 66 ft that time of year. They don't go far with the seasons — 5 to 66 ft covers summer, 11 to 66 ft covers winter. Top water on the chart: SHOM-grid point, a point in the 20 ft range, prime in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a surface plug or a baitfish swimbait until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 66 ft | dawn & dusk | Rock reef (2 ft) | Sandeel-pattern lure, Soft-plastic shad |

| Fall | 6 to 66 ft | dawn | SHOM-grid point (20 ft) | Metal jig, Minnow plug |
| Winter | 11 to 66 ft | midday | Sharp break (28 ft) | Slow metal jig, Weighted soft plastic |
When the water first warms, saithe (coalfish) slide up into 6 to 66 ft. There's no big seasonal slide here — summer means 6 to 66 ft, winter 9 to 66 ft. If you only fish one area, make it SHOM-grid current seam: a current seam around 26 ft that scores prime in spring. In summer the feeding windows fall in 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 | 6 to 66 ft | dawn & dusk | SHOM-grid current seam (26 ft) | Slim metal jig, Paddletail |
| Summer | 6 to 66 ft | dawn & dusk | Sharp break (28 ft) | Speed jig, Heavy paddletail |
| Fall | 6 to 66 ft | dawn & dusk | SHOM-grid current seam (26 ft) | Metal jig, Baitfish swimbait |
| Winter | 9 to 66 ft | midday | Deepest basin (65 ft) | Heavy vertical jig |
Start shallow in spring: atlantic cod sit in 13 to 66 ft that time of year. They don't go far with the seasons — 17 to 66 ft covers summer, 15 to 66 ft covers winter. Top water on the chart: Deepest basin, a deep basin in the 65 ft range, prime in winter. Fish it in early morning and you'll meet the bite. 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 | 13 to 66 ft | dawn | Sharp break (28 ft) | Diamond jig, Heavy bucktail |
| Summer | 17 to 66 ft | dawn | Deepest basin (65 ft) | Heavy metal jig, Large soft-plastic jig |

| Winter | 15 to 66 ft | midday | Deepest basin (65 ft) | Heavy vertical jig |
When the water first warms, ling slide up into 12 to 66 ft. There's no big seasonal slide here — summer means 11 to 66 ft, winter 12 to 66 ft. If you only fish one area, make it Sharp break: a drop-off around 28 ft that scores prime in spring. In summer the feeding windows fall in midday. Keep a heavy vertical jig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 12 to 66 ft | midday | Sharp break (28 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 - North West 2 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.

Concarneau and Bénodet Coast - North West 2 is about 66 ft (20 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.
