12,394-acre Baie de Morlaix. 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. Morlaix Bay and its island-studded approaches, with tidal channels, estuary influence and rock structure. This page covers the south west angler-scale survey window. The water tops out around 180 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.
Drawn out, this is 12,396 acres of water rimmed by 35.4 miles of bank. With a shoreline index of 2.3, this water is all arms and coves — edge habitat well beyond its acreage. The shallow band under 15 ft claims about 23% of the surface — that's where the groceries are. The basin spans about 11.4 mi end to end and 4.4 mi across at its widest. Closest neighbour on DepthScout: Baie de Morlaix - North West, 9 mi north of here.
Baie de Morlaix — South West, France : carte SHOM officielle jusqu’à 55 m; spots pour bar commun, sole commune. 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.

Spring puts european seabass in skinny water — 3 to 25 ft is the zone. Warm water sends them out to 2 to 30 ft; cold water stacks them in 10 to 55 ft. Shoreline point is the standout, a point at roughly 3 ft, rated good for fall european seabass. Plan around early morning and the evening in the warm months. A surface lure or a paddle-tail soft plastic covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Shoreline point (3 ft) | Paddle-tail soft plastic, Shallow minnow plug |
| Summer | 2 to 30 ft | dawn & dusk | Shoreline point (3 ft) | Surface lure, Paddle-tail soft plastic |
| Fall | 4 to 40 ft | dawn & dusk | Shoreline point (3 ft) | Slim metal lure, Minnow plug |
| Winter | 10 to 55 ft | midday | open water | Slow soft-plastic shad, Suspending minnow |
Come spring, look for common sole tight to the bank in 6 to 30 ft. Through summer count on 3 to 30 ft; the winter hold is 20 to 70 ft. Start at SHOM-grid flat. It's a feeding flat holding about 18 ft of water and rates prime come spring. Prime time lands in the evening. A light rolling-lead rig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 6 to 30 ft | dusk | SHOM-grid flat (18 ft) | Tiny bottom jig |
| Summer | 3 to 30 ft | dusk | SHOM-grid flat (18 ft) | Light rolling-lead rig |
| Fall | 8 to 40 ft | dusk | SHOM-grid flat (18 ft) | Compact bottom jig |
| Winter | 20 to 70 ft | night | open water |
Spring european flounder on Baie de Morlaix - South West hold shallow, usually 5 to 25 ft. They move out to 6 to 35 ft in summer and finish the year down in 15 to 50 ft. Put SHOM-grid flat first on the milk run — a feeding flat near 18 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a bottom jig with spinner blade.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dusk | SHOM-grid flat (18 ft) | Small bucktail dragged on bottom |

| Fall | 8 to 40 ft | dusk | SHOM-grid flat (18 ft) | Compact bottom jig |
| Winter | 15 to 50 ft | midday | SHOM-grid flat (18 ft) | Small bottom jig |
In spring, european plaice run shallow here, mostly 8 to 35 ft. Summer pushes them deeper, 6 to 40 ft, and winter fish settle into 25 to 80 ft. SHOM-grid flat is the standout, a feeding flat at roughly 18 ft, rated prime for spring european plaice. Time it for early morning and the evening. You won't need more than a light spooned bottom rig or a beaded trace most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 35 ft | dusk | SHOM-grid flat (18 ft) | Beaded flowing trace |
| Summer | 6 to 40 ft | dawn & dusk | SHOM-grid flat (18 ft) | Light spooned bottom rig, Beaded trace |
| Fall | 10 to 50 ft | dusk | SHOM-grid flat (18 ft) | Beaded bottom trace |
| Winter | 25 to 80 ft | midday | SHOM-grid channel edge (90 ft) |
In spring, whiting run shallow here, mostly 15 to 55 ft. Summer pushes them deeper, 20 to 70 ft, and winter fish settle into 15 to 70 ft. SHOM-grid current seam is the standout, a current seam at roughly 72 ft, rated good for summer whiting. Time it for early morning. You won't need more than a small vertical jig most summer days.

Start shallow in spring: garfish sit in 1 to 15 ft that time of year. Warm water sends them out to 2 to 20 ft; cold water stacks them in 20 to 60 ft. Top water on the chart: Shoreline point, a point in the 3 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a slim casting spoon or a surface-skipping fly until the fish tell you otherwise.

|---|---|---|---|---|
| Spring | 1 to 15 ft | dawn & midday | Shoreline point (3 ft) | Slim silver spoon, Small inline spinner |

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 Baie de Morlaix - 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.
