63,676-acre Baie de Seine. Middle 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 Seine estuary and eastern Normandy bay, an extensively surveyed nursery and mixed sand, channel and plume system. This page covers the middle east angler-scale survey window. The water tops out around 77 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.
Traced from the shoreline, Baie de Seine - Middle East runs 63,695 acres with 48.5 miles of edge. The basin is a simple one (shoreline index 1.4) — close to a bowl, so the structure on the chart matters more than the bank. Littoral water — the productive band under ~15 ft — makes up 17% of this chart. The basin spans about 12.7 mi end to end and 11.1 mi across at its widest. The nearest mapped water is Baie de Seine - South East, 9 mi to the south.
Baie de Seine — Middle East, France : carte SHOM officielle jusqu’à 23 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. As the season builds they drop to 2 to 30 ft, wintering in 10 to 55 ft. Fall european seabass concentrate at SHOM-grid current seam, a prime-rated current seam around 31 ft. Warm-month bites cluster around early morning and the evening. 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 (10 ft) | Paddle-tail soft plastic, Shallow minnow plug |
| Summer | 2 to 30 ft | dawn & dusk | SHOM-grid current seam (31 ft) | Surface lure, Paddle-tail soft plastic |
| Fall | 4 to 40 ft | dawn & dusk | SHOM-grid current seam (31 ft) | Slim metal lure, Minnow plug |
| Winter | 10 to 55 ft | midday | SHOM-grid channel edge (39 ft) | 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. If you only fish one area, make it Feeding flat: a feeding flat around 28 ft that scores prime in spring. Best bite is 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 | Feeding flat (28 ft) | Tiny bottom jig |
| Summer | 3 to 30 ft | dusk | Feeding flat (28 ft) | Light rolling-lead rig |
| Fall | 8 to 40 ft | dusk | SHOM-grid channel edge (39 ft) | Compact bottom jig |
| Winter | 20 to 70 ft | night | Deepest basin (77 ft) |
Spring european flounder on Baie de Seine - Middle East hold shallow, usually 5 to 25 ft. By summer they slide out to 6 to 35 ft, and by winter most fish are in 15 to 50 ft. The chart's best answer is Feeding flat — feeding flat, 28 ft, prime for summer. Prime time lands in 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 | Feeding flat (28 ft) | Small bucktail dragged on bottom |
| Summer | 6 to 35 ft | dawn & dusk | Feeding flat (28 ft) | Bottom jig with spinner blade |
| Fall | 8 to 40 ft | dusk | Feeding flat (28 ft) | Compact bottom jig |
| Winter | 15 to 50 ft | midday | Sharp break (54 ft) | Small bottom jig |
In spring, european plaice run shallow here, mostly 8 to 35 ft. Midsummer fish sit out in 6 to 40 ft before dropping to 23 to 77 ft for winter. Spring european plaice concentrate at Feeding flat, a prime-rated feeding flat around 28 ft. Fish it in early morning and the evening and you'll meet the bite. 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 | Feeding flat (28 ft) | Beaded flowing trace |
| Summer | 6 to 40 ft | dawn & dusk | Feeding flat (28 ft) | Light spooned bottom rig, Beaded trace |
| Fall | 10 to 50 ft | dusk | SHOM-grid channel edge (39 ft) | Beaded bottom trace |
| Winter | 23 to 77 ft | midday | Deepest basin (77 ft) |
In spring, whiting run shallow here, mostly 15 to 55 ft. Midsummer fish sit out in 20 to 70 ft before dropping to 15 to 70 ft for winter. Spring whiting concentrate at SHOM-grid channel edge, a prime-rated channel edge around 39 ft. Fish it in early morning and you'll meet the bite. You won't need more than a small vertical jig most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 55 ft | dawn & dusk | SHOM-grid channel edge (39 ft) | Small silver jig, Two-hook feather rig |

| Fall | 10 to 60 ft | dusk | SHOM-grid channel edge (39 ft) | Small silver jig, Sparse feather rig |
| Winter | 15 to 70 ft | dusk | SHOM-grid channel edge (39 ft) | Compact vertical jig |
Start shallow in spring: garfish sit in 1 to 15 ft that time of year. Summer pushes them deeper, 2 to 20 ft, and winter fish settle into 20 to 60 ft. The spot to know is Shoreline point, a point in about 10 ft of water that rates prime for garfish in spring. Warm-month bites cluster around early morning and the evening. Throw a slim casting spoon or a surface-skipping fly until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 15 ft | dawn & midday | Shoreline point (10 ft) | Slim silver spoon, Small inline spinner |
| Summer | 2 to 20 ft | dawn & dusk | Shoreline point (10 ft) | Slim casting spoon, Surface-skipping fly |
| Fall | 8 to 30 ft | dawn & dusk | SHOM-grid current seam (31 ft) | Weighted slim spoon, Small silver jig |
| Winter | 20 to 60 ft | midday | SHOM-grid current seam (31 ft) |

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 Seine - Middle 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.

Baie de Seine - Middle East is about 77 ft (23 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.

The mixed roster combines exact-water records where available with habitat-filtered regional evidence; not every species is documented at this exact water, and it is not a promise of equal abundance or a catch on a particular trip.
SHOM-grid current seam is the top-rated area: a current seam in about 31 ft of water that rates prime for european seabass in fall. The map above holds the full rated-spot list for every species and season.
For european seabass, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
Fishing on Baie de Seine - Middle East is regulated by the Légifrance (current French recreational sea-fishing minimum sizes). Check the official France regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
