81,630-acre Baie de Seine. Middle 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 Seine estuary and eastern Normandy bay, an extensively surveyed nursery and mixed sand, channel and plume system. This page covers the middle west angler-scale survey window. The water tops out around 139 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. The season-by-season read for each species follows, from the map's own numbers.
Traced from the shoreline, Baie de Seine - Middle West runs 81,582 acres with 45.1 miles of edge. At index 1.1 the outline is almost a bowl — read the depth changes, not the shoreline. 0% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Tip to tip the water measures near 11.8 mi with a 10.9-mi widest point. The nearest mapped water is Baie de Seine - South West, 9 mi to the south.
Baie de Seine — Middle West, France : carte SHOM officielle jusqu’à 42 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.

Start shallow in spring: european seabass sit in 3 to 25 ft that time of year. Warm water sends them out to 2 to 30 ft; cold water stacks them in 10 to 55 ft. Fish it in early morning and the evening and you'll meet the bite. Throw a surface lure or a paddle-tail soft plastic until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | open water | Paddle-tail soft plastic, Shallow minnow plug |
| Summer | 2 to 30 ft | dawn & dusk | open water | Surface lure, Paddle-tail soft plastic |
| Fall | 4 to 40 ft | dawn & dusk | open water | Slim metal lure, Minnow plug |
| Winter | 10 to 55 ft | midday | open water | Slow soft-plastic shad, Suspending minnow |
Early season common sole use the shallows, holding in 6 to 30 ft. Even in summer they hold at 3 to 30 ft; winter keeps them in 20 to 70 ft. Put SHOM-grid channel edge first on the milk run — a channel edge near 70 ft that grades good for winter. In summer the feeding windows fall in the evening. Tie on a light rolling-lead rig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 6 to 30 ft | dusk | open water | Tiny bottom jig |
| Summer | 3 to 30 ft | dusk | open water | Light rolling-lead rig |
| Fall | 8 to 40 ft | dusk | open water | Compact bottom jig |
| Winter | 20 to 70 ft | night | SHOM-grid channel edge (70 ft) |
Come spring, look for european flounder tight to the bank in 5 to 25 ft. They move out to 6 to 35 ft in summer and finish the year down in 15 to 50 ft. Best bite is early morning and the evening. A bottom jig with spinner blade is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dusk | open water | Small bucktail dragged on bottom |
| Summer | 6 to 35 ft | dawn & dusk | open water | Bottom jig with spinner blade |
| Fall | 8 to 40 ft | dusk | open water | Compact bottom jig |
| Winter | 15 to 50 ft | midday | open water | Small bottom jig |
Start shallow in spring: european plaice sit in 8 to 35 ft that time of year. Summer pushes them deeper, 6 to 40 ft, and winter fish settle into 25 to 80 ft. The spot to know is SHOM-grid channel edge, a channel edge in about 70 ft of water that rates good for european plaice in winter. Warm-month bites cluster around early morning and the evening. Throw a light spooned bottom rig or a beaded trace until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 35 ft | dusk | open water | Beaded flowing trace |
| Summer | 6 to 40 ft | dawn & dusk | open water | Light spooned bottom rig, Beaded trace |
| Fall | 10 to 50 ft | dusk | open water | Beaded bottom trace |
| Winter | 25 to 80 ft | midday | SHOM-grid channel edge (70 ft) |
Start shallow in spring: whiting sit in 15 to 55 ft that time of year. Summer pushes them deeper, 20 to 70 ft, and winter fish settle into 15 to 70 ft. The spot to know is SHOM-grid channel edge, a channel edge in about 70 ft of water that rates good for whiting in winter. Warm-month bites cluster around early morning. Throw a small vertical jig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 55 ft | dawn & dusk | SHOM-grid channel edge (70 ft) | Small silver jig, Two-hook feather rig |
| Summer | 20 to 70 ft | dawn | SHOM-grid channel edge (70 ft) | Small vertical jig |
| Fall | 10 to 60 ft | dusk | SHOM-grid channel edge (70 ft) | Small silver jig, Sparse feather rig |
| Winter | 15 to 70 ft | dusk | SHOM-grid channel edge (70 ft) | Compact vertical jig |
Spring puts garfish in skinny water — 1 to 15 ft is the zone. Warm water sends them out to 2 to 20 ft; cold water stacks them in 20 to 60 ft. Plan around early morning and the evening in the warm months. A slim casting spoon or a surface-skipping fly covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 15 ft | dawn & midday | open water | Slim silver spoon, Small inline spinner |
| Summer | 2 to 20 ft | dawn & dusk | open water | Slim casting spoon, Surface-skipping fly |
| Fall | 8 to 30 ft | dawn & dusk | open water | Weighted slim spoon, Small silver jig |
| Winter | 20 to 60 ft | midday | open water |

No official 2025 EEA designated bathing-water point matched within 400 metres of this SHOM-grid shoreline. This is an access-evidence gap, not a statement that public fishing access does not exist. Verify local fishing rights, land ownership, posted restrictions, protected areas, tidal and surf safety, and municipal permission before entry.
Private land and private launches need the owner's permission — please ask first.
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 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.
