75,130-acre East Cotentin Coast. Middle West 4 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 eastern Cotentin coast from Utah Beach to Barfleur, including roadstead, harbor and tide-race structure. This page covers the middle west 4 angler-scale survey window. The water tops out around 149 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. Species by species, here's what the data says the year looks like.
Drawn out, this is 75,071 acres of water rimmed by 43.4 miles of bank. Its 1.1 shoreline index means few bank features; the contours below do the pattern work. Roughly 0% of the water is 15 ft or less, the band where the food chain lives. Figure 15.1 mi of water from one end to the other, 13.8 mi at the beam. For a second option, East Cotentin Coast - South West 4 lies 9 mi south.

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. 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 | 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 |
Spring atlantic mackerel on East Cotentin Coast - Middle West 4 hold shallow, usually 5 to 45 ft. By summer they slide out to 15 to 80 ft, and by winter most fish are in 30 to 120 ft. The chart's best answer is SHOM-grid current seam — current seam, 62 ft, prime for fall. Prime time lands in early morning and the evening. The summer box starts with a feather rig or a small vertical jig.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 45 ft | dawn & dusk | open water | Mackerel feather rig, Small silver jig |
| Summer | 15 to 80 ft | dawn & dusk | SHOM-grid current seam (62 ft) | Feather rig, Small vertical jig |
| Fall | 10 to 65 ft | dawn & dusk | SHOM-grid current seam (62 ft) | Compact silver jig, Sparse feather rig |
| Winter | 30 to 120 ft | midday | Sharp break (128 ft) | Small deep 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 25 to 80 ft for winter. Winter european plaice concentrate at SHOM-grid channel edge, a good-rated channel edge around 75 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 | 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 (75 ft) |
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 SHOM-grid channel edge: a channel edge around 75 ft that scores good in winter. 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 | open water | Tiny bottom jig |
| Summer | 3 to 30 ft | dusk | open water | Light rolling-lead rig |

Spring european flounder on East Cotentin Coast - Middle West 4 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. Prime time lands in early morning and the evening. The summer box starts with a bottom jig with spinner blade.

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 East Cotentin Coast - Middle West 4 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.
