96,250-acre Iroise Sea. Middle West 1 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 exposed Iroise Sea from Ushant through the Brest approaches, with reefs, islands and strong Atlantic tide races. This page covers the middle west 1 angler-scale survey window. The water tops out around 384 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. Here's the year, species by species, as the scoring engine sees it.
The drawn water covers 96,070 acres wrapped in 72.3 miles of bank, with a single island in the mix. With a 1.7 development index there's bank structure worth casting at, in moderation. Littoral water — the productive band under ~15 ft — makes up 1% of this chart. Call it 18.2 mi long by 13.9 mi wide at the broadest reach. Its nearest charted neighbour, Iroise Sea - Middle West 2, is 10 mi to the east.
Iroise Sea — Middle West 1, France : carte SHOM officielle jusqu’à 117 m; spots pour bar commun, maquereau commun. 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 european seabass on Iroise Sea - Middle West 1 hold shallow, usually 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. The chart's best answer is Shoreline point — point, 43 ft, good for fall. Prime time lands in early morning and the evening. The summer box starts with a surface lure or a paddle-tail soft plastic.
| 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 | Shoreline point (43 ft) | Slim metal lure, Minnow plug |
| Winter | 10 to 55 ft | midday | open water | Slow soft-plastic shad, Suspending minnow |
Spring puts atlantic mackerel in skinny water — 5 to 45 ft is the zone. As the season builds they drop to 15 to 80 ft, wintering in 30 to 120 ft. Summer atlantic mackerel concentrate at Sharp break, a good-rated drop-off around 48 ft. Warm-month bites cluster around early morning and the evening. A feather rig or a small vertical jig covers the summer program.

Spring saithe (coalfish) on Iroise Sea - Middle West 1 hold shallow, usually 15 to 160 ft. By summer they slide out to 25 to 260 ft, and by winter most fish are in 45 to 320 ft. The chart's best answer is SHOM-grid current seam — current seam, 147 ft, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a speed jig or a heavy paddletail.

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 Iroise Sea - Middle West 1 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.
