99,798-acre Roussillon Coast. North 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 sandy Roussillon shore around Perpignan, with river mouths, beach troughs and harbor approaches. This page covers the north east angler-scale survey window. The water tops out around 274 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 is how the season plays out for each species, straight from the data behind the map.
Roussillon Coast - North East maps at 99,769 acres behind 49.8 miles of shoreline. A shoreline index of 1.1 says round and simple: fish relate to depth changes here, not shoreline features. About 0% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. End to end it runs roughly 13.6 mi, about 13.2 mi across. If the bite dies, Roussillon Coast - North West is 7 mi to the west.

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.

When the water first warms, european seabass slide up into 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. If you only fish one area, make it SHOM-grid flat: a feeding flat around 29 ft that scores good in summer. In summer the feeding windows fall in early morning and the evening. Keep a surface lure or a paddle-tail soft plastic rigged through the warm months.
| 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 | SHOM-grid flat (29 ft) | Surface lure, Paddle-tail soft plastic |
| Fall | 4 to 40 ft | dawn & dusk | Shoreline point (48 ft) | Slim metal lure, Minnow plug |
| Winter | 10 to 55 ft | midday | open water | Slow soft-plastic shad, Suspending minnow |
In spring, common sole run shallow here, mostly 6 to 30 ft. Summer keeps them at 3 to 30 ft, and they winter in 20 to 70 ft. Spring common sole concentrate at SHOM-grid flat, a prime-rated feeding flat around 29 ft. Fish it in the evening and you'll meet the bite. You won't need more than a light rolling-lead rig most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 6 to 30 ft | dusk | SHOM-grid flat (29 ft) | Tiny bottom jig |
| Summer | 3 to 30 ft | dusk | SHOM-grid flat (29 ft) | Light rolling-lead rig |
| Fall | 8 to 40 ft | dusk | SHOM-grid flat (29 ft) | Compact bottom jig |
| Winter | 20 to 70 ft | night | open water |
The spring pattern is a shallow one: atlantic mackerel in 5 to 45 ft. As the season builds they drop to 15 to 80 ft, wintering in 30 to 120 ft. Top water on the chart: Sharp break, a drop-off in the 56 ft range, good in summer. Time it for early morning and the evening. Summer baits: a feather rig or a small vertical jig gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 45 ft | dawn & dusk | Shoreline point (48 ft) | Mackerel feather rig, Small silver jig |
| Summer | 15 to 80 ft | dawn & dusk | Sharp break (56 ft) | Feather rig, Small vertical jig |
| Fall | 10 to 65 ft | dawn & dusk | Sharp break (56 ft) | Compact silver jig, Sparse feather rig |
| Winter | 30 to 120 ft | midday | Sharp break (56 ft) | Small deep jig |
When the water first warms, garfish slide up into 1 to 15 ft. Summer is a 2 to 20 ft game here, winter a 20 to 60 ft one. Start at Sharp break. It's a drop-off holding about 56 ft of water and rates good come winter. The feeding windows run early morning and the evening. Keep a slim casting spoon or a surface-skipping fly rigged through the warm months.
| 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 | Sharp break (56 ft) |
When the water first warms, thick-lipped grey mullet slide up into 1 to 15 ft. By summer they slide out to 1 to 18 ft, and by winter most fish are in 8 to 35 ft. In summer the feeding windows fall in early morning and midday. Keep a bread fly or a small shrimp fly rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 15 ft | dusk | open water | Bread fly, Tiny algae-pattern fly |

| Winter | 8 to 35 ft | midday | open water |
Start shallow in spring: flathead grey mullet sit in 2 to 18 ft that time of year. Warm water sends them out to 1 to 22 ft; cold water stacks them in 12 to 45 ft. Top water on the chart: SHOM-grid flat, a feeding flat in the 29 ft range, good in summer. Fish it in early morning and midday and you'll meet the bite. Throw a bread fly or a small algae-pattern fly until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 18 ft | dusk | open water | Bread fly, Tiny shrimp fly |

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 Roussillon Coast - North 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.

Roussillon Coast - North East is about 274 ft (84 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.

SHOM-grid flat is the top-rated area: a feeding flat in about 29 ft of water that rates prime for common sole in spring. 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.
