20,568-acre Costa Oeste Asturias. Sector 04 Spain coastal fishing map with an exact official national water-body boundary, EMODnet 2024 CDI-audited Spanish hydrographic and research-survey/composite DTM contours, source-assessed fishing spots, official regional fish evidence, seasonal forage guidance, public-access review and current-rule links. Official Spanish WFD named coastal or transitional assessment water in Cantabrian Coast. This child is clipped to the exact source polygon and a trip-scale ownership window. Coverage classes and uncertainty limits are disclosed; this is a fishing-planning chart, not a navigation chart or catch forecast. The water tops out around 249 ft. The depth chart comes from EMODnet, with national hydrographic source-reference audit bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What the data behind the map says about each species, season by season:
The drawn water covers 20,574 acres wrapped in 29.5 miles of bank. A middling shoreline index (1.5) gives it some bays to work without being a maze. 6% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Call it 10.6 mi long by 4.5 mi wide at the broadest reach. Its nearest charted neighbour, Costa Oeste Asturias - Sector 05, is 11 mi to the east.
Occurrence evidence does not promise a catch or establish that retention is legal. Current seasons, closures, protected species, gear rules and local restrictions 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.

Come spring, look for european seabass tight to the bank in 3 to 25 ft. They move out to 2 to 30 ft in summer and finish the year down in 10 to 55 ft. If you only fish one area, make it Shoreline point: a point around 14 ft that scores good in fall. Best bite is early morning and the evening. A surface lure or a paddle-tail soft plastic is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Shoreline point (14 ft) | Paddle-tail soft plastic, Shallow minnow plug |
| Summer | 2 to 30 ft | dawn & dusk | Shoreline point (14 ft) | Surface lure, Paddle-tail soft plastic |
| Fall | 4 to 40 ft | dawn & dusk | Shoreline point (14 ft) | Slim metal lure, Minnow plug |
| Winter | 10 to 55 ft | midday | open water | Slow soft-plastic shad, Suspending minnow |
Start shallow in spring: gilthead seabream sit in 3 to 35 ft that time of year. Warm water sends them out to 2 to 45 ft; cold water stacks them in 20 to 100 ft. Fish it in early morning and the evening and you'll meet the bite.

The spring pattern is a shallow one: meagre in 12 to 80 ft. As the season builds they drop to 8 to 100 ft, wintering in 40 to 180 ft. Top water on the chart: Sharp break, a drop-off in the 104 ft range, good in winter. Time it for the evening.

Start shallow in spring: atlantic mackerel sit in 5 to 45 ft that time of year. Warm water sends them out to 15 to 80 ft; cold water stacks them in 30 to 120 ft. Top water on the chart: Sharp break, a drop-off in the 68 ft range, good in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a feather rig or a small vertical jig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 45 ft | dawn & dusk | Shoreline point (41 ft) | Mackerel feather rig, Small silver jig |
| Summer | 15 to 80 ft | dawn & dusk | Sharp break (68 ft) | Feather rig, Small vertical jig |
| Fall | 10 to 65 ft | dawn & dusk | Sharp break (68 ft) | Compact silver jig, Sparse feather rig |
| Winter | 30 to 120 ft | midday | Sharp break (104 ft) | Small deep jig |
Early season atlantic bonito use the shallows, holding in 15 to 100 ft. Even in summer they hold at 5 to 90 ft; winter keeps them in 50 to 220 ft. The chart's best answer is Shoreline point — point, 41 ft, prime for summer. Best bite is early morning and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 100 ft | dawn & dusk | Shoreline point (41 ft) | see map |
| Summer | 5 to 90 ft | dawn & dusk | Shoreline point (41 ft) | see map |
| Fall | 8 to 120 ft | dawn & dusk | Sharp break (104 ft) | see map |

Come spring, look for garfish tight to the bank in 1 to 15 ft. Expect a summer slide to 2 to 20 ft, then a winter hold in 20 to 60 ft. Start at Shoreline point. It's a point holding about 14 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A slim casting spoon or a surface-skipping fly is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 15 ft | dawn & midday | Shoreline point (14 ft) | Slim silver spoon, Small inline spinner |
| Summer | 2 to 20 ft | dawn & dusk | Shoreline point (14 ft) | Slim casting spoon, Surface-skipping fly |
| Fall | 8 to 30 ft | dawn & dusk | Shoreline point (14 ft) | Weighted slim spoon, Small silver jig |
| Winter | 20 to 60 ft | midday | open water |

Count 15 structure marks on this chart. The deepest, Deepest basin, sits near 249 ft.
MITECO 2025 national bathing-water census and coastal-domain review was reviewed, but no stable government record establishes a public fishing entrance, parking or launch for this exact mapped child. This is an access-evidence gap, not a claim that public access does not exist. Verify land ownership, port and harbour rules, protected areas, local signs, parking, safety, permits and fishing 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 Spain waters are set by the Spanish Ministry of Agriculture, Fisheries and Food (marine recreational fishing) — and special regulations can apply to Costa Oeste Asturias - Sector 04 specifically, so confirm the current rules before you fish. Check Spain's live national, autonomous-community, EU and protected-area rules before every coastal trip. Licences for shore, boat and underwater fishing, PescaREC registration or reporting, protected-species authorizations, minimum sizes, quotas, closures, gear limits and marine-reserve permits can differ between exterior and interior waters and can change during the season. Recreational fishing is allowed only in specified zones of some reserves and is commonly subject to a special authorization. A WFD boundary, source-audited contour, fishing-spot marker or bathing-water record is planning context only and never grants fishing, retention, shore entry, parking, launching, port access or safe navigation permission.

Costa Oeste Asturias - Sector 04 is about 249 ft (76 m) deep at its deepest point. The depth chart comes from EMODnet, with national hydrographic source-reference audit bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Official coastal monitoring from Spain national fisheries and coastal monitoring agencies informs the european seabass, gilthead seabream, meagre, atlantic mackerel, atlantic bonito, garfish, common sole, thick-lipped grey mullet roster for Costa Oeste Asturias - Sector 04. 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.
Shoreline point is the top-rated area: a point in about 14 ft of water that rates prime for garfish in spring. Scroll up to the map for the complete spot list by 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 Costa Oeste Asturias - Sector 04 is regulated by the Spanish Ministry of Agriculture, Fisheries and Food (marine recreational fishing). Check the official Spain regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
