29,547-acre Castro Costa 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 282 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. Here's the year, species by species, as the scoring engine sees it.
The outline encloses 29,563 acres, worked by 31.5 miles of shoreline. The basin is a simple one (shoreline index 1.3) — close to a bowl, so the structure on the chart matters more than the bank. Littoral water — the productive band under ~15 ft — makes up 2% of this chart. End to end it runs roughly 11.2 mi, about 8.4 mi across. Cantabria-Matxitxako - West sits 8 mi east — the closest neighbouring chart.
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.

When the water first warms, european seabass slide up into 3 to 25 ft. Summer is a 2 to 30 ft game here, winter a 10 to 55 ft one. Start at Shoreline point. It's a point holding about 19 ft of water and rates good come fall. The feeding windows run 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 | Shoreline point (19 ft) | Paddle-tail soft plastic, Shallow minnow plug |
| Summer | 2 to 30 ft | dawn & dusk | Shoreline point (19 ft) | Surface lure, Paddle-tail soft plastic |
| Fall | 4 to 40 ft | dawn & dusk | Shoreline point (19 ft) | Slim metal lure, Minnow plug |
| Winter | 10 to 55 ft | midday | open water | Slow soft-plastic shad, Suspending minnow |
The spring pattern is a shallow one: gilthead seabream in 3 to 35 ft. Midsummer fish sit out in 2 to 45 ft before dropping to 20 to 100 ft for winter. Plan around early morning and the evening in the warm months.

Start shallow in spring: meagre sit in 12 to 80 ft that time of year. Summer pushes them deeper, 8 to 100 ft, and winter fish settle into 40 to 180 ft. The spot to know is Sharp break, a drop-off in about 68 ft of water that rates good for meagre in winter. Warm-month bites cluster around the evening.

The spring pattern is a shallow one: atlantic mackerel in 5 to 45 ft. Midsummer fish sit out in 15 to 80 ft before dropping to 30 to 120 ft for winter. The spot to know is Sharp break, a drop-off in about 68 ft of water that rates good for atlantic mackerel in summer. Plan around early morning and the evening in the warm months. 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 (19 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 (56 ft) | Compact silver jig, Sparse feather rig |
| Winter | 30 to 120 ft | midday | Sharp break (68 ft) | Small deep jig |
Spring atlantic bonito on Castro Costa hold shallow, usually 15 to 100 ft. Depth-wise the year is flat: 5 to 90 ft in summer, 50 to 220 ft once it turns cold. Put Shoreline point first on the milk run — a point near 19 ft that grades prime for summer. The feeding windows run early morning and the evening.
| Season | Depth | Best window | Start at | Go-to baits |

| Spring | 15 to 100 ft | dawn & dusk | Shoreline point (19 ft) | see map |
| Summer | 5 to 90 ft | dawn & dusk | Shoreline point (19 ft) | see map |

When the water first warms, garfish slide up into 1 to 15 ft. By summer they slide out to 2 to 20 ft, and by winter most fish are in 20 to 60 ft. If you only fish one area, make it Shoreline point: a point around 12 ft that scores prime in spring. In summer the feeding windows fall in 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 | Shoreline point (12 ft) | Slim silver spoon, Small inline spinner |
| Summer | 2 to 20 ft | dawn & dusk | Shoreline point (19 ft) | Slim casting spoon, Surface-skipping fly |
| Fall | 8 to 30 ft | dawn & dusk | Shoreline point (19 ft) | Weighted slim spoon, Small silver jig |
| Winter | 20 to 60 ft | midday | Sharp break (56 ft) |
Castro Costa also holds common sole (3 to 30 ft in summer), thick-lipped grey mullet (1 to 18 ft in summer). Pick any of them on the map above for rated spots and bait picks.
Count 10 structure marks on this chart. The deepest, Deepest basin, sits near 282 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 Castro Costa 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.

Castro Costa is about 282 ft (86 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 Castro Costa. 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 12 ft of water that rates prime for garfish in spring. The interactive chart above rates every spot for each 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 Castro Costa 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.
