4499-acre Nerbioi / Nervión Exterior Transición 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 112 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 4,500 acres wrapped in 20.6 miles of bank. That shoreline is heavily fingered (development index 2.2) — bays, points and pockets everywhere, which multiplies the fishable edge. The shallow band under 15 ft claims about 14% of the surface — that's where the groceries are. The basin spans about 5.2 mi end to end and 2.4 mi across at its widest. If the bite dies, Cantabria-Matxitxako - West is 4 mi to the north.
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.

Early season european seabass use the shallows, holding in 3 to 25 ft. Summer is a 2 to 30 ft game here, winter a 10 to 55 ft one. The chart's best answer is Shoreline point — point, 14 ft, good for fall. Best bite is early morning and the evening. Tie on a surface lure or a paddle-tail soft plastic and you're in the game.
| 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 |
In spring, gilthead seabream run shallow here, mostly 3 to 35 ft. Midsummer fish sit out in 2 to 45 ft before dropping to 20 to 100 ft for winter. Winter gilthead seabream concentrate at Deepest basin, a good-rated deep basin around 109 ft. Fish it in early morning and the evening and you'll meet the bite.

In spring, meagre run shallow here, mostly 12 to 80 ft. Summer pushes them deeper, 8 to 100 ft, and winter fish settle into 25 to 112 ft. Deepest basin is the standout, a deep basin at roughly 109 ft, rated prime for winter meagre. Time it for the evening.

In spring, atlantic mackerel run shallow here, mostly 5 to 45 ft. Midsummer fish sit out in 15 to 80 ft before dropping to 28 to 112 ft for winter. Winter atlantic mackerel concentrate at Deepest basin, a prime-rated deep basin around 109 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a feather rig or a small vertical jig most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 45 ft | dawn & dusk | Shoreline point (14 ft) | Mackerel feather rig, Small silver jig |
| Summer | 15 to 80 ft | dawn & dusk | Sharp break (42 ft) | Feather rig, Small vertical jig |
| Fall | 10 to 65 ft | dawn & dusk | Sharp break (42 ft) | Compact silver jig, Sparse feather rig |
| Winter | 28 to 112 ft | midday | Deepest basin (109 ft) | Small deep jig |
Come spring, look for atlantic bonito tight to the bank in 15 to 100 ft. Through summer count on 5 to 90 ft; the winter hold is 25 to 112 ft. If you only fish one area, make it Deepest basin: a deep basin around 109 ft that scores prime in winter. 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 (14 ft) | see map |
| Summer | 5 to 90 ft | dawn & dusk | Shoreline point (14 ft) | see map |

Spring garfish on Nerbioi / Nervión Exterior Transición hold shallow, usually 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. The chart's best answer is Shoreline point — point, 14 ft, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a slim casting spoon or a surface-skipping fly.
| 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 | Sharp break (42 ft) |
Nerbioi / Nervión Exterior Transición 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 5 structure marks on this chart. The deepest, Deepest basin, sits near 109 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 Nerbioi / Nervión Exterior Transición 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.

Nerbioi / Nervión Exterior Transición is about 112 ft (34 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 Nerbioi / Nervión Exterior Transición. 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.
Deepest basin is the top-rated area: a deep basin in about 109 ft of water that rates prime for meagre in winter. Every other rated spot, per species and season, is on the map above.
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 Nerbioi / Nervión Exterior Transición 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.
