49,886-acre Korppoon - Houtskarin ulkosaaristoalue. Sector 12 Finland coastal fishing map with an exact official national water-body boundary, EMODnet 2024 official Finnish hydrographic chart/DTM assessed contours, source-assessed fishing spots, official regional fish evidence, seasonal forage guidance, public-access review and current-rule links. Official Syke VHS 2022 named coastal water in Archipelago Sea. 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 129 m. The depth chart comes from EMODnet, with national hydrographic source-reference audit official hydrographic-chart depth models, so the contours are chart-derived rather than computer-modeled; no directly measured sounding coverage is claimed. The season-by-season read for each species follows, from the map's own numbers.
Vesi piirtyy 20 160 hehtaarin laajuisena, rantaa 97.5 km, ja saaria on 179. Rantaviiva on kohtalaisen rikkonainen (indeksi 1.9). Noin 2% pinnasta on matalampaa kuin ~5 m — siellä ruokaketju elää. Päästä päähän vesi mittaa noin 16.6 km, leveimmillään 16.1 km. Lähin kartoitettu vesi on Korppoon - Houtskarin ulkosaaristoalue - Sector 11, 8 km länteen.

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 perch tight to the bank in 1 to 3.5 m. They move out to 2.5 to 8.5 m in summer and finish the year down in 3.5 to 10 m. If you only fish one area, make it Weed flat: a weed flat around 2 m that scores prime in spring. Best bite is early morning. A drop-shot micro plastics or a small crankbait (perch pattern) is the honest summer answer here.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 3.5 m | midday & dawn | Weed flat (2 m) | Small jig + curly tail, Inline spinner #1-2 |
| Kesä | 2.5 to 8.5 m | dawn | Offshore hump (6.5 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Syksy | 3 to 10 m | midday | Offshore hump (6.5 m) | Jigging spoon (small), Drop-shot on deep flats |
| Talvi | 3.5 to 10 m | midday & dawn | Offshore hump (6.5 m) | Tungsten jig + maggots, Small balance jig |
Come spring, look for zander tight to the bank in 1 to 4.5 m. They move out to 4.5 to 11 m in summer and finish the year down in 6 to 12 m. If you only fish one area, make it Offshore hump: an offshore hump around 6.5 m that scores prime in summer. Best bite is the evening and early morning. A vertical softbait over humps or a deep crankbait is the honest summer answer here.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 4.5 m | dusk & dawn | Rock reef (4 m) | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |
| Kesä | 4.5 to 11 m | dusk & dawn | Offshore hump (6.5 m) | Vertical softbait over humps, Deep crankbait |
| Syksy | 3.5 to 12 m | dusk & night | Shoreline point (10 m) | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Talvi | 6 to 12 m | dusk & dawn | Offshore hump (6.5 m) | Slow blade bait |
Early season northern pike use the shallows, holding in 0.5 to 2.5 m. Summer is a 2.5 to 6 m game here, winter a 1.5 to 4.5 m one. The chart's best answer is Weed flat — weed flat, 2 m, prime for spring. Best bite is early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 0.5 to 2.5 m | midday & dawn | Weed flat (2 m) | #5 inline spinner, Spoon (red/white) |
| Kesä | 2.5 to 6 m | dawn & dusk | Weed flat (2 m) | Bucktail, Weedless spoon over cabbage |
| Syksy | 2 to 5.5 m | midday & dawn | Weed flat (2 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Talvi | 1.5 to 4.5 m | midday | Weed flat (2 m) | Large jigging spoon |
When the water first warms, atlantic herring slide up into 1.5 to 7.5 m. Summer is a 4.5 to 15 m game here, winter a 6 to 18 m one. Start at Rock reef. It's a rock pile holding about 4 m of water and rates good come spring. The feeding windows run early morning and the evening. Keep a herring feather rig or a small silver jig rigged through the warm months.

| Kevät | 1.5 to 7.5 m | dawn & dusk | Rock reef (4 m) | Small herring feather rig, Micro jig rig |

| Syksy | 3 to 12 m | dawn & dusk | open water | Small feather rig, Compact silver spoon |
| Talvi | 6 to 18 m | midday | open water | Small silver jig, Sparse feather rig |
Start shallow in spring: european whitefish sit in 3 to 12 m that time of year. Summer pushes them deeper, 8.5 to 24 m, and winter fish settle into 5.5 to 18 m. The spot to know is Rock reef, a rock pile in about 4 m of water that rates good for european whitefish in fall. Warm-month bites cluster around early morning and the evening. Throw a small vertical spoon or a micro jig until the fish tell you otherwise.

| Talvi | 5.5 to 18 m | midday | Offshore hump (6.5 m) | Small jigging spoon |
The spring pattern is a shallow one: european flounder in 1.5 to 7.5 m. Midsummer fish sit out in 2 to 11 m before dropping to 4.5 to 15 m for winter. Plan around early morning and the evening in the warm months. Summer baits: a bottom jig with spinner blade gets it done.

No active municipality-, consortium-, or state-owned LIPAS fishing, boating, beach, swimming, canoe or motor-boat facility matched within 400 metres of this exact mapped shoreline. This is an access-evidence gap, not a claim that public access does not exist. Verify land ownership, 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 Finland waters are set by the Kalastusrajoitus.fi (official current Finnish fishing-restriction service) — and special regulations can apply to Korppoon - Houtskarin ulkosaaristoalue - Sector 12 specifically, so confirm the current rules before you fish. Check Kalastusrajoitus.fi, current protection periods and permit requirements before every Finnish coastal trip. Local no-fishing areas, river-mouth restrictions, protected species, minimum sizes, seasonal closures, gear rules, the fisheries-management fee and water-owner permissions may apply. A mapped hydrographic contour, fishing-spot marker or nearby LIPAS public facility is planning context only and never grants fishing, retention, shoreline entry, parking, launching or safe-navigation permission.
