18,838-acre Koxnan. North West 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 Åland 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 64 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. What the data behind the map says about each species, season by season:
Kartalla Koxnan - North West kattaa 7 619 hehtaaria, rantaviivaa 38.1 km. Allas on yksinkertainen (rantaindeksi 1.2) — lähes malja, joten syvyyskäyrät merkitsevät enemmän kuin ranta. Noin 0% pinnasta on matalampaa kuin ~5 m — siellä ruokaketju elää. Päästä päähän vesi mittaa noin 14 km, leveimmillään 8.4 km. Lähin kartoitettu vesi on Koxnan - Central West, 6.4 km etelään.

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.

Start shallow in spring: european perch sit in 1 to 3.5 m that time of year. Summer pushes them deeper, 2.5 to 8.5 m, and winter fish settle into 3.5 to 10 m. The spot to know is Sharp break, a drop-off in about 10 m of water that rates good for european perch in fall. Warm-month bites cluster around early morning. Throw a drop-shot micro plastics or a small crankbait (perch pattern) until the fish tell you otherwise.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 3.5 m | midday & dawn | open water | Small jig + curly tail, Inline spinner #1-2 |
| Kesä | 2.5 to 8.5 m | dawn | Sharp break (10 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Syksy | 3 to 10 m | midday | Sharp break (10 m) | Jigging spoon (small), Drop-shot on deep flats |
| Talvi | 3.5 to 10 m | midday & dawn | Offshore hump (10 m) | Tungsten jig + maggots, Small balance jig |
Start shallow in spring: zander sit in 1 to 4.5 m that time of year. Summer pushes them deeper, 4.5 to 11 m, and winter fish settle into 6 to 12 m. The spot to know is Offshore hump, an offshore hump in about 10 m of water that rates prime for zander in summer. Warm-month bites cluster around the evening and early morning. Throw a vertical softbait over humps or a deep crankbait until the fish tell you otherwise.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 4.5 m | dusk & dawn | open water | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |

| Talvi | 6 to 12 m | dusk & dawn | Offshore hump (10 m) | Slow blade bait |
The spring pattern is a shallow one: northern pike in 0.5 to 2.5 m. Midsummer fish sit out in 2.5 to 6 m before dropping to 1.5 to 4.5 m for winter. Plan around early morning and the evening in the warm months. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.

The spring pattern is a shallow one: atlantic herring in 1.5 to 7.5 m. As the season builds they drop to 4.5 to 15 m, wintering in 6 to 18 m. Top water on the chart: Sharp break, a drop-off in the 10 m range, good in summer. Time it for early morning and the evening. Summer baits: a herring feather rig or a small silver jig gets it done.

Spring european whitefish on Koxnan - North West hold shallow, usually 3 to 12 m. By summer they slide out to 8.5 to 24 m, and by winter most fish are in 5.5 to 18 m. The chart's best answer is Sharp break — drop-off, 10 m, good for spring. Prime time lands in early morning and the evening. The summer box starts with a small vertical spoon or a micro jig.

When the water first warms, european flounder slide up into 1.5 to 7.5 m. By summer they slide out to 2 to 11 m, and by winter most fish are in 4.5 to 15 m. If you only fish one area, make it Sharp break: a drop-off around 10 m that scores prime in fall. In summer the feeding windows fall in early morning and the evening. Keep a bottom jig with spinner blade rigged through the warm months.

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 Koxnan - North West 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.
