7,703-acre Olkijoki - Siikajoki - Säärenperä. Central 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 Bothnian Bay. 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 5.5 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 rest of this page walks each species through its year, using the map's own scoring.
Vesi piirtyy 3 116 hehtaarin laajuisena, rantaa 57.6 km, ja saaria on 6. Rantaviiva on voimakkaasti rikkonainen (indeksi 2.9) — lahtia ja niemiä kaikkialla, mikä moninkertaistaa kalastettavan reunan. Noin 98% pinnasta on matalampaa kuin ~5 m — siellä ruokaketju elää. Päästä päähän vesi mittaa noin 14.2 km, leveimmillään 7.2 km. Lähin kartoitettu vesi on Raahe - Hailuoto - Sector 06, 4.8 km lounaaseen.

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.

Spring european perch on Olkijoki - Siikajoki - Säärenperä - Central West hold shallow, usually 1 to 3.5 m. They move out to 1.5 to 5.5 m in summer and finish the year down in 1.5 to 5.5 m. Put Weed flat first on the milk run — a weed flat near 2.5 m that grades prime for spring. The feeding windows run early morning. The summer box starts with a drop-shot micro plastics or a small crankbait (perch pattern).
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 3.5 m | midday & dawn | Weed flat (2.5 m) | Small jig + curly tail, Inline spinner #1-2 |
| Kesä | 1.5 to 5.5 m | dawn | Deepest basin (5.5 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |

| Talvi | 1.5 to 5.5 m | midday & dawn | Deepest basin (5.5 m) | Tungsten jig + maggots, Small balance jig |
When the water first warms, northern pike slide up into 0.5 to 2.5 m. Summer is a 1.5 to 5.5 m game here, winter a 1.5 to 4.5 m one. Start at Weed flat. It's a weed flat holding about 2.5 m of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.

Early season atlantic herring use the shallows, holding in 1 to 5.5 m. Even in summer they hold at 1.5 to 5.5 m; winter keeps them in 1.5 to 5.5 m. The chart's best answer is Deepest basin — deep basin, 5.5 m, prime for summer. Best bite is early morning and the evening. Tie on a herring feather rig or a small silver jig and you're in the game.

In spring, european whitefish run shallow here, mostly 1.5 to 5.5 m. Summer keeps them at 1.5 to 5.5 m, and they winter in 1.5 to 5.5 m. Deepest basin is the standout, a deep basin at roughly 5.5 m, rated prime for spring european whitefish. Time it for early morning and the evening. You won't need more than a small vertical spoon or a micro jig most summer days.

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 Olkijoki - Siikajoki - Säärenperä - Central 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.
