20,306-acre Merikarvian avomeri. South 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 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 33 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 8 214 hehtaarin laajuisena, rantaa 49.4 km, ja saaria on 36. Rantaviiva on kohtalaisen rikkonainen (indeksi 1.5). Noin 13% pinnasta on matalampaa kuin ~5 m — siellä ruokaketju elää. Päästä päähän vesi mittaa noin 13.2 km, leveimmillään 9.8 km. Lähin kartoitettu vesi on Porin avomeri - Sector 01, 11.3 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.

Come spring, look for european perch tight to the bank in 1 to 3.5 m. Expect a summer slide to 2.5 to 8.5 m, then a winter hold in 3.5 to 10 m. Start at Weed flat. It's a weed flat holding about 2 m of water and rates prime come spring. Prime time lands in 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 | Sharp break (6 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 | Sharp break (10 m) | Tungsten jig + maggots, Small balance jig |
Early season northern pike use the shallows, holding in 0.5 to 2.5 m. Expect a summer slide to 2.5 to 6 m, then a winter hold in 1.5 to 4.5 m. Put Weed flat first on the milk run — a weed flat near 2 m that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.

|---|---|---|---|---|
| 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 | Sharp break (6 m) | Bucktail, Weedless spoon over cabbage |
| Syksy | 2 to 5.5 m | midday & dawn | Sharp break (4.5 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. By summer they slide out to 4.5 to 15 m, and by winter most fish are in 6 to 18 m. If you only fish one area, make it Sharp break: a drop-off around 15 m that scores good in summer. In summer the feeding windows fall in 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 (3.5 m) | Small herring feather rig, Micro jig rig |

| Talvi | 6 to 18 m | midday | Sharp break (18 m) | Small silver jig, Sparse feather rig |
Start shallow in spring: european whitefish sit in 3 to 12 m that time of year. Warm water sends them out to 8.5 to 24 m; cold water stacks them in 5.5 to 18 m. Top water on the chart: Sharp break, a drop-off in the 10 m range, good in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a small vertical spoon or a micro jig until the fish tell you otherwise.

| Kevät | 3 to 12 m | dawn & dusk | Sharp break (10 m) | Small silver spoon, Micro blade bait |

When the water first warms, sea trout slide up into 1 to 6 m. Summer is a 4.5 to 15 m game here, winter a 1.5 to 9 m one. Start at Rock reef. It's a rock pile holding about 3.5 m of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a deep-running wobbler or a trolled spoon rigged through the warm months.

| Kevät | 1 to 6 m | dawn & dusk | Rock reef (3.5 m) | Slim coastal spoon, Shallow-running wobbler |

| Talvi | 1.5 to 9 m | midday | Rock reef (3.5 m) | Slow coastal spoon, Suspending wobbler |
Spring puts european smelt in skinny water — 1 to 7.5 m is the zone. As the season builds they drop to 7.5 to 21 m, wintering in 6 to 20 m. Fall european smelt concentrate at Sharp break, a good-rated drop-off around 15 m. Warm-month bites cluster around early morning and the evening. A tiny vertical spoon or a micro jig covers the summer program.

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 Merikarvian avomeri - South 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.

Weed flat is the top-rated area: a weed flat in about 6 ft of water that rates prime for european perch in spring. Open the map above to see every rated spot for each species and season.
For european perch, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
