15,995-acre Mosshaga-Algersö. North 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 42 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.
Kartalla Mosshaga-Algersö - North kattaa 6 474 hehtaaria, rantaviivaa 148.1 km, ja saaria on 309. Rantaviiva on voimakkaasti rikkonainen (indeksi 5.2) — lahtia ja niemiä kaikkialla, mikä moninkertaistaa kalastettavan reunan. Noin 20% pinnasta on matalampaa kuin ~5 m — siellä ruokaketju elää. Päästä päähän vesi mittaa noin 14.8 km, leveimmillään 10 km. Lähin kartoitettu vesi on Mosshaga-Algersö - South, 9.7 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.

Spring puts european perch in skinny water — 1 to 3.5 m is the zone. Warm water sends them out to 2.5 to 8.5 m; cold water stacks them in 3.5 to 10 m. Weed flat is the standout, a weed flat at roughly 2.5 m, rated prime for spring european perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small crankbait (perch pattern) covers the summer program.
| 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 | 2.5 to 8.5 m | dawn | Sharp break (6.5 m) | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Syksy | 3 to 10 m | midday | Sharp break (6.5 m) | Jigging spoon (small), Drop-shot on deep flats |
| Talvi | 3.5 to 10 m | midday & dawn | Offshore hump (6 m) | Tungsten jig + maggots, Small balance jig |
Spring puts zander in skinny water — 1 to 4.5 m is the zone. Warm water sends them out to 4.5 to 11 m; cold water stacks them in 6 to 12 m. Offshore hump is the standout, an offshore hump at roughly 6 m, rated prime for summer zander. Plan around the evening and early morning in the warm months. A vertical softbait over humps or a deep crankbait covers the summer program.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 1 to 4.5 m | dusk & dawn | Rock reef (2.5 m) | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |
| Kesä | 4.5 to 11 m | dusk & dawn | Offshore hump (6 m) | Vertical softbait over humps, Deep crankbait |
| Syksy | 3.5 to 12 m | dusk & night | Sharp break (6.5 m) | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Talvi | 6 to 12 m | dusk & dawn | Offshore hump (6 m) | Slow blade bait |
Spring puts northern pike in skinny water — 0.5 to 2.5 m is the zone. As the season builds they drop to 2.5 to 6 m, wintering in 1.5 to 4.5 m. Spring northern pike concentrate at Weed flat, a prime-rated weed flat around 0.5 m. Warm-month bites cluster around early morning and the evening. A bucktail or a weedless spoon over cabbage covers the summer program.
| Kausi | Syvyys | Paras aika | Aloita | Vieheet |
|---|---|---|---|---|
| Kevät | 0.5 to 2.5 m | midday & dawn | Weed flat (0.5 m) | #5 inline spinner, Spoon (red/white) |
| Kesä | 2.5 to 6 m | dawn & dusk | Weed flat (2.5 m) | Bucktail, Weedless spoon over cabbage |
| Syksy | 2 to 5.5 m | midday & dawn | Sharp break (2 m) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Talvi | 1.5 to 4.5 m | midday | Weed flat (2.5 m) | Large jigging spoon |
In spring, atlantic herring run shallow here, mostly 1.5 to 7.5 m. Midsummer fish sit out in 4.5 to 15 m before dropping to 6 to 18 m for winter. Summer atlantic herring concentrate at Sharp break, a good-rated drop-off around 6.5 m. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a herring feather rig or a small silver jig most summer days.

|---|---|---|---|---|
| Kevät | 1.5 to 7.5 m | dawn & dusk | Rock reef (2.5 m) | Small herring feather rig, Micro jig rig |
| Kesä | 4.5 to 15 m | dawn & dusk | Sharp break (6.5 m) | Herring feather rig, Small silver jig |
| Syksy | 3 to 12 m | dawn & dusk | Sharp break (6.5 m) | Small feather rig, Compact silver spoon |
| Talvi | 6 to 18 m | midday | Sharp break (18 m) | Small silver jig, Sparse feather rig |
Come spring, look for european whitefish tight to the bank in 3 to 12 m. They move out to 8.5 to 24 m in summer and finish the year down in 5.5 to 18 m. If you only fish one area, make it Sharp break: a drop-off around 6.5 m that scores good in spring. Best bite is early morning and the evening. A small vertical spoon or a micro jig is the honest summer answer here.

| Kevät | 3 to 12 m | dawn & dusk | Sharp break (6.5 m) | Small silver spoon, Micro blade bait |

| Talvi | 5.5 to 18 m | midday | Offshore hump (6 m) | Small jigging spoon |
Early season european flounder use the shallows, holding in 1.5 to 7.5 m. Summer is a 2 to 11 m game here, winter a 4.5 to 15 m one. The chart's best answer is Sharp break — drop-off, 6.5 m, prime for fall. Best bite is early morning and the evening. Tie on a bottom jig with spinner blade and you're in the game.

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 Mosshaga-Algersö - North 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.
