3734-acre Inner Gdansk Bay. Sector 04 Poland coastal fishing map with an exact official national water-body boundary, EMODnet 2024 official Polish POL200M/POL500M hydrographic DTM / traceable CDI assessed contours, source-assessed fishing spots, official regional fish evidence, seasonal forage guidance, public-access review and current-rule links. Official Polish WFD named coastal or transitional assessment water in Polish Lagoons and Estuaries. 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 231 ft. 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. Here is how the season plays out for each species, straight from the data behind the map.
Drawn out, this is 3,734 acres of water rimmed by 14.5 miles of bank. Index 1.7 on the shoreline: a few honest points and pockets, nothing labyrinthine. The shallow band under 15 ft claims about 1% of the surface — that's where the groceries are. The basin spans about 6.1 mi end to end and 1.9 mi across at its widest. The nearest mapped water is Inner Gdansk Bay - Sector 08, 4 mi to the southeast.
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 — 3 to 12 ft is the zone. Warm water sends them out to 8 to 28 ft; cold water stacks them in 12 to 33 ft. Plan around early morning in the warm months. A drop-shot micro plastics or a small crankbait (perch pattern) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | open water | Small jig + curly tail, Inline spinner #1-2 |
| Summer | 8 to 28 ft | dawn | open water | Drop-shot micro plastics, Small crankbait (perch pattern) |
| Fall | 10 to 33 ft | midday | open water | Jigging spoon (small), Drop-shot on deep flats |
| Winter | 12 to 33 ft | midday & dawn | open water | Tungsten jig + maggots, Small balance jig |
Spring puts northern pike in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 8 to 20 ft, wintering in 5 to 15 ft. Warm-month bites cluster around early morning and the evening. A bucktail or a weedless spoon over cabbage covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |

| Winter | 5 to 15 ft | midday | open water | Large jigging spoon |
Spring puts zander in skinny water — 4 to 15 ft is the zone. Warm water sends them out to 15 to 35 ft; cold water stacks them in 20 to 40 ft. Plan around the evening and early morning in the warm months. A vertical softbait over humps or a deep crankbait covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | open water | Softbait on jighead (10-12 cm), Shallow crankbait at dusk |

| Fall | 12 to 40 ft | dusk & night | open water | Big softbait (12-16 cm) slow-rolled, Jigging spoon |
| Winter | 20 to 40 ft | dusk & dawn | open water | Slow blade bait |
In spring, atlantic herring run shallow here, mostly 5 to 25 ft. Midsummer fish sit out in 15 to 50 ft before dropping to 20 to 60 ft for winter. 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | open water | Small herring feather rig, Micro jig rig |
| Summer | 15 to 50 ft | dawn & dusk | open water | Herring feather rig, Small silver jig |
| Fall | 10 to 40 ft | dawn & dusk | open water | Small feather rig, Compact silver spoon |
| Winter | 20 to 60 ft | midday | open water | Small silver jig, Sparse feather rig |
Early season european flounder use the shallows, holding in 5 to 25 ft. Summer is a 6 to 35 ft game here, winter a 15 to 50 ft one. Best bite is early morning and the evening. Tie on a bottom jig with spinner blade and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dusk | open water | Small bucktail dragged on bottom |

The spring pattern is a shallow one: sea trout in 3 to 20 ft. Midsummer fish sit out in 15 to 50 ft before dropping to 5 to 30 ft for winter. Plan around early morning and the evening in the warm months. Summer baits: a deep-running wobbler or a trolled spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 20 ft | dawn & dusk | open water | Slim coastal spoon, Shallow-running wobbler |

Polish maritime administration ports and harbours review was reviewed, but no stable government record establishes a public fishing entrance, parking or launch for this exact mapped child. This is an access-evidence gap, not a claim that public access does not exist. Verify land ownership, port and harbour rules, protected areas, 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 Poland waters are set by the Polish Ministry of Agriculture and Rural Development (current recreational marine-fishing rules) — and special regulations can apply to Inner Gdansk Bay - Sector 04 specifically, so confirm the current rules before you fish. Check Poland's live national and EU Baltic recreational-fishing rules before every trip. Fees, permitted methods, protected sizes and periods, species prohibitions, harbour spinning closures, marine protected areas and local port or shoreline directions can change. Directed recreational retention of cod, eel and some salmon is restricted or prohibited under the cited framework; never infer an open fishery from a regional occurrence roster. An official DTM contour, fishing spot or nearby port reference is planning context only and never grants fishing, retention, access, parking, launching, port-entry or safe-navigation permission.

Inner Gdansk Bay - Sector 04 is about 231 ft (70 m) deep at its deepest point. 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.
