169,114-acre Great Belt. Smålandsfarvandet Denmark saltwater fishing map with official Danish Geodata Agency 50 m bathymetry, measured-only fishing spots, DTU-supported fish targets, seasonal forage guidance and public shore-access context. The southern-central Great Belt and Smålandsfarvandet transition, with islands, shoals and measured channel edges. The water tops out around 228 ft. The depth chart comes from Danish Geodata Agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 169,096 acres wrapped in 108.4 miles of bank, with a single island in the mix. A middling shoreline index (1.9) gives it some bays to work without being a maze. Roughly 11% of the water is 15 ft or less, the band where the food chain lives. Figure 19.4 mi of water from one end to the other, 18.2 mi at the beam. Great Belt - Langeland Northeast sits 14 mi south — the closest neighbouring chart.
The target roster combines the named DTU monitoring area with conservative habitat-compatible Danish regional records. It documents observed or regionally supported occurrence, not equal abundance, a catch rate, or a promised catch in this child. European eel is omitted because recreational eel fishing is currently closed. 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.

When the water first warms, sea trout slide up into 3 to 20 ft. Summer is a 15 to 50 ft game here, winter a 5 to 30 ft one. The feeding windows run early morning and the evening. Keep a deep-running wobbler or a trolled spoon rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 20 ft | dawn & dusk | open water | Slim coastal spoon, Shallow-running wobbler |
| Summer | 15 to 50 ft | dawn & dusk | open water | Deep-running wobbler, Trolled spoon |
| Fall | 3 to 25 ft | dawn & dusk | open water | Coastal wobbler, Casting spoon |
| Winter | 5 to 30 ft | midday | open water | Slow coastal spoon, Suspending wobbler |
When the water first warms, atlantic herring slide up into 5 to 25 ft. By summer they slide out to 15 to 50 ft, and by winter most fish are in 20 to 60 ft. 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.
| 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 |
The spring pattern is a shallow one: european flounder in 5 to 25 ft. As the season builds they drop to 6 to 35 ft, wintering in 15 to 50 ft. Top water on the chart: DDM source-backed depth reference (27 ft), a feeding flat in the 27 ft range, prime in summer. Time it for early morning and the evening. Summer baits: a bottom jig with spinner blade gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dusk | DDM source-backed depth reference (27 ft) (27 ft) | Small bucktail dragged on bottom |
| Summer | 6 to 35 ft | dawn & dusk | DDM source-backed depth reference (27 ft) (27 ft) | Bottom jig with spinner blade |
| Fall | 8 to 40 ft | dusk | DDM source-backed depth reference (27 ft) (27 ft) | Compact bottom jig |
| Winter | 15 to 50 ft | midday | DDM source-backed depth reference (27 ft) (27 ft) | Small bottom jig |
When the water first warms, garfish slide up into 1 to 15 ft. Summer is a 2 to 20 ft game here, winter a 20 to 60 ft one. The feeding windows run early morning and the evening. Keep a slim casting spoon or a surface-skipping fly rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 15 ft | dawn & midday | open water | Slim silver spoon, Small inline spinner |
| Summer | 2 to 20 ft | dawn & dusk | open water | Slim casting spoon, Surface-skipping fly |
| Fall | 8 to 30 ft | dawn & dusk | open water | Weighted slim spoon, Small silver jig |
| Winter | 20 to 60 ft | midday | open water |
Early season european plaice use the shallows, holding in 8 to 35 ft. Expect a summer slide to 6 to 40 ft, then a winter hold in 25 to 80 ft. Put DDM source-backed depth reference (27 ft) first on the milk run — a feeding flat near 27 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a light spooned bottom rig or a beaded trace and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 35 ft | dusk | DDM source-backed depth reference (27 ft) (27 ft) | Beaded flowing trace |
| Summer | 6 to 40 ft | dawn & dusk | DDM source-backed depth reference (27 ft) (27 ft) | Light spooned bottom rig, Beaded trace |
| Fall | 10 to 50 ft | dusk | DDM source-backed depth reference (27 ft) (27 ft) | Beaded bottom trace |
| Winter | 25 to 80 ft | midday | open water |
Early season whiting use the shallows, holding in 15 to 55 ft. Expect a summer slide to 20 to 70 ft, then a winter hold in 15 to 70 ft. In summer the feeding windows fall in early morning. Tie on a small vertical jig and you're in the game.

Great Belt - Smålandsfarvandet is about 228 ft (69 m) deep at its deepest point. The depth chart comes from Danish Geodata Agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Official coastal monitoring from DTU Aqua key-fisher monitoring, 2020–2022 informs the sea trout, atlantic herring, european flounder, garfish, european plaice, whiting, atlantic mackerel, common sole roster for Great Belt - Smålandsfarvandet. The mixed roster combines exact-water records where available with habitat-filtered regional evidence; not every species is documented at this exact water, and it is not a promise of equal abundance or a catch on a particular trip.
DDM source-backed depth reference (27 ft) is the top-rated area: a feeding flat in about 27 ft of water that rates prime for european flounder in summer. Scroll up to the map for the complete spot list by species and season.
For sea trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
