61,028-acre Great Belt. Langeland Southeast 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 southeastern Langeland reach toward the western Baltic, with measured banks, reefs and exposed current lines. The water tops out around 180 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.
Drawn out, this is 61,041 acres of water rimmed by 76.9 miles of bank, broken up by 4 islands. An index of 2.2 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. The shallow band under 15 ft claims about 29% of the surface — that's where the groceries are. Figure 13.1 mi of water from one end to the other, 13.1 mi at the beam. The nearest mapped water is Great Belt - Langeland Northeast, 12 mi to the north.
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.

The spring pattern is a shallow one: sea trout in 3 to 20 ft. As the season builds they drop to 15 to 50 ft, wintering in 5 to 30 ft. Top water on the chart: DDM source-backed depth reference (54 ft), a point in the 54 ft range, good in summer. Time it for early morning and the evening. 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 |
| Summer | 15 to 50 ft | dawn & dusk | DDM source-backed depth reference (54 ft) (54 ft) | 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 |
In spring, atlantic herring run shallow here, mostly 5 to 25 ft. Summer pushes them deeper, 15 to 50 ft, and winter fish settle into 20 to 60 ft. DDM source-backed depth reference (25 ft) is the standout, a feeding flat at roughly 25 ft, rated good for spring atlantic herring. Time it for early morning and the evening. 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 | DDM source-backed depth reference (25 ft) (25 ft) | 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. Expect a summer slide to 6 to 35 ft, then a winter hold in 15 to 50 ft. Put DDM source-backed depth reference (25 ft) first on the milk run — a feeding flat near 25 ft that grades prime for spring. In summer the feeding windows fall in 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 | DDM source-backed depth reference (25 ft) (25 ft) | Small bucktail dragged on bottom |
| Summer | 6 to 35 ft | dawn & dusk | DDM source-backed depth reference (25 ft) (25 ft) | Bottom jig with spinner blade |
| Fall | 8 to 40 ft | dusk | DDM source-backed depth reference (25 ft) (25 ft) | Compact bottom jig |
| Winter | 15 to 50 ft | midday | DDM source-backed depth reference (25 ft) (25 ft) | Small bottom jig |
The spring pattern is a shallow one: garfish in 1 to 15 ft. As the season builds they drop to 2 to 20 ft, wintering in 20 to 60 ft. Time it for early morning and the evening. Summer baits: a slim casting spoon or a surface-skipping fly gets it done.
| 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 |
Spring puts european plaice in skinny water — 8 to 35 ft is the zone. Warm water sends them out to 6 to 40 ft; cold water stacks them in 25 to 80 ft. DDM source-backed depth reference (25 ft) is the standout, a feeding flat at roughly 25 ft, rated prime for spring european plaice. Plan around early morning and the evening in the warm months. A light spooned bottom rig or a beaded trace covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 35 ft | dusk | DDM source-backed depth reference (25 ft) (25 ft) | Beaded flowing trace |
| Summer | 6 to 40 ft | dawn & dusk | DDM source-backed depth reference (25 ft) (25 ft) | Light spooned bottom rig, Beaded trace |
| Fall | 10 to 50 ft | dusk | DDM source-backed depth reference (25 ft) (25 ft) | Beaded bottom trace |
| Winter | 25 to 80 ft | midday | DDM source-backed depth reference (90 ft) (90 ft) |
Spring puts whiting in skinny water — 15 to 55 ft is the zone. Warm water sends them out to 20 to 70 ft; cold water stacks them in 15 to 70 ft. DDM source-backed depth reference (77 ft) is the standout, a current seam at roughly 77 ft, rated good for summer whiting. Plan around early morning in the warm months. A small vertical jig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 55 ft | dawn & dusk | open water | Small silver jig, Two-hook feather rig |
| Summer | 20 to 70 ft | dawn | DDM source-backed depth reference (77 ft) (77 ft) | Small vertical jig |
| Fall | 10 to 60 ft | dusk | open water | Small silver jig, Sparse feather rig |
| Winter | 15 to 70 ft | dusk | open water | Compact vertical jig |

Great Belt - Langeland Southeast is about 180 ft (55 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 - Langeland Southeast. 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 (25 ft) is the top-rated area: a feeding flat in about 25 ft of water that rates prime for european flounder in spring. The interactive chart above rates every spot for each 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.
