81,271-acre Sejerø Bay. Samsø Side 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. Sejerø Bay. Samsø Side. Western Sejerø Bay around the island approaches, with exposed points, banks and Kattegat exchange. The water tops out around 189 ft. The depth chart comes from Danish Geodata Agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here is how the season plays out for each species, straight from the data behind the map.
On the chart, Sejerø Bay - Samsø Side draws 81,028 acres inside 62.9 miles of shoreline — one island included. The shoreline is moderately structured (index 1.6) — enough points and pockets to pattern. 2% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Call it 23.8 mi long by 9.9 mi wide at the broadest reach. For a second option, Sejerø Bay - Sejerø Island lies 8 mi east.
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.

In spring, sea trout run shallow here, mostly 3 to 20 ft. Summer pushes them deeper, 15 to 50 ft, and winter fish settle into 5 to 30 ft. Time it for early morning and the evening. You won't need more than a deep-running wobbler or a trolled spoon most summer days.
| 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 |
The spring pattern is a shallow one: atlantic herring in 5 to 25 ft. As the season builds they drop to 15 to 50 ft, wintering in 20 to 60 ft. Time it for early morning and the evening. Summer baits: a herring feather rig or a small silver jig gets it done.
| 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 |
When the water first warms, european flounder slide up into 5 to 25 ft. By summer they slide out to 6 to 35 ft, and by winter most fish are in 15 to 50 ft. If you only fish one area, make it Feeding flat: a feeding flat around 44 ft that scores good in fall. In summer the feeding windows fall in early morning and the evening. Keep a bottom jig with spinner blade rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dusk | open water | Small bucktail dragged on bottom |
| Summer | 6 to 35 ft | dawn & dusk | Feeding flat (44 ft) | Bottom jig with spinner blade |
| Fall | 8 to 40 ft | dusk | Feeding flat (44 ft) | Compact bottom jig |
| Winter | 15 to 50 ft | midday | Feeding flat (44 ft) | Small bottom jig |
In spring, garfish run shallow here, mostly 1 to 15 ft. Summer pushes them deeper, 2 to 20 ft, and winter fish settle into 20 to 60 ft. Time it for early morning and the evening. You won't need more than a slim casting spoon or a surface-skipping fly most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 15 ft | dawn & midday | open water | Slim silver spoon, Small inline spinner |

| Winter | 20 to 60 ft | midday | open water |
The spring pattern is a shallow one: european plaice in 8 to 35 ft. Midsummer fish sit out in 6 to 40 ft before dropping to 25 to 80 ft for winter. The spot to know is Feeding flat, a feeding flat in about 44 ft of water that rates good for european plaice in summer. Plan around early morning and the evening in the warm months. Summer baits: a light spooned bottom rig or a beaded trace gets it done.
| Season | Depth | Best window | Start at | Go-to baits |

No official 2025 EEA designated bathing-water point matched within 400 metres of this DDM shoreline. This is an access-evidence gap, not a statement that public fishing access does not exist. Verify land ownership, local signs, conservation belts 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 Denmark waters are set by the Danish Agency for Green Transition and Aquatic Environment (current recreational fishing rules) — and special regulations can apply to Sejerø Bay - Samsø Side specifically, so confirm the current rules before you fish. Most anglers using light hand gear need the applicable Danish angling licence, subject to the official age exemptions. Check live species rules, the mapped and unmapped 500-metre stream-mouth conservation belts, local fishing rights, protected areas and posted shore access before every trip. Recreational European eel fishing is currently prohibited, so eel is not promoted as a target here.

Feeding flat is the top-rated area: a feeding flat in about 44 ft of water that rates good for european plaice in summer. Every other rated spot, per species and season, is on the map above.
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.
