117,356-acre Sejerø Bay. Middle 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. Middle. Eastern Sejerø Bay along the Odsherred shore, with headlands, reefs and broad sand-bottom transitions. The water tops out around 156 ft. The depth chart comes from Danish Geodata Agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Below is the species-by-species picture, pulled from the same data the map uses.
On the chart, Sejerø Bay - Middle draws 117,572 acres inside 79 miles of shoreline. The shoreline is moderately structured (index 1.6) — enough points and pockets to pattern. About 4% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. End to end it runs roughly 24.3 mi, about 14.8 mi across. The nearest mapped water is Sejerø Bay - Sejerø Island, 8 mi to the west.
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.

Spring puts sea trout in skinny water — 3 to 20 ft is the zone. Warm water sends them out to 15 to 50 ft; cold water stacks them in 5 to 30 ft. Shoreline point is the standout, a point at roughly 33 ft, rated good for winter sea trout. Plan around early morning and the evening in the warm months. A deep-running wobbler or a trolled spoon covers the summer program.
| 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 | Shoreline point (33 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 | Shoreline point (33 ft) | Slow coastal spoon, Suspending wobbler |
Start shallow in spring: atlantic herring sit in 5 to 25 ft that time of year. Warm water sends them out to 15 to 50 ft; cold water stacks them in 20 to 60 ft. Fish it in early morning and the evening and you'll meet the bite. Throw a herring feather rig or a small silver jig until the fish tell you otherwise.
| 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 |
Come spring, look for european flounder tight to the bank in 5 to 25 ft. They move out to 6 to 35 ft in summer and finish the year down in 15 to 50 ft. If you only fish one area, make it Feeding flat: a feeding flat around 38 ft that scores good in fall. Best bite is early morning and the evening. A bottom jig with spinner blade is the honest summer answer here.
| 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 (38 ft) | Bottom jig with spinner blade |
| Fall | 8 to 40 ft | dusk | Feeding flat (38 ft) | Compact bottom jig |
| Winter | 15 to 50 ft | midday | DDM measured creek channel (51 ft) | Small bottom jig |
Spring puts garfish in skinny water — 1 to 15 ft is the zone. Warm water sends them out to 2 to 20 ft; cold water stacks them in 20 to 60 ft. DDM measured current seam is the standout, a current seam at roughly 61 ft, rated good for winter garfish. Plan around early morning and the evening in the warm months. A slim casting spoon or a surface-skipping fly covers the summer program.
| 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 | DDM measured current seam (61 ft) |
Start shallow in spring: european plaice sit in 8 to 35 ft that time of year. Summer pushes them deeper, 6 to 40 ft, and winter fish settle into 25 to 80 ft. The spot to know is Feeding flat, a feeding flat in about 38 ft of water that rates prime for european plaice in summer. Warm-month bites cluster around early morning and the evening. Throw a light spooned bottom rig or a beaded trace until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 35 ft | dusk | DDM measured shoal (31 ft) | Beaded flowing trace |
| Summer | 6 to 40 ft | dawn & dusk | Feeding flat (38 ft) | Light spooned bottom rig, Beaded trace |
| Fall | 10 to 50 ft | dusk | Feeding flat (38 ft) | Beaded bottom trace |
| Winter | 25 to 80 ft | midday | DDM measured channel edge (72 ft) |
Start shallow in spring: whiting sit in 15 to 55 ft that time of year. Summer pushes them deeper, 20 to 70 ft, and winter fish settle into 15 to 70 ft. The spot to know is DDM measured channel edge, a channel edge in about 72 ft of water that rates good for whiting in winter. Warm-month bites cluster around early morning. Throw a small vertical jig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 55 ft | dawn & dusk | DDM measured channel edge (72 ft) | Small silver jig, Two-hook feather rig |
| Summer | 20 to 70 ft | dawn | DDM measured channel edge (72 ft) | Small vertical jig |
| Fall | 10 to 60 ft | dusk | DDM measured current seam (61 ft) | Small silver jig, Sparse feather rig |
| Winter | 15 to 70 ft | dusk | DDM measured channel edge (72 ft) | Compact vertical jig |

Access data: European Environment Agency — 2025 Bathing Water Directive Sites (Denmark). Confirm conditions and fees locally before you launch.
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 - Middle 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.

Sejerø Bay - Middle is about 156 ft (48 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, thick-lipped grey mullet, brill, saithe (coalfish) roster for Sejerø Bay - Middle. 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.
Feeding flat is the top-rated area: a feeding flat in about 38 ft of water that rates prime for european plaice 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.
