45,948-acre Trondheimsfjord. Outer Norway saltwater fishing map with official Kartverket surveyed 50 m bathymetry, measured-only fishing spots, Institute of Marine Research fish evidence, seasonal forage guidance and public shore-access context. The outer entrance and island passages west of Ørland. The water tops out around 1976 ft. The depth chart comes from Norwegian Mapping Authority (Kartverket) 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.
The drawn water covers 45,953 acres wrapped in 104 miles of bank, broken up by an island. That shoreline is heavily fingered (development index 3.5) — bays, points and pockets everywhere, which multiplies the fishable edge. Roughly 2% of the water is 15 ft or less, the band where the food chain lives. Tip to tip the water measures near 23.9 mi with a 13.1-mi widest point. If the bite dies, Storvatnet is 4 mi to the east.
The target roster combines named-water evidence where available with conservative, habitat-compatible official Norwegian coastal records. It documents occurrence context, not equal abundance, a catch rate or a promised catch. Closed targets are excluded and current rules control every trip. 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 atlantic cod in skinny water — 20 to 100 ft is the zone. Warm water sends them out to 45 to 180 ft; cold water stacks them in 50 to 220 ft. Rock reef is the standout, a rock pile at roughly 5 ft, rated good for fall atlantic cod. Plan around early morning in the warm months. A heavy metal jig or a large soft-plastic jig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 20 to 100 ft | dawn | Rock reef (5 ft) | Diamond jig, Heavy bucktail |
| Summer | 45 to 180 ft | dawn | Rock reef (5 ft) | Heavy metal jig, Large soft-plastic jig |
| Fall | 25 to 140 ft | dawn | Rock reef (5 ft) | Diamond jig, Bucktail with teaser |
| Winter | 50 to 220 ft | midday | Rock reef (5 ft) | Heavy vertical jig |
Spring saithe (coalfish) on Trondheimsfjord - Outer hold shallow, usually 15 to 160 ft. By summer they slide out to 25 to 260 ft, and by winter most fish are in 45 to 320 ft. The chart's best answer is Shoreline point — point, 63 ft, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a speed jig or a heavy paddletail.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 160 ft | dawn & dusk | Shoreline point (63 ft) | Slim metal jig, Paddletail |
| Summer | 25 to 260 ft | dawn & dusk | Shoreline point (63 ft) | Speed jig, Heavy paddletail |
| Fall | 20 to 220 ft | dawn & dusk | Shoreline point (63 ft) | Metal jig, Baitfish swimbait |
| Winter | 45 to 320 ft | midday | Rock reef (5 ft) | Heavy vertical jig |
Spring puts pollack (lyr) in skinny water — 8 to 100 ft is the zone. Warm water sends them out to 12 to 150 ft; cold water stacks them in 35 to 220 ft. Shoreline point is the standout, a point at roughly 63 ft, rated prime for summer pollack (lyr). Plan around early morning and the evening in the warm months. A surface plug or a baitfish swimbait covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 100 ft | dawn & dusk | Rock reef (5 ft) | Sandeel-pattern lure, Soft-plastic shad |
| Summer | 12 to 150 ft | dawn & dusk | Shoreline point (63 ft) | Surface plug, Baitfish swimbait |
| Fall | 15 to 160 ft | dawn | Shoreline point (63 ft) | Metal jig, Minnow plug |
| Winter | 35 to 220 ft | midday | Rock reef (5 ft) | Slow metal jig, Weighted soft plastic |
Come spring, look for haddock tight to the bank in 35 to 220 ft. Expect a summer slide to 60 to 320 ft, then a winter hold in 70 to 400 ft. Start at Kartverket measured flat. It's a feeding flat holding about 276 ft of water and rates good come fall. Prime time lands in early morning. A compact metal jig or a bottom rig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 35 to 220 ft | dawn | Kartverket measured flat (276 ft) | Small bottom jig, Beaded trace |
| Summer | 60 to 320 ft | dawn | Kartverket measured flat (276 ft) | Compact metal jig, Bottom rig |
| Fall | 45 to 260 ft | midday | Kartverket measured flat (276 ft) | Small vertical jig |
| Winter | 70 to 400 ft | midday | Kartverket measured flat (276 ft) | Deep bottom jig |
Spring puts atlantic mackerel in skinny water — 5 to 45 ft is the zone. As the season builds they drop to 15 to 80 ft, wintering in 30 to 120 ft. Summer atlantic mackerel concentrate at Shoreline point, a good-rated point around 63 ft. Warm-month bites cluster around early morning and the evening. A feather rig or a small vertical jig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 45 ft | dawn & dusk | open water | Mackerel feather rig, Small silver jig |
| Summer | 15 to 80 ft | dawn & dusk | Shoreline point (63 ft) | Feather rig, Small vertical jig |
| Fall | 10 to 65 ft | dawn & dusk | Shoreline point (63 ft) | Compact silver jig, Sparse feather rig |
| Winter | 30 to 120 ft | midday | open water | Small deep jig |
Spring atlantic herring on Trondheimsfjord - Outer hold shallow, usually 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. The chart's best answer is Rock reef — rock pile, 5 ft, good for spring. Prime time lands in early morning and the evening. The summer box starts with a herring feather rig or a small silver jig.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Rock reef (5 ft) | Small herring feather rig, Micro jig rig |

| 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 |

Trondheimsfjord - Outer is about 1976 ft (602 m) deep at its deepest point. The depth chart comes from Norwegian Mapping Authority (Kartverket) bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Official coastal monitoring from Institute of Marine Research four-fjord pelagic survey, 2025 informs the atlantic cod, saithe (coalfish), pollack (lyr), haddock, atlantic mackerel, atlantic herring, sea trout, atlantic halibut, cusk (tusk) roster for Trondheimsfjord - Outer. 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.
Shoreline point is the top-rated area: a point in about 63 ft of water that rates prime for pollack (lyr) in summer. The map above holds the full rated-spot list for every species and season.
For atlantic cod, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
Fishing on Trondheimsfjord - Outer is regulated by the Norwegian Directorate of Fisheries (sea-angling rules). Check the official Norway regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
