Fish species in rivers
In East-Jutland Atlantic salmon are found
mainly in the River Guden, where they have been introduced recently.
Each year some 5.000 mature salmon migrate back to this river
where anglers are estimated to catch some 1.000 fish yearly.
Salmon caught in other rivers are - with
few exceptions - roamers from the River Guden. Salmon start ascending
the rivers from May-June on until the end of the season. Catches
are dominated by fish in the 4-10 lbs. range - grilse that have
spent but one winter in the ocean.
Sea trout (Salmo
Sea trout are found in almost all the rivers
of East-Jutland. They are fast growing fish that in rare cases
may exceed 30 lbs. The larger rivers have runs of bright fish
in May-June whereas the smaller rivers don't see many fish until
September-October. Usually, the larger sea trout migrate upstream
before the smaller ones.
Like all true trout the sea trout spawn
in November-December. After spawning fish are in bad condition
and such "kelts" should be returned to the water unharmed
even though the law doesn't require it. They are no good for
eating. Much better suited for the table are the smaller, fatter
and immature silvery "greenlanders" that migrate up
the lower parts of rivers during late winter or early spring.
Lake trout (Salmo
Lake trout belong to the same species as
do sea trout and brown trout. They only thrive in a limited number
of lakes offering cold and well oxygenated water. Of these Mossø
and Lake Glenstrup are the most famous. Lake trout may grow larger
than 20 lbs. but rarely exceed 10 lbs.
Lake trout are encountered only while running
lake tributaries to spawn. Very few of these are large enough
to have runs outside the closed season.
Brown trout (Salmo
Red spotted brown trout are common to most
rivers in East-Jutland. They grow slowly and therefore do not
stand much fishing pressure. For this reason more and more fishermen
return their brown trout unharmed to the river. Fish larger than
2 lbs. are rare.
Rainbow trout (Oncorhynchus
Rainbow trout are not native to Denmark
but are illegal escapees from fish farms on the rivers - or legal
inhabitants of Put & Take waters. Unlike our native trout
rainbow trout spawn in spring.
From nature's hand a true fish of West-Jutland.
Still one of the strongest populations of Danish grayling is
found in the upper eastbound River Guden where it was introduced
before World War Two. Grayling seldom grow much bigger than 2
lbs. and spawn in spring - just like rainbow trout. It is the
fly fisherman's dream fish.
Whitefish (Coregonus lavaretus)
Whitefish are salmonids just like grayling
but they prefer slower moving water. They also prosper in lakes
or brackish water bays where they grow larger than in freshwater.
Fish larger than 2 lbs. are considered big.
Pike are the largest freshwater fish in
Denmark and may weigh over 50 lbs. Pike larger than 20 lbs. are
caught regularly but generally fish larger than 10 lbs. are considered
big. Pike like the slow moving parts of larger rivers where they
prefer the vegetation zone near the shoreline.
Perch prefer the same slow moving stretches
of the larger river as do pike. Some perch live all their life
in freshwater while others migrate out into brackish waters like
Bay of Randers. Here they can be encountered during the months
of summer and autumn while they spend the winter back up in the
river. Perch larger than 2 lbs. are considered big.
A large and very tasty fish that may weigh
20 lbs. Fish larger than 10 lbs. are rare though. Pikeperch thrive
in the lower parts of larger rivers like the River Guden where
they like to lie in stretches with a moderate current and a firm
river bed. Often they are caught while fishing for salmon and
One of the most common freshwater fish
of East-Jutland where it can be found almost everywhere - in
canals and slow moving stretches of larger rivers. It feeds mainly
on chironomid larvae that are sucked from the bottom with its
extractable mouth. A popular fish in the lower section of larger
rivers where 4-6 lbs. fish are not unheard of.
The silvery and red finned roach is common
to all of East-Jutland. A popular fish that always seems to be
in a taking mood. Fish larger than 1 lbs. are considered big.
