Fish species in lakes

Game fish

Lake trout (Salmo trutta lacustris)

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.

Rainbow trout (Oncorhynchus mykiss)

Rainbow trout are not native to Denmark but are illegal escapees from fish farms - or legal inhabitants of Put & Take waters. Unlike our native trout rainbow trout spawn in spring and generally tolerate higher temperatures and lower oxygen content.

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.

Coarse fish

Pike (Esox lucius)

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 prefer the vegetation zone near the shoreline where they ambush their prey. The heat of summer is usually spent in deeper and colder waters away from the shore.

Perch (Perca fluviatilis)

Perch love the warm water of summer. They like to hang around the vegetation in somewhat deeper water than pike and they often hunt in packs chasing tiny fish up to the surface. Diving gulls will indicate the action from quite a distance. Perch larger than 2 lbs. are considered big.

Pikeperch (Lucioperca lucioperca)

A large and very tasty fish that may weigh 20 lbs. Fish larger than 10 lbs. are rare though. Pikeperch prefer areas of the lake with hard or rocky bottom. Unlike pike they thrive in turbid lakes where they sneak up on their prey using their excellent sense of smell. Also they are active during night.

Pikeperch are caught using natural bait during summer when the water is turbid. In winter trolling wobblers in clear water can be very productive.

Eel (Anguilla anguilla)

In many lakes eels are only legal prey for professional fishermen using traps and longlines. But where legal you may enjoy great fishing for eels using natural bait - worms for the smaller narrowheaded eels and baitfish for the larger broadheaded specimens. Mature eels migrate back towards the Sargasso Sea to spawn during autumn.

Carp (Cyprinius carpio)

The largest of all the cyprinids and thus the most sought after species. It is not native to Denmark but was introduced from South Europe by monks hundreds of years ago. Summer temperatures are normally too low for carp to breed successfully. Still it thrives in smaller eutrophic dams and lakes where it may reach 20 lbs. or more.

Bream (Abramis brama)

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.

Tench (Tinca tinca)

To many people tench are the most beautiful of all freshwater fish. With its ruby red eyes and velvet soft fins it is a very conspicuous fish that thrives in smaller ponds and lakes with clear water and lush vegetation. Fish of 4-6 lbs. are not uncommon and fight hard.

Roach (Rutilus rutilus)

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.
