Grayling - Norwegian: Harr (Thymallus thymallus)
The Grayling is easy recognized by the big colorful fin on his back. The Grayling is a real freshwater fish and is very common in Norwegian rivers.
The Grayling mates in April and May and lays her eggs on the sandy or with small stones covered bottom of the river. The Grayling is very sensitive to polluted water and needs a large living area to survive. This fish is easy to catch on dry and wet fly and also on nymph. The fish will be active as soon as the ice has disappeared from the river and the water temperature is above c. 7 degrees Celsius. You are able to catch Grayling until ice covers the river.
Trout - Norwegian: Ørret (Salmo trutta)
Trout is a very popular fish among fly fishermen. The Trout in the Glomma and the surrounding lakes is recognized by the orange - brown - black spots on the sides of the fish. The Trout is a real hunter and will even eat its own kind if necessary. Trout up to c. 1.5 - 2 kilos are good to catch on dry flies. Bigger ones are easier to catch on big nymph or on streamers. Big Trout on a fly Rod is one of the sport’s highlights! The best time for Trout fishing is in the early Spring.
Common whitefish - Norwegian: Sik (Coregonus lavaretus)
The Common Whitefish is a common species in the Northern and Eastern parts of Norway. The fish lives in clear, slow-flowing water and in several lakes. The fish mates in the Autumn and Winter and can reach a size up to 60 cms. In big lakes the fish will mate in very deep water at about 50 meters deep. It is possible to catch the fish on dry fly but this technique is probably only for the more experienced fisherman.
Pike - Norwegian: Gjedde (Esox lucius)
Pike is not a species you would normally expect in the fast flowing waters that is found in the Glomma River. However, this fish is common in the easy parts and the ‘dead’ corners of the river. There where the water is very slow-moving and where the bottom is covered with grass. The Pike is a voracious hunter and the biggest threat to all the other species in the river and the lakes. For this reason the local fisherman do not like the Pike at all. Nevertheless this fish is an integral part of life in the Glomma River and can give a fly fisherman some spectacular fishing moments. Each year we see a number of large Pike, up to 12 kilos, caught in the Glomma or the surrounding lakes.
Perch - Norwegian: Abbor (Perca fluviatilis)
The Perch is a real hunter and most common in the lakes in the Koppang area. You will be able to find Perch in the southern parts of the Glomma where the water is not running is fast as in the Northern parts. Several lakes produce Perch up to 1.5 kilos. The Perch is easily recognizable by the distinctive vertical stripes on the body. The Perch mates during the early spring, as soon as the ice is disappeared from the river and the lakes. You can have lots of fun hunting the Perch with a popper or a streamer.
Arctic Char - Norwegian: Røye (Salvelinus alpinus)
Arctic Char is both a freshwater and saltwater fish in the Salmonidae family; it is native to Arctic, sub-arctic and alpine lakes and coastal waters. No other freshwater fish is found as far North as the Arctic Char.
The Arctic Char is closely related to both Salmon and Trout and has many characteristics of both. Individual Char can weigh up to 9 kilos or more. The color of the fish can be greenish-brown to silver gray and they always carry a distinctive red belly. The flesh color of Char varies; it can range from a bright red to a pale pink. After the last ice-period the Arctic Char was the first species to colonize the Norwegian lakes.
Roach - Norwegian: Mort (Rutilus rutilus)
The Roach is a common species in the Norwegian waters and can be found in freshwater lakes and slow flowing rivers. The maximum size of this fish is apprx. 35 cm. Catching Roach over 1 kilo is very rare – but can occasionally happen! The fish is easy recognizable by the red fins and red eyes. Under the right circumstances this fish can reach 25 years in age. The fish mates in the spring when the water reaches a temperature of about 10 – 12 degrees C. You can catch this fish with dry flies and nymphs.
Burbot - Norwegian: Lake (Lota Lota)
The Burbot is the only freshwater fish in the Gadidorm (cod-like) family to spend its whole life in freshwater. The Burbot is only active in cold water and mostly during the nights and so catching one in the summer is extremely rare.
However if you are lucky you might catch one during an ice fishing session in the Winter. They can weight up to 30 kilograms.
