Gjedde
gjedde.jpgThe northern pike (Esox lucius) are native to the Palearctic and Nearctic ecozones, ranging across northern North America and from Western Europe to Siberia in Eurasia.
In Norway pikes can grow to a maximum recorded weight of 22 kilograms. Individuals have been reported to reach 30 years in age. They have the elongated, torpedo-like form of predatory fishes, with sharply-pointed heads and sharp teeth. Their coloration is typically grey-green with a mottled or spotted appearance. The pike's marking is like a finger print, each with different patterns.
The English common name "pike" is an apparent shortening of "pike-fish", in reference to its pointed head, Old English píc originally referring to a pickaxe.
The pike feeds on a wide range of food sources. Their primary prey is other fish, including their own kind. Their main prey is roach whenever available; they also prey on perch, eels, walleye, whitefish and minnows. They devour fish up to one-third of their own size. Pike are cannibalistic; some 20% of the diet consist of pikes smaller than themselves.
They will also prey on insects and amphibians such as newts or frogs in times when food is scarce, and occasionally on small mammals, like moles or mice when caught water-borne. Small birds such as ducklings may become a target for hungry pike. Pikes are also known to prey on swimming snakes, such as vipers. Big pike have been known to swallow adult wild ducks whole.
The pikes are notoriously voracious carnivores and can be potential pests when introduced into alien ecosystems. Pike angling is becoming an increasingly popular pastime in the UK and Europe. Effective methods for catching this hard fighting fish include dead baits, lure fishing, and jerk baiting. They are prized as game fish for their determined fighting and have been food fish since ancient times. They can easily be damaged when handled. Since they have very sharp teeth and the the teeth are numerous, it is wise to take extreme care when unhooking the pike. The angler also needs to take great care when unhooking a caught pike, as to not harm the gills. It is recommended that barbless trebles are used when angling for this species as it vastly simplifies unhooking. Unhooking should be accomplished using long forceps—30 cm artery clamps are ideal. The pike should be kept out of the water for the minimum amount of time possible, and should be given some time to recover before being weighed and photographed.

I våre områder finnes mange gode gjeddevann. Vi vil særlig trekke fram de store sjøene i Haldenvassdraget, Glomma i Akershus og Nedre Glomma. Av mindre vann med god gjeddebestand kan nevnes Isesjø, Lundebyvassdraget og Elgåvassdraget.


Brown trout
orret.jpgThe Brown Trout (Salmo trutta) is largely a freshwater fish, migrating from lakes into rivers or streams to spawn, although there is some evidence of stocks which spawn on wind-swept shorelines of lakes.
The brown trout is normally considered to be native to Europe and Asia but the natural distribution of the migratory forms may be, in fact, circumpolar. The brown trout prefers cold, well-oxygenated upland waters, especially large streams in mountainous areas. Cover is important to trout, and they are more likely to be found where there are submerged rocks, undercut banks, and overhanging vegetation.
The brown trout is a medium sized fish, growing to 20 kg or more in some localities although in many smaller rivers a mature weight of 1 kg (2 lb) or less is common.
Brown trout are active both by day and by night and are opportunistic feeders. While in fresh water, the diet will frequently include invertebrates from the streambed, small fish, frogs, and insects flying near the water's surface. The high dietary reliance upon insect larvae, pupae, nymphs and adults is what allows trout to be a favoured target for fly fishing.

I våre områder kan ørret fiskes i et stort antall tjern og noen elver. Her vil vi spesielt nevne skogsområdene Fjella og Vestfjella i indre Østfold, samt Kampåa, som er en fin ørretelv nord i Akershus.


Grayling
harr.jpgThe grayling (Thymallus thymallus) is a species of freshwater fish in the salmon family (family Salmonidae) of order Salmoniformes. It is the type species of its genus. Native to the Palearctic ecozone, the grayling is widespread throughout northern Europe.
In Norway the grayling grows seldom to a weight of 1,5 kg. Individuals of the species have been recorded as reaching an age of 14 years.
The grayling prefers cold, running riverine waters. Omnivorous, the fish feeds on vegetable matter as well as crustaceans, insects and spiders, molluscs, zooplankton, and smaller fishes, including Eurasian minnows and yellow perch. Graylings are also prey for larger fish, including the huchen (Hucho hucho).
The term "grayling" is often used to refer generically to the Thymallus species, and T. thymallus is sometimes called the European grayling for clarity. There are many obsolete synonyms for the species.

I våre områder vil vi trekke frem Vorma og deler av Glomma i Akershus som gode harrfiskeområder.
