The river

Otra, with a total length of about 245km, is Norway’s 8th longest river. The River follows Southern Norway’s main road North Rv 9 where it eventually flows out into the sea in the heart of Southern Norway’s capital, Kristiansand.

Along its course, Otra has a lot to offer, and it often changes from torrent white water to wider slower flowing areas, to small and large lakes.

Otra is an exciting river, with the lower 16km housing migratory Atlantic salmon, sea trout, as well as wild brown trout and European freshwater eel. In 2014, 6537 kg of fish were caught in the lower parts. 94% was wild Atlantic Salmon.

As we move upstream from where the migratory fish meet their artificial stop in Vennesla, the Otra takes form as multiple joined lakes and small rivers. Large quantities of wild brown trout, with a small average size, live here but in such a number, one is almost guaranteed a catch!

Otra Fishing Association (Otra Fiskelag)

In June 2023, Otra Fishing Assoiation will launch a “smart Fishing license”, together with Fishby, to develop a sustainable future for angling tourism in the valley. With a Fishby fishing licese, you get access to the whole upper 180 kilometers of the Otra river system in Setesdallen Valley. From Hartevatn at Hovden in the north to Kilefjorden in the south. Note that the Fishby license does not include fishing after migratory species.

The most common trout here is the wild brown trout, but some wild American brook trout can be caught too. Common are average-sized fish of around 300g (3/4lb) but hidden amongst them are some leviathans reaching 8kg (17.5lbs). There is a unique salmon species living in Byglandsfjorden, called Bleka. The fish is often no larger than 250 grams, but its distinctiveness makes it a sought-after fish.

South of Fennefossen, in Evje, you can find perch, whereas, in the higher reaches of the river, you will find minnows.

Two treasures: marble trout and Bleka

The upper Otra river system hosts two internationally unique species that can only be found here:

Southern Norways’ Marble trout

Its distinctive lines resembles the Salmo Marmorata, which is Native to Northern Italy and Slovenia, and some parts of Croatia. However, studies have shown that the fish is a hybrid between a common Broun Trout (Salmo Trutta), and American Brook Trout (Salvelinus fontinalis). Specimens up to 500g have been caught in Evje municipality.

Bleka

Byglandsbleka (also called “bleka”, from the Norwegian word for “pale”), is a dwarf salmon (Salmo Salar), that spends its entire life landlocked in the upper parts of the Otra River system.

Bleka, often mistaken for brown trout, is a dwarf salmon

When ocean levels rose after the last ice age, Atlantic salmon entered the lake, but as the climate changed, the Byglandsfjord became cut off from the sea. Now the adult bleka lives in the lake, which is at 33km2 and has a maximum depth of 167m.

The bleke formed a regular part of the diet for locals until two environmental threats nearly wiped the whole population out. First, a hydroelectric dam, built in 1905, made many of the spawning grounds inaccessible; then, from the 1950s onwards, acid rain from the industries of northern Europe wreaked further havoc. By the early 1970s, it was estimated that only around 200 breeding adults were left.

Today, 50 years after the population collapse, the continuous and ongoing rescue efforts have taken us a long way towards the goal to restore a self-reproducing and harvestable bleke population. If this goal is achieved, the bleke may regain its previous position as an important part of local culinary culture, with positive implications for recreation, tourism, and business development.

How the Boutique works

You always buy from one fly tyer at a time

When you add a fly or set to your cart, you buy from the fly tyer who tied it. Add as many flies as you like from this fly tyer.

You can not add flies from multiple tyers, because else you would have to pay shipping cost for each one, making your shipping cost very high.

Estimated delivery time is shown in the shopping cart

Some sets and flies can be in stock, others might be tied to order. The item that takes the longest will determine the total time your order will take.

The estimated time your order will take is always shown in the shopping cart before you check out.

Thanks for supporting an independent fly tyer!

Catching your next fish on a fly tied by an individual fly tyer is a unique experience. You can be sure that the flies you buy are tied with care and attention to detail.
