Fly Fishing Idrijca

The Marble Trout is the trout family’s biggest and most iconic representative. It can grow up to 130 cm in length, 22 kg in weight, and has a distinct olive-green marble pattern which makes it stand out from other members of its family.

The Grayling is one of Europe’s most popular fly-fishing species, which has seen quite a steep decline in population around the continent. But do not threat, this fish is well-preserved in Slovenia’s waters. Although an increasing number of 50 cm Grayling have been reported in recent years, the minimum size catch measures 45 cm. Characterised by their colourful dorsal fin, Grayling prefer to swim in calmer sections of rivers and fishing with the use of an artificial fly makes it a perfect catch throughout the mid-May to end of October season.

Season: Ordinary Grayling: April 1st – November 30th (Soča river April 1st – November 30th)
Adriatic Grayling: May 16th – November 30th
Slovenian record: 63 cm

As Slovenia’s most widespread Trout species, the Brown Trout can be caught at sizes ranging from 25 (min. size) to 50 cm. It’s mainly found in upper and middle reaches of rivers and streams, Karst waters being home to the largest. This wonderful fish’s colour patterns can vary between dark grey, copper-red, olive green, or yellow-brown, sprinkled with red, white and black spots. The Brown Trout is a beauty that can be found in most popular fishing spots around Slovenia. The fishing season runs from March to November.

Season: March 1st – September 30th

Sharing many of Slovenia’s waters with the Brown Trout is the gorgeous Rainbow Trout. It’s an incredibly adaptable fish and can be found in both manmade and natural habitats – flowing or standing. Thanks to its Rainbow-coloured flank and tiny black dots, this Trout is easily distinguishable from other fish. It can reach a size of 90 cm and weigh up to 10 kg, with the average fishing size between 26 (min. size) and 50 cm. The Rainbow Trout is much braver and more aggressive than its Marble and brown counterparts, which makes its powerful flight tough but very enjoyable. You can catch this creature from the end of March until the end of October.

Season: March 1st – November 30th (Soča river April 1st – November 30th)
