New fly-fishing season is here! Some Slovenian fishing associations have opened their rivers to fish salmonids on 1.march. Me and my friend Martin took advantage of this situation and went to river Rizana. This small river always prepare a surprise and no difference was this time.

Due heavy raining during the night, the water level raised 30 centimeters and so the water conditions were almost prohibited. The only good places to fish were under small dams and right after river curves, where the water swirled and slowed down it´s speed. We used heavy nymphs and streamers in bright colours. Despite bad conditions (we also had some rain periods) we realised some brown trout catches.

Despite all it was a good start of the season. Hope it will last till the end…

Here we are in june and the fishing season is opened for almost all of the salmonids (except the Danube salmon). The last one to open was the grayling (Thymallus thymallus). Some rivers are more abundant with grayling, and one of those is certainly Soca (Isonzo). Despite many other rivers who have less water the Soca river is still now higher and more turbid than normal. The main reason is the snow that is melting on the Julian Alps.

I decided to visit it to see if the fishes became active in this period. I started fishing upper the village Kobarid (Caporetto) near the confluence of river Boka and Soca. Here the water was very clear and you could see it´s inhabitants very far away. I tried under some rapids and caught some graylings with heavy nymphs. I also tried some streamers and dry-flies, but without success.

In the afternoon I moved to the “No kill” part, which was very crowded with fishermen. Here the water was turbid and higher and so was the fish activity. They were lying on the bottom and disinterested for the flies. I saw only 1 fish rising, and caught it with a dry-fly.

In my opinion I would recommend to visit the upper part of Soca river, because in lower part the fishes are not so active on the surface and in the mid-level. For those who prefer fishing with streamers the lower part would also be an option.

The angling club Rence which i am part of also manages a part of Vipava river, where only catch and release  is allowed. It´s about 1 kilometer long area inhabited by salmonids.

Our goal is to make no intrusion to aquatic habitat and let the nature do it´s work. I think this should be the practice on all running waters, but for now it´s only a dream.

After 1 year of break we decided to visit this part to see the conditions after two huge floods that striked last year.

My first impression is, that a lot of changes occurred, with a lot of new gravel accumulated on the bottom of the river. Because of less rain and snow the water is clear and low, so you can see the bottom several meters below the surface. The fishing approach must be subordinate to these conditions.

What impressed me most is the quantity of grayling  (after those floods i was skeptic about the quantity and quality of fishes living in the Vipava river). I estimate that the average size is about 25-30 centimeters and all the time we were fishing, they were very active on the surface. We tried to avoid them as much as possible, but for some of them we were not enough  watchful.

On the nymph we catched some smaller marble trout, which indicates that less intrusion of men is more productive in terms of quality and quantity of the water ecosystem.

This river flows in Vipava valley, which is situated in western part of Slovenia. It´s a karstic river and it´s 44 kilometers long. It could be divided in two parts: the upper part is faster and shallower and appropriate for salmonids. The lower part is deeper and slower and is ideal for cyprinids. Now is turn to write something about the upper part.

The most celebrate salmonid which lives in this river is the indigenous marble trout. Other species that lives in this part are: brown trout, grayling, rainbow trout and hybrids (marble X brown). Despite the river size you can find marbles up to 15 kilograms (found one dead last year), browns up to  5 and graylings bigger than 50 centimeters. The rainbow trout was introduced in the last seventies and now represent a threat for habitat and food. In this part you can find also some cyprinids such as chub, common nase, common barbel and some smaller species.

Because of the majority salmonid population the principal fishing technique is fly fishing, but also spinning (in some areas) is allowed. The best time for fishing is in may and june when a large number of insects swarms (especially big caddisflies) and in september and october when fishes became more voracious because of the winter approaching. Especially graylings became very active on the surface and you can catch them easier than in other months.

For now is all. Down i put some pictures to make an idea of the river and its residents.


This marble trout was found dead last summer (15,60 kilograms).
