Thymallus thymallus

Grayling is an endemic salmonid species to our rivers. It lives is all our rivers except Kneža, Koritnica and Bela. In our waters it grows to 60 cm (23,5') and 2 kg (4,5 lb) in weight. It is well known from its long lively colored dorsal fin. It feeds almost exclusively on aquatic insects because of its soft mouth but the larger specimens go for other smaller fish as well.

Because of its notoriously cautious feeding habits and its special looks this fish is vary prized by fly fisherman.

Season: May 15th - October 31st
Min. size: 45 cm

Marble trout

Salmo trutta marmoratus

The Marble trout is an endemic species of the Adriatic watershed. It grows considerably larger than other species of fish in our waters. The biggest specimens documented were over 120 cm (47') long and weighed over 20 kg (44 lb). It is discernible from other trout by its unique marble pattern and a disproportionally large head which takes a quarter of its full body length. It feeds on aquatic insects, but mainly on other fish.

Because of its size and elusive nature the "Marble" is very sought after and is considered a true achievement of every fly fisherman.

Season: April 1st - September 30th
Min. size: 60 cm


Leuciscus cephalus cabeda

Chub is an endemic species from Cyprinidae family typical for Adriatic region. Usually this fish lives in shoals. Its body is cylinder shaped and it has quite large scales all overs its body. It can grow up to 70 cm (25,5') and to 5 kg (11 lb) in weight. It feeds on aquatic organisms, plants and fruit.

Because it is considered a white fish it has been frowned upon by fisherman, but this fish can be a real fighter and can be very difficult to catch on a fly.

Rainbow trout

Oncorhynchus mykiss

Rainbow trout is an allochthonous species in European rivers. It established itself because of easy farming and adaptability to different man made and wild habitats. It does not crossbreed with marble trout but it competes with it for food and space. It is easily discernible from other fish from its rainbow colored flank and small black dots on its whole body. It can grow to 80 cm (31,5') an up to 8 kg (17,5 lb) in weight. It is not a very picky feeder eating both aquatic insects and other fish.

Because of its aggressive nature and a strong fight, it is quite an interesting fish for fisherman.
