features
Salmo dentex usually reaches a length of 20 to 25 centimeters, in the Hutovo Blato wetland animals with a length of almost 60 centimeters and a weight of over two kilograms have been found. The body is elongated and laterally flattened. The head is pointed with a narrow snout. The back is silvery, towards the belly the color fades to the white belly. Small black spots on the head and body are mainly in the upper area, while dark red spots with a light border of various sizes are distributed over the entire flank. The lateral line organ runs through 115 to 122 scales. The fins are gray and turn orange during mating season. The dorsal fin has four hard and nine to ten soft rays, the anal fin has four hard and seven or eight soft rays. The pectoral fins have two hard rays and eight soft rays, the ventral fins have one hard ray 11 to 13 soft rays. The caudal fin has 19 rays, the adipose fin one. The gill trap has 11 to 13 thorns on the right and 12 to 14 thorns on the left.
Way of life
Salmo dentex colonizes large rivers and lakes, with two different morphs occurring (“brown trout” and “lake trout”). Some populations overwinter in deep lakes and move into the rivers in summer. The spawning season is likely between November and January. The eggs are laid on gravelly ground.
