The Salmoninae are a subfamily of the salmon fish (Salmonidae). They are mostly spindle-shaped fish with a slender, slightly flattened body and a large mouth. They are found in the ocean and freshwater in North America, in northern and central Europe, and in northern Asia.

features

Salmoninae have small scales, in contrast to the large-scaled Coregoninae, the second subfamily of salmon fish. They always have more than 110 scales along the sidelines (fewer in the Coregoninae). The short dorsal fin is supported by fewer than 16 fin rays (more in the Thymallinae ). The pelvic fins sit low ( ventral ), the caudal fin is not or only slightly indented. The maxillary is dentate. An orbitosphenoid (skull bone) and a suprapraoperculare (bone of the gill cover) are present.

Way of life

Among the Salmoninae there are migratory fish that live in the sea and migrate to rivers, streams and lakes to spawn, and stationary forms in fresh, stagnant waters. All of them need oxygen and prefer cold waters. They feed on invertebrates and smaller fish.
