Supposing you suddenly smell the odor of a cucumber bed coming to you on
a warm July midday from cases with freshly caught fish, you could almost
unhesitatingly declare that the cases contain smelt.
smelt feeds on tiny plankton crustaceans and fish young. It plays a significant
part in feeding predator fish species, including salmon, and also sea birds.
Its length does not exceed 13-14 cm. Specimens of 4-10 cm long prevail
in catches. Grows rapidly to become sexually mature in its second year
of life. Enters rivers in late April-early May to spawn. Does not ascend
high in rivers. Spawns on stone-pebble soils in places with rapid
currents. The roe is small and sticky. After spawning, descends to river
estuaries to enter the sea; some fish remain in the river. In summertime,
intensely feeds on various plankton organisms. Commercially is a secondary
species, an object of local and amateur (under-the-ice) fishing in Primorye
