The body of the koryushka fish (European smelt) is typically 15 to 18 cm long, slender and slightly flattened on either side. Larger fish may reach 30 cm in length. Smelts have a slightly translucent body. The back and sides are grey-green to pink in colour, the flanks bright silver. The tailfin has a dark border. The smelt lives for up to six years. One characteristic is its intense smell, reminiscent of fresh cucumbers. (source Wikipedia)
