The roach fish that looks like whitefish is asp: unlike whitefish it does not have the small adipose fin between the tail and the dorsal fin. Also, the asp has a large mouth; it reaches a long way under the eyes. Asp may grow to a length of one meter and weigh almost 10 kilograms (that is approximately twenty-two pounds). In the nineteen eighties (1980’s) asp was endangered in Finland – it had died out completely from the Kymi river. Thanks to the culturing work by Finnish Game and Fisheries Research Institute it has been restored. Today, the asp reproduces naturally in several waterways.
