| Lisätietoa: | 1B/2008 About 100 fish species (98 teleosteans, 1 cartilaginous fish and 3 lampreys) were found to be living in Finnish waters. This publication includes a checklist of Finnish fish species which lists the scientific, Finnish, Swedish and English names in a systematic table, and the occurrence of species in fresh and different brackish water areas in Finland is also recorded. Fifty-eight fish species can be considered to be native and resident. Annually, it is possible to find 67 bony fish and two lamprey species in Finnish waters. There are twenty-two marine fish species. More than one third of the species (24) have fresh and brackish water populations and also anadromous ones. The variable conditions (mainly temperature and salinity) have not made it easy for new species to naturalize into Finnish waters. The fish fauna was basically established about 4 000 years ago when the present Baltic Sea era started. Only four species were added to the species list during the last century but two new species were recognised in 2005. Fourteen new fish species have been imported and introduced into Finnish waters. Four of these species have naturalized, i.e. they have established reproductive and self-sustaining stocks after introductions into some water bodies, and four other species are maintained by repeated introductions, though there has been some reproduction success in a few exceptional cases |
