New fish species in the Russian part of the Gulf of Finland and inland water bodies of St. Petersburg and Leningrad Oblast.

Abstract

Results of recent observations of alien fish species (anchovy, piranha, Chinese sleeper, rainbow trout, peled) in water bodies around St. Petersburg (Gulf of Finland, Lake Ladoga, and surrounding rivers and lakes) are presented. Relatively new species, i.e., the species that have increased their distribution area recently (sabrefish, zope, sprat) are discussed as well. The causes of such events are discussed. The fishing and overfishing of local fishes are considered as the most significant ones.
