Alien Species of Aquatic Invertebrates and Fish in the Belarusian Part of the Neman River Basin
摘要
Abstract
The article summarizes and analyzes the published data and results of our own research on nonindigenous species (NIS) of aquatic invertebrates and fish and pathways of their penetration and further distribution in the Belarusian part of the Neman River basin. There are 18 established NIS of aquatic invertebrates and fish up to date: 8 NIS of macroinvertebrates and 10 NIS of fish. It was shown that the main way for invasion of aquatic invertebrates was canals. The main way for invasion of fish was intentional introduction for the purpose of fishing. The list of potential nonindigenous species of aquatic invertebrates and fish that can be introduced in the near future is given.
