Long-term Changes in the Ichthyofauna of Latvia’s Inland Waters

2011
Eriks Aleksejevs, Janis Birzaks

Changes in the ichthyofauna of Latvia’s inland waters and their causes have been analyzed. Information about the distribution and occurrence of fish, obtained from various sources of literature, official reports, "BIOR" data bases on fishery statistics, as well as field research done from 1990 to 2010, has been collected and compared. Anthropogenic activity in the 20th century, such as rivers blocking by dams and fish introduction and acclimatization, has affected ichthyofauna more significantly.
