Limnology Station

Võrtsjärv Limnology Centre

The Võrtsjärv Limnology Centre, historically known as the Limnology Station, is located on the eastern shore of Lake Võrtsjärv in Vehendi village. The centre is part of the Chair of Hydrobiology and Fisherieslink opens in new page at the Institute of Agricultural and Environmental Sciences of the Estonian University of Life Sciences.

The centre studies the condition, aquatic life, water quality and ecological processes of Estonia’s inland waters, particularly Lake Võrtsjärv, Lake Peipsi and smaller lakes. It participates in national and international research projects and supports the education, practical training and research of future aquatic scientists.

History

After the Institute of Zoology and Botany of the Estonian Academy of Sciences was established in 1947, hydrobiological research became an important part of its work. Studies conducted between 1951 and 1954 showed that water bodies needed to be studied throughout the year, not only during summer expeditions. This created a need for a permanent field station on the shore of Lake Võrtsjärv.

On 14 September 1954, Petseri farm on the eastern shore of Lake Võrtsjärv was taken into use as a field station of the Institute of Zoology and Botany. This date is considered the founding date of the Limnology Station. The farm had no electricity or running water and did not provide suitable conditions for experiments. Plans were therefore made to build a new station.

In 1958, the Estonian Academy of Sciences decided to build a new Limnology Station about one kilometre from Petseri farm. Construction began in 1959. The cornerstone of the main building was laid on 6 May 1961, and the building was officially opened at the end of 1963. Residential buildings, an aquarium pavilion, experimental pools and harbour facilities were also built.

The number of employees and residents associated with the Limnology Station peaked in the mid-1980s, when more than 80 people lived or worked there. At the time, the station was headed by Henn Haberman.

Ingmar Ott became head of the Limnology Station in 1991. During the years following the restoration of Estonia’s independence, state funding, staff numbers and the number of residents connected with the station declined. By the mid-1990s, the centre’s research activities had stabilised.

In 1997, the Institute of Zoology and Botany became part of the Estonian Agricultural University. In 2005, the Võrtsjärv Limnology Station was renamed the Limnology Centre of the Institute of Agricultural and Environmental Sciences at the Estonian University of Life Sciences.

From 2001 to 2017, Ain Järvalt headed the Limnology Station and later the Limnology Centre. From 2017 to 2025, Kalle Olli headed the Chair of Hydrobiology and Fisheries. Since 2025, Alo Laas has served as acting head of the Chair.
