Dear members
The Institute of Freshwater Fisheries in Iceland started in November 1999
research project on behavioural ecology of brown trout (Salmo trutta L.) in
Lake Thingvallavatn (size 83 km2 & max depth 114 m). Spawners were
equipped with data storage tags (DST 200) to sample paired information on
their migration behaviour (depth) and the water temperature experienced.
The aim is firstly to get information on the main distribution pattern of
the trout, in detail vertically and approximately horizontally and secondly
to get information's on some of the relationships and mechanism involved.
The results will serve as landmarks in relation to trout migration in
future assessments in Lake Thingvallavatn in order to conserve the trout
stock(s). More information on the project can be found at:
