Age laboratories at the Department of Aquatic Resources

At the Institute of Marine Research, age analyzes are mainly performed for stock assessments within the EU Data Collection Directive (EU-MAP / DCF).

Among the species analyzed are herring, sprat, cod, saithe, European plaice and Witch flounder.

The majority of the fish that we study are collected in internationally coordinated fish surveys with research vessels and from commercial fishing vessels.

At the Institute of Coastal Research, we perform age analyses in three main areas:

1. Regional and national coastal environmental monitoring.
2. Environmental monitoring at nuclear power plants.
3. The EU Data Collection Directive (EU-MAP/DCF).

Among the species we analyse are perch, herring, eel, vendace, viviparous eelpout, whitefish, European flounder, pike-perch and the round goby.

The fish we age analyse are collected during standardised fish surveys, which we carry out within the various programmes for regional and national environmental monitoring and within the monitoring programmes at the nuclear power plants. A certain proportion of the fish also comes from internationally coordinated fish surveys with research vessels and from commercial fishing.

At the Institute of Freshwater Research, we primarily perform age analyses on fish in three main areas:

1. National environmental monitoring of small and medium-sized lakes.
   
   
2. Monitoring of fish stocks in Sweden's largest lakes: Lake Vänern, Lake Vättern, Lake Mälaren and Lake Hjälmaren.
   
   
3. The EU's data collection directive (EU-MAP/DCF).

Some of the species we analyze are perch, roach, pike-perch, smelt, salmon and eel.

The fish that we analyze mainly come from standardized sampling in lakes, hydroacoustic surveys and via collections in collaboration with professional fishermen.
