Research infrastructure

To conduct our environmental analysis and research, we need high-quality experimental resources - research infrastructure. The term covers everything from advanced laboratories and well-equipped vessels to experimental facilities and databases. Contact us if you would like to use any of our facilities!

The Fisheries Research Station in Älvkarleby

The Fisheries Research Station of SLU Aqua produces approximately 140 000 salmon and trout each year to be released in the river Dalälven. SLU's research and breeding of farmed fish is required for an environmentally friendly and animal ethical aquaculture. We welcome the departments at SLU and other researchers to do your research here. We have aquariums, brooks and rivers suitable for experiments.

Ponds, throughs and aquariums

The Department of Aquatic Resources at Drottningholm has great facilities for research such as ponds, tanks and aquariums. Do you want to perform experimental studies on fish or other aquatic organisms together with us? We have the infrastructure that enables research in aquatic environments.

The Biotest basin

The Biotest basin is an approximately 90 hectare embedded water reservoir that is the recipient of heated cooling water from Forsmark's nuclear power plant. This creates a unique environment that is about 8 degrees warmer than the surrounding sea but otherwise natural. The Biotest basin can thus be likened to a time machine for future oceans and is an exciting environment for research on what will happen when the water temperature rises in the future.

Fish Genetics Laboratory (FiskGen)

The fish genetics laboratory (FiskGen) perform genetic analyses of fish and crayfish as part of environmental monitoring and research projects. Most studies carried at FiskGen focus on identifying the genetic population structure of resource species and endangered species. The laboratory is situated at the Institute of Freshwater Research, Drottningholm.

Age laboratories at the Department of Aquatic Resources

SLU Aqua's three age laboratories specialize in age and growth analyzes of fish from Sweden's seas, coasts, lakes and watercourses. Every year, our experts analyze more than 50,000 fish from about 20 different species. The results from our biological analyzes and age determinations are used to assess the status of fish stocks, and constitute important decision bases for both national and international fish management.

Diving Team

Diving is an important part of environmental monitoring. SLU Aqua’s Diving Team includes a competent group of divers who work with environmental analysis, method development, species inventory, various research projects, and maintenance work.

The research vessel Asterix

SLU Aqua's research vessel Asterix is suitable for water sampling, trawling and hydroacoustic surveys. Asterix is rented out with a skipper and can be transported by trailer. Equipment on board includes trawls, winches, research sonar and radar. The vessel is suitable for sampling in both coastal areas and out at sea.

The Electrofishing boat Elritsan

SLU Aqua's electric fishing boat Elritsan is used for environmental monitoring of fish in larger watercourses and in lakes where net fishing and traditional electric fishing are not feasible. With this test fishing method, we broaden our opportunities to research fish and fishing, while we can examine fish in a gentle way. Elritsan is stationed at the Institute of Freshwater Research in Stockholm.

The survey vessel Hålabben

Hålabben is a coastal survey vessel, that can be used for example for trawling or plankton hauls. The vessel is 3 meters wide and can be transported by a lorry which means it can be used in both lakes and the sea with easy transport between them. The home port of Hålabben is Lysekil by the Institute of Marine Research. On board there is a dedicated work area for handling the catch.

The SLU Aqua Sailor drone

SLU Aqua Sailor is an aquatic unmanned ocean vehicle missioned to survey the sea and collect environmental data used in research and monitoring programmes. The autonomous drone has a wide range of benefits compared to traditional ship-based data collection: it has minimal environmental impact, runs quietly, operates in all weathers and offers a smart and gentle data collection.

Database for coastal fish - KUL

The KUL database contains catch data from the coastal fishery. In its current form, KUL has been in operation since 2006. Individual fish data are also stored in KUL. This can be gender distribution or information on the length, weight or age of individual fish. The use of the database consists of two parts, registration and extraction of coastal fishing data. Data are registered through Kreg applications, which supports standardized survey types for coastal sample fishing. Data extraction fr...

Database for electrofishing in streams (SERS)

Welcome to the electrofishing database. Here you can download data from more than 70,000 electrofishing surveys, distributed over approximately 20,000 sites. You can also find information about how to conduct environmental monitoring using electrofishing as a method. The database for electrofishing in streams (SERS) is the Swedish national database for electrofishing data and has been in use since 1989. All data is publicly available.

Database for Survey test-fishing - NORS

The Department of Aquatic Resources collects, quality assures and stores test-fishing data generated in national and regional environmental programs. The database for survey test-fishing (NORS) contains data from test fishing in thousands of lakes. The database is in Swedish.

Database for Marine fish - FD2

The database FD2 host quality assured data on marine fish and shellfish collected in monitoring surveys and other marine investigations at the Department of Aquatic Resources. The database is the national platform for data collection within the EU data collection framework (DCF) and data is reported to the intergovernmental marine science organization The international Council for the Exploration of the Sea (ICES), for further analysis and advice for the Common Fishery Policy (CFP).

Swedish Crayfish Database

The Institute of Freshwater Research is in charge of the Swedish Crayfish Database, which consists of noble crayfish and signal crayfish occurrences, crayfish test fishing events and crayfish plague occurrences.

Biological archive

The biological archive at SLU Aqua´s Institute of Freshwater Research are constantly being replenished. Each year we collect tissue samples from fish, samples that are used to analyze age and growth, but we also use them in kinship analyzes and chemical analyzes. The tissues can help answer questions about fish stocks in lakes and streams and how they change over time.

The Library at the Institute of Freshwater Research

The library at SLU Aqua´s Institute of Freshwater Research has books and other media in the disciplines ecology, fisheries biology, fisheries management, genetics, limnology, environmental and natural sciences. There are over 2 500 book titles in the library.

Fish measuring boards and envelopes for scales and otholits

You can purchase both measuring boards and sample bags, that we use when sampling fish, directly from us. The measuring boards are made of plastic with millimeter lines. The sample bags are designed for biological samples such as otoliths and fish scales, and are made of special archival paper with pre-printed data. Contact us to make your order!
