Research infrastructure for wild fish stocks

We carry out a wide range of research projects on wild fish stocks in lakes, rivers and marine areas, using a variety of research methods and tools to assess the status of fish stocks. Fish preprocessing and measurement facilities in the research infrastructures of Utsjoki, Inari, Kolari, Paltamo, Oulu, Vaasa, Lammi, Parainen and Helsinki enable a wide range of research on wild fish stocks.

• Research platforms: fish preprocessing and measurement facilities in Inari, Kolari, Taivalkoski, Paltamo, Vaasa, Lammi, Parainen and Helsinki.
• Monitoring of fish stocks using various methods, including experimental fishing (gillnetting and electrofishing), eel surveys (including ARIS echosounding, trapping and tagging), processing of fish samples (biological samples and bones) and ageing of fish.
• Equipment: ARIS echosounders, electrofishing equipment, underwater video cameras, space and equipment for biological sampling and ageing of fish.

• Research platforms: fish preprocessing and measurement facilities in Oulu, Vaasa, Parainen and Viikki.
• Fish stock monitoring: monitoring and research on the state of fish stocks in the Gulf of Bothnia, Archipelago Sea and Gulf of Finland.
• Long-term monitoring and research projects: research service for marine wild fish stocks using a variety of methods, including exploratory fishing, catch sampling, sample processing and tagging methods.

• Research platforms: the Inari fish preprocessing and measurement facilities.
• Monitoring and research projects on fish stocks and fisheries in the Lake Inari basin and the Loka and Porttipahta reservoirs.
• Research methods: research and monitoring of wild fish stocks using a variety of methods, including sampling of catches by professional fishermen, exploratory fishing (purse seine, trawl, net, electrofishing), echosounding, processing and sampling of sample fish, preparation and ageing of broodstock.

• Research platforms: Kolari, Oulu and Paltamo.
• Monitoring and research on the status of salmon, sea trout and whitefish stocks in the Tornio river basin.
• Methods: monitoring the status of fish stocks in the Tornionjoki river basin using various methods, including ARIS echosounding, underwater video monitoring, telemetry, electrofishing and processing of fish samples (biological samples and broodstock).

• Research platforms: Utsjoki and Inari.
• Monitoring the status of fish stocks using various methods, including ARIS echosounding, underwater video monitoring, telemetry, electrofishing, surface diving, processing of fish samples (biological samples and bones) and age determination of salmonids.
• Equipment: ARIS echosounders, electrofishing equipment, underwater video cameras, space and equipment for biological sampling and ageing of fish.
