The SALMUS project (funded by CBC Kolarctic) aims to harmonize research and monitoring methods for the endangered freshwater pearl mussel and their host species (salmonid fishes like Atlantic salmon and brown trout) in the Fennoscandian Green Belt region and includes international project partners from Finland, Russia, Sweden, and Norway. NIBIO Svanhovd contributes to these monitoring efforts in northern Norway and Finland.

Freshwater pearl mussels (Margaritifera margaritifera) are a key species in freshwater ecosystems because they provide ecosystem services like, for example, water filtration and nutrients that benefit other species like fish (check also out our fish projects here!). Their life cycle is closely linked to host species (i.e., Atlantic salmon and brown trout) for the mussels’ larvae. Hence, conservation of this endangered species is critically dependent on management strategies that include species interactions and knowledge production to increase our understanding of freshwater ecosystem functions.

The SALMUS project aims to harmonize research and monitoring methods in the Fennoscandian Green Belt region and includes international project partners from Finland, Russia, Sweden, and Norway. NIBIO Svanhovd contributes to these monitoring efforts in northern Norway and Finland.

However, the main goal of NIBIO Svanhovd researchers is to better understand the ecological and social benefits of freshwater pearl mussels, Atlantic salmon, and brown trout in their river ecosystem. To improve our understanding of what people use and value most, we have developed a survey, which is open for participation:

Abstract

Grense Jakobselv ble undersøkt fra Lasarudskulpen og oppstrøms til grensemerke 312 høsten 2020 for forekomster av elvemusling. Det ble registrert 470 elvemusling like ovenfor Larauskulpen på et begrenset område. Ingen elvemuslinger ble funnet videre oppover elva. Tellingen er ikke utfyldende for bestanden på norsk side, til det er det nødvendig at grensen åpnes i området. Gjennom vannet ble det også observert mange muslinger på russisk territorium. Det ble også påvist små muslinger som ble påvist, imidlertid utgjør andelen fra 50 mm og mindre omtrent 10 % av bestanden, så reproduksjonen er svak. Det ble observert svært få vertsfisk under undersøkelsen.
