“…But also other items have to be considered, because the Hardangervidda National Park regulations also state that it is forbidden to introduce any fish into previously fishless lakes (Anonymous 2003). One of the main arguments for this prohibition is based on the changed densities of many invertebrates like the tadpole shrimp L. arcticus because of fish predation (Aass 1969;Jeppesen et al 2001;Fjellheim et al 2007), and the resulting negative effects such changes may have on other biota (i. e. diving ducks) which feed on aquatic invertebrates (DesGranges & Gagnon 1994). Therefore, the biodiversity of the whole Hardangervidda ecosystem has to be addressed in a combined effort.…”

“…In 2007 B. pomonae was observed in Lake Songa (Saltveit & Brabrand 2008), in Lake Svartavatnet and Lake Svartavasstjørni (Fjellheim et al 2008) on the Hardangervidda Mountain plateau in addition to Lake Sandvatn. A google-search also noted it from the Valdres region.…”

“…The brown trout is an opportunistic feeder and the diet changes with food availability. Examination of stomach contents has proved to be a reliable method to evaluate the animals occurring in a lake and its surroundings, at least in relative terms (Sømme 1934;Aass 1969;Borgstrøm 1970;Fjellheim et al 2007;Qvenild & Rognerud 2018). Especially in the search for L. arcticus this method is sensitive even when L. arcticus occur in low densities (Fjellheim et al 2007).…”

Especially in the search for L. arcticus this method is sensitive even when L. arcticus occur in low densities (Fjellheim et al 2007). Due to its big size L. arcticus is a nutrition rich and highly preferred food item (Aass 1969;Fjellheim et al 2007;Borgstrøm 2016;Qvenild & Rognerud 2018), hence we assume that the frequency of brown trout eating L. arcticus reflects the population densities of L. arcticus.…”
