Assisted gene flow has been experimented to improve low genetic diversity of critically endangered Saimaa landlocked salmon (Salmo salar m. sebago) by crossing it with genetically more diverse Baltic salmon. The aim of this study was to find out how hybridisation and parasite infection affect the activity, growth, and predation susceptibility of Saimaa landlocked salmon. The experiment was conducted in semi-natural conditions by using Saimaa landlocked salmon, Nevajoki Baltic salmon, and hybrids of these two populations, Diplostomum pseudospathaceum eye fluke as parasite and northern pike (Esox lucius) as predator. Hybridisation increased growth of landlocked salmon, whereas presence of predator and parasite infection reduced activity and growth. Infection increased susceptibility to predation of all salmon crosses. However, hybridisation had no significant effect on susceptibility to predation. These results indicate that hybridisation improved the fitness-related traits of landlocked salmon, such as growth, which suggests improved foraging abilities. Increased growth may influence also other fitness-related factors of Saimaa landlocked salmon, which warrants further research.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2022-03-02T05:42:59Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2022-03-02T05:42:59Z (GMT).
