Description
Background
We studied postrelease explorative behavior and stress tolerance of Landlocked and anadromous Atlantic salmon and their hybrids. For the research, we hybridized the Landlocked salmon of Lake Saimaa with a Baltic anadromous salmon from River Kymijoki, Southern Finland (strain originally from River Neva, Russia). These fish were hybridized in November 2017 and October 2018 in the Kainuu Fisheries Research Station, Paltamo, Kainuu, Finland (kfrs.fi).
In the data the fish are treated as four strains (column 'Strain'): 1. Purebred Landlocked salmon (LLxLL), 2. hybrids, where the maternal population was landlocked salmon (LLxBA), 3. hybrids, where the maternal population was Baltic anadromous salmon (BAxLL) and 4. purebred Baltic anadromous salmon (BAxBA).
Experiment 1. Post-release exploration
In experiment 1., consisting of two separate trials, we studied post-release exploration of the fish in four circular seminatural streams. (Datasets 'Exploration2018.csv' & 'Exploration2020.csv', see also 'Figure_1.jpg')
Experiment 2. Stress tolerance
In experiment 2. we studied the stress response and recovery of the fish (Dataset 'Stress_BernoulliData.csv', see also 'Figure_2.jpg').
Notes
All data is given as .csv-tables (comma separeted values), where ';' serves as separator.
