| Summary: | Escaped farmed Atlantic salmon interbreed with wild Atlantic salmon, leaving offspring that often have lower success in nature than pure wild salmon. On top of this, presence of farmed salmon descendants can impair production of wild type recruits. We hypothesize that both these effects connect with farmed salmon having acquired higher standard metabolic rates (SMR, the energetic cost of self-maintenance) during domestication. Furthermore, fitness related advantages of phenotypic traits associated with both high SMR and farmed salmon (e.g. social dominance) depend on environmental conditions, such as food availability. We hypothesize that farmed offspring have an advantage at high food availability due to e.g. dominance behavior but suffer increased risks of starvation when food is scarce because this behavior is energy-demanding. To test these hypotheses, we first compare embryo SMR of pure farmed, farmed-wild hybrids and pure wild offspring. Next, we test early life performance (in terms of survival and ... : Growth of Atlantic salmon juvenilesFinal mass of individual Atlantic salmon juveniles at experiment termination given together with the associated mean family egg mass and standard metabolic rate (residuals). Also provided is information on the types of crosses (wild mother x wild father: w, wild mother x farmed father: wf, farmed mother x wild father: fw), food availability treatment (low: L, and high: H), competition treatment (allopatry: w, wf, fw, and sympatry: w-fw, w-wf) and the final number of suriving offspring in each stream channel.Growth.txtOxygen consumption for the Imsa-Aquagen materialO2 consumption in each vial (mg) that contained 5 eggs is given together with mean egg size (g), duration of each measurement period (h), type of cross (wild mother x wild father: ww, farmed mother x farmed father: ff, wild mother x farmed father: wf, farmed mother x wild father: fw) and female and male type (wild: w, farmed:f) and ID.ImsaAqO2.txtOxygen consumption for the Surna-AquaGen materialO2 consumed in each ... |
