Table 1.

Parameter estimates from three statistical models that best describe survival of Atlantic salmon juveniles with wild parents (n = 108, no. stream channels = 18), farmed mother and wild father (n = 78, no. of stream channels = 13) and wild mother and farmed father (n = 78, no. of stream channels = 13) in allopatry and sympatry and at high and low food availability in semi‐natural channels. For juveniles with two wild parents, the estimated slopes for survival effects of family‐level embryo SMR at high and low food availability treatments and for family‐level embryo mass (mean centered) are also given. All values are on logit scale and given as treatment contrasts
