Keywords:

  • predation, compensation and context dependence;
  • Atlantic salmon, vulnerable to predators - at every stage of their incredible life cycle;
  • Atlantic salmon, running a lifelong gauntlet of predation risk;
  • life cycle of Atlantic salmon - complex and variable;
  • salmon fry, vulnerable to piscivorous fish - from gravel nests to seek territory;
