Sockeye salmon depletion in energy stores. Fat, protein, and somatic energy stores decrease from the final moments in marine migration through freshwater entry, spawning, and death. Sockeye salmon do not feed during reproduction. Feeding ends once they enter into freshwater, which can be several months before spawning. Embryos are maintained with only endogenous food supplies for about 3–8 months. Reproduction in the sockeye salmon has to be accomplished with the energy stores brought to the spawning grounds. How the salmon use their energy during migration and spawning affects how successful they will be reproductively; energy used for migration cannot also be used

Huizi says "You're not a fish [子非魚] — how do you know what fish enjoy?"

(denying that the individuals Huizi and Zhuangzi are identical). Beyond the inherent semantic ambiguities of "Baima fei ma", the first line obscurely asks "ke hu" "Can it be that …?". This dialogue could be an attempted proof that a white
