Sexual maturity increases mobility and heterogeneity in individual space use in Atlantic salmon (Salmo salar) parr.

abstract：:The recovery of oxygen uptake to the standard metabolic rate (SMR) following exhaustive chasing exercise in Atlantic salmon Salmo salar parr occurred in three phases (rapid, plateau and slow). The initial recovery phase lasted 0·7 h and contributed 16% to the total excess post-exercise oxygen consumption (EPOC). It wa...
