Abstract:

The two morphotypes (leiurus and trachurus) of the three-spined stickleback Gasterosteus aculeatus, caught at the same location and time in the River Scheldt (Belgium), were investigated for physiological differences in swimming capacity and energetics associated with migration. Critical and optimal swimming speeds, maximum speed and gait-transition speed were significantly higher for the trachurus type. Standard metabolic rate and active metabolic rate were also higher for trachurus, as was scope for activity. Energy stores (protein, lipid and glycogen in liver and white muscle) were mostly similar in the two types, but lipids in trachurus liver tissue were significantly higher.

Keywords: critical swimming speed; energy stores; escape performance; maximal swimming speed; optimal swimming speed; oxygen consumption
