It has been suggested that induced swimming has the potential to improve the growth
performance of fish. We tested this hypothesis by measuring growth, metabolic efficiency
and physiological capacity of common carp (Cyprinus carpio). Fish were swum at different
exercise regimes: 0.0 (control), 1.5 and 2.5 body lengths per second (BL/s) in 1600 L
recirculating raceways for 4 weeks. The results showed a significant increase in weight gain,
specific growth rate, improved feed conversion efficiency, and a higher hepatosomatic index …
