Ontogeny of critical swimming speed of wild-caught and laboratory-reared red drum Sciaenops ocellatus larvae
Critical swimming speed (Ucrit) provides a useful estimate of maximum swimming performance for fish larvae that can be used to assess transport and migratory potential. We measured Ucrit of red drum Sciaenops ocellatus larvae through its ontogeny and compared the swimming performance of laboratory-r...

Critical swimming speed (Ucrit) provides a useful estimate of maximum swimming performance for fish larvae that can be used to assess transport and migratory potential. We measured Ucrit of red drum Sciaenops ocellatus larvae through its ontogeny and compared the swimming performance of laboratory-reared larvae to that of wild-caught individuals. Ucrit increased with ontogeny (size), even though variability in Ucrit at any ontogenetic state was large. Ucrit for wild-caught larvae increased from 9.7 to 22.2 cm s–1 over the range of 8.3 to 16.3 mm TL and from 1.1 to 20.5 cm s–1 over the range of 3.0 to 19.1 mm TL for reared larvae. The ontogenetic increase in critical swimming speed occurred in 2 phases—an early phase of rapid improvement and a later phase of slower improvement. This sharp change in the trajectory of swimming performance coincided with important changes in ecology, morphology, and hydrodynamics. During the early phase, larvae were pelagic, their growth was highly allometric, especially in the caudal region, and they swam in the inertial hydrodynamic regime. The onset of the later phase coincided with settlement into seagrass beds, isometric growth, and inertial effects on locomotion.
