Kinematics of labriform and subcarangiform swimming in the Antarctic fish Notothenia neglecta
1. The kinematics of labriform and subcarangiform swimming have been investigated for juvenile (7–8 cm) and adult (27–30 cm) stages of the antarctic teleost Notothenia neglecta Nybelin at 1–2 °C 2. Upper threshold speeds using the pectoral fins alone (labriform swimming) were 0.8LS−1 in adult fish a...
