To determine the effect of fish age on the swimming speed of larvae from hatching through the onset of settlement, we evaluated the swimming speed (Ucrit) of A. percula larvae at 0, 4, and 8 dph (day post hatch), and of E. lori and E. colini at 0, 10, 20, and 30 dph . At the start of each trial, an individual larva was acclimated to the flume for 2 min with water flowing at a velocity of < 1 cm s-1. If the larva displayed normal orientation and swimming behavior during acclimation, then the velocity was increased 2 cm s-1 every 2 minutes until the larva could no longer maintain position and was either expelled from the flume or collected on the back mesh. Following trials, recollected larvae or siblings from the same clutch were photographed using a dissection microscope, and photos were measured for standard length using ImageJ (NIH, USA; Table 2). A larva\u2019s maximum swimming speed (Ucrit) was then calculated following the equation from Brett (1964).
Recorded critical swimming speed of larval Amphiprion percula, Elacatinus lori, and Elacatinus colini measured throughout development from hatching through settlement. Studies performed at Boston University, USA and the International Zoological Expeditions Field Station on South Water Caye, Belize (16o 48\u2019 92\u201d N, 88o 04\u2019 89\u201d W).
