11 <br />Results <br />EKperiment 1. Fifty-four percent of unfed larvae were dead by d 25 <br />post hatching. By 50 d, all larvae had died. The majority died <br />between 20 and 30 d after hatching (Fig. 1A). Dead fish averaged <br />9.6±0.2 mm TL (W28). <br />Experiment 2. No mortality was experienced by larvae receiving food <br />frcaa d 7 post hatching. Larvae that received food beginning on d 11, <br />15, and 19 had respective mortalities of 10.0, 10.0, and 26.7%. There <br />were no significant differences (.l>p>.05) among days 7, 11, 15, and <br />19 (Table 1). Highest mortalities occurred when larvae were without <br />food for 27 (86.7%) and 31 d (93.3%). There were no differences <br />between these levels at .1>p>.05. The majority died between 20 and 30 <br />d after hatching (Fig. 1B-H) at an average size of 9.3±0.1 mm TL <br />(W35). Surviving larvae were largest (1-24; 23.0±0.5 mm TL) when fed <br />from 7 d after hatching and smallest (W2; 15.1,16.4 mm TL) when fed <br />beginning 31 d after hatching (Table 2). <br />Rn)eriment 3. Mortality was greatest, but not significantly different <br />(.l>p>.05), when larvae were fed concentrations of 5 or 10 nauplii <br />L'l. Larvae fed 50, 100, 500, and 1,000 nauplii L 1 all had 520% <br />mortality, with no significant differences (.1>p>.05) among treatments <br />(Table 3). Mortalities leveled when larval deaths resulted in food <br />c rcentrations available to survivors of at least 10 to 20 nauplii <br />fish7-1 in 5 and 10 nauplii L 1 treatments (Table 4).
