10 <br />Experiment 2, Time to Irreversible Starvation. Time to irreversible <br />starvation, defined as the number of days to cumulative mortality <br />exceeding 50%, was determined from larvae stocked at 10 jar :-l and <br />started on nauplii (300 I 1 concentration) at 4--d intervals beginning <br />d 7 post-hatching and ending on d 31. The experiment was replicated 3 <br />Experiment 3, Effect of Ration Size. Mortality and growth were <br />investigated for 10 larvae jar "l fed nauplii concentrations of 5, 10, <br />50, 100, 500, and 1,000 I 1 feedinrl, with 3 replicates each. To <br />estimate minimm+ prey density necessary for 50% survival, larval <br />mortalities not accounted for (see above) were distributed over dates <br />when mortalities were ]moan to occur according to the following <br />formula (0'Ca7iell & Raymond, 1970) : <br />mn=dn+ (P-S-D) dn/D, <br />where % = total dead on day n; do = dead observed cn day n; P = <br />initial papUlatian; S = survivors; and D = dead cbserved on all days. <br />The data for Experiments 2 and 3 were statistically evaluated <br />using the Mann- itney U-test. Means given in text are followed by <br />+On- standard error. Raw data compilations frma which figures and <br />tables were summarized are available on request from, Papoul.ias, or <br />frcmn Dexter NFH. All data manipulation and analysis was performed on <br />an IE24 PC ccputer using Lotus, Systat®, and Sigmaplot® software.
