Mean counts and 95% confidence intervals of BrdU-labeled cells normalized to the average value for dusk within each diet treatment, for the different sampling times over a 24-hour period. There was a significant diet versus time interaction for cell count data, and thus the normalized ranked data were analyzed separately for each diet. Statistical similarity within the UN treatment is denoted by the same letters; there were no significant differences between time periods for the SP data. When lobsters are fed unenriched Artemia, cell proliferation is significantly greater at dusk than at any other time of the day. Cell proliferation between 09:30 and 12:30 averages 50% that of the dusk period, and all 95% confidence intervals are < 60%. When lobsters are fed the Spirulina enriched Artemia diet, cell proliferation during the day is relatively uniform, with only the dawn (05:30–08:30) and pre-dusk (13:30–16:30) time periods averaging 80% that of the dusk period.
