The effect of feeding frequency and ration level on the
growth and survival of early (5-10 mm CL) juvenile spiny lobster,
Panulirus argus, was determined. Animals were either fed 100% body
weight (BW)/day in the evening, coinciding with the change from light
to dark, or 50% BW/day twice (once in the morning and once in the evening)
daily, also coinciding with light transition. Feeding to excess once
daily resulted in significantly (P > 0.05) greater weight and carapace
length (CL) increases during the 28-day experiment, compared with the
same overall ration divided between two feeding times. Survival rates
between treatments were not significantly (P > 0.05) different during the
trial. The implications for early juvenile spiny lobster culture are that
feeding a high-ration once daily, at the onset of dusk, as compared with
feeding half of the daily ration twice daily, results in improved growth rates.
