N2  - Individual Stage I, III and V phyllosomas of the rock lobster Jasus edwardsii were fed daily with a fixed number (2, 4, 8, 12 or 16) of brine shrimps (Artemia salina, 2&#8211;3 mm long) under four different continuous light intensities (10, 0.1, 0.001 and &#x2264;0.0002 &#181;mol s-1 m-2) to determine the optimum requirement for growth and survival. Phyllosomas of each stage fed higher rations of brine shrimps had a significantly shorter intermoult period and larger post-moult size. Light intensity had a significant effect on the post-moult size of Stage I phyllosomas but had no effect on the intermoult period. Individual Stage I, III and V phyllosomas were also fed daily with fixed numbers (2, 4 and 8 respectively) of brine shrimps in containers with different volumes (10, 20, 40, 60, 80, 120 and 240 mL) to alter the prey density while maintaining prey numbers. Prey density had no significant effect on intermoult period or post-moult size but did affect consumption rates. The results are discussed in relation to large-scale culture of phyllosoma larvae.
