AbstractThe effects of starvation upon survival, growth and molting interval of newly hatched spiny lobster (Panulirus japonicus) larvae were examined. Newly hatched phyllosoma larvae were divided into five groups, which were starved for 2, 10, 24, 48 and 72 hours. The effects of starvation after hatching appeared to be restricted to lengthening of the first molting interval. First molting was delayed by a time proportional to the starvation period. This result indicates optional preparation of food organisms before phyllosoma larvae hatch out.

Mouthpart and foregut structure indicates that Jasus edwardsii phyllosomas ingest soft fleshy foods such as gelatinous zooplankton. Mouthpart morphology changes little during larval development, indicating that ingestive capabilities and external mastication are well developed from an early age. However, the density and complexity of setation and robustness of individual mouthparts increases with age, suggesting a greater capacity to ingest larger prey during development. The foregut consists of a single chamber with a number of well-developed grooves, ridges, and setae but lacking a gastric mill. The primary role of the foregut is mixing, sorting, and filtering particles, preground by the mouthparts. Phyllosomas have been divided into early (stage I–III), mid (IV–V), and late (VI–X) stages based on the development of the filter press and main brushes. Increasing robustness of setation and complexity of the foregut suggest that the texture of prey becomes more muscular (fibrous) with larval development. The results presented here suggest that early-stage phyllosoma would benefit from a diet comprising soft gelatinous items, whereas late-stage phyllosomas are better prepared to deal with larger, fleshy prey. The changes in structural characteristics with age should also serve as a guide in the development of formulated diets.
