Observations on the feeding and moulting of laboratory reared phyllosoma larvae of the spiny lobster Panulirus homarus (Linnaeus) under different light regimes

摘要

Phyllosoma larvae of the spiny lobster Panulirus homarus hatched under laboratory conditionsudwere fed on 1-2 day old Artemia salina nauplii. The feeding intensity and moulting frequency of the larvae were studied. When fed with one day old Artemia nauplii, the phyllosoma larvae consumed at an average rate of IS.l ±0.94 nauplii/day and moulted five times in 31.2 days to reach the IV phyllosoma stage. But those fed with two day old nauplii consumed 19.3 ±1.6 nauplii/day and requiredud34 days to complete the fifth moult under similar environmental conditions.
