RESUMO
The early stages of the Panulirus echinatus were hatched and reared in the laboratory. Ovigerous females were captured in their habitat and carefully transported to the laboratory. Larvae were transferred in a recirculation water tank at a density of 10 larvae.L-1. The larvae were fed on Artemia and gonads of mussel Brachydonts sp. Microalgae Dunaliella viridis was added at a concentration of 150 x 10(4) cell.mL-1. Larvae and exuviae of each zoeal stage were preserved in an alcohol 70 percent + glycerin (1:1) solution. The phyllosomas moulted eight times; the intermoulting period of each instar averaged about 7 to 10 days. The main morphological changes of each appendage were described in detail, illustrated and compared with previous reports.
Os estágios iniciais de lagosta tropical Panulirus echinatus eclodiram e foram cultivados em laboratório. Fêmeas ovígeras foram capturadas em seu habitat e cuidadosamente transportadas para o laboratório. As larvas foram cultivadas em tanques de recirculação de água e alimentadas com náuplios de Artemia e gônadas mexilhão Brachydonts sp. Microalga Dunaliella viridis foi adicionada em cada tanque de cultivo na concentração de 150 x 10(4) cel.mL-1. Os filosomas mudaram oito vezes e o período de intermuda de cada instar foi de cerca de 7 a 10 dias. As principais mudanças morfológicas de cada apêndice foram descritas, ilustradas e comparadas com trabalhos anteriores.
