Early larval stages of the spiny lobsters, Panulirus homarus, Panulirus versicolor and Panulirus ornatus cultured under laboratory conditions

Abstract: 

Early developmental stages of the phyllosoma larvae of three tropical spiny lobsters, Panulirus homarus, Panulirus versicolor, and Panulirus ornatus have been described by rearing them. P. homarus phyllosoma grew to the V stage in 46-61 days. P. ornatus larva reached the IV stage in 32-36 days, while P. versicolor attained the same stage in 30-38 days. More than one or two moults were recorded between different stages, such as after II stage, in all the three lobsters. Early stages of phyllosoma larvae of P. homarus could be successfully reared in low salinity of 28 psu. The problems caused by epibionts like Leucothrix sp., Zoothamnium sp., Acinetasp., Epistylis sp. and Vorticella sp. are discussed. The features of the phyllosoma larvae were compared with the descriptions reported from plankton collections.
