| Abstract | Complete development of phyllosomas wasaccomplished in Palinurus elephas, Panulirus japonicus, Jasus edwardsii and J. verreauxi. Larval development differsbetween species in duration and moult frequency aswell as morphology. The highest percent survival was obtained during the phyllosoma stage forJ. verreauxi. Phyllosomas of P. elephas were the mostdifficult to cultureregardless of the fact that they hatch at arelatively advanced stage. Culture experiments werecarried out to improve the percent survival of P. elephas. First instars of P. elephasexhibited vigorous predation upon the larvae ofJapanese sandfish Arctoscopus japonicus.Duration of the first instar was shorter at 12.8days when reared at 18 °C and percent survival wasapproximately 30%. Better results were obtainedfor first instars cultured in water inoculated withChaetoceros sp. and fed enriched Artemianauplii. Phyllosomas of J. edwardsii and P. japonicus were cultured without particulardifficulty. Most distinguishing features of P. elephasis the heavily setose six or seven longspines on the distal edges of the scaphognathite ofthe second maxillae while only four long spines arefound in other species. These facts suggest thatphyllosomas of P. elephas are initiallyplankton feeders and from first instar becomerapacious predators. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
