    Abstract

    Berried lobsters collected from landing centres and lobster holding centres were used for larval rearing of the spiny lobsters, Panulirus homarus (Linnaeus, 1758), Panulirus ornatus (Fabricius, 1798) and Panulirus versicolor (Latrielle, 1804). Fecundity of the lobsters used for larval rearing was calculated as the number of eggs deposited on the ovigerous setae on the pleopods. The number of eggs in a single brood ranged from 1,20,544 to 4,49,585 in P. homarus. 5,18,181 to P.ornatus 1,979,522 and that of P. versicolor as 1,70,212 to P.versicolor 7,33,752. The tropical lobsters are reported to and therefore breed two times or more in a year. The absolute (annual) fecundity of these lobsters is expected to be higher. The phyllosoma larvae released, as percentage of fecundity, was maximum in P. homarus 85.7, 49.7 in P. ornatus and 74.0 in P. versicolor. Handling of lobsters at the landing and holding centres and aerial transport resulted in high percentage of eggs in arrested development, complete or partial shedding of eggs and release of weak phyllosoma larvae. Severe bacterial infection leading to complete shedding of eggs was recorded in a few breeders collected from holding centres.
