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.
