Abstract A pair of subadult Panulirus ornatus
was reared in the laboratory from July 2001. The female grew from 0.6 to
1.3 kg and the male from 0.5 to 1.6 kg in 2 years before the first mating
in July 2003. In 6 months, from July to December 2003, the pair mated and
spawned 3 times, producing 1.6 million eggs and 1.1 million phyllosoma larvae.
Mating occurred 25 and 63 days after moulting. The female spawned 2-3 days
after mating and the incubation time ranged from 23 to 27 days. The phyllosoma
larvae were released over 2 successive days. The growth rate reduced after
first mating in both the male and female and the female expended 42% of the
total weight gain for egg production.
