Abstract

Mature red rock lobster, Jasus edwardsii were air freighted from the
North Island, New Zealand to Japan in 1985. During most years since,
egg extrusion has taken place during November and December and egg
hatching, from February to April. In the main experiment, phyllosomas
were cultured in 100-litre containers. Each container had an upwelling
system, connected either to a Nanno-chloropsis culture tank (Experiment
1) or to a coral sand filter tank (Experiment 2). Artemia nauplii
and mussel gonad were the main foods provided. The numbers of 1st,
5th, and 15th instars were 12 000, 1500, and 137 respectively in
Experiment 1, and 1500. 99, and 67 in Experiment 2. The intervals
between Instars 1-4 and 4-14 were 43 and 175 days respectively for
Experiment 1, and 43 and 169 days for Experiment 2. In Experiment
1, nine phyllosomas (13-15th instar) died during metamorphosis to
the puerulus and a single 17th instar metamorphosed 303 days after
hatching, 19 days later moulting into the juvenile. In Experiment
2, six 17th instar larvae metamorphosed 293 days and more after hatching,
with all dying over the following 3 days. In an ancillary experiment,
30 phyllosomas were cultured in each of two 30-litre tanks containing
microalgae: survival was higher, 20% and 43% reaching Instars 14/15
and six metamorphosing after 212-274 days. In all experiments, the
developmental sequence was generally consistent with that for larvae
from the field. Gill buds appeared at the 13th instar and gills were
complete at the 17th instar. Improved culture methods are required
to reduce late-stage mortalities.
