Description The first successful advanced (stage VIII) larval development of the tropical spiny lobster,
Panulirus homarus L. under laboratory culture has been achieved in a short span of 42 days.
The culture treatments were maintained in two different systems, one with microalgae,
Nannochloropsis salina (30-40 million cells/mL) and the other without microalgae.
Phyllosoma attained stage VIII (5.25 mm) and stage V (3.36 mm) with an intermoult period
of 4-6 and 5-9 days in the two systems respectively. The larvae moulted nine and six times
in the microalgal and non-algal systems, respectively. Phyllosoma were fed with freshly
hatched live Artemia salina nauplii (0.32 mm) for an initial period of 10 days, followed
by juvenile Artemia (1.45 –1.54 mm) enriched with microalgae for the subsequent 15 days.
Artemia enriched with commercial polyunsaturated fatty acid concentrate (DHA-Selco) was
fed to the larvae for the rest of the culture period. Salinity and temperature were maintained
at 33 ± 2 ppt and 28 ± 2 0C, respectively, while the pH recorded an optimum of 7.9 ± 0.5.
The microalgal larval rearing system had lower bacterial load (total heterotrophic marine
count, 1.0 X 103 CFU m L-1 and total Vibrio sp. count, 20 CFU/mL) compared to the nonmicroalgal
system.
