TL;DR: Complete larval development of spiny lobsters in culture has been achieved for cool temperate species and Jasus verreauxi may be suitable because of its potential for a high survival rate and Palinurus elephas is also an interesting possibility because ofIts short larval life.
Abstract: Complete larval development of spiny lobsters in culture has been achieved for cool temperate species, Jasus lalandii (H. Milne Edwards, 1837), Jasus novaehollandiae Holthuis, 1963, Jasus edwardsii (Hutton, 1875), Jasus verreauxi (H. Milne Edwards, 1851) and Palinurus elephas (Fabricius, 1787), and a warm temperate species, Panulirus japonicus (Von Siebold, 1824) since 1987. A good survival rate of about 10% was obtained for J. verreauxi. The factors important to the successful larval culture were: (1) introduction of microalgae into the culture water, (2) feeding with mussels and (3) supply of water from the bottom of the culture tank to induce a continuous circular current in the tank. The shortest duration of the phyllosoma stage for the above species, respectively, was 306, 319, 212, 197, 132, and 307 days. The number of instars was 17 for Jasus spp., 9 (estimated) for P. elephas and 25 (estimated) for P. japonicus. The shortest duration of the pucrulus stage was 19, 12, and 11 days for the above animals, respectively. Jasus verreauxi may be suitable because of its potential for a high survival rate. Palinurus elephas is also an interesting possibility because of its short larval life. Duration of the larval stage seems to be species specific. Within a species, it is affected by water temperature and food availability for the phyllosoma but exclusively by water temperature for the puerulus.

TL;DR: Fungal and bacterial pathogens present significant threats for rearing spiny lobsters in aquaculture settings, but only one pathogen, Panulirus argus virus 1, is thought to have damaged a fishery for a spiny lobster.

TL;DR: A reappraisal of the pelagic phase of development in palinurid lobsters, in conjunction with recent oceanographic data, shows that the ontogenetic changes in the vertical migratory behaviour of phyllosoma larvae operate as a biological strategy to effect larval recruitment.
Abstract: A reappraisal of the pelagic phase of development in palinurid lobsters, in conjunction with recent oceanographic data, shows that the ontogenetic changes in the vertical migratory behaviour of phyllosoma larvae operate as a biological strategy to effect larval recruitment. Wind-driven surface currents can transport the larvae in the opposite direction to the general circulation of the upper 300 m water layer. Ocean circulation charts are unreliable indicators of likely paths of larval transport because of their gross scale, lack of seasonal information, and the absence of indications of wind-driven surface currents. The majority of larvae are transported beyond the continental shelf to areas greater than 100 km offshore. This appears to be the principal source of larval recruitment to benthic populations, although some local recruitment from coastal areas may occur. Larval transport between populations of Jasus sp. in the Southern Ocean appears likely but is unconfirmed. For some insular populations this...

TL;DR: Activity of spiny lobsters during April-July appeared related to mating and any impact J. edwardsii have on prey populations will be restricted to near-daytime shelter.
