“…1). This hypothesis was supported by field surveys in the western North Pacific (Yoshimura et al 1999;Inoue & Sekiguchi 2001). Also, Sekiguchi & Inoue (2002) suggested that benthic populations of P. japonicus may be connected by a common pool of larvae, based on the above hypothesis.…”

Long-term annual variation in the catch index (CI) of Japanese spiny lobster Panulirus japonicus was examined in relation to the Kuroshio Current index (KCI). We identified two clusters (A, B) of the regions (prefectures) located east (A) and west (B) of Shionomisaki at the southern tip of Kii Peninsula, Japan. There was a significant positive relationship between the KCI at year t and the CI at year t+2 (2 years later) for cluster A. This relationship suggests annual variation in P. japonicus catch may be determined by the variation in puerulus supply through the Kuroshio Current. Relationships between the CI of these two clusters varied depending on 3 periods, which corresponded to 3 regime shifts: years before 1976, from 1977 to 1988, and after 1989. Significant negative relationships were detected between the CI of clusters A and B from 1975 to 2001, whereas a positive but non-significant relationship was found from 1965 to 1974. Annual variation in the CI of each cluster did not have a significant relationship with the presence/absence of the large-meander path of the Kuroshio Current.

“…Yoshimura (2005) had data (4 specimens) of finalstage phyllosomas of P. japonicus metamorphosing to pueruli in relation to the Kuroshio Current off southern Japan. Because mid-and late-stage phyllosomas were found in the ocean south of the Kuroshio, whereas most final-stage larvae were caught within this current (Yoshimura et al 1999(Yoshimura et al , 2002, Yoshimura (2005) inferred that metamorphosis occurs offshore within the Kuroshio Current as discussed above. Yoshimura (2005) also added that their Fig.…”

“…4. Yoshimura et al (1999) suggested that the finalstage phyllosomas of P. japonicus metamorphose to pueruli in the Kuroshio Current and the pueruli then swim across the Kuroshio Current to coastal areas to settle. But it is of interest that Yoshimura (2005) reported that ''when the Kuroshio is more than 100 miles [about 160 km] from the shore virtually no settlement of pueruli occurs.''…”

This review re-addresses the question: Where does metamorphosis to the puerulus mainly take place among the shallow-water palinurids? A decade ago we reviewed this ecological question in a paper that focused on phyllosomal development of the western rock lobster, Panulirus cygnus. The main region of occurrence of its metamorphosis was found to be in the slope region beyond the shelf break. Because the puerulus of P. cygnus is a non-feeding stage, it was hypothesised that metamorphosis will not occur until the final phyllosoma has reached some critical, and specific, level of stored energy reserves. For late larval development and successful metamorphosis of P. cygnus, the richest food resources seem to be located in the slope waters adjoining the shelf break off Western Australia. This, like most shelf break areas, is a region of higher zooplankton and micronekton biomass than is usually found further offshore, and is dominated (in winter-spring months) by the warm south-flowing Leeuwin Current. In this new review, distribution and abundance data of final phyllosomas and pueruli are examined from, Panulirus argus, Panulirus cygnus, Panulirus japonicus, Panulirus ornatus and Jasus edwardsii, and where possible, related to features of the satellite imagery of the areas in which they occur. We hypothesise that metamorphosis will occur where the final stages have partaken of sufficient, appropriate nutrition to provide them with a reserve of bioenergetic resources, and this can occur where oceanographic fronts effect greater planktonic productivity and concentrations of food organisms. This may be near the shelf-break, or out to large distances offshore, because of large-scale oceanographic events such as the prevailing current system, its off-shoots, mesoscale eddy fronts, counter-currents, etc. However, we contend that, in terms of population recruitment, metamorphosis in most shallow-water palinurid species occurs mainly in the slope waters adjoining the shelf break of the region to which the species is endemic. Although some final phyllosomas may metamorphose much further offshore, it is unlikely that these pueruli will reach the shore, let alone settle and successfully moult to the juvenile stage. All of the data indicate that successful metamorphosis from the final-stage phyllosoma to the puerulus stage in all species occurs offshore but close to the continental shelf.
