The Palinuridae arose in the Atlantic-European region during early Mesozoic at a period of high sea level in the vast, warm 'Super Tethys' Ocean. During the Tertiary, equator-ward movements of the African, South American, and Australian Plates have subdivided the Tethys, created and expanded the Southern Ocean, and thus produced a multitude of separated environmental habitats in all the major oceans of the world. The family diverged in the Jurassic into the Stridentes group, seven genera of which survive today in the low-latitude equatorial zone, and the Silentes group, three genera of which live today in the mid-latitude temperate zone of the Southern Ocean and one genus in the equatorial zone. The older extant genera in both groups generally live in relict habitats at the greatest depths and the younger genera have radiated into the many new shallow-water habitats. Two major lineages within the Stridentes genus, Panulirus, are recognized, the older lineage living in the clear, cooler, more stable subtropical zone and the younger living in the warmer, turbid, more rapidly evolving tropical zone. Two major lineages are also recognized in the Silentes genus, Jasus, one lineage living on the continental shelves of Africa, Australia, and New Zealand and the other living on the isolated volcanic islands and sea-mounts of the southern subantarctic zone. RÉSUMÉLes Palinuridés sont apparus dans la région Atlantico-Européenne au cours du début du Mésozoïque à une période ou le niveau du vaste et tiède océan "Super Téthys" était élevé. Durant le tertiaire les mouvements des plaques de l'Afrique, de l'Amérique du Sud et de l'Australie vers l'équateur ont subdivisé Téthys, créant et développant l'Océan Méridional et produisant une multitude d'habitats environnementaux séparés dans tous les grands océans de la terre. La famille a divergé au Jurassique entre le groupe des Stridentes dont 7 genres survivent aujourd'hui dans les basses zones équatoriales et le groupe des Silentes dont 3 genres vivent de nos jours dans les latitudes moyennes de la zone tempérée de l'Océan Méridional et 1 genre dans la zone équatoriale. Le genre le plus ancien dans les 2 goupes habite en général dans des habitats reliques dans les plus grandes profondeurs et le genre le plus récent a radié dans les nouveaux habitats de faible profondeur. Deux grandes lignées sont reconnues dans les Stridentes, Panulirus la plus ancestrale vivant dans les zones 1 )

The eastern rock (spiny) lobster, Jasus verreauxi occurs along the east coast of Australia and North Island of New Zealand. The resource off New South Wales (NSW), Australia, is managed through a suite of input controls and individual catch quotas. The stock assessment process has identified that the length-based model used in annual stock assessments would be improved with more precise information about the species' growth patterns. This study provides the first published information on a growth model for this species by describing the results of tagging experiments from 1995 to 2001 (inclusive). Lobsters were tagged with anchor tags across six locations spanning the main distribution of the species off NSW. The maximum time that a tagged lobster was at liberty was 2573 days. Recapture data were fitted to the von Bertalanffy growth function (VBGF) using Fabens method, including parameters for seasonal growth and individual variability in growth, and extraneous information about the average length and age of puerulus larvae so that the parameter t 0 could be calculated. Males had a longer predicted mean growth increment at 98 mm antennal carapace length (CL) and 202 mm (CL) (g α and g β , the two input sizes used in the model) than females. Transformed values (with CI) for the VBGF parameter K were 0.13 (0.12-0.16) and 0.14 (0.12-0.15) for females and males, respectively. Respective values for the VBGF L xj were 239.77 (224.37-243.51 mm CL) and 246.10 (244.69-280.70). The eastern rock lobster is amongst the largest of the palinurid family. The species is exploited for approximately 4 years before reaching sexual maturity (approximately 8 years of age) and for approximately 3 years after that time until the legal maximum length is attained. These exploitation circumstances expose this longlived species (approximately 30 years) to the risk of recruitment overfishing and consequently this risk is assessed annually through a stock assessment process.

“…The eastern rock lobster is also found off New Zealand, predominantly around the North Island (Kensler 1967a). Genetic studies have shown that the stocks off Australia and New Zealand are discrete populations (Brasher et al 1992;Ovenden & Brasher 1994).…”

Catch per unit effort in the fishery for eastern rock lobsters peaked in 1971Á72 and then declined until 1992Á93. In response to this pattern, a management package consisting of individual catch quotas, restricted entry and a legal maximum length was imposed upon the fishery. The effectiveness of these management measures to rebuild the eastern rock lobster population has been monitored annually through data collected from surveys of puerulus larvae abundance, fishery independent surveys, a compulsory logbook, observer surveys and biological studies. The total allowable commercial catch (TACC) is set annually by the TAC Committee after considering submissions from the public and industry and an annual report for the lobster fishery. The annual report prepared by government consists of an appraisal of the performance of the fishery against the objectives of the share management plan and goals of the fishery management strategy for the rock lobster fishery and includes a formal stock assessment. The trigger points behind the objectives and goals relating to the status of the stock have not been activated in the 2010Á11 year. Total biomass and exploitable biomass have increased, spawner biomass has increased to now be above 25% of the pre-exploited biomass and the relative abundance of recruits (puerulus larvae) to the population is increasing. The stock is considered to be rebuilding and the resource now supports a viable fishery with an increasing share price.
