Jasus paulensis has been assessed as Data Deficient. This species was formerly known from a very restricted range (St Paul and New Amsterdam Islands), however a few recent specimens have been collected from other seamounts along the South West Indian ridge. This species faces a number of threats including intense harvesting within the St Paul and New Amsterdam Islands EEZ, and intrinsic threats associated with its small range. The abundance of this species outside of the current fishing grounds is unknown therefore making it difficult to draw any conclusions on the impact of fishing to the global population. Further surveys are needed for this species along the seamounts of the South West Indian ridge before a more accurate assessment of conservation status can be made.
|Range Description:||This species was originally only known from the St. Paul and Amsterdam Islands in the southern Indian Ocean, with a single specimen has also been reported from the Kerguelen Islands (Holthuis 1991), however recently additional specimens have been collected from seamounts along the South West Indian ridge (J. Groeneveld pers. comm. 2011). These indicate that the species is far more widely, but sparsely, distributed along the South West Indian ridge than previously thought.|

|Population:||There is no population information available for this species.|
|Habitat and Ecology:||Typically this species is found on rocky substrates at a depth range of 0-60 m, although is most commonly found in the kelp zone at a depth range of 10-35 m (Holthuis 1991). Females are most commonly taken from May to October, while males are most commonly taken from November to April (Holthuis 1991).|
|Major Threat(s):||The major threat to this species is high levels of exploitation. An intrinsic threat is this lobster's extremely restricted range. This species is also susceptible to environmental fluctuations for both adult and larval stages, and also to single catastrophic events.|
An annual fishing quota of 400 tonnes is in place for this species.
Further surveys for this species are needed along the South West Indian ridge in order to better understand both distribution and abundance.
