The Ecological Ramifications of Disease and Density in the Caribbean Spiny Lobster, <i>Panulirus argus</i>
… virus known to be pathogenic to any species of lobster. HLV-PA is a pathogenic herpes-like virus that infects juvenile Caribbean spiny lobster, <em>Panulirus argus</em>, in the waters off south Florida (USA), and it alters the behavior and ecology of this species in fundamental ways. Gross signs …

The rise and fall of the spiny lobster (Jasus edwardsii) in the Hauraki Gulf, northeastern New Zealand
The spiny lobster (Jasus edwardsii) is a critical sea urchin predator on Australasian rocky reefs. In New Zealand, J. edwardsii also supports the country’s most valuable inshore commercial fishery, and subsequently is subjected to intense fishing pressure. While marine reserves have long been shown …

Potential of a trap-fishery for the spiny lobster Palinurus delagoae off eastern South Africa : has the stock recovered?
An experimental trap fishery for the deep-water lobster spiny lobster Palinurus delagoae commenced in 2004, and was run until 2006. Data collected by on-board scientific observers were used to explore fishing effort, catches and catch per unit effort. The recent data were compared with those for a …
