Plate 7. Rock lobsters (Jasus sp). 



In the Southern Ocean no benthic invertebrates are commercially harvested. However, 

 within the wider area considered here, rock lobsters of the genus /axux are currently exploited 

 to a marked extent. At the Tristan group of islands (Tristan, Nightingale, Inaccessible, and 

 Gough) and at Amsterdam/St Paul they have been exploited for a number of years, and for 

 both groups of islands catch and effort statistics are available. The size composition of the catch 

 and the production by tail size category have been recorded. Fairly good data on growth of 

 rock lobsters at the Tristan group have been obtained from tagging experiments, which are to 

 be continued. Analysis of size composition data has been attempted to evaluate growth rates at 

 Amsterdam/St Paul, but the results need verification by other techniques.
