The growth at moulting of crawfish Jasus tristani at Tristan da Cunha, South Atlantic

Growth increments of moulted crawfish Jasus tristani were recorded from animals tagged during 1971–73 at Tristan da Cunha, Nightingale and Inaccessible Islands in the South Atlantic Ocean. A decline in growth increment with size was observed for once-moulted animals of both sexes at Tristan da Cunha...

Description
Summary:Growth increments of moulted crawfish Jasus tristani were recorded from animals tagged during 1971–73 at Tristan da Cunha, Nightingale and Inaccessible Islands in the South Atlantic Ocean. A decline in growth increment with size was observed for once-moulted animals of both sexes at Tristan da Cunha, with mean carapace length increments for males and females of 5 and 1 mm respectively. Growth increments of this magnitude were similar to those recorded for the South African species Jasus lalandii , over a similar size range.
