Blastozooid growth experiment of Salpa thomsponi during RV Tangaroa cruise TAN1810 to the Chatham Rise, New Zealand

A mature Salpa thompsoni oozooid was collected using a so-called salp-net (1 m diameter ring net with 202 µm mesh fitted with a 30 litre non-filtering cod-end) at the Chatham Rise, New Zealand in October 2018. The growth of new-released blastozooid was studied in an experimental tank on-board for 5 days using image analysis. Growth rates were determined, which fell well within the range of earlier published rates, when temperature was accounted for.
