Abstract
This report assesses the catch composition of shortfin mako sharks taken by surface longlines in New Zealand waters. Length-frequency distributions, maturity and reproductive status were assessed from observer data. An ageing protocol was developed using vertebral sections, and growth curves and a scaled age-frequency distribution of the catch were generated. The proportions of mature sharks caught were estimated.
