Abstract
The catch composition of blue, porbeagle and mako sharks in New Zealand fisheries was assessed. The spatial and temporal distribution of catches was analysed for 2007−08 to 2010−11 using reported commercial data. Length-frequencies, maturity, sex and fin weight data were analysed from 1993 to 2012 using observer data. Sharks segregate by size and sex in New Zealand waters, leading to marked spatial variability, but other observed trends may be biased by trends in fisher practices.
