N2  - Third fixed and first random site potting surveys in north Otago time series. Twenty-seven fixed and 40 random sites surveyed (6 pots per site, 402 pot lifts) from 4 coastal and 2 offshore strata. Pot catch weighed, length and sex of blue cod recorded. Otoliths from random and fixed sites produced age-length keys applied to the scaled length frequency distributions to estimate the population age structures. Estimates of  Z and F%SPR indicate that spawning biomass has been reduced to 34-36%
