Concurrent fixed and random site potting surveys NIWA document server Summary: The third fixed and second concurrent random site potting survey in the time series for Paterson Inlet. Sixty-three sites were surveyed (6 pots per site, 378 pot lifts) from 5 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 30-39%.
