Download FAR 2018/09 – Relative abundance, population structure, and stock status of blue cod in Paterson Inlet in 2014. Concurrent fixed and random site potting surveys

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%.
