Download FAR 2012/21 Exploratory microchemical analysis of blue cod otoliths from potting surveys in Dusky Sound, Fiordland 2002 and 2008

Blue cod otolith trace element signatures showed 3 regions along Dusky Sound (DS) with distinct environmental signals. These varied among 5 strata overall, & between some strata at times. Multivariate signatures were driven temporally by Li B S Ba & spatially by B P Mn P. While only 23% of the total spatial variability among strata trace element signatures was explained, this was greatly increased by including region rather than stratum in the model.
