title: Seasonal and environmental codes in the chemistry of the scales of the hoki Macruronus novaezelandiae.
abstract: Hoki (Macruronus novaezelandiae: Merluccidae) scales do not have conventional annual (annuli) marks, but when observed by transmitted light showed light and dark bands of the type produced by intra-annual variation in the growth rate of the internal lamellae of the scale. The calcium, fluorine, strontium and zinc content of the hoki scale was measured with a proton microprobe and showed cycles in elemental composition that could be interpreted as seasonal.
