摘要通过对耳石剖面中的条带计数来确定hoki的年龄。该技术进行了验证，使用的进展长度模式的长度频率分布（年龄组0+至4+）和强，弱年类的年龄频率分布的进展，从商业渔获量采样的南岛西海岸，新西兰，从1988年至1994年。西海岸和库克海峡产卵种群的Von Bertalanffy生长参数显着不同，为两个种群的假设提供了进一步的支持。在这两个地区，雌性hoki的生长速度明显快于雄性，预期寿命也更长。
Abstract The age of hoki was determined by counting bands in otolith cross‐sections. The technique was validated using the progression of length modes in length‐frequency distributions (for age classes 0+ to 4+) and the progression of strong and weak year classes in age‐frequency distributions from commercial catches sampled off the west coast of the South Island, New Zealand, from 1988 to 1994. Von Bertalanffy growth parameters for the west coast and Cook Strait spawning populations are significantly different, providing further support for a two‐stock hypothesis. In both areas female hoki have a growth rate significantly faster than males, and also a greater life expectancy.
