从一系列的耳石照片的37鳗鱼捕获在一段150米长的河流的测量被用来准备的生长曲线的基础上反算的测量。L∞= 1045，K = 0.046。平均增量增长计算为33毫米，每年同意密切从观察到的增长4年后，从同一地点标记鳗鱼确定的增量。根据燃烧的耳石年龄测定的结果中的inanimation的描述，但它的结论是，该技术产生足够的可靠性，可用于实际管理情况的结果。
Measurements taken from a series of photographs of otoliths of 37 eels caught in a stretch of river of 150m length were used to prepare a growth curve based on back-calculated measurements. Values of L∞= 1045 and K = 0.046 were determined. Mean incremental growth calculated as 33 mm per year agreed closely with increments determined from growth observed up to 4 years after tagging eels from the same location. Inconsistencies in results of age determinations based on burned otoliths are described but it is concluded that the technique yields results of sufficient reliability to be used in practical management situations.
