本文叙述了一种普遍接受的测量鱼鳃面积的方法。其中包括一些实用提示，以及一些关于可能的错误来源的警告。特别是，这些包括抽样方法和减少由于收缩而产生的误差。强调了称重在鳃面积计算中的重要性。讨论了在比较不同鱼类的鳃时出现的问题，并提请注意将所有数据简化为给定鱼的体重可能引起的错误。这种危险在鱼之间进行比较时尤其存在，因为鱼的重量可能相差4个数量级。
An account is given of a commonly accepted method for measurement of the gill area of fishes. A number of practical hints are included together with some warning about possible sources of error. In particular, these include sampling methods and reduction of errors due to shrinkage. Emphasis is given to the importance of weighing in the calculation of gill area. Problems which arise in comparisons of gills from different species are discussed and attention is drawn to possible errors that can be introduced by the reduction of all data to a given body weight of fish. Such dangers are especially present where comparisons are made between fish which may differ in weight by as much as 4 orders of magnitude.
