A Comparison of Estimates of Natural Mortality from Fish Tagging Experiments
研究了专业渔民回收标记鱼类的实验，提出最大似然估计方法并推导方差公式，找到最优实验条件并识别可疑行为。
Tagging experiments in which recaptures have to be made by professional fishermen are considered. The methods put forward are shown to be maximum likelihood solutions, and expressions are derived for the variances of the estimators. Optimal conditions for the experiment are found, and cases of questionable behaviour are identified.
