Weight and length data for fry

Weight (wt) and fork length (FL) data for fry in December, February, April, and July. A total of 15 fish were randomly sampled at each date (not same fish each time). Missing data points within a family indicate that no additional fish were alive in the family at that time point (or after that point).

本数据集包含12月、2月、4月及7月四个采样时间点的鱼苗体重（Weight, wt）与叉长（Fork Length, FL）数据。每个采样日期随机取样15尾鱼，且每次取样的个体并非同一批。家系内存在缺失数据点的情况，代表该家系在对应时间点（或该时间点之后）已无存活个体。
