Data from: An integrated population model for estimating the relative effects of natural and anthropogenic factors on a threatened population of steelhead trout

This collection includes data on the abundance, age composition, and harvest of adult steelhead trout, as well as the numbers of juveniles released from a hatchery, for steelhead trout (Oncorhyncus mykiss) from the Skagit River in Washington, USA. It also includes estimates of the marine survival of hatchery-origin steelhead.

本数据集涵盖美国华盛顿州斯卡吉特河（Skagit River）流域钢头鳟（steelhead trout，Oncorhyncus mykiss）的相关数据：包括成年钢头鳟的种群丰度、年龄组成与捕捞产量，以及孵化场放流的幼鱼数量；同时还包含孵化场繁育钢头鳟的海洋存活率估算值。
