Age and Growth of Chinook Salmon in Lake Michigan: Verification, Current Analysis, and Past Trends

摘要

The goal of this project was to assess the age and growth of chinook salmon in the Michigan waters of Lake Michigan. This goal involved three objectives: (1) to accurately determine and validate ages of chinook salmon taken from Lake Michigan, including fish caught by anglers and those taken by Michigan Department of Natural Resources (MDNR) survey; (2) to use age and size data to estimate growth rates of chinook salmon in Lake Michigan based on year class, sex, and maturity; (3) to use historical data to determine ages and growth rates of chinook salmon and compare them to current ages and growth rates.
