In order to manage California's valuable fisheries resources, biologists need to gather information about fish abundance, growth rates, age, migrations, strain identification, and stocking success. One way to collect data is by attaching tags to planted and wild fish. Tagging can be done at a hatchery prior to planting in a California water or on location during a "catch and release" project.
