A young animal in its second year of life. The term is usually used in relation to relatively long-lived animal species in hunting, fisheries, etc. In fish farming, a yearling is an over-wintered calf with the first period of growth completed. The yearling may not have a full calendar year, and is marked with the number 1. Yearling is usually considered a fish until June of the year following the birth. Yearling is also called a spring fish that emerged from the spawn in late fall. The yearling usually has one yearling ring on its scales or, in early spring, no ring yet.
