Final answer:
Determining the age of a fish can be aided by factors such as the presence of growth rings on the fish's scales, the size of the fish, and the number of scales on the fish.
Step-by-step explanation:
Determining the age of a fish can be aided by several factors. One of these factors is the presence of growth rings on the fish's scales. These growth rings, also known as annuli, form on the scales as the fish grows older. Each growth ring represents one year of the fish's life. By counting the number of growth rings, scientists can estimate the age of the fish.
Other factors that can aid in determining the age of a fish include the size of the fish and the number of scales on the fish. Generally, larger fish tend to be older than smaller fish, and a greater number of scales can indicate a more mature fish.
