Answer:
The circuli of the cycloid scales are used to determine the age of the fish.
Explanation:
Cycloid scales are mainly found in the lower order teleost fishes such as salmon, carp and other soft fin fish. Cycloid scales are smooth in texture and uniform with smooth margin. As the result of growth of cycloid scales growth rings are developed which are called circuli. These circuli are equivalent to the growth rings of the tree. Circuli grows very slow during the cold season which creates a band called an annulus. The counting of these annulus are used to determine the age of the fish.
