How can the age of a fish be precisely determined? (a) By its colour (b) By its scales (c) By its teeth

Answers

Answered by satyam21461

Counting the number of annuli (rings) on a scale provides the fish age and the spacing between rings is proportional to the growth of the fish. For some examples and uses of scale aging you can go to "Fish scales tell a story..." from the Delaware Division of Fish & Wildlife.
