How do fish weight scales work?
When a fish is hung from the affixed hook, a spring lever is pulled downwards along a lined weight chart Another advantage of a spring scale is not having to rely on batteries for power They will work whenever you need them, as the power to run them is derived from the basic laws of physics
How do you read a fish scale?
In the field, scales are placed on waterproof paper, labeled and stored in a small coin envelope In the laboratory, a scale can be “read” by compressing it between glass slides and viewing the slides under a microscope Cycloid fish scales, like those of trout and salmon, add rings (‘circuli’) as they grow

How can you tell how old a fish is by scale?
Scales are the most widely used aging structure in North America because of their non-lethal ease of collection 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
Do fish scales have growth rings?
As the fish grows, the scales develop circular growth rings around the focus Each growth ring is called a circulus (plural: circuli) Like a tree, the fish grows faster during the summer when the temperature is warmer and there is more food available, and the circuli are spaced farther apart
How can you tell the age of a fish?
Biologists estimate fish age by counting these opaque zones, called annuli, just as one would count rings on a tree to determine its age For each species to which it is applied, the method of estimating age by counting annuli must be validated to prove that one whole annulus is equal to one year of growth
How do you read a digital weight scale?
