the A to your Q is, it ranges by the type and size
Most fish do in fact have scales, even some with scales that are nearly microscopic in size; many catfish however do not have scales, they have armour plating, but not scales.
Yes they do.
No you can not it fish scales.
There are many ways in which scales assist a fish. The easiest one to explain and probably the most accurate to answer your question is that the scales are smooth and provide an aerodynamic facade, which helps them swim more efficiently.
No, a fish's scales do not shed as the fish grows larger. Instead, the fish's scales grow in size as the fish grows. The scales provide protection for the fish and do not need to be shed like skin or fur.
Fish scales do not tessellate, they overlap. Like most scales do.
Yes, Salmon do have fins and scales like most fish (although som fish, like catfish, do not have scales). I have never heard of a fish without fins, although eels have less fins than many other fish. The scales tend to be small and most fish vendors will sell salmon fillets with the skin and scales still on (although some people think the scales are unpleasant).
