Usage: Do not confuse the animal with the human term; a fisher is specifically a type of weasel-like mammal found in North America, whereas a person who catches fish is simply called a fisherman or angler.

An English occupational surname, from occupations for a fisherman.
"The town records show that several men named Fisher settled there in the late 1700s after inheriting their father's trade along the coast."
The word fisher comes from Old English fisċere and entered Middle English as fischer. It is derived directly from the word for "fish" combined with a suffix meaning one who does something, so its original sense of someone who catches fish has remained unchanged in modern English.
