漁師

Etymology
The spelling is likely from compound. Compare modern 🇨🇬.

The expected reading would be gyoshi. The kan'yōyomi (irregular but customary reading) of ryō for the character is from confusion with the  character, usually read ryō in on'yomi contexts and meaning “, ”, as used in the homophonic term.

Noun

 * 1) a fisherman, someone who fishes as a livelihood
