This document discusses the differences between recreational fishing and commercial fishing. Recreational anglers typically enjoy the outdoors and may bring home fish occasionally, while commercial fishermen rely on catching and selling fish as their livelihood. To be successful professionally, fishermen get advice from local experts, test different bait strategies to determine what species can be caught reliably in a given area, and either build a larger fishing operation or develop specialized techniques that work for their needs. The key is adapting methods through experience to optimize fish catches.
