Here's why:
* Passive voice: The sentence "fish get fished" uses the passive voice. While grammatically correct, the passive voice can be less clear and direct than the active voice.
* Redundancy: The word "fished" implies an action of fishing. "Fish" also refers to the act of fishing. So, the sentence is somewhat redundant.
Better Alternatives:
* Fish are caught. (Active voice, clear and concise)
* People fish for fish. (Active voice, emphasizes the action of fishing)
In general, the active voice is preferred in writing and speaking because it is more direct and engaging.
