Fishingstead!

Yes. After considered thought, I believe I have found a loose term that answers the need for a word to stand in place of ‘fishing village’ (either marine or riverine).

It is cognate with roadstead (a sheltered stretch of water for boats) but suggests greater permanence of place (‘stead’).

Fishingstead.

Example: ‘There’s a little fishingstead down the cliff path in the cove, just a few cottages and boatyard.’
