Well Rick and Dianne here is one Nova Scotia fishing song which might lead to others specifically about the conflicts...

Western Boat
Let Me Fish Off Cape St,. Mary's

Take me back to my Western Boat
Let me fish off Cape St. Mary's
Where the hagdowns sail and the foghorn's wail
With my friends the Brown's and the Cleary's
In the swells off old St. Mary's.
Let me feel my dory lift
To the broad Atlantic cumbers
Where the tide-rips swirl and the wild duck furl
And the ocean calls the numbers
In the swells off old St. Mary's.
Let me sail up golden bays
With my oilskins all a-streaming
From the thunder squall where I hauled my trawl
And the old 'Cape Ann' a gleaming
In the swells off old St. Mary's.

Gordon Boks' Bay of Fundy from Folk Legacy (of course), has a number of such ballads...harpgirl
