Fish tug

is a type of boat that was used for commercial fishing in the first half of the 20th century, primarily on the Great Lakes and Saint Lawrence Seaway.

Fishermen soon began experimenting with enclosed cabins and net lifters, making the boats safer and more convenient on the inland seas.

The few fish tugs that remain in use today are largely objects of historical preservation efforts and not under commercial ownership.

A local historian operating the Instagram page @great_lakes_fish_tugs regularly documents the Canadian commercial fish tugs.
