Finding Fish and Fish Finders

Vic came up to go ice fishing. Now, on Sunday he sat out there for about four hours, watching the slush around the ice hole, and pondering the error of his fishing ways.  The fish finder, hovering in the dark depths below the ice, indicated that there were no fish in the sea. None at all. 

Four hours of jigging the line and pondering the line and he called it a day. We went out to dinner, at Muskoka on the Rocks. (excellent choice, by the way, with or without fish on the menu)

Monday, fueled by a breakfast of free range eggs, our intrepid hunter gatherer set out again.  Two hours later, he had these beauties.  And he had caught and released two more. The fish finder, on Monday morning, indicated fish by the hundreds. Or at least, very very many fish.

Perhaps they commute through the bay?
