Fish Mounds

Does anyone know which fish makes these mounds? Pictures taken at low water.

Eagle Lake, ME

Interesting. Never heard of anything like that and it seems pretty ambitious for fish. I figured a quick Google search would provide an answer but I came up snake-eyes. This is all I could find: http://www.themaineoutdoorsman.com/2011/04/mystery-rock-piles.html

From the sounds of that link it doesn't look like anyone really knows for sure what causes them.

Probably Semotilus coporalis (Fallfish or White Chub)

Well how 'bout that! Never would've thunk it.

I've been all over google and found a chub that make's a nest like structure. We saw 20-30 of these mounds on the Soper Brk and there are supposed to be some at the outlet of Indian Stream (both on the Allagash Water Way, ME)

And the answer is Chubs

I turned the question over to my Ace Research Assistant.
