Chris, where did you see that? That directly contradicts everything that I
have seen out of Berkley research, which does make that statement about
Muskie. Bass do possess both rods and cones, and I believe you may be in
error here. From what I have seen, Berkley has always maintained that bass
are able to recognize blue into rather extreme depths.

Bob,

Bass definitely have both rods and cones, but from the research in
"Knowing Bass" he contended that bass cones were not sensitive to blue
light. I will re-read that part of the vision chapter, just to make
sure. But I had to read it 2 or 3 times myself originally. I don't
believe that is a matter that they cannot see blue at all, I think the
issue is more that they cannot determine shades of blue.

I will definitely re-read that section though, and directly quote it.

Thanks Bob,

Chris
