I don't think a RSBD is going to pass up a nice steak dinner just cause
someone said they're algavores :) It's interesting tho. I wonder if it's
not some other selective pressure? Perhaps the population hasn't recovered
from leaner years (ie the selection was for smaller body size instead of big
brutes by spawn season)?
