Does anybody know why fish like bream or tench roll?. I have heard a few theories, but what are they doing?. Anyone know for sure?
PS i knew i could count on you guys for a sensible answer..
They mainly seem to roll in hot weather so, has it got to be something to do with temperature? Do they get a fillip of oxygen when they do it? I thought of some benefit in change of air pressure but then they would do it all year round. It has to be linked to temperature in some way I would have thought.
That's a weird one Chub-B.... bream following a duck around. I imagine carp do roll in winter but, it has to be more common in the summer months or in warm water temperatures but, bream do seem to roll prior to spawning as well. I still think it has to be water temperature related in some way. Would fish be able to gulp oxygen from the air? Could their gills work in this way?
