That's a good point, in fact any successful breeding of Barbel in a stillwater would probably be a problem for the health of the lake, let alone the fry, but for a fish to breed it has to have ideal conditions, we should appreciate that as anglers, however still water barbel do not breed, unless I am wrong, because it is not the conditions that Barbel need to breed,.
Doesn't answer the question Neil, why do they need to breed to thrive?
They are not Carp.
I don't understand your Human analogy, as barbel as all animals do breed by instinct, Humans do not, in other words animals make sure the environment can support offspring, as Barbel would.
Humans also breed by instinct as other mammals do, if we didn't our species would come to an end, I will try to put the question another way. people that are starving to death continue to breed, are they thriving because they breed?
