that sucks
but i have a bit of a hypothosis as to why the larger fish are becomming extinct, and they are all prehistoric, evolutionary inferioir to the modern day boneyfish
the thing is, the age of the dinosaurs is over, the gaints that once dominated our world are fading out, in a sort of effort on the part of evolution to adress overcrowding, the planet is only so big
yea it is humans contribution to their extiction but we are no longer simply another animal with which the beasts of old share the world with, no. we are now more of a force of nature than an animal, we are so far the pinnacle of evolution, and due to that, other species are being pushed out to make room
maybe?
or maybe im just a jerk who is totally off base
but trust me, i hate to see the ]v[onsters of the world fade away, they are a major reason this world is interesting to me. but i think just maybe, even if we compleely stopped fishing for or never started to, never altered the river, never tampered with the habitiat that these fish would still be on their way to extinction. just maybe. just a hunch.
