@maxdancona,
ALL hunting has had a negative effect on species. I didnt want to get into an either or argument and I fer Ive been responsible for having sides get drawn up. Im a "meat" hunter and if we consider ten thousand hunters trophy hunting and 20000 meat hunters,soon it gets to be a real number (to quote Sen Sam Ervin). Trophy hunting serves no real "greater" purpose in any state because the money raised in upport doesnt do anything spectacular for species conservation , in fact, trophy hunting, by its definition , is like war,(It harvests our best).
Animals are showing effect of trophy hunting and fishing
1Overall numbers of most all target species have been greatly reduced since arrival of European
2Sizes of all target species have declined markwdly in 300 years. The really big (1000 lb to 1500 pound black bears) hve been eliminated all over.
3Game fish like swordfish, sailfih, and bluefin tuna have been reduced greatly in size and number as an obvious response to ovrfishing (sword and sailfish mostly as "trophy species", tuna from markt pressure.
4"Leaving alone" great fish species like Atlantic Sturgeon, paddlefish, pira rucu has helped in their very slow recovery.(In the case of sturgeon going caviar free has been the major rason)
The argument about game management is a fuckin lie that people, gullible to the last, will buy from the high marketing boys at state Fish n Game HQ's. Bison have gon from 20 MILLION on he plains to almost extinct to a post hunting number of about 250000(mot of whom are in private buffalo farms being raised for meat and about 30000 in National Park herds). Some privately owned bison have been farm raised and these too have shown really amazing adaptiv modifications in size, color, temperament etc. (Most of these have been crossed with Hereford cattle and whiteface cattle there is not true bison out there because of the "bottleneck" the species suffered when it was huntwed almost to wxtinction.
The recovery of bison has been an interesting story of genetic husbandry of an almost extinct species that was >effectively hunted out of being.
Imagine, subsistence (Meat and clothing) hunting by native Americans in an open plains environment has allowed the mega herds to be sustainably hunted (we think) for 10000 years. Then, in the space of 400 years, weve removed this entire species by hunting for pickled bison tongue. Then weve "hacked" a small herd or two by introducing canadian and Alaskan forest bison and then we mixed those with meat-breed cattle weve protected them for almost 125 yrs n were back to about 2% of the original herd size and as a totally different species.
Look at grizzly bear and puma. weve only got patches of these left and "leaving em alone" has been the real effective management program.
Thinking we can OUTTHINK, nature is hubris at its best.
