Releasing Non Native Fish Into Reservoirs

[Shenanigans]

There are lots of examples on both sides of how it has worked and how it has destroyed the balance. It can be a good thing to introduce new species if you perform the needed research to know how it will react. And before someone points out that we will never know how it will truly react, we as humans jump the gun the majority of the time and do not fully research the impact it will have. Pbass have been introduced to florida for a sport fishery and to help control nonnative unwanted species. They have not had any negative impacts. Carp have also been added to consume unwanted vegetation growth without negative impact. Macroinvertebrates were added to Maine's Moosehead lake without proper research and it has all but completely collapsed the fishery.

Pros and Cons go both ways it just depends on if you want to actively change nature and let it go as it is. IMO not doing anything isnt much different since we already changed and destroyed the ecosystems without introducing nonnatives. Introductions can improve an environment

read the sticky... this topic has been debated for years on this forum. imo man messed it up first when we touched it.. second when we tried to buff out the fingerprint... im a very firm believer in sustainable harvests.. as natural habitates decrease population control is essential to avoid excessive inbreeding, or disease due to over population. I dont know of any intentional introduction of a non native that didnt do harm to the environment long term, invasive means bad.... not good.

Exotics in florida are linked directly to the zoo/ pet trade.. and hurricanes. do abit of digging and youll find some interesting things.

zebra mussles came in on ships bilge tanks.

snakeheads where intentionally introduced because of religious beliefs.

alot of the no natives in the US are not the Hobbys fault... but we are a convenient scape goat because we dont have the " power" other industries do.

edit : pbass have cross bred with the native black bass and all but erradicated the species.. majority are hybridized with pbass now.

carp eat all vegitation, and have destroyed many a Wi breeding grounds.

To me, I think its not a problem doing this...

then you don't understand. try doing some actual research on the repercussions.

pbass have not erradicated the species, and where is there evidence of hybridization between them and black bass? only asking because I have never seen one and I couldnt find one through google. And im talking about tripoldi carp, which is still used and protected in FL for their beneficial uses

Not trying to be controversial and saying that I support it. I do support it, but only with research to support it, I can only think of one or two examples of enough research being done and success. Its easy to think of dozens of failures. Ecology, the needed research, still has a long long way to go before we really understand ecosystems. We only think we know how "most" of it works

How many of you have dumped something into a lake back in the day without ever thinking.

This has been in debate since i don't know when... Fishes have been released into reservoirs in all parts of the world since, God knows when... The questions is, "Should we or should we not be doing this?" To me, I think its not a problem doing this... Carp and Snake Heads in the great lakes are just some freak occurrences... Nature should be able to take its course... Survival of the fittest...As it always has been.
Carp and Snakeheads will not survive long pr flourish in the frigid waters up north anyway... and in the Singapore reservoirs, the only thing destroying the eco-system is man....
Whatever kinds of predators introduced wherever, I think "Nature Will Take Its Course" and man's intervention is the one that really spoils all things...

So much wrong with this...

This. Done properly it can be beneficial, but often isn't and I don't feel it should be done intentionally without plenty of research to help ensure it won't very negatively affect the ecosystem

This thread is a ticking timebomb

Not all non-native species were harmful to the ecosystem (aka snakeheads, peacock bass and triploid grass carps) but there are few invasives that shouldn't be introduced to the Americas aka Asian carps. I once got hit by a large common carp while electro-fishing and it hurts like heck! Yes nature can adapt but you have to face the consequences.
