Interesting that this is the conversation that has arisen.
I am valiantly telling someone on my fish forum not to release a local catfish into one of the lakes around here.
My argument is that since the fish was not only hatched, but also reared in captivity, and there is no knowing where exactly this was done and in what conditions. So yes, you may see that catfish in these lakes, but this catfish has been exposed to many other environments. And I am assuming this same instance applied to previous generations.
I guess I didn't think about my house being something that exposes them to something new. My friend is visiting and is from out of town, and that is another thing they are exposed to! She lives in NYC so there's no knowing the host of pathogens she brought with her.
I didn't think much about locally caught ants (local as in my backyard) being exposed to pathogens and the like since I'm dealing with the international fish trade as a baseline.
Don't release locally caught ants. I for one will be taking it as a lesson in responsibility and preparedness to do my best for the critters lives I decided to play god with.
