RE: NANFA-L-- Fish TB?

If I look-in-the emails from this list I notice that a lot of it deals with
collecting. SO... these wild caught fish have only been in the hobby for as
long as it has been since you caught them. When we talk of fish being "in
the hobby" I thought we were referring to generations of captive bred
animals. Having said this, some rainbows have been in the hobby for
probably close to 30 years. And since wild caught bows are hard to come by
for a number of reasons, many of the bows we have in the US come from a
handful of breeder stock. My guess would be that a fish's susceptibility to
a given pathogen would be dependent upon that species evolving with that
pathogen; be it in captivity or in the wild. Equally important may be a
given species susceptibility to stress.

Fish TB is bad news. There is no cure that I know of. It is easily
transferred throughout a person's collection through community nets, siphons
and such. If you have it in your collection you potentially distribute TB to
everyone who visits your fishroom and/or who receives any of your fish
and/or equipment. If you KNOW or even SUSPECT you have TB in your
collection and still distribute fish...well now we have a moral/ethical
debate on our hands!
