Allow me to throw in a couple of pennies.
In my opinion:
Collecting from the wild is not necessary in normal circumstances. Many
cultivars are available from native keepers. However there are regional
variations to consider. Once the gene pool is large enough among keepers
influx of native genes into captivity will become minimal. By the mere
fact of surviving in captivity artificial selection is begun. The only
way to completely mimic conditions in a stream is with a stream.
Existing habitat can be preserved by documented observation. Dead water
zones may be restored, providing habitat for critical species. This
should be done carefully with respect to any biology said restoration
will interact with, for instance connected non dead zones or flooding
event. "Collecting" sounds too wholesale. Try "Sampling" or somesuch.
What excuse is there for keeping wild fish that will not be given any
chance to breed? Keeping captive bred fish for pleasure does not seem to
be a problem for me.
