Default glow in the dark fishies

Actually, for some wild caught freshwater fish, having them caught for
the aquarium industry might be the only thing saving them. I don't
recall which species she was talking about, but Karen Randall
mentioned areas in South America where fish are caught and sold. In
those areas where they banned fishing (to protect the fish), suddenly
that land wasn't making any money, so the forests were cleared for
farming and other uses, which destroyed the habitat and killed off the
fish.


There were some live-bearers for sale at our last
fish club auction which are now extinct in the wild
due to habitat destruction.
I was actually thinking about the whole ethical
side of fishkeeping the other day.
I have to admit to feeling uncomfortable about wild
caught reef fish and inverts but I don't know enough
about the issue to make a judgment either way.
Is there such a thing as a 'happy fish' scheme so that
fishkeepers such as ourselves can be confident that
any livestock we buy has been treated humanely
and is either tank bred or comes from sustainable
wild populations?
If not then there should be.

One of the benefits of this hobby is seeing that we can sustain species that
are no longer found in the wild. Some top of the head examples would be
cherry barbs, black ruby barbs, and most Lake Victoria Hap's.
Some are so common and easily bred within the hobby that the chance of
extinction is remote. Others are maintained through specialty societies,
zoos, and scientific studies, so that perhaps a restocking can take place
once the causes for extinction in the wild have been corrected.
Reef or marine fish do not have the benefits of time, numbers of keepers,
and ease of keeping that freshwater fish have on their side. Yes, there are
firms that are actively involved in spawning experiments with marine fish
and invertebrates. Some are successful enough to offer the progeny through
retail outlets. But it will take a lot more time and study before many of
the marine life forms are self sustaining in captivity. Our hobby would be
a lot smaller if we had to wait for just tank raised fish.
Some tank raised fish come with 'certificates' of captive breeding. But I
imagine it is up to the individual hobbyist to be informed about the status
of fish they intend to keep, and to be experienced and knowledgeable enough
to provide a proper aquarium environment. The longer we can keep fish
alive, the less likely we need to purchase replacements, probably of wild
caught fish.
What you keep is indeed a personal decision. Just be informed.
