Because a wild-caught animal puts a dollar value on a wild population which would otherwise have been worthless. Why hasn't Nile Perch been introduced into Lake Malawi even though it's been so wildly commercially successful in Lake Victoria? Because of lobbying from ornamental fish collectors (and the same collectors are right now trying to mitigate the destructive fishing resulting from nylon gill nets and trawls handed out by NGO's). Remember the indigenous fishermen who (briefly) stopped the Xingu dam? They were ornamental fish collectors, trying to protect their livelihood.
By contrast a malawi cichlid or zebrapleco bred in Germany provides no income to anyone in Africa or Brazil, and no incentive to preserve the wild populations.

Hobbyists (and western environmental organizations) tend to focus on the pet trade because that's what they see and it's an easy target, but if the pet trade was banned tomorrow the sum total effect on global extinction rate would be zero.
Furthermore wild caught is more environmentally friendly than captive bred.

Would local fishermen maintain their resource, or as the prices rose, would they in the words of the article "go in, get as many as you can, as quickly as you can, to make as much money as possible"?

Is this not simply because effects are rarely studied and quantified?

This only applies if the collecting is targeted and "ethical".

racoll wrote:Possibly. I believe any species with a wide enough commercial appeal to require heavy collections from the wild will invariably attract the attention of commercial fish farmers.

Mike_Noren wrote:Yes. I'm torn about that. It's good that breeders depress the price of very expensive fish, as very high price could motivate overfishing, but it's bad that they also remove the incentive to protect common & cheap fish species. On balance I suspect that from a conservation point of view commercial breeding is mostly bad.

The fish don't really need to be conserved, the habitat does. If there is no heavy fishing pressure, the fish will look after themselves, so long as suitable habitat exists. The onus on conserving the habitat should not solely lie in the hands of fishermen or aquarists, everyone needs to be involved.

Yes - and it's a lot easier to protect a habitat if it's filled with species representing a real value measurable in $, and generating income to the local population.

More or less the point MatsP made. The way I see it, there is nothing stopping farmers in the country of origin raising large numbers of fish. Yes, they're a bit behind the curve, but it is not too late if you can put a good product out in the market. One way to do this would be to provide artificial spawning habitats for fish and remove a percentage of the spawn for commercial use, to be raised in captivity to marketable size. Of course, this requires more involvement from the authorities and the use of people who know what they're doing.
Isn't Yann here involved in a captive breeding project in Brazil? I'd love to hear his thoughts on this as well.

Mike_Noren wrote:Yes, and that would contribute nothing to the preservation of the habitat.
It would perhaps be more fair, as people in the area of origin of the fish species benefited, but it would remove any financial incentive to protect the wild stock just as if the fish was farmed in Germany. Only wild-caught fish give value to the wild stock.
